    With no end in sight, Elizabeth Weise of USA Today reports that suspicions are mounting that fresh unprocessed tomatoes aren't necessarily causing the salmonella outbreak that has sickened 851 people across the U.S., with the latest case beginning June 20.

    Robert Tauxe, deputy director of the Centers for Disease Control and Prevention’s division of foodborne diseases, said CDC launched a new round of interviews over the weekend, adding,

    "We're broadening the investigation to be sure it encompasses food items that are commonly consumed with tomatoes.”

    Weise reports that if another food is found to be the culprit after tomatoes were recalled nationwide and the produce industry sustained losses of hundreds of millions of dollars, food safety experts say the public's trust in the government's ability to track foodborne illnesses will be shattered.

    Michael Osterholm of the National Center for Food Protection and Defense at the University of Minnesota, said,

    "It's going to fundamentally rewrite how we do outbreak investigations in this country. We can't let this investigation, however it might turn out, end with just the answer of 'What caused it?' We need to take a very in-depth look at foodborne disease investigation as we do it today."

    Jim Prevor, editor of Produce Business magazine, says tomatoes couldn't have caused an outbreak that has stretched from early April to late June.

    "There's not a field in the world" that produces that long.

    If not tomatoes, what else? "Something that people find difficult to remember but which is always served with tomatoes," says Tauxe.

    That would put salsa, jalapeño peppers, green onions and cilantro at the top of the list of potential culprits, says Doug Powell, director of the International Food Safety Network at Kansas State University in Manhattan, Kan.

    Ever wonder what to do in an ice storm. A tornado? How about a flood? Living in the Midwest, we get everything.

    Now imagine it’s not just you and your family. It’s a restaurant, a store, even a really big store.

    The Conference for Food Protection (CFP) has released “practical guidance for retail grocery and food service establishments to plan and respond to emergencies that create the potential for an imminent health hazard.”  It includes a list of on-line resources.

    It’s a great starting point.

    A pomegranate salad, a Frozen Sangria Rita and an oxygen facial.

    According to the Arizona Republic, these are the ingredients for a more youthful appearance, and restaurants are jumping on the trend by offering antioxidant-rich dishes.

    Annika Stensson, spokeswoman for the National Restaurant Association, said the association recently conducted a survey asking more than 1,200 professional chefs in the United States to list the trendiest items on their menus. Out of almost 200 items, pomegranate finished 16th, fresh fruits were 61st and scallops were 100th. All are foods rich in antioxidants.

    The interest in antioxidants also has been transforming beverage lists. Trudy Thomas, director of beverages for Camelback Inn, said the resort created an antioxidant-rich margarita, the Frozen Sangria Rita, after guests expressed interest in red wine's antioxidant qualities.

    Since its debut in February, the concoction of red wine, pomegranate and blueberry has been one of the most popular drinks on the menu, she said.

    Diane Aiello, owner of Glam Lounge in Scottsdale, said,
     
    "I am a huge believer in antioxidants. … When we do an oxygen facial, we can see the person's skin actually changing. The skin is more hydrated, more plump, and lines are softer."

    Madonna is said to be a fan.

    The Dallas Morning News ran a couple of excellent features on the flow of food from Mexico to the U.S. Yesterday's story was about the lack of inspectors, how little product was actually inspected, and, perhaps unwittingly, the problem of inspecting fresh produce for microbial contaminants.

    “In December, officials took a sample for testing from a 5,500-pound load of Mexican basil moving through the Otay Mesa border crossing in San Diego. The basil continued on to its destination and was sold to restaurants and other customers in California, Texas and Illinois the next day. When the test results came back two weeks later, they suggested salmonella contamination, sparking a late recall.”

    It's much better to design safety into all operations, beginning on the farm.

    Glenn Fry helps run Taylor Farms de Mexico's new $14 million plant in San José Iturbide, Mexico. He picked the land where it sits, designed just about every facet of it, and he manages more than 800 workers who plant, harvest and package produce – including lettuce, onions and broccoli – for export to the U.S.

    Today’s story says that Taylor Farms is just one of a handful of U.S. companies lured by Mexico's ideal year-round growing climate, proximity to Texas, low labor costs and plentiful workforce.

    During a recent lettuce harvest, quality-control supervisor Laura Patino pointed to an aide who monitors workers coming out of the mobile toilets at the end of the fields to make sure they wash their hands before returning to work.

    "Many of our workers don't even have toilets at home, so this is new to them," Ms. Patino explains. "We've literally taught many of them how to go to the restroom. It's that basic."

    The lettuce field – owned by Oscar A. Bitar Macedo and leased by Taylor – is fenced off from outside "contamination." Heavy strips of yellow plastic keep out dogs, cattle and other livestock.

    Mr. Bitar, owner of Rancho Don Alberto, leases all of his 100 hectares (about 247 acres) to Taylor. And he's responsible for maintenance, water wells, monthly water testing, fencing, security guards and, yes, even toilet paper. …

    Within two hours, 24 boxes, each holding about 850 pounds of lettuce, are transported to Taylor's plant a few miles down the road for the first of several safety checks.

    At the entrance, 19-year-old Efigenia Rosas checks the boxes to make sure they're labeled with bar codes identifying the owner's farm, crew supervisor, field and time of harvest – a crucial step in the process. If a consumer later finds a problem, Taylor can trace the produce back to the field and farmer. …

    At 6 p.m., driver Roman Ayala, an employee of Flensa Trucking, begins the drive north on Mexico's Highway 57. He's in no rush because he has no chance of getting to Nuevo Laredo before Customs shuts down the bridge at 11 p.m. And it won't reopen until 8 a.m., something that frustrates Mr. Fry to no end.

    "How can the U.S. government be serious about food safety when they shut down the border overnight and perishable goods have to sit there and wait?" he asks.


    There is also a good video overview of the lettuce harvesting procedures available along with the story at http://www.dallasnews.com/sharedcontent/dws/news/world/mexico/stories/063008dningproducttaylor.40d72a3.html

    Julie Schmit reports in USA Today today that,

    Last July, Food and Drug Administration officials issued a rare warning to U.S. consumers: Botulism toxin was suspected in hot dog chili sauce made by Castleberry's Food.

    The botulism outbreak, which would eventually sicken eight and lead to a recall of tens of millions of cans of food, was the first in a U.S.-made canned food in 33 years.

    The day before the warning, FDA investigators had begun an inspection at a Castleberry's plant that set off alarms within the agency.


    A previously undisclosed report from FDA that USA TODAY obtained from a congressional committee concluded:

    • two 10-foot-tall cookers may not have heated cans enough to kill all bacteria, including those leading to botulism toxin;

    • the cookers had broken alarms, a leaky valve and an inaccurate temperature device;

    • the FDA criticized Castleberry's for failing to correct problems, but those problems went undetected by FDA inspectors at the plant five months before the outbreak and by Department of Agriculture inspectors who were in the plant weekly; and,

    • the cookers in the Augusta, Ga., plant showed "poor maintenance," and management failed to "correct ongoing deficiencies" in the plant. "Failure in management was ultimately the reason for the … botulinum toxin in the cans," according to the report.

    Donald Zink, a senior FDA food scientist, says in the story,

    "When you have a firm that fails so badly that they produce cans with Clostridium botulinum … there are invariably multiple process failures, multiple violations … and failed management systems.”

    The Sydney Morning Herald reports that coroner Jane Culver has found that a Sydney restaurant served asparagus sauce contaminated with bacteria in January last year, leading to the death of William Hodgkins, 81, because of slack procedures in its handling of the sauce.

    The sauce, which was served with the fish of the day at Tables restaurant in Pymble on January 12, 2007, had 9.8 million colony-producing units of Bacillus cereus per gram.

    Ms Culver said the sauce was made at 3pm the day before, on January 11, and refrigerated. It was taken out of the refrigerator on January 12 but not discarded after four hours of use. Four hours is the recommended amount of time for the sauce to be used after being refrigerated, Ms Culver said.

    Instead of being thrown out, it was placed in a coolroom so that it could be used for serving meals.

    Ms Culver said the container for the sauce had no label showing when it was made or when it should be discarded.

    Barack Obama may be the change candidate but his food safety rhetoric falls into a tired and unsubstantiated pattern.

    Obama wrote on Friday in a letter to  Cow Calf Weekly (great reading for the beach),

    “America continues to have the safest, most abundant and cheapest food supply in the world. … Beef producers are a key component in a healthy and vibrant rural America. By strengthening USDA and working to enhance food safety and meat processing, my administration will assist the industry in providing a wholesome and safe product to your customers.”

    Maybe Barack is using the same PR folks as the Taste of Chicago. And with over 800 people sick from Salmonella in tomatoes and no source in sight, is it really the right time to be making claims about who has the safest food?

    Thanks to Kansas State PhD student Charles Dodd for forwarding the item.

    Deborah Shelton of the Chicago Tribune gave me a call Friday morning before spending the day with a food inspector at the annual Taste of Chicago event, expected to draw some six million people.

    Last year, some 800 visitors to the Taste were sickened with Salmonella, traced to hummus served at the Pars Cove Persian Cuisine booth. It may have been the sesame seeds, or tomatoes, in the hummus; it may have been a hand hygiene issue.

    "Handwashing, avoiding cross-contamination and monitoring food temperatures are important efforts, but for a lot of foodborne illness, these aren't enough," said Doug Powell, scientific director of the International Food Safety Network based at Kansas State University. "What people are missing is that many of these outbreaks are caused by foods contaminated at their source."

    Last year, I said the Chicago Department of Public Health engaged in “a breathtaking example of doublespeak,” and “what is possibly the biggest piece of PR puffery I've ever seen” as the Department insisted:

    "The Pars Cove situation represents the first confirmed outbreak of illness associated with the event in at least 20 years. In the larger context of having safely served tens of millions of people in recent years, the Taste remains quite possibly the safest food service operation in the city."

    The sick people were probably interested to know they were a statistical anomaly.

    But it continues.

    Dr. Terry Mason, commissioner of the Chicago Department of Public Health, said yesterday,

    "The Taste of Chicago is the most highly regulated, tightly scrutinized event in the city, perhaps even in the nation."

    Mason said food inspections will take place at booths four times a day to ensure the public's safety.

    "One case of illness is one case too many, but the fact remains that no other major outdoor food event in the nation has a better track record of safety than this one.”


    Show me the data. Or show the data to the 800 sick people from last year. And, Dr. Mason, you can inspect 20 times a day; until you have a plan to verify that raw ingredients are coming from safe – or at least microbiologically aware -- sources, your Taste is a vulnerable to foodborne illnesss as any other eating event.

    Sure, asking questions is hard. But public health inspectors are ideally suited to ask those hard questions. Restaurants that want to avoid Bill Marler need to be able to answer those questions.

    Starpulse.com reports that Mike Myers realized he was ill on his way to his Love Guru premiere in Australia earlier this month and had to stop at a number of restaurants to use restrooms before he actually got to the premiere.

    "In Australia, when you go into a drug store you actually have to talk to the pharmacist...I was looking around and I was, like, 'Hi!' 'Hello, you're Mike Myers, how are you? What can I do for you?' (I said) 'I'd like Pepto-Bismol please.' 'We don't know what that is...What is it exactly, Mike?' I was like, 'It's for tummy trouble.'"

    But the confused Aussie staffmember at the pharmacy needed him to be more specific, prompting a desperate Myers to reveal he was suffering from diarrhea.

    He adds, "(They said) 'How very interesting, you're a superstar with diarrhea.' I'm like, 'Hmmm, don't feel like a superstar right now.'"


    No indication if the cause was food or water related, but hey, Mike, we’ve all been there. Not messing around on a bed with Madonna or cavorting with Beyonce, but we’ve all had the runs.

    Best Mike Myers role? So many good lines and characters from the Toronto-area funny man, but the best is the Don Cherry-inspired hockey announcer on the vastly underrated Russell Crowe vehicle, Mystery, Alaska.

    And that’s Dr. Evil to you. I didn’t spend all those years at Evil University to be Mr. Evil.

    The U.S.Center for Disease Control and Prevention reports that since April, 810 persons infected with Salmonella Saintpaul with the same genetic fingerprint have been identified in 36 states and the District of Columbia.

