Food Poisoning, Foodborne Illness Information and Research : International Food Safety Network : BarfBlog

Last Friday the family and I embarked on a journey from Raleigh, NC to Port Hope, ON (Canada) to visit with our folks and celebrate our son Jack's 1st birthday. Dani and I had a strategy to limit the potential baby-craziness aspect of the 14-hour trip: leave mid-day and drive late into the night to perhaps let Jack's internal schedule take over and allow him to sleep for the majority of the ride.

Surprisingly, that plan worked perfectly.

Jack fell asleep around 7pm and did not wake until Dani abruptly woke him up with some spectacular barfing somewhere around Scranton, PA. She had been feeling car sick since about 30 minutes after we left and had fought it for a few hours, in her words, it "just came up". It surprised her enough that she felt she didn't have time to roll down the window, or even open the door. Sitting in the passenger seat, she turned to her left and decided to try to catch the barf in an empty cup she had sitting in the console. Bad idea. She filled the cup, and then both cup holders on the console. And then all over my leg and shoes.

Reminiscent of Lardass Hogan (see Stand By Me clip, below) I had a sympathy puke.

This ranks pretty high in my all-time vomit memories. It's up there with puking in Doug's flower bed; trying to catch vomit in my hands while sitting in a car and throwing it out the window (didn't work); deep-sea fishing induced illness and another Dani car story where she opened the window but decided to puke on the inside of the door instead. The most recent has made the top-5.

Jack fell back asleep soon after we stopped to clean up. But the car still smells like barf.

Foodborne illness can be an unpleasant experience or something more serious. The World Health Organization estimates up to 2 billion people get sick from food and water each year – 30 per cent of all citizens in all countries.

Dr. Douglas Powell, associate professor of food safety at Kansas State University, leads a group of individuals passionately committed to reducing the incidence of foodborne illness, through research, teaching and information. The group strives daily to be the international leader in comprehensive and compelling food safety information that impacts individual lives – and reduces the number of sick people.

The electronic publications, barfblog.com and bites.ksu.edu, are comprehensive, current and compelling sources of food safety news and analysis, and help foster a farm-to-fork culture that values microbiologically safe food.

Research
•    The effectiveness of food safety messages and media in public discussions of food safety issues, such as the risks of listeria to pregnant women, legislation surrounding raw milk, public availability of restaurant inspection data, and the safety of fresh produce, are evaluated through qualitative and quantitative methods.

•    Observational research methodologies are used to quantify individual food safety behaviors from farm-to-fork, to enhance handwashing compliance, thermometer use, food packaging information and interventions that can reduce the number of people that get sick from the food and water they consume.

Teaching
•    A graduate program in food safety risk analysis – including food safety, language, culture and policy -- is being developed and will include distance-education.

•    Courses are currently taught in Food Safety Risk Analysis, and Food Safety Reporting.

Information
•    Dr. Powell is the publisher and editor of bites and barfblog, rapid, reliable and relevant sources of food safety information. Dr. Ben Chapman of North Carolina State University is the assistant editor.

•    bites and barfblog are produced by a cross-cultural team of secondary, undergraduate and graduate students as well as professionals who create multilingual and multicultural food safety and security information, including weekly food safety information sheets, and multimedia resources.

•    Research, educational and journalistic opportunities are available for secondary, undergraduate and graduate students through bites.ksu.edu and barfblog.com.

At barfblog we're all about community-generated content. It's fun when someone emails with a food safety-related story or a picture for us to share.  Today's content comes from a colleague and avid barfblog groupie who was driving through southern Georgia this morning and snapped the picture at right.

The pictured sign is posted at the entrance of a pecan and peanut company's roadside market/shop. All I know about this unidentified business is that it distributes stuff like raw, roasted and nut products all over the U.S. 

Sure, it's a good idea to keep dogs out of the food area of a store, but suggesting to take a walk in the orchard, an equally important food area, is kind of weird.

To me, it seems like the producer should be thinking their orchard is a food area as well. Sure, it's really tough to control birds, deer and feral pigs, but inviting dogs to take a dump in the orchard (something that is controllable) probably isn't a good idea.  In the climate of uncertainty around the effectiveness of pathogen reduction strategies in the nut industry, it's an especially bad idea.

Keep the dog poop out of the orchard.

Karla Cook writes in tomorrow's New York Times that the Peanut Corp of America-linked Salmonella outbreak's reach has not been limited to multi-national companies:

Small businesses in all corners of the United States bought potentially tainted peanut products from the Peanut Corporation of America and are now part of one of the largest food recalls ever in this country. There is the chef in Las Vegas, for instance, who used them in protein bars, the packager of nuts and dried fruits in Connecticut, the cannery in Montana that sold chocolate-covered nuts and the ice cream manufacturer in New York State.

While big companies like Kellogg, Kraft and General Mills have the experience and staff to handle recalls, many small businesses have never had to deal with anything like this.
Some have had to keep employees on overtime or hire additional help to handle the recall-related work — records have to be searched to identify and track products, and replacement products manufactured. And company officials say they are spending a lot of time reassuring their customers.
“It’s not our fault this recall went through,” said Tom Lundeen, who co-owns Aspen Hills Inc., in Garner, Iowa, which makes frozen cookie dough for fund-raisers. “We do everything correct and we have an incredibly high level of quality control, and we still have to pay for the mistakes of P.C.A.”