    The number of ill persons identified in each state is as follows: Arkansas (10 persons), Arizona (39), California (10), Colorado (8), Connecticut (4), Florida (1), Georgia (18), Idaho (3), Illinois (78), Indiana (11), Kansas (14), Kentucky (1), Maine (1), Maryland (25), Massachusetts (18), Michigan (4), Minnesota (2), Missouri (12), New Hampshire (3), Nevada (4), New Jersey (4), New Mexico (85), New York (25), North Carolina (5), Ohio (6), Oklahoma (19), Oregon (7), Pennsylvania (6), Rhode Island (3), Tennessee (6), Texas (342), Utah (2), Virginia (22), Vermont (1), Washington (4), Wisconsin (6), and the District of Columbia (1).

    Among the 523 persons with information available, illnesses began between April 10 and June 15, 2008. Patients range in age from <1 to 99 years; 51% are female. At least 95 persons were hospitalized. No deaths have been officially attributed to this outbreak. However, a man in his sixties who died in Texas from cancer, had an infection with the outbreak strain of Salmonella Saintpaul at the time of his death. The infection may have contributed to his death.

    Earlier this month Doug talked about entomophagy, the practice of eating insects as food. It’s no mystery that many cultures eat bugs for nutrition.  However this is not the case for the cultures of the United States and Europe, where not only are bugs unappetizing, but there is an entire market devoted to their extermination.

    Western culture has put a certain social taboo on insects in general.  If a cockroach is found in a kitchen of a restaurant, health inspectors will shut the place down.  But who can blame them?  Most Americans are brought up to find bugs disgusting and dirty.

    As part of an introductory entomology class in my undergraduate work, I had the chance to try cookies containing dried crickets and salsa containing live mealworms.  I definitely was not excited about tasting either of them, but you would be surprised what some students would do for extra credit.  After sampling the supposedly “tasty treats” I have to admit that they weren’t half bad; in fact they tasted completely normal.

    Just as a cook might add tofu to a noodle dish, there is also the option of earthworms or grasshoppers for an extra dose of protein.  And a large number of countries have a booming market for raising insects, just as there is a market here in Kansas for raising beef cattle.

    Not only would there be a little more variety in food options, but also the option to “go green” in other ways than driving a hybrid.  Multiple studies and articles have been written about how insects are much more efficient converters of energy compared to typical farm animals.  Bryan Walsh of Time.com has a terrific article about how environmentally friendly insects can be used as a food source.

    Now I’ve read the articles too, but the first large hurdle to jump over will be the cultural taboo.  The food industry of Western culture will have a hard time changing “Waiter, waiter, there is a fly in my soup!” into “Waiter, waiter, I do not have enough flies in my soup!”

    As I've blogged before, I'm interested in the intersection of disparate ideas.

    Today's intersection relates to the good folks at Barf Blog, and the cross-country adventures of a fellow food safety microbiologist.

    Many professional food safety scientist readers of this blog may know Dr. Tom Montville. He's the coauthor of Food Microbiology: An Introduction and co-edited the first two editions of Food Microbiology: Fundamentals and Frontiers.

    But the reasons for this post don't have too much to do with food safety, although they do have a lot to do with food, more specifically food security.  And when I say food security, I don't mean defending the food supply against bioterrorism, although this is also one of Dr. Montville’s research interests.  No, when I say food security, I mean it in the original sense, "availability of food and one's access to it".

    Tom, you see, has managed to combine two of his passions: food, and riding his bicycle.  He is currently riding his bicycle across the county (west coast to east coast) to raise funds for Elijah's Promise, which began as a small soup kitchen and has since become a multi-service agency that moves people out of poverty.

    And (here’s the intersection) he's about to pass within 30 miles of Manhattan, Kansas!

    I find his efforts very inspiring, and I hope you will too.  Check out his blog to learn more.

    Gus the dog is anything but a beauty queen, but on Saturday he won a contest for his looks.  The World’s Ugliest Dog of 2008 is a three-legged, one eyed, Chinese crested dog, named Gus.  The Chinese crested dog is a popular breed in the contest; in fact eleven of the seventeen contestants for this year are of this breed.  (See all there pictures here)

    The World's Ugliest Dog contest has taken place each year in Petaluma, California since 1976, and each year many people gather to look at faces of dogs that only a mother could love.  It’s kind of like a bad car wreck, these dogs are so disgustingly ugly, but you can’t look away.

    There are numerous sites on the web that showcase photos of the cutest, cuddliest pets.  So why do people care about the ugly ones?  I suppose that just as beauty is celebrated throughout the media, it would be only fair to display the ugliness as well.  Many magazines at the checkout line in the grocery stores have photos of celebrities on the red carpet in all their glory, and they also have photos of celebrities looking their worst, without any makeup or fancy clothes.

    American culture will continue to celebrate the cutest of the cute pets, but there will always be a special place in our hearts for those truly ugly dogs.

    With four daughters, I’ve changed a lot of diapers over the years.

    Almost all the diapers were cloth; at least for the first two children. Then, after too many green apple splatters seeping through, migrated to the seemingly more absorbent disposable diaper.

    And then there were the emergency dumps that, well, we’ve all had, regardless of age. On Weeds last night, Nancy Botwin, played by Mary Louise Parker (right), peed into a cup while waiting to cross the Mexican-U.S. border.

    Sometimes it’s not nearly that neat.

    A reader told The Consumerist yesterday that,

    "Last night we were out with friends and went to the Rocky Mountain Chocolate Factory at Bella Terra/Huntington Beach. We were eating outside as my 5 year old daughter got an uncontrollable urge to use the bathroom and began crying and screaming 'diarrhea, diarrhea.' I ran into the store with her in my arms, begging to use the bathroom and they refused multiple times.

    “I explained she had diarrhea and couldn't hold it and told them she was about to go on the floor. They refused again and never offered me any alternatives. I begged them to have a heart and that she was 5 but by that time she had lost it all over herself and me. I ran with her in my arms to the movie theater that let me use their bathroom. I cleaned her up, threw out some of her clothes and went back to the Chocolate Factory - asking for names and number of management. I again pleaded with them to use their heart in situations like this.”

    Almost a year ago, a similar incident happened at a Jo-Ann Fabrics in Indiana. With similar results.

    Today, California’s Orange County Register reported that officials with Rocky Mountain Chocolate Factory issued an apology, and that the story sparked a backlash that led to death threats, according to store owner, Bonnie Overturf, who was not there during the incident last Thursday.

    Overturf said her employees were following insurance policies for her store, and there were at least a dozen restrooms near the store the mother could have used.

    Bryan Merryman, chief operating officer for the Colorado-based candy company, issued an apology to the mother Tuesday, saying "the actions of one franchised store's employees do not represent the values of the company … We truly regret this situation occurred."

    "We are a very family friendly company and would never encourage any policy that does not take individual facts and circumstances into account,'' he wrote.

    Overturf, who said she apologized to the mother earlier, contacted police once death threats began and her home address was posted on an unknown Website. People also threatened to throw feces at her home, she said.


    People shouldn’t throw piles of shit at store owners and their homes; or leave burning bags of poop on the front step. Poop is the source of many pathogens, stores are not all equipped to handle public poop, and some people don’t clean up after themselves (or pick up their dog’s shit).


    But when kids (or others) gotta go, it’s better to isolate the mess to a bathroom.

    I’ve cleaned up lots of shit. And expect lots more.

    The Guernsey Press – of the Guernsey Islands – reports that an outbreak of salmonella, blamed on raw eggs used in mayonnaise, has left 18 customers and staff at an unamed island catering establishment needing treatment.

    Environmental health inspectors visited the premises last week and a spokesman said the infection had been contained.

    The spokesman would not confirm the location of the outbreak as he said the premises had been deemed fit to continue catering.

    Sounds surprisingly similar to an outbreak in Tasmania earlier this year,

    Tasmanian Director of Public Health, Dr Roscoe Taylor, said at the time that given the national increase, and the local experience of salmonella outbreaks associated with eggs, his department was proposing to introduce new measures to control the safety of raw egg products in Tasmania as a matter of urgency.

    Most would shy away from fugu, or puffer fish, but the Japanese love it. The internal organs and skin of the puffer fish contain a deadly poison called tetradotoxin, which causes paralysis of the diaphragm and death due to respiratory failure. It must be prepared by licensed cooks in order to remove the poisonous areas. Though it’s a dangerous meal, it’s been eaten for centuries.

    It’s not just that one-in-one thousand fish are poisonous; each fish comes packed with a dose of death if not properly prepared. Statistics from the Tokyo Bureau of Social Welfare and Public Health indicate 20-44 incidents of fugu poisoning per year between 1996 and 2006 in the entire country, leading to 34-64 hospitalizations and 0-6 deaths per year, for an average fatality rate of 6.8%

    Not only is it deadly, but fugu is costly. Most people consider it to have a weak taste, but Japanese gourmets will disagree. Chefs spend 7 to 8 years training in order to be certified to serve this treat.

    An outbreak of E.coli in spinach or Salmonella in tomatoes leads to national recalls and mass consumer aversion as products and produce become stigmatized. Yet a fish that is positively poisonous is still sought out in countries like Japan and Taiwan. There is some speculation as to how popular fugu would be if it was known to be completely safe. Would there be a sharp decrease in demand for the dish, or would it continue to be a special meal?

    The acceptance of fugu in Japanese culture is completely opposite of the Japanese attitude towards beef with BSE (bovine spongiform encephalopathy) commonly known as mad cow disease. Any meat that is at risk for containing traces of BSE is immediately removed from the food supply. What is the difference between dying from Creutzfeldt-Jakob disease, the human variant of BSE, and being poisoned by fish?

    Whether it’s the taste of the fish or the thrill of knowing it could be the last meal, I plan to stick to salmon instead.

    Since April, 613 persons infected with Salmonella Saintpaul with the same genetic fingerprint have been identified in 33 states and the District of Columbia. These were identified because clinical laboratories in all states send Salmonella strains from ill persons to their State public health laboratory for characterization.

    The marked increase in reported ill persons since the last update is not thought to be due to a large number of new infections. The number of reported ill persons increased mainly because some states improved surveillance for Salmonella in response to this outbreak and because laboratory identification of many previously submitted strains was completed. In particular, one new state, Massachusetts reported ill persons.

    The number of ill persons identified in each state is as follows: Arkansas (3 persons), Arizona (34), California (8), Colorado (4), Connecticut (4), Florida (1), Georgia (14), Idaho (3), Illinois (45), Indiana (9), Kansas (9), Kentucky (1), Maryland (18), Massachusetts (12), Michigan (4), Missouri (12), New Hampshire (1), New Jersey (1), New Mexico (79), New York (18), North Carolina (1), Ohio (3), Oklahoma (17), Oregon (5), Pennsylvania (5), Rhode Island (2), Tennessee (4), Texas (265), Utah (2), Virginia (21), Vermont (1), Washington (1), Wisconsin (5), and the District of Columbia (1). Among the 316 persons with information available, illnesses began between April 10 and June 13, 2008. Patients range in age from <1 to 99 years; 50% are female. At least 69 persons were hospitalized. No deaths have been officially attributed to this outbreak. However, a man in his sixties who died in Texas from cancer had an infection with the outbreak strain of Salmonella Saintpaul at the time of his death. The infection may have contributed to his death.

    Amy and I were at the expecting-a-baby doctor today, and I started telling her about yet another take on the my-tomatoes-are-safe-cause-they’re-local-so-buy-them story from Tennessee.

    Some locals farmers told Volunteer TV they,

    “… even use fertilizer that comes from the ground rather than a store. Their fertilizers are made up of layers of manure, weeds and hay.

    "It helps in killing off the bad bacteria. The worms are working through, turning it into the pure soils all around. The composting happens naturally."


    Such statements really need to be verified through microbial testing.

    Another farmer said,

    "The guinea come through and we let them. They'll walk through the garden and they don't eat any of the vegetables, they just eat bugs."


    The woman beside us in the doctor waiting room said her father used to have guineas in their garden and it worked real well for bug control.

    I pointed out the guineas were also Salmonella factories and would be increasing the dangerous bug load in the gardens growing that fresh produce.

    She said they used to have chickens at her farm, but got rid of them cause she got tired of the mess – the poop mess. Then we talked tornadoes.

    But lots of others are still talking tomatoes.

    Jeff Wilson, Mississippi State University Extension Service, told local media that, “locally grown tomatoes are most likely safe,” but didn’t say why. Maybe he was misquoted.

    Meanwhile, I got to make more friends by telling Forbes that washing off produce is a good precaution, but won't necessarily safeguard you from a foodborne illness, nor will only buying locally grown fruits and vegetables from the farmers' market,

    “At the farm level, produce can be contaminated in a variety of ways, including contact with untreated manure, infected or polluted water, workers with poor hygiene habits or unclean storage or transportation facilities, Powell says. While local farms may use less transportation and fewer workers, the chances for contamination are still there. And since fresh produce is, of course, uncooked, anything that comes into contact with it can taint it. Once E. coli or Salmonella gets inside a leafy green, tomato or sprout, it's hard to get rid of it.”

    The Boston Globe reports that inspectors found recently that a restaurant at the home of the Inspectional Services Division at 1010 Massachusetts Ave., as well as a cafe in City Hall that has been visited by the mayor, violated some of the most serious public health codes.

    Cafe 1010, located on the first floor of the Mass Ave. building, flunked inspections earlier this month and in December by failing to keep hot foods at 140 degrees or warmer and cold foods at 40 degrees or cooler. Both violations are considered critical because they could cause food poisoning. They had been corrected when inspectors followed up last week.

    Boston food safety consultant Lisa Berger said,

    "You would think it would be a deterrent that they're right in the middle of the city offices, but it's clearly not for some places. Everybody knows they get inspected by the health department, yet why do places get in trouble? It's amazing to me how some of them can't quite grasp the seriousness of it sometimes, even with the threat of closure."

    City Council member John Tobin suggested using a grading system for restaurants.

    "It's kind of like a scarlet letter. If your place is clean and up to code you have nothing to worry about. You've got people going in and eating, and people can get really sick if they're eating in a place infested with rodents or people aren't washing their hands or going by basic procedures to keep food fresh and the condition sanitary."

    For the past 10 years, when someone asks me, what can I do avoid Salmonella in tomatoes, or E. coli in spinach, especially if you – Powell – tell me I can’t wash it off, what am I supposed to do?

    I would sheepishly say, ask questions. Big grocers; local markets; they should be able to explain what they do to reduce microbial risks.

    But it’s not so easy. I’ve asked questions for years, and only rarely have received adequate responses. Most are of the it’s-local-it’s-safe or trust-me genre of food pornography, and, like most pornography, it’s fun to watch for awhile but gets really boring.

    Chris, a student who works with me at Kansas State, went to the student union the other day and ordered a bean and cheese burrito.

    “They slapped some pico de gallo on there for me. The previous day they had a sign that said they weren't serving due to Salmonella tomatoes.

    “I took it back and asked what made them start serving fresh tomatoes again. Not one of the 4 employees spoke English. All they would say is ‘yes, tomatoes.’”


    Buying any sort of fresh produce is an act of faith. I say, cut the BS and start deliberately marketing food safety. That way, someone has to back it up; not some dance with an auditor or certifier, or some other third party that has nothing to do with credibility and everything to do with providing distance when the shit hits the fan – or the produce.

    Otherwise, more hucksterism, and more of CNN’s Lou Dobbs.

    Andrew Schneider??? of the Seattle P-I, writes in a decent raw milk piece  this morning that consumers almost always link arms with government public health agencies banning the sale of food believed to contain dangerous pathogens. But that spirit appears to vaporize when the consumable is raw milk. Below are some excerpts:

    “Although the number of cases nationwide is low, contaminated raw milk can contain a strain of E. coli that sometimes causes hemolytic uremic syndrome, a life-threatening complication that can cause kidney failure and death.

    It took a 2005 outbreak of E. coli in raw milk that sickened 18 people in Washington and Oregon and put two children on life support to get all the players -- the dairy and raw milk communities, lawmakers, the state agriculture and health departments -- together to try to figure out what to do, Gordon said.

    Last week, the owners of the dairy that sold the tainted milk, Michael and Anita Puckett, pleaded guilty in federal court in Seattle to the charge of distributing adulterated food.

    Claudia Coles, food safety manager for the state Department of Agriculture, agreed that something had to done, that "in these outbreaks, it is almost always the children that become the victims."

    The state's options for trying to control the sale of raw milk products were limited. In other states where it was banned completely, a black market flourished. So the question facing regulators is whether public health is better protected by regulating, testing, licensing and inspecting the raw milk or just by banning it so it goes underground with no oversight.

    Doug Powell says he's not surprised that government health officials denounce the dangers of raw milk then turn around and license the sale of the same milk.

    "In part, it's because of the almost evangelical way people talk about raw milk and that America is founded on consumer choice," said the associate professor of food safety at Kansas State University.

    "The numbers of illnesses from outbreaks caused by unpasteurized milk are not that high. You could very easily make the cases that 'Wow, maybe tomatoes should be regulated a whole lot more than we do now because the numbers of cases of salmonella saintpaul are up to 550 now,' " said Powell, who is also scientific director for the International Food Safety Network.

    "I don't care if people drink raw milk. What I'm particularly concerned about is them then imposing their choice on their kids, because they're the ones who get sick. People have the right to sell a product, but if it makes people sick, they have a right to sue."

    Seattle food safety lawyer Bill Marler is up to his neck in many of those lawsuits. He grew up drinking raw milk on the farm "because that's what my dad wanted us to do," he said. He has tried injury suits stemming from most of Washington's raw milk outbreaks and is now handling similar cases in California and Missouri.

    "The entire raw milk debate is so emotionally charged that there's no common ground at all," Marler said. "The reality is if you poison a little child by selling a product that could easily be pasteurized, you're going to have to deal with the legal issues surrounding that," he said.

    Five people who got sick from salmonella this month ate at the same McDowell County restaurant, O'Dear's Country Diner on U.S. 221 in Marion, North Carolina, but the cases do not appear linked to the ongoing Salmonella-in-tomatoes outbreak.

    The restaurant was voluntarily closed Thursday, cleaned Saturday under the supervision of health department specialists, and plans to reopen Monday.

    Marion restaurant owner Bob Gaddy said he had not heard about the salmonella problems. He and his brother, Mack, have run Harvest Drive-In for 35 years. Like O'Dear, Gaddy makes a point of buying tomatoes and produce from somewhere he thinks is safe, but said it's tough to know.

    "You ask. But you also hope and pray.”

    When Amy and I were in Guelph, Ontario a few weeks ago, she aksed, “what’s with all the dandelions.”

    I tried to explain how municipalities, and now the province of Ontario, were proposing bans on the so-called cosmetic use of pesticides, even if the use of such chemicals had been declared safe by scientists working for the federal government.

    I have no intention of getting wound up in the pros, cons or otherwise of chemical use. But what has been absent in the public discussion of various risks is the voice of the government regulator, which can lead to the creation of an information vacuum, which can lead to all kinds of erroneous information amplified through various social media. It’s a well-documented phenomena, and I co-authored a 1997 book about it, Mad Cows and Mother’s Milk.

    So it was an unexpected surprise when Richard Aucoin, acting executive director of Health Canada’s Pest Management Regulatory Agency, penned a lucid, articulate, and well-thought out letter which appeared in the Ottawa Citizen.

    “Health Canada's priorities are the health and safety of Canadians and their food supply, and this primary mandate is applied when approving pesticides for use in Canada.

    Under the Pest Control Products Act, if a pesticide (herbicide, insecticide, fungicide) meets our stringent health and environmental safety standards and proves value in its application, it must be approved for use. Only those products that meet Canada's strict health and safety standards are registered for sale and use in Canada.

    When determining if a pesticide can be used in Canada, Health Canada conducts extensive health and environmental scientific reviews.

    Testing methods must have adhered to accepted international standards. The evaluation takes into account the available scientific information on potential health and environmental effects from publicly available studies including epidemiological and incident reports both nationally and internationally.

    Health Canada employs over 300 qualified scientists dedicated to the evaluation of pesticides, many of whom have doctorates and masters credentials in the fields of human health sciences, environmental and agricultural sciences. This team carefully scrutinizes the scientific information available on all of the components of a product, including both the active and non-active ingredients.

    In addition, before Health Canada makes a final decision on whether to allow the use of a pesticide, the Canadian public is invited to submit comments and questions.

    All chemical substances have inherent risks, which is why Health Canada has a dedicated regulatory program in place to review pesticides.

    Given the rigour of the evaluation process, we are confident that the pesticides approved for use in Canada, including lawn and garden products, can be used safely under the prescribed circumstances indicated on the label.

    Canadians should use pesticides judiciously, carefully follow label directions, and take measures to become better informed about their safe and effective use.
    Any questions about pesticides can be addressed to Health Canada's Pesticide Information Services at 1-800-267-6315.”

    It's 4 a.m. on a Sunday morning, the thunder and trains both sound like they're in my living room, and I'm talking about Salmonella and tomatoes on Chicago's WGN News Talk Radio 720.

    I'll review the mp3 file when the producer sends it along and see if I said anything silly. I try to keep the unsubstantiated food safety statements to a minimum. But, while providing company for truck drivers, insomniacs and conspiracy theorists, who knows what will slip out (doing Coast-to-Coat AM radio from 1 - 2 a.m on June 10 was actually a lot of fun).

    Ken Givens, commissioner of the Tennessee Department of Agriculture, wrote in a particularly lucid article in The Tennessean yesterday,

    "Our agency alone licenses and inspects more than 9,200 retail food establishments, 900 food manufacturers and 475 food warehouses for sanitation and proper food storage and handling. ... Food safety starts at the farm. In association with the UT Institute of Agriculture, we're launching a new initiative aimed at helping fruit and vegetable growers and distributors institute good agricultural practices, such as using safe sources of irrigation in the field and proper washing and handling after harvesting. "

    But then, Commissioner Givens joins our safest-food-in-the-world list, by stating,

    "America still has the safest, most affordable and abundant food supply in the world."

    Not to be outdone, Carol B. Dover, President/CEO, Florida Restaurant & Lodging Association, Tallahasse, writes in yesterday's Orlando Sentinel that,

    "… according to Florida Department of Health statistics, less than half of reported foodborne illness cases are attributable to restaurants. While it is easy to blame the last restaurant visited, the source is very likely improperly prepared home-cooked food."

    It is very likely that Carol Dover can't back that statement up. It's easy to blame consumers, but there are too many outbreaks that are simply beyond a consumer's control. Sorta like Salmonella and tomatoes.

    And for no particular reason, this is a picture Bill Marler sent me of a butcher's shop in Wales. Reminds me of last year in France and the rampant cross-contamination Amy and I witnessed at our local butcher in the beach town of Maubuisson.

    Since April, 552 persons infected with Salmonella Saintpaul with the same genetic fingerprint have been identified in 32 states and the District of Columbia. These were identified because clinical laboratories in all states send Salmonella strains from ill persons to their State public health laboratory for characterization. The marked increase in reported ill persons since the last update is not thought to be due to a large number of new infections. The number of reported ill persons increased mainly because some states improved surveillance for Salmonella in response to this outbreak and because laboratory identification of many previously submitted strains was completed. In particular, the number of ill persons reported from Texas markedly increased, and two new states, New Jersey and Rhode Island, reported ill persons.

    FDA recommends that U.S. retail outlets, restaurants, and food service operators offer only fresh and fresh cut red plum, red Roma, and round red tomatoes and food products made from these tomatoes from specific sources listed at: http://www.fda.gov/oc/opacom/hottopics/tomatoes.html#retailers*. Cherry tomatoes, grape tomatoes, and tomatoes sold with the vine still attached from any source may be offered.

    Outbreaks involving fresh produce do happen in other countries -- they're just not so well reported.

    Soderstrom et al. do a nice job in the current Foodborne Pathogens and Disease describing a 2005 outbreak of E. coli O157 in Sweden.

    "A total of 135 cases were recorded, including 11 cases of hemolytic uremic syndrome. The epidemiological investigations implicated lettuce as the most likely source of the outbreak, with an OR of 13.0 (CI 2.94–57.5) in the case–control study. The lettuce was irrigated by water from a small stream, and water samples were positive for Stx 2 by PCR. The identical VTEC O157 Stx 2 positive strain was isolated from the cases and in cattle at a farm upstream from the irrigation point."

    Watch that irrigation water.

    Michelle just returned from two weeks in Japan. I asked her to take some pictures of Japanese hand washing facilities and the like. In her own words,

    "I'm a bit embarrassed at how many pictures I took during the trip.  At first my group members made fun of me taking photos of bathrooms, but by the end of the trip they would walk out of the bathroom saying "Cool, Michelle, you've got to go in and take a picture of that awesome bathroom!"

    CDC is collaborating with public health officials in many states, the Indian Health Service, and the U.S. Food and Drug Administration (FDA) to investigate an ongoing multi-state outbreak of human Salmonella serotype Saintpaul infections.

    An epidemiologic investigation comparing foods eaten by ill and well persons has identified consumption of raw tomatoes as the likely source of the illnesses. The specific type and source of tomatoes is under investigation; however, the data suggest that illnesses are linked to consumption of raw red plum, red Roma, or round red tomatoes, or any combination of these types of tomatoes, and to products containing these raw tomatoes.

    Since April, 383 persons infected with Salmonella Saintpaul with the same genetic fingerprint have been identified in 30 states and the District of Columbia: Arkansas (2 persons), Arizona (26), California (8), Colorado (2), Connecticut (2), Florida (1), Georgia (8), Idaho (3), Illinois (34), Indiana (8), Kansas (9), Kentucky (1), Maryland (10), Michigan (3), Missouri (9), New Hampshire (1), New Mexico (70), New York (9), North Carolina (1), Ohio (3), Oklahoma (5), Oregon (4), Pennsylvania (2), Tennessee (4), Texas (131), Utah (2), Virginia (17), Vermont (1), Washington (1), Wisconsin (5), and the District of Columbia (1). These were identified because clinical laboratories in all states send Salmonella strains from ill persons to their State public health laboratory for characterization. The marked increase in reported ill persons is not primarily due to a large number of new infections. The number of reported ill persons increased markedly mainly because some states improved surveillance for Salmonella in response to this outbreak and because laboratory identification of many previously submitted strains was completed.

    Among the 243 persons with information available, illnesses began between April 10 and June 5, 2008. Patients range in age from <1 to 88 years; 47% are female. At least 48 persons were hospitalized. No deaths have been officially attributed to this outbreak. However, a man in his sixties who died in Texas from cancer had an infection with the outbreak strain of Salmonella Saintpaul at the time of his death. The infection may have contributed to his death.

    Only 3 persons infected with this strain of Salmonella Saintpaul were identified in the country during the same period in 2007. The previous rarity of this strain and the distribution of illnesses in all U.S. regions suggest that the implicated tomatoes are distributed throughout much of the country. Because of inherent delays in reporting and because many persons with Salmonella illness do not have a stool specimen tested, it is likely many more illnesses have occurred than those reported.

    I'm gonna drop the Food Safety Network name.

    Just doesn't seem to fit anymore.

    Too many hacks and posers.

    I started sending out news shortly after I began my PhD in 1993. Jack-in-the-Box had just happened, Al Gore hadn't invented the Internet yet, but I was plugged in through the various twists and turns of life, and started sharing stories -- in real time --  with my science-geek colleagues.

    They seemed to like it, and research confirmed it was useful.

    In 1993, food safety types were conditioned to reading about outbreak investigations when CDC's MMWR arrived in the mail six months later. That's still way faster than the Canadian government types write up any outbreak investigation.

    I originally called the news distribution the Food Safety Network cause network was sorta new. Sure, it seems dated now, but at the time, we rocked. Now, it just rolls.

    The whole idea of calling my lab the Food Safety Network rests with Lester Crawford. I wanted to create a group modeling Georgetown University's Center for Food and Nutrition Policy (which has since moved). Lester spent a couple of days in Guelph, and told me, whatever you do, make it bigger than yourself. No one cares about Doug Powell's lab. So give it a name. And bring in others.

    So I did.

    Unfortunately, due largely to my unfailing optimism, others went for the short game. In the spirit of open and honest collaboration, the University of Guelph went and trademarked Food Safety Network in Canada the day I resigned -- and didn't bother to tell anybody. Then they scooped up whatever money was left to cover the deficit in their paper clip fund.

    The actions of so many have been small and petty. But there have always been a few that make it worthwhile.

    Katija Blaine and Ben Chapman have both been with me in various capacities since 1999. Still are. We've traveled the various minefields of genetically engineered sweet corn and on-farm food safety programs for fresh produce, and now we're all having babies.

    Katija was first up on Saturday, delivering Cormac (right). Congrats to Katija and Jeff.

    Ben and Dani and due in Sept.

    And me -- forever trying to hang out with the cool kids -- me and Amy are due the end of November.

    Got no time for posers.

    Amy and I are back in Manhattan. We missed a hailstorm, the first tornado in 42 years, but we didn't miss Salmonella in tomatoes.

    We left Quebec City at 9 a.m. last Friday. National Public Radio Science Friday wanted me as a guest, and so did CNN. By 3:30 pm, we were in nowhere southwestern Ontario and I had to call the NPR studio -- and they insisted on a landline.

    So, after several pay phones didn't work out, we found a lakeside motel. I hastily pleaded with the innkeeper for her phone. She said, "What's it worth to you?"

    I gave her $20.

    That's me doing my live interview on NPR (above, not exactly as shown; left, exactly as shown).

    A couple of hours later we arrived at a TV studio in Toronto for a CNN interview. They said I was too late for Friday's show, but they wanted the footage anyway and maybe they'd use it Monday.

    They didn't.

    I've done dozens of radio interviews, and find myself defending public health types -- why is it taking so long to find the source of Salmonella in tomatoes? What tomatoes should be avoided? I explain, but even through radio, can sense the listeners eyes glazing over. Public health has always been a largely thankless job  -- whether local, state or federal.

    So a big thank you to Elizabeth Weise of USA Today, whose story in this morning's paper is an outstanding exposé of how the Salmonella in tomato case was cracked. It has become required reading in any of my courses.

    To all the armchair quarterbacks that fill talk radio and Internet blogs, stop bitching and start producing. And move out of your parents' basement.

    Mayra Rivarola is a new student in my lab and pulled together a decent piece on tomatoes and salmonella. And provided some excellent tomato photos.

    Karen Wisser of Eastside & Westside markets in Manhatan, Kansas, knows fresh produce. Wisser says buying produce from her markets is much safer than buying produce from larger retailers because she can identify their supplier easily and go back directly to the source in case of an outbreak of foodborne illness.

    "If we don’t like what we’re getting, we can stop buying from them, we know what consumers want,” said Wisser.

    Bryant Ambelang, chief marketing officer of Desert Glory, one of North America’s largest grower of greenhouse tomatoes, says that food safety is a top priority which is why the company invests in greenhouse operations, private wells, continual testing procedures and 100% product traceability.

    The latest outbreak of salmonella associated with fresh tomatoes, with 277 sick people now identified in 28 states, including Kansas, raises questions about the safety of fresh produce and the food supply in general.

    The U.S. Food and Drug Administration is advising consumers to stay away from red plum, red roma and round red tomatoes unless they come from areas that have been given the all-clear by the FDA. The list is available at www.fda.gov/oc/opacom/hottopics/tomatoes.html#retailers. The FDA website also states that homegrown tomatoes are safe to consume.

    But, should consumers blindly assume that a tomato, because it was bought from the farmer next door, is free of salmonella or other dangerous bugs?

    To protect the produce, it is essential that safety guidelines are followed, beginning on the farm.

    Fresh fruits and vegetables can be contaminated through different venues including: contact with untreated manure, contaminated water, workers with poor hygiene habits or infected with contagious diseases, unclean containers, tools, storage or transportation facilities.

    I started worked with Ontario Greenhouse Vegetable Growers in 1998. The general manager at the time, Denton Hoffman, saw the U.S. export market growing rapidly, and told me of his recurring nightmare … one he wanted to prevent.

    "The phone rings and it's a retailer on the U.S. east coast. He says he's got a customer who says she got sick from eating my Ontario greenhouse tomatoes. What do I say?"

    That was the challenge Denton laid out for my group in 1998. Using a risk analysis approach, we assessed the risks for all 220 or so Ontario greenhouse producers, developed management schemes, and communicated what we were doing to buyers, consumers, whoever.

    We learned lots of things about building trust with individual growers (which means visiting their farms, not plopping them in a classroom and trying to make them HACCP experts), coming up with practical, farm-based solutions, and being on call 24/7 for when those phone calls come in (that's me and Amber Leudtke, back in about 2001, in a greenhouse, above right).

    But I could never get the group to take the final step and really promote their food safety program. I suggested putting a url on the stickers at retail that would link to a series of videos showing whoever wanted to see them the food safety practices undertaken by the growers.

    During the latest Salmonella-in-tomatoes outbreak, a rep for Nature Sweet, a grower in San Antonio e-mailed me and said, what should we do? This grower does great things for food safety. So I told her.

    The rep wrote me back last week and said,

    "I spoke with you last week briefly about the tomato outbreak.  You made the suggestion about putting our company's safety practices on blogs, YouTube, etc.  Well, we took your advice and have created a video that is up on YouTube.  Here is the link to the video if you're interested to view it, http://www.youtube.com/naturesweettomatoes."


    The video is also below. Sure, I'd rather see a farmer than the marketing dude, and the intro will have to be redone for future use, but the rest is great.

    And they spelled it out in a press release:

    Our greenhouse growing practices are the foundation of our food safety program:

    • The water supply used in our greenhouses is self-contained, filtered, and secure. Water from each well and each greenhouse farm is continuously monitored and tested for purity by our staff and by third party experts.
     
    • We use only natural fertilizers.

    • Our tomatoes are picked under sanitary conditions.

    • Food safety begins with the seed. Our tomato seeds are always naturally selected, disinfected and germinated under sanitary conditions.

    • Within each greenhouse, we control and monitor all intakes – water, nutrients, and pest control.

    In addition to our greenhouse practices, we also employ the following food safety initiatives:

    • Regulate all aspects of tomato production and processing, as well as employ the best agricultural practices.

    • Monitor all of our systems continuously to ensure that our produce exceeds the highest food safety standards and FDA guidelines. In addition to our adherence to HACCP-based safety practices, we follow rigorous training, growing, packing, and shipping standards.

    • Use a food safety coding system that provides us with traceability of every case and pallet of tomatoes to the greenhouse in which they are grown. In addition, each individual selling unit has a comprehensive food safety tracking code.

    • Test, monitor, and audit our products, our water, our processes, and our procedures regularly with staff and third-party experts.


    I can quibble about details. But it's a great start, and, like transparency in risk assessments, now that it's out there, it can be improved. It's a lot better than just telling consumers to wash their tomatoes or it's local so it's safe.

    Three-year-old Brianna Kriefall and her family ate at a Sizzler restaurant in South Milwaukee in July 2000. Brianna died a week later after battling E. coli-related hemolytic uremic syndrome.

    Brianna, along with most of the other 140 people who were sickened in the outbreak, consumed watermelon that had been cross-contaminated with raw meat.

    Genetic testing showed the microbes that made the restaurant patrons sick matched microbes contained in an unopened package of meat.

    The national Sizzler chain, its local franchise and an insurance company are suing Excel Corp., the subsidiary of Cargill Inc. that produced the meat.

    On Friday Brianna's family reached a $13.5 million settlement with the company's meat supplier and others.

    The Kriefalls' case had been dismissed in 2004 by a different Milwaukee County Circuit judge after Excel lawyers argued the company was exempt from state lawsuits because it had followed federal regulations in handling the beef sold to Sizzler.

    An appeals court reversed the dismissal, saying the legal action fit within the federal goal of making food safer for consumers. The U.S. Supreme Court declined Excel's appeal.

    There's been lots of silly statements in the latest Salmonella-in-tomato outbreak. For example, at right is the sign from The Pad in Topeka, Kansas (photo by Stephanie Maurer). I have no idea which Dept. of Ag. inspected the tomatoes, and I'm not sure what they thought they'd find by looking. I'll be revisiting the risk communication highlights in the coming weeks.

    One press release stood out yesterday. Health Canada decided to "remind Canadians of the importance of proper handling and preparation of fresh tomatoes in order to prevent foodborne illness."

    Uh-oh. Sure washing can remove some amount of pathogens and dust, but not much. As Robert Tauxe, Deputy Director, Centers for Disease Control Division of Foodborne, Bacterial, and Mycotic Diseases, pointed out at a session sponsored by the New York Academy Of Sciences in April, "Washing might be logical, but it turns out that it removes very few pathogens."

    Reminds me of past outbreaks when various groups have tried to advise consumers to control problems that were quite out of their control -- like Salmonella in tomatoes (see, pathogens in produce; once inside they ain't being washed off at all).

    The Health Canada effort concludes by stating

    "... there are as many as 13 million cases of food-related illnesses in Canada every year. Many of these illnesses could be prevented by following proper food handling and preparation techniques."

    Why do the PR thingies feel it necessary to add on such a meaningless statement about proper handling and preparation in an outbreak that does not appear to involve food handling and preparation? Food safety for produce begins on the farm, and then all the way through the farm-to-fork system. But especially, for fresh produce, on the farm. Canadian taxpayers deserve better.

    Bill Marler's going to London, and if he gets to Wales, beware the Cardiff takeaway.

    The South Wales Echo reports that cockroaches, dirt, poor personal hygiene and congealed fat are just some of the shocking  details uncovered in health inspector reports on kebab shops and chippies in Caroline Street.

    Hundreds of hungry revellers regularly use the street, widely known as Chip Alley (below), after nights out on the town.

    But the most recent kitchen hygiene inspection reports, obtained under the Freedom of Information Act, show the street’s takeaways broke food safety regulations more than 70 times.

    The number of people sick from salmonella-tainted tomatoes jumped to 228 in 23 states Thursday as the government learned of five dozen previously unknown cases and said it is possible the food poisoning contributed to a cancer patient's death.

    Twenty-five people have been hospitalized as a result of the U.S. outbreak, which has been linked to raw plum, Roma and round tomatoes.

    The Food and Drug Administration has not pinpointed the source of the outbreak. With the latest known illness striking on June 1, officials also are not sure if all the tainted tomatoes are off the market.

    The FDA's food safety chief, Dr. David Acheson, said,

    "As long as we are continuing to see new cases come on board, it is a concern that there are still contaminated tomatoes out there."

    The FDA is directing consumers to its Web site — http://www.fda.gov — for updated lists of the safe regions.

    Also safe are grape tomatoes, cherry tomatoes and tomatoes sold with the vine still attached. That is not because there is anything biologically safer about those with a vine but because the sick have assured investigators that is not the kind of tomato they ate.

    What if you did not go to the store armed with a list, or the store or restaurant manager cannot assure that any plum, Roma or round tomatoes came from safe regions?

    "If you don't know, don't take the risk," Acheson said.

    Cooking also kills salmonella, but the FDA is not formally advising people to cook suspect tomatoes for fear they will not get them heated thoroughly.

    (The possibility also exists for cross-contamination during preparation -- dp).

    Meanwhile, export-quality tomatoes labeled "Ready to Eat" in English flooded Mexico City markets on Thursday after a salmonella scare in the U.S. stopped them from crossing the border.

    Associated Press reports that most consumers do not even know about the U.S. salmonella scare. And those who do, rarely care. Mexicans are accustomed to washing all produce because the vegetables sold on the national market are not held to the same standards as those certified for export.

    Sergio Martinez, a 40-year-old bricklayer, said, "What the U.S. doesn't want is what we see here. They always send the best stuff over there, from avocados to tequila. What ends up here is second-rate. Almost all vegetables are contaminated with something because they water them with sewer water and put on a lot of chemicals."

    Agriculture Secretary Alberto Cardenas told Televisa network Thursday, "The Mexican tomato is safer and cleaner than ever."

    Even U.S. officials agree that certified Mexican exporters are among the safest in the world. Their fields are irrigated with fresh water, and their packing plants are staffed by workers covered head-to-toe in sterile clothing. Inspectors monitor the process at every step.

    The U.S. Centers for Disease Control and Prevention report in the current issue of Morbidity and Mortality Weekly Report on Escherichia coli O157:H7 infections in children associated with raw milk and raw colostrum from cows -- California, 2006. Some highlights below:

    On September 18, 2006, the California Department of Public Health (CDPH) was notified of two children hospitalized with hemolytic uremic syndrome (HUS). One of the patients had culture-confirmed Escherichia coli O157:H7 infection, and both patients had consumed raw (unpasteurized) cow milk in the week before illness onset. Four additional cases of E. coli O157:H7 infection in children who had consumed raw cow milk or raw cow colostrum produced by the same dairy were identified during the following 3 weeks. In California, intrastate sale of raw milk and raw colostrum is legal and regulated. This report summarizes the investigation of these cases by CDPH, the California Department of Food and Agriculture (CDFA), and four local health departments and subsequent actions to prevent illnesses. As a result of this and other outbreaks, California enacted legislation (AB 1735), which took effect January 1, 2008, setting a limit of 10 coliforms/mL for raw milk sold to consumers. Raw milk in several forms, including colostrum, remains a vehicle of serious enteric infections, even if the sale of raw milk is regulated.

    Six cases were identified; four persons had culture-confirmed infections, one had a culture-confirmed infection and HUS, and one had HUS only. The median age of patients was 8 years (range: 6--18 years), and four of the patients (67%) were boys. The six cases identified during this investigation were geographically dispersed throughout California. All six patients reported bloody diarrhea; three (50%) were hospitalized. Illness onset occurred during September 6--24, 2006. Isolates from the five patients with culture-confirmed infections had indistinguishable pulsed-field gel electrophoresis (PFGE) patterns. The PFGE pattern was new to the PulseNet (the National Molecular Subtyping Network for Foodborne Disease) database and differed markedly from the pattern of the E. coli O157:H7 strain associated with a concurrent multistate outbreak linked to spinach consumption (1). Four of the five E. coli O157:H7 isolates were subtyped by multiple-locus variable-number tandem repeat analysis (MLVA) according to a protocol used by CDPH laboratory and were found to have closely related MLVA patterns (2).

    Five of six patients reported they had consumed brand A raw dairy products in the week before their illness onset; the sixth patient denied drinking brand A raw milk, although his family routinely purchased it. Among the five patients who consumed brand A dairy products, two consumed raw whole milk, two consumed raw skim milk, and one consumed raw chocolate-flavored colostrum. Four of the five patients routinely drank raw milk from dairy A. One patient was exposed to brand A dairy product only once; he was served raw chocolate colostrum as a snack when visiting a friend. No other food item was commonly consumed by all six patients. No other illness was reported among household members who consumed brand A dairy products.

    Using purchase information supplied by the patients' families, investigators determined that the patients consumed raw milk from lots produced at dairy A during September 3--13, 2006. Milk samples from these production dates were not available for testing. Fifty-six product samples from several lots with code dates of September 17, 2006, or later were retrieved from retails stores and dairy A and were tested for aerobic microflora, total coliform, fecal coliform, and E. coli O157:H7. The outbreak strain of E. coli O157:H7 was not found in any product samples. However, standard aerobic plate counts and coliform counts of collected samples with code dates of September 17 through October 9, 2006, were indicative of contamination. Colostrum samples had high standard plate counts and total coliform counts, and fecal coliform counts of 210--46,000 MPN/g. California standards limit standard plate counts for raw and pasteurized milk to 15,000 CFU/mL and total coliform counts for pasteurized milk to 10 coliform bacteria/mL. At the time of this outbreak, California did not have a coliform standard for milk sold raw to consumers. California also classifies colostrum as a dietary supplement, for which it has no microbiologic standards, rather than a milk product.

    Raw milk from dairy A was the likely vehicle of transmission, but the exact mode of milk contamination in this outbreak was not determined.

    Asymptomatic cows can harbor pathogens and cause human illness by shedding pathogens in untreated milk or milk products. These findings suggest that if raw milk had been subject to the same coliform standard as pasteurized milk in California, milk from dairy A might have been excluded from sale and this outbreak might have been averted.

    From 1998 to May 2005, raw milk or raw milk products have been implicated in 45 foodborne illness outbreaks in the United States, accounting for more than 1,000 cases of illness (CDC, unpublished data, 2007). Because illnesses associated with raw milk continue to occur, additional efforts are needed to educate consumers and dairy farmers about illnesses associated with raw milk and raw colostrum. To reduce the risk for E. coli O157 and other infections, consumers should not drink raw milk or raw milk products.

    During the 728 or so interviews I've done on tomatoes and Salmonella in the past week, a radio reporter in Calgary asked me, as did several other Canadian outlets,

    "What is the Canadian Food Inspection Agency doing?"

    "Nothing."

    CFIA can speak for itself.

    When asked if Canadians were safe from this outbreak, I said, maybe, depends on first figuring out where the contaminated tomatoes were grown, then depends on what was coming into Canada at that point in time.

    That uncertainty would help explain why Canadian fast-food outlets pulled fresh tomatoes from their offerings -- at least until the source could be verified.

    But, I added, even if someone did get sick, it would be difficult to notice because Canadian health surveillance sucks.

    Apparently the Canadian Medical Association agrees, calling the system,

    "a national embarrassment."

    Dr. Kumanan Wilson writes in the Canadian Medical Association Journal that the Auditor General of Canada has warned 3 times, most recently in May, 2008, that Canada's failure to develop surveillance systems puts Canadians at risk.

    In an accompanying editorial, Dr. Amir Attaran  of the University of Ottawa, writing on behalf of CMAJ's editorial team, calls upon the federal government to "legislate a way past the jurisdictional schisms" and make information regarding health epidemics readily available. Currently, "12 of 13 provinces are under no obligation to share information with the federal government or the rest of Canada during an outbreak," writes Dr. Attaran. "We at CMAJ believe this is a national embarrassment."

    I love Manhattan (Kansas).

    People are always asking me, with a bemused, smug look, Kansas? Why would you move to Kansas?

    I explain to them how Manhattan is huddled in the Flint Hills, beautiful spot, and most of the bad weather goes around Manhattan.

    Not last night.

    The townhouse Amy used to live in probably doesn't exist anymore. That was one of two areas of town that got hammered by a tornado about 11 pm Central time.

    ABC affiliate KTKA in Topeka captured the tornado on video as it entered Manhattan, at least until the camera on the weather tower got taken out (see below).

    Cheryl May, Kansas State University's (awesome) director of media relations extraordinaire, told CNN the storm destroyed a wind erosion lab, damaged several engineering and science buildings and tore the roof off a fraternity house at the school (right, Weber Hall, home of much of Animal Science).

    "Our campus is kind of a mess."

    There were no immediate reports of injuries, she said.

    In an update released at 8 a.m. (CST), Tom Rawson, vice president for administration and finance, estimated storm damage at Kansas State University to exceed $20 million.

    "The damage on campus is extensive. Roofs have been damaged or torn off, windows have been blown out in many buildings. Weber Hall is severely damaged. The Wind Erosion Lab is gone. There is significant damage to the engineering complex, and to Waters, Call, Cardwell and Ward Hall."

    And since my students don't seem to know, but of course read barfblog, classes are cancelled for today.

    Local radio station KMAN has a complete list of known damage. People are being asked to stay away from damaged areas -- and there are various unsubstantiated reports of looting.

    The U.S. Department of Agriculture has the following food safety advice after a weather emergency:

    Keep the refrigerator and freezer doors closed as much as possible to maintain the cold temperature.

    Discard refrigerated perishable food such as meat, poultry, fish, soft cheeses, milk, eggs, leftovers and deli items after 4 hours without power.

    Never taste a food to determine its safety

    Drink only bottled water if flooding has occurred

    Undamaged, commercially prepared foods in all-metal cans and retort pouches (for example, flexible, shelf-stable juice or seafood pouches) can be saved.

    When in Doubt, Throw it Out


    If you have any firsthand reports, pictures or video, send it along. Amy and I are going to start working our way home from Quebec City.

    Rebekah Denn of Seattlepi.com, a barfblog.com fan (see below), writes,

    With a tomato-related salmonella outbreak in 16 states, the Neighborhood Farmers Market Association got this interesting question:

    "Are tomatoes from the University District farmer's market safe to eat, given the FDA's recent warning about tomatoes & salmonella?"

    The F.D.A. has linked the nasty illness to raw red plum, red Roma and round red tomatoes. The feds say it's OK to eat those varieties if they're sourced from regions that are not associated with the outbreak, clearing tomatoes from places like California and Canada. Washington did not make the all-clear-as-far-as-we-know list.

    The market association is checking in with its greenhouse growers on the topic, and sent out this reply to the query:

    "Yes, our local farm tomatoes are definitely safe. The outbreak is likely due to the wide use of some kind of composting medium on big factory farms that was contaminated - but none of our market farmers are connected in any way to those kinds of operations. In fact, the tomatoes at the markets right now are all hothouse tomatoes, which makes them even safer, as they are grown in wood bark. Also, our farmers are mostly growing heirloom varieties, both in their hothouses and in their fields.

    The FDA Web site also notes that homegrown tomatoes are safe. Our market farmers are essentially growing homegrown tomatoes: they are not huge operations but rather smaller family farms, using safe, healthy and sustainable growing methods. These farmers live on their farms, pick the harvest themselves and eat the food they grow as well as selling it to local markets."

    I checked in with Doug Powell, associate professor and scientific director of the International Food Safety Network at Kansas State University -- but to me better known for "BarfBlog," an acerbic and opinionated and evidence-based blog on food safety.

    His take on the farmer's market go-ahead? Not so fast. He wrote:

    "Whether your produce comes from around the corner or around the globe, contamination must be prevented beginning on the farm. Ask your tomato supplier:

    -- What do you do for food safety?
    -- Do you or your suppliers test wash water for bacteria? Irrigation
    water?
    -- What soil amendments are being used?
    -- Do you or your suppliers train your staff on handwashing?"

    But wait! Aren't the farmer's markets at least safe from the current salmonella outbreak, I asked, if the farmers are truly growing different varieties than the ones identified with the problem?

    Powell said yes, although there's no basis (yet, I say) for the speculation that big factory farms caused the problem. In general, though, when it comes to food safety, "there is no evidence that sustainable and local is safer."

    But wouldn't outbreaks from small local farms at least be easier to contain and easier to track?

    Maybe, Powell wrote, but it's a tough comparison to make. "We have no sense how often they happen because they are small and don't get picked up."

    So, talk to the people who grow your produce. Ask them questions. The advantage of the farmer's markets is, at least at the markets you actually get that chance.


    Barfblog: the acerbic and opinionated and evidence-based blog on food safety. I like that.

    Here are my favs:

    "The misunderstood tomato"












    "Does a tomato have intestines?"











    "Dirty Salmonella is back to getcha"

    Julie Zawisza, a spokeswoman for the Food and Drug Administration, told The New York Times late Tuesday,

    "We are getting closer to identifying the source or sources."

    Dr. Patricia Griffin, the chief of the disease centers’ enteric disease epidemiology branch, was cited as saying no one knows whether food has gotten more dangerous or whether the growing number of outbreaks results from better surveillance, and that both may be true.

    The disease control agency has confirmed 167 salmonella cases in the current outbreak. But Dr. Griffin said the agency estimated that only 1 in 38 cases were ever reported to the authorities, so the problem was likely to be greater.


    Keith Warriner of the University of Guelph told New Scientist.com that pathogens like Salmonella have probably evolved to cope with life outside our intestines. Escherichia coli O157:H7 strain thrives on leafy greens such as spinach and lettuce, while Salmonella tends to do best on fleshier fruits and vegetables.

    The bacteria probably come from groundwater contaminated with animal faeces, he says. Once Salmonella gets on and into a tomato, the fruit acts like an incubator. Bacteria divide even in the cool temperatures of packing houses. "If you get a few samples into the internal tissue, then they will grow for sure," Warriner adds.

    Meanwhile, I've been to Toronto and back to Quebec City, with a flurry of media activity along the way. Canadian Broadcasting Corporation's The National caught up with me in Toronto and aired the story on the national news last night (upper, right). Unfortunately, my Kansas State hockey T-shirt logo was not included in the camera shot.

    Last night, from 1-2 a.m. EST, I was the guest on Coast to Coast with George Noory which is broadcast on some 500 AM radio stations across the U.S.. Besides the government and alien conspiracy explanations of how Salmonela gets in tomatoes, it was a lot of fun, and we covered a lot of the issues. If anyone out there heard the show, please pass on your constructive comments.

    This morning it was off to the CBC studios in Quebec City for an appearance on Newsworld. I proudly wore my barfblog T-shirt.









    And if you're a French professor or graduate student from Kansas and you're in Quebec, you have to  partake of the local food culture; that means poutine.

    I just wrapped up a food safety talk at the World Congress for Processing Tomatoes. Delegates from 34 countries have converged in Toronto for meetings, mirth and merriment. The Salmonella in fresh tomatoes outbreak was up for discussion, but these are the processing folks -- it's all cooked.

    This picture (right) was taken by in Cincinnati, Ohio, and posted on The Consumerist. Just weird.

    And The Packer says today in an editorial that the source, not criticism, should be the top priority in outbreak.

    Too vague. Too slow. Too aggressive.

    All of the above criticisms may apply to the handling of the recent linkage of Salmonella Saintpaul to tomatoes by the Food and Drug Administration and various federal and state agencies.

    Unfortunately, the criticisms are easy to level, but not so easy to apply in reality.
    The FDA was too specific in warning consumers in Texas and New Mexico to avoid round red and roma tomatoes. Shouldn’t consumers in other states receive the warning? On the other hand, the warning was too vague. Many cocktail-style tomatoes are round and red. Many greenhouse tomatoes are round and red yet not sold on the vine, but the FDA was saying it was OK for consumers to eat tomatoes on the vine from greenhouses.

    The New Mexico Department of Health was perhaps too aggressive June 4 in naming Mexico as the likely source of the product. At that time, the FDA stated it was impossible to say whether the tomatoes were domestic or imported.

    And because the foodborne illnesses occurred over so long a stretch, the tomatoes very likely did not come from one single grower. There is a possibility they were contaminated somewhere along the supply chain.

    Yet, despite the rush to a conclusion, there is legitimate criticism that parties have acted too slowly. This situation affects the entire tomato category. By extension, it affects products that are used with tomatoes, such as fresh basil and some salad items. A lot of people will lose a lot of money over this.
    In outbreaks that decimate a category, it’s absolutely imperative to say the right thing at the right time.

    There needs to be better coordination between state and national organizations. The overseeing parties must work closely with both the growing community and retailers to ensure that public comments do not unintentionally mislead consumers or create false perceptions.

    The utmost importance is finding the source. Until then, all handlers are presumed guilty and suffer the consequences of lower sales.

    Since mid-April, 167 persons infected with Salmonella Saintpaul with the same genetic fingerprint have been identified in 17 states: Arizona (12 persons), California (2), Colorado (1), Connecticut (1), Idaho (2), Illinois (27), Indiana (7), Kansas (5), Michigan (2), New Mexico (39), Oklahoma (3), Oregon (3), Texas (56), Utah (1), Virginia (2), Washington (1), and Wisconsin (3). These were identified because clinical laboratories in all states send Salmonella strains from ill persons to their State public health laboratory for characterization. Among the 73 persons who have been interviewed, illnesses began between April 16 and May 27, 2008. Patients range in age from 1 to 82 years; 49% are female. At least 23 persons were hospitalized. No deaths have been reported.

    At this time, FDA is advising U.S. consumers to limit their tomato consumption to those that are not the likely source of this outbreak. These include cherry tomatoes; grape tomatoes; tomatoes sold with the vine still attached; tomatoes grown at home; and raw red Roma, red plum, and round red tomatoes from specific sources listed at: http://www.fda.gov/oc/opacom/hottopics/tomatoes.html. Consumers should be aware that raw tomatoes are often used in the preparation of fresh salsa, guacamole, and pico de gallo, are part of fillings for tortillas, and are used in many other dishes.

    FDA recommends that U.S. retail outlets, restaurants, and food service operators offer only fresh and fresh cut red Roma, red plum, and round red tomatoes and food products made from these tomatoes from specific sources listed at: http://www.fda.gov/oc/opacom/hottopics/tomatoes.html#retailers. Cherry tomatoes, grape tomatoes, and tomatoes sold with the vine still attached from any source may be offered.

    The Los Angeles Times reports that fast-food chains Taco Bell Corp. and Chipotle Mexican Grill Inc. have, in addition to McDonald's and others, stopped serving certain tomatoes. Same with supermarket chains Ralphs, Vons and Albertsons, which stopped selling red plum, red Roma or round red tomatoes cited by the FDA.

    Elizabeth Weise of USA Today reported this morning that simply washing tomatoes can help, but it won't necessarily remove the salmonella bacteria, because when tomatoes are picked on very hot days and put into cold water to chill, salmonella on their surface can be drawn up into the fruit.

    David Acheson, director of the FDA's Food Safety and Security Staff, said that doesn't mean the public should stop washing produce, adding, "If there is surface contamination, washing is going to help remove it."

    Below is a  photo from the Tampa Tribune of a Burger King at Kennedy and West Shore boulevards, indicateing it's not serving tomatoes.

    McDonald' s Corp. said Monday it has temporarily pulled tomatoes from its sandwiches in the United States, a precautionary move in the wake of a salmonella outbreak that has sicken at least 145 in 16 states.

    McDonald's spokesman Bill Whitman was cited as saying the company has not detected salmonella bacteria in any of its tomato supplies, "but with an abundance of caution, we want to make sure our food items containing tomatoes are absolutely safe." McDonald's said it will continue to serve grape tomatoes in its premium salads.

    Winn Dixie in Florida announced they have pulled tomatoes off the shelves, will destroy the tomatoes in stock, and are asking their customers to not eat them. Giant Eagle Supermarkets of Pennsylvania has also pulled a variety of green, yellow, Roma and organic tomatoes off the shelf as a precaution.

    The Tampa Tribune reports that trucks of Florida-grown tomatoes were being turned away by retailers Monday. Florida is not on the list of safe tomato-producing states – those not linked to the outbreak – nonetheless, state agriculture officials say Florida-grown tomatoes are safe to eat and are awaiting clearance from the U.S. Food and Drug Administration.

    Liz Compton, spokeswoman for the state Department of Agriculture and Consumer Services, said,

    "We know Florida's tomatoes are OK. The problem is, they haven't officially cleared us yet, and we are having trucks turned away. … What we know is that the tomatoes that we're shipping now were not being harvested at the time in question."

    Tampa-based Sweetbay Supermarkets and Lakeland-based Publix Super Markets have pulled all of the suspect tomatoes from their shelves.

    Doug and I are attending TrainCan's Food Safety Forum in Toronto today.  The topic of the conference is all around food safety culture and changing behaviour -- which fits really well with the iFSN infosheets.

    In a response to an outbreak of Salmonella linked to certain types of raw tomatoes in the U.S., food service and grocery firms across North America have withdrawn tomatoes from their sites and meals.  The outbreak provided us with the focus of this week's infosheet, which can be found here.

    The U.S. Food and Drug Administration is expanding its warning to consumers nationwide that a salmonellosis outbreak has been linked to consumption of certain raw red plum, red Roma, and red round tomatoes, and products containing these raw, red tomatoes.

    FDA recommends that consumers not eat raw red Roma, raw red plum, raw red round tomatoes, or products that contain these types of raw red tomatoes unless the tomatoes are from the sources listed below.

    If unsure of where tomatoes are grown or harvested, consumers are encouraged to contact the store where the tomato purchase was made. Consumers should continue to eat cherry tomatoes, grape tomatoes, and tomatoes sold with the vine still attached, or tomatoes grown at home.

    On June 5, using traceback and other distribution pattern information, FDA published a list of states, territories, and countries where tomatoes are grown and harvested which have not been associated with this outbreak. This updated list includes: Arkansas, California, Georgia, North Carolina, South Carolina, Tennessee, Texas, Belgium, Canada, Dominican Republic, Guatemala, Israel, Netherlands, and Puerto Rico. The list is available at www.fda.gov/oc/opacom/hottopics/tomatoes.html#retailers. This list will be updated as more information becomes available.

    FDA recommends that retailers, restaurateurs, and food service operators not offer for sale and service raw red Roma, raw red plum, and raw red round tomatoes unless they are from the sources listed above. Cherry tomatoes, grape tomatoes, and tomatoes sold with the vine still attached, may continue to be offered from any source.

    Since mid April, there have been 145 reported cases of salmonellosis caused by Salmonella Saintpaul nationwide, including at least 23 hospitalizations. States reporting illnesses linked to the outbreak include: Arizona, California, Colorado, Connecticut, Idaho, Illinois, Indiana, Kansas, New Mexico, Oklahoma, Oregon, Texas, Utah, Virginia, Washington, and Wisconsin. Salmonella Saintpaul is an uncommon type of Salmonella.


    As I've said, food safety for fresh produce begins on the farm and goes right through to the fork.

    Fresh fruits and vegetables are the most significant sources of
    foodborne illness today in the United States, and because fresh produce is
    not cooked, anything that comes into contact is a possible source of contamination.

    Wash water, irrigation water, manure in soil, even contact with animals or humans, can introduce dangerous microorganisms onto fresh produce. There is evidence that bacteria like Salmonella and E. coli can enter fruit like tomatoes and cantaloupes, and leafy greens such as spinach and lettuce, making removal extremely difficult.

    The farm is the first line of defense.  Whether your produce comes from around the corner or around the globe, contamination must be prevented on the farm.

    Someone came to the blog this morning searching “Salmonella Saintpaul flatulence” inspiring this post. As of last night 138 people in 11 states were sick from Salmonella in tomatoes.

    According to http://www.about-salmonella.com/salmonella_symptoms_risks, Salmonella can cause gastroenteritis, typhoid fever, and bacteremia. The following are symptoms of Salmonella gastroenteritis:
    • diarrhea
    • abdominal cramps
    • fever, generally 100°F to 102°F (38°C to 39°C)
    • nausea, and/or
    • vomiting
    In mild cases diarrhea may be non-bloody, occur several times per day, and not be very voluminous; in severe cases it may be frequent, bloody and/or mucoid, and of high volume. Vomiting is less common than diarrhea.

    Other frequently reported symptoms are
    • headaches
    • muscle pain, and
    • joint pain
    Whereas the diarrhea typically lasts 24 to 72 hours, patients often report fatigue and other nonspecific symptoms lasting 7 days or longer.

    The FDA has a thorough analysis of Salmonella in their Bad Bug Book.

    If you are concerned that you have food poisoning, you should contact your local health unit or Seattle law firm Marler-Clark that specializes in foodborne illness litigation.

    The Dallas Morning News reports that Texas and New Mexico now claim 104 of the 138 cases of Salmonella Saintpaul related to tomatoes in 11 U.S. States. At least 19 people from the two states have been hospitalized. No deaths have been reported.

    The U.S. Food and Drug Administration said that tomatoes grown in Texas, California, Georgia, North Carolina and South Carolina appear to be blameless. Those imported from Belgium, Canada, Dominican Republic, Guatemala, Israel, the Netherlands and Puerto Rico also did not appear to be the source.

    The FDA said preliminary investigations suggest that raw red plum, red Roma or round red tomatoes are the source of the problem.

    Meanwhile, the Washington Health Department said an E. coli outbreak that sickened at least nine people in Pierce and Thurston counties is apparently over and that there have been no new cases since May 29.

    A spokesman, Donn Moyer, said the infection apparently came from romaine lettuce that was served at schools or restaurants. Moyer says health officials haven't been able to identify the source for sure, although the Food and Drug Administration is still investigating.

    "If you read Doug Powell’s FSnet e-mail news, you have probably spotted some of his rants against unsafe techniques demonstrated on television cooking shows."

    So says Gary Acuff, president of the International Association for Food Protection in his June 2008 column about the poor food safety practices of celebrity chefs.

    My rants are based on research, reviewed and published in Food Protection Trends, a monthly journal of … the International Association for Food Protection.

    In 2004, my laboratory reported that, based on 60 hours of detailed viewing of television cooking shows, an unsafe food handling practice occurred about every four minutes, and that for every safe food handling practice observed, we observed 13 unsafe practices. The most common errors were inadequate hand washing and cross-contamination between raw and ready-to-eat foods. The abstract is below and available at http://www.foodsafety.ksu.edu/en/article-details.php?a=3&c=14&sc=102&id=842.

    To answer Gary's question, is there something that can be done? After completing the initial research in 2002, I began writing about the topic, with snappy headlines like, Can TV cooks become food safety celebrities? One of my students at the time, Christian Battista, put together four, 3-minute greatest hits videos, depicting various practices we observed like cross-contamination and lack of handwashing. The videos were a hit.

    Once the paper was published, it made headlines around the globe. Some folks at the Food Network in Canada gave me a call, and said they wanted to work with me and my lab, to enhance food safety on their shows.

    I said sure.

    I also kept showing the videos at my various public appearances.

    And then the Food Network called again.

    This time the folks at the other end were on a speakerphone -- and there was a lot of them. Lawyers, I suspect.

    The Food Network people said if I ever showed the videos again they would sue my ass.

    But YouTube didn't exist back then. And I'm in the U.S. now. Hmmm ….







    Mathiasen, L.A., Chapman, B.J., Lacroix, B.J. and Powell, D.A. 2004. Spot the mistake: Television cooking shows as a source of food safety information, Food Protection Trends 24(5): 328-334.

    Consumers receive information on food preparation from a variety of sources. Numerous studies conducted over the past six years demonstrate that television is one of the primary sources for North Americans. This research reports on an examination and categorization of messages that television food and cooking programs provide to viewers about preparing food safely. During June 2002 and 2003, television food and cooking programs were recorded and reviewed, using a defined list of food safety practices based on criteria established by Food Safety Network researchers. Most surveyed programs were shown on Food Network Canada, a specialty cable channel. On average, 30 percent of the programs viewed were produced in Canada, with the remainder produced in the United States or United Kingdom. Sixty hours of content analysis revealed that the programs contained a total of 916 poor food-handling incidents. When negative food handling behaviors were compared to positive food handling behaviors, it was found that for each positive food handling behavior observed, 13 negative behaviors were observed. Common food safety errors included a lack of hand washing, cross-contamination and time-temperature violations. While television food and cooking programs are an entertainment source, there is an opportunity to improve their content so as to promote safe food handling.

    A total of 11 states, which now include Wisconsin, Virginia and Kansas, have confirmed 112 cases of Salmonella Saintpaul and of those cases, 83 were reported in Texas and New Mexico.

    The U.S. Food and Drug Administration said preliminary investigations suggest that raw red plum, red Roma or round red tomatoes are to blame.

    The agency advised residents of Texas and New Mexico to only eat tomatoes that haven’t been connected to the outbreak, including homegrown, cherry and grape tomatoes as well as those sold attached to the vine.

    They also reminded consumers that fresh salsa, guacamole, pico de gallo and other products may contain raw tomatoes.

    Albertsons has joined Kroger and Central Market in pulling tomatoes from its shelves.

    New Mexico Environment Secretary Ron Curry said Thursday in a statement,

    "The department's food program bureau is contacting distributors of tomatoes to ensure they notify food establishments to stop serving tomatoes suspected in making people sick."

    KRIS 6 News in Corpus Christi, Texas, conducted a random phone survey Wednesday afternoon, and found tomatoes are temporarily not on the menu at Subway, La Playa, Olive Garden, Water Street Restaurants, and Schlotzky's.

    However, tomatoes are still being served at TGI Friday's, Fuddrucker's, Katz 21, Nolan's Poorboys, McDonald's, Mimi's by the Sea, Whataburger, and Wallbangers.

    Reuters reported that even pork bellies are feeling the pressure, as prices fell $4 to $15 per hundredweight in the cash markets on Thursday. The bacon for BLT sandwiches is sliced from pork bellies.

    Seriously, I'm getting tired of using this picture. But I'm not running out of opportunities.

    The Washington State Department of Health said today that  nine confirmed cases of E. coli infection found in Thurston and Pierce counties have been traced to romaine lettuce and a tenth case may be linked but was not tested.

    Health Department spokesman Tim Church says five of the victims were hospitalized, but all have been released.

    The U.S. Food and Drug Administration is tracing the source of the contaminated lettuce.



    A table of known outbreaks of verotoxigenic E. coli -- including but not limited to E. coli O157:H7 -- associated with fresh spinach and lettuce is available at http://foodsafety.ksu.edu/en/article-details.php?a=3&c=32&sc=419&id=903.


    UPDATE: The Department of Health says nine confirmed cases of E.coli infection found in north Thurston and south Pierce counties have been traced to bagged, commercial romaine lettuce.

    Health officials say it's not the same type of lettuce you would buy in a grocery store.

    The AFP is reporting today that “real” camembert makers can rejoice. In addition to reducing the geographic boundaries of the camembert region, now the only camembert makers that will be recognized with the prestigious AOC (appellation d’origine contrôlée) label will:
    -    use only raw milk;
    -    have at least half of the cows providing the milk from Normandy origin; and,
    -    ensure that their cows graze on Normandy pastures for at least 6 months of the year and fed hay the remainder of the time.
    The grazing restrictions are new to the AOC conditions. I find them particularly surprising as research has shown that grass-fed or not, all cows can carry E. coli O157:H7.

    The “real camembert” supporters apparently found the decision to be “undeniable progress.” Lactalis and Isigny-Sainte-Mère, two large companies that previously produced more than 80% of AOC Camembert, decided last year to begin heat-treating their milk as a safety measure.

    Francophiles, can read today's original story for themselves. The French clearly articulate that the raw milk camembert has a velvety taste compared to the pasteurized version, but that the traditional methods are more onerous because they require various testing measures to avoid pathogens such as listeria. According to my favorite food safety advisor, you cannot test your way to safe food. The new and improved camembert will have enhanced risks.

    The Star Tribune is reporting that seven illnesses have been reported in Minnesota among people who have handled baby chicks or ducklings, the state Health Department reported this morning.

    The cases of salmonellosis occurred from late March through late May, the department said, adding that those falling ill were ages 5 months to 70 years old.

    Two people, the 5-month-old and a 42-year-old, required hospitalization for a few days.

    Dr. Joni Scheftel, the department's public health veterinarian, said,

    "In a typical year, a handful of the approximately 700 salmonella infections diagnosed in Minnesotans are linked to contact with chicks and ducklings."

    The Health Department offered these guidelines to avoid infection:

    • Do not let children less than 5 years of age handle poultry.

    • Wash hands thoroughly with soap and water after handling poultry or their droppings.

    • Do not eat or drink around poultry or their living areas.

    • Do not let poultry live inside a home.

    • Do not wash the birds' food and water dishes in the kitchen sink.

    Same thing happened last year, and pretty well every other year.

    And don't kiss pet turtles, no matter how emotionally deprived you are as a child.

    Farmers Guardian is reporting that UK government veterinarians, in the interest of an open and frank discussion, have been told to sit quietly and not express their views on whether badgers should be culled to control bovine TB -- unless their opinion agrees with whatever the government decides to do.

    In a circular email, seen by Farmers Guardian, the Defra agency has told all its staff that a major announcement from Defra on TB policy, including the decision on badger culling, is expected ‘within the next few weeks’.

    The message, sent by Animal Health field services director Andy Foxcroft, says it is ‘essential that all members of Animal Health are seen to support Government policy’ whatever decision is made, stating, “I appreciate that this maybe challenging, given the strong views some of our customers groups hold about the issues. However, I know that you will appreciate that it is critical. Therefore, all Animal Health staff who come into contact with customers, either by telephone or in person, will be expected to not express any disagreement with the Defra position on TB strategy at any stage."


    A former state vet, who  asked to remain anonymous, said old colleagues were ‘surprised’ by the email that smacked of ‘paranoia.’

    An Animal Health spokeswoman said the agency had "taken the opportunity to remind our staff of the need to support" Defra policy, whatever decision is made in order ‘to ensure there is no confusion."

    "Farmers need one clear message on the position on bTB."

    Australian Prime Minister Kevin Rudd said party pie or something else savoury -- not a dagwood dog -- may have been responsible for a vomiting bug that felled him last month.

    His office yesterday blamed a "dodgy dagwood dog" for the illness, but Mr Rudd suggested today it might have been a pie, stating,

    "I think it was a party pie, something like that, a savoury something. All I know is whether it was that, or whether it was a stomach bug, the consequences were graphic."

    Dagwood dogs are sausages, deep-fried in batter and served on a stick.

    An investigation commissioned by the Chartered Institute for Environmental Health (CIEH) Wales found that one in five samples of ice tested from hotels and pubs in Cardiff and the Vale of Glamorgan were contaminated with fecal matter -- probably because staff are not washing their hands before serving customers ice in their drinks.

    Julie Barratt, director of the CIEH in Wales, said,

    “The results of the survey give us cause for concern. Although realistically there is little likelihood of food poisoning from the levels of bacteria that were found, the presence of fecal bacteria shows that the people handing the ice have very poor standards of personal hygiene. While the ice may pose little risk the same may not be true for other foodstuffs that they may also handle. Food business operators and food handlers need to recognise that ice is a food product and treat it in the same way as all other foods prepared for sale to the public.”

    The Chartered Institute for Environment Health in Wales has put together these tips for when asking for ice in a drink:

    • if the ice is in a bucket on the bar where anyone can lean over it or cough or sneeze on it, don’t have it;

    • if the bar tender takes the ice out of the bucket with their hands, don’t have it;

    • if the bar tender pushes a glass down into the ice and their hands come into contact with it, don’t have it;

    • if the scoop or tongs for handling the ice are not stored properly, don’t have the ice – you wouldn’t chose to have meat cut with a dirty knife;

    • if you can see the ice machine, and it looks grubby, don’t have the ice that comes from it; and,

    • if the ice bucket looks dirty, don’t have the ice that comes out of it.

    Following the June 3 announcements by the U.S. Centers for Disease Control and the Food and Drug Administration about the latest Salmonella outbreak related to tomatoes, at least two retailers, San Antonio-based H.E. Butt Grocery Co., and Cincinnati-based The Kroger Co. pulled round red and Roma tomatoes off the shelves in Texas locations.

    The Houston Chronicle interviewed several shoppers.

    Anthony Castillo, who was among shoppers at a Randalls at 3131 W. Holcombe, said,

    "This kind of freaks me out. I think I'll be going sans tomatoes for a while."


    Shopper Rachell Cobb-Valion said,,

    "They are always telling you to eat more fruits and vegetables, but you can get as much poisoning from them as when you eat meat."

    Tomato lover Bobby Kimble said,

    "It doesn't bother me at all. Nothing ever bothers me. If it goes in my stomach, it's gone."

    The U.S. Centers for Disease Control has just issued a statement about the ongoing outbreak of Salmonella St. Paul

    "An epidemiologic investigation conducted by the New Mexico and Texas Departments of Health and the Indian Health Service using interviews comparing foods eaten by ill and well persons has identified consumption of raw tomatoes as the likely source of the illnesses in New Mexico and Texas. The specific type and source of tomatoes are under investigation; however, preliminary data suggest that large tomatoes, including Roma and red round are the source.

    Since late April, 40 persons infected with Salmonella Saintpaul with the same genetic fingerprint have been identified in Texas (21 persons) and New Mexico (19 persons). The New Mexico Department of Health is investigating 17 additional Salmonella Saintpaul illnesses. These were identified because clinical laboratories in all states send Salmonella strains from ill persons to their State public health laboratory for characterization. Among the 38 persons who have been interviewed, illnesses began between April 23 and May 27, 2008. Patients range in age from 3 to 82 years; 48% are female. At least 17 persons were hospitalized. No deaths have been reported."

    Advice to consumers
    In New Mexico and Texas, until the source of the implicated tomatoes is determined,

        persons with increased risk of severe infection, including infants, elderly persons, and those with     impaired immune systems, should not eat raw Roma or red round tomatoes other than those sold     attached to the vine or grown at home, and
        persons who want to reduce their risk of Salmonella infection can avoid consuming raw Roma or     red round tomatoes other than those sold attached to the vine or grown at home.

     • Avoid purchasing bruised or damaged tomatoes and discard any that appear spoiled.
    • Thoroughly wash all tomatoes under running water.
    • Refrigerate within 2 hours or discard cut, peeled, or cooked tomatoes.
    • Keep tomatoes that will be consumed raw separate from raw meats, raw seafood, and raw produce items.
    • Wash cutting boards, dishes, utensils, and counter tops with hot water and soap when switching between types of food products.
    You can check the CDC and FDA websites for updates on this investigation and changes in recommendations.


    A table of tomato-related North American outbreaks is available at
    http://www.foodsafety.ksu.edu/en/article-details.php?a=3&c=32&sc=419&id=953.

    Tomatoes are one type of fresh produce where it appears pathogens like Salmonella can be internalized, which means washing is of little use. The problems need to be prevented on the farm. Regulators and the industry in the past have released food safety guidelines for tomatoes, but there is a lack of verification; it is unclear if all growers are actually following the guidelines.

    Guidelines are a first step, but more creative ways are required to compel everyone, from the person harvesting to the person distributing, to take food safety seriously, even in the absence of an outbreak.

    A Dunedin, New Zealand, City Council Environmental Health Inspector was called to a Union Street Flat recently after several complaints of a dismembered pigs body having been disposed and left on the street and a property.

    Health Inspector Judy Austin attended the scene with two Campus Watch officers and a security guard to find blood, skin and the remains of entrail on the street, and the head and trotters of the pig inside the property boundary but close to the public footpath.

    Austin said wild pigs can carry diseases such as E-coli, Trichinosis and Brucellosis, so the risk of having an outbreak of disease was possible.

    Campus watch issued the tenants with a $100 fine under the Litter Act.

    The practice of people eating insects, that is.

    The New Zealand Herald reports that scientists at the National Autonomous University of Mexico have catalogued 1,700 different species and found that bugs are eaten in at least 113 countries worldwide.

    David George Gordon, a Seattle-based naturalist and author, said,

    "Insects are the most valuable, underused and delicious animals in the world,"  and the West "is one the few cultures" that doesn't eat them. "Maybe we are the weirdos."

    A plate of maguey worms - larvae of a giant butterfly - sell for NZ$31.50 in smart Mexican restaurants (right).

    In our continuing spotlight on public toilets, USA Today reports that cities are increasingly placing self-cleaning, automated public toilets in high-pedestrian-traffic areas.

    Mary Ann Racin, founder of thebathroomdiaries.com, a website that rates more than 12,000 public restrooms worldwide, said Los Angeles, San Francisco, Boston, New York, Pittsburgh, Atlanta and San Antonio are some of the cities that have automated public toilets (APTs), with most in the past five years.

    Atlanta was the most recent to add them, in March, paying $300,000 for each of the five units and signing a two-year maintenance agreement for $1.5 million.

    With the push of a button, and the drop of a quarter depending on the city, the automated door opens, and a sanitized toilet awaits. After the user is finished, the system cleans the toilet and is ready for the next user.

    Not all cities are happy: Seattle has moved away from its program after a report prepared by the City Council said the APTs became a haven for drug use, drug deals and prostitution.

    The Canadian Food Inspection Agency (CFIA) is warning the public not to consume the KingFisher brand cantaloupes described below because these cantaloupes may be contaminated with Salmonella. 

    The affected cantaloupes, produce of the United States, were distributed under KingFisher brand name in cartons containing 6 or 9 cantaloupes.  The individual cantaloupes may have a sticker with the following information:

    KingFisher Brand
    Produce of USA
    UPC : 0 33383 11600 6
    #4050
    Fisher Ranch Corp., Blythe, CA, 92225

    These cantaloupes were distributed in Ontario and sold from May 16 up to and including June 2, 2008.

    Consumers who have purchased whole cantaloupes or in-store products containing pieces of fresh cantaloupes and are not sure of the brand should inquire at the place of purchase to verify if the stores have received the affected product.

    There have been no reported illnesses associated with the consumption of these cantaloupes.

    I'm an advocate for asking questions.

    Where was that fresh produce grown? What temperature is medium-rare? Did the cook wash his hands after going to the bathroom?

    I also recognize that most people -- including me -- feel socially awkward asking such questions.

    So, would you ask your doctor if he has washed his hands?

    That's what Carmela Fragomeni of The Hamilton Spectator in Canada asked this morning.

    Hamilton resident Maria Pimentel says,

    "I'm not comfortable to ask him because maybe he'd get upset."


    Linda VanRysell believes doctors would always automatically be washing their hands before examining a patient, stating,

    "I assume they're professional."


    Dr. David Higgins, chief of staff at St. Joe's in Hamilton, said if he were to fail to wash his hands, he hopes patients would called him on it, adding,

    "I should thank the person for doing it. That's the ideal culture."

    Information about risk -- specifically the microbiological risks in food and water -- needs to be rapid, reliable, relevant and repeated. Often those with the most information and the most credibility in an outbreak situation are the local medical officers of health, or some other government-type.

    And they often don't say much.

    But there are examples of officials doing their jobs and being accountable to the public they serve. In the aftermath of the first case of homegrown bovine spongiform encephalopathy in Canada in May, 2003, Brian Evans, the chief veterinarian for the government of Canada, did an excellent job of explaining here's what we know, here's what we don't know, here's what we're doing to find out more, and whatever we find out, you'll hear it from me first.

    Two public health officials have stepped out in the past two days and offered their analysis on a couple of persistent health risks: raw milk and parasites in swimming pools.

    Yesterday, Dr. Stephen Ostroff, director, Bureau of Epidemiology, Pennsylvania Department of Health, wrote in the Lebanon Daily News that,

    "In light of recent discussions pertaining to raw-milk health issues, the Pennsylvania Department of Health continues to advise consumers that raw milk is an inherently unsafe product regardless of how it is produced. While the permitting process unquestionably enhances the safety margin of raw milk, and we strongly endorse this program, it is not a substitute for milk pasteurization.…

    Last year, an outbreak of salmonellosis due to consumption of raw milk sold in south-central Pennsylvania produced 29 illnesses. Sadly, many of the victims were children who had no choice in the kind of milk their parents purchased for them. Indeed, the department is currently investigating another raw-milk-associated outbreak of campylobacter infections. So far, more than 54 illnesses have been reported.

    While standard hygiene and production practices can reduce the risk from consuming raw milk, they simply cannot eliminate it. In a 2006 survey of Pennsylvania dairy farms, pathogens were found in 13 percent of bulk tank raw-milk samples. Therefore, the department believes it is necessary to warn consumers about the risks associated with raw milk and to urge persons with immune disorders, pregnant women and young children to avoid consuming this product in the interest of protecting the public’s health."


    Today, David N. Sundwall, executive director of the Utah Department of Health, wrote in The Salt Lake Tribune that,

    "The UDOH, along with our partners at Utah's local health departments, carefully considered whether to restrict young children from pools. Young children are more likely to become ill from crypto and more likely to leave poop in the pool. While it might seem like common sense to ban them, we cannot say that they caused the outbreak or that banning them would prevent another one.
    Children have been swimming in public pools in Utah in past years when outbreaks didn't occur. To our knowledge, no state bans children from public pools. Older children and adults, who have control of their bowels when healthy, are also susceptible to "leaking" if they swim with diarrhea.

    We chose to continue to allow children to swim with swim diapers and waterproof swim pants. We believe this will help prevent contamination of the pool, but it isn't foolproof.

    Parents of young children need to act responsibly and with common sense. They need to monitor their children and give them frequent potty breaks. Most important, they need to keep them out of the pools when they are ill with diarrhea and for two weeks afterward.

    The UDOH takes seriously its responsibility to protect people from health threats like cryptosporidium. After last summer's outbreak, we considered multiple measures to help prevent a recurrence this summer. Preventing crypto transmission will require a combination of changes at pools and changes in behavior."


    Both Ostroff and Sundwall are too be commended. You may not agree with what they say, but at least you know why they came to the positions they advocate. Public health types, please speak out.

    Health officials have announced that those cases of Salmonella St. Paul that have been popping up in New Mexico for the past three weeks have been linked to fresh tomatoes.

    Dr. Mike Landen, deputy state epidemiologist with the Department of Health, said,

    "We have alerted physicians and hospitals around the state to be on the lookout for people presenting with fever and diarrhea and to test those people for salmonella. We are asking the public to take general precautions to avoid being exposed to salmonella and to seek health care if they develop a severe illness with fever and diarrhea."

    The department says some of the infected tomatoes were bought from a Wal-Mart in Las Cruces or Farmington, a Lowe's in Las Cruces or Bashas' in Crownpoint. But they say other stores are probably selling the tomatoes too.
    Health officials are still trying to pinpoint which tomatoes are carrying the bacteria.

    A table of tomato-related North American outbreaks is available at

    Tomatoes are one type of fresh produce where it appears pathogens like Salmonella can be internalized, which means washing is of little use. The problems need to be prevented on the farm. Regulators and the industry in the past have have released food safety guidelines for tomatoes, but there is a lack of verification; it is unclear if all growers are actually following the guidelines.

    Guidelines are a first step, but we need more creative ways to compel everyone, from the person harvesting to the person distributing, to take food safety seriously, even in the absence of an outbreak. Here are some references for the work we've done.

    We also published a book chapter entitled Implementing On-Farm Food Safety Programs in Fruit and Vegetable Cultivation, in the recently published, Improving the Safety of Fresh Fruit and Vegetables.