Yep, exactly - this outbreak has demonstrated the complexity and interconnectedness of the food system -- which has largely been built on trust in suppliers or the results of their third-party audits.

Jenny Scott, a microbiologist and vice president of science policy and food protection for the Grocery Manufacturers Association, a trade group in Washington, said small businesses need to know their suppliers’ food safety culture and practices, and whether the suppliers are capable of doing the right thing. Last week, she helped teach a Web seminar for 60 participants, “The Ingredient Supply Chain: Do You Know Who You’re in Bed With?” 

Like it was straight out of the pages of barfblog -- although trying to assess the food safety culture and supplier practices is difficult, it's not impossible. Creating and fostering the openess and transparency of food production through marketing food safety, with companies opening their doors can help buyers make decisions.

Benjamin Chapman, food safety extension specialist at North Carolina State University in Raleigh, went further. “If you’re in the peanut butter industry, you need to be thinking about salmonella,” he said. Learning about suppliers is challenging when the supplier is not local, and the layers of the national food system are difficult to pierce.

SunHerald.com is reporting an outbreak of Salmonella at a maximum security prison in Jackson County, Mississippi:

The state Health Department is currently trying to determine what food could’ve caused a salmonella outbreak at the maximum-security jail this week.
The outbreak sent five inmates to the hospital, though only one remains hospitalized, officials said.
Jackson County Sheriff Mike Byrd said the inmates started getting sick, suffering mostly from diarrhea and abdominal cramps, on Monday, with two the inmates experiencing a low-grade fever. The sheriff said the jail gets its food from an international food services company.

He said the ingestion of peanuts or peanut butter has been ruled out as the possible cause of the illness. He said, so far, officials believe the potentially life-threatening bacterial infection could’ve been caused by some lettuce that the food services company provided and the inmates ingested.
The Sun Herald updates this story in Thursday’s edition.

Lettuce and leafy greens have most often been associated with pathogenic E. coli in outbreaks, but food handlers have been known to shed Salmonella without showing symptoms.

As a follow-up to last week's kebab/street meat post, today, the FSA published results of a survey of the content of 494 kebabs across the UK.

The study's authors report that without salad and sauces, the average kebab contains:
* 98% of daily salt
* nearly 1000 calories
* 148% of daily saturated fat

The authors also report the mislabelling of kebab meat, with meat species not declared or declared wrongly. In some instances, pork was present in samples labelled as Halal.

The Food Standards Agency’s Chief Scientist Andrew Wadge said:
'We welcome this new study. It is important that people are properly informed about the food they eat. However, our advice is that people don’t need to avoid doner kebabs altogether because of these findings. Like all types of food that is high in fat and salt they do not need to be cut out of your diet altogether."

Wonder if they sampled for pathogens, and if they found any.

Following up on my last post on the passing of the dude who helped create the microwave (and indirectly, caused lots of illnesses in Minnesota) there's news out of Germany that the creator of the kebab (or donair as it's known in Halifax or Calgary) has passed away.

 Mahmut Aygün, snack visionary and dab hand with a meat carver, has died of cancer at the age of 87, almost 40 years after permanently changing the drunken dining habits of millions.

The chef was born in Turkey but later moved to Germany in the hope of one day opening his own restaurant. He was serving customers at a snack stall when it dawned on him that kebab meat – a mix of roasted lamb and spices traditionally eaten with rice – could be served differently.

'I thought how much easier it would be if they could take their food with them,' he once said.

 (in celebration of the Conchords returning to HBO -- the line "I'll buy you a kebab" is at 2:11)

Donairs have been linked to at least three outbreaks of E.coli O157 in Alberta since 2004. Outbreak investigators found that the cooking practices traditionally used in kebabs and donairs, rotating a cone of meat around a heat source, were problematic.  Often, especially in the post-bar-closing rush, the heat sources are turned up so the outside of the cone gets scorched, but meat just below the surface doesn't reach safe temperatures (because it's being cut off quickly to meet the customer demands).  The cooking practice, along with the tendency for the meat cones to be made with ground meat and stored frozen can cause a perfect outbreak scenario.

And then cause the squirts. Or worse.

In response to the outbreaks a national committee was created in Canada to look at the risks associated with the food.  The group recommended that donairs/kebabs/shawarmas/street-meat-on-a-stick should be grilled after cutting off the cone to ensure pathogen-killing temps.  Good call.

I'm all for donairs and street meat. Or late-night chinese food.  Basically anything heavy and greasy tastes good after a few beers, but the places serving them have to know the risks associated with what they are serving, and where things might go wrong. Public health officials and food safety folks need to help businesses with this. If you don't know what could go wrong, you shouldn't be serving it.

Here's a food safety infosheet on donairs from a couple of years ago.

As Doug posted earlier, it looks as though peanut butter has been implicated in the current 400+ person outbreak of Salmonella Typhimurium.  Earlier tonight AP cited CDC sources as saying that the Salmonella also may have contributed to three deaths. AP reports that it looks like Minnesota Dept of Health has yet again cracked the case and recovered the outbreak strain from an opened jar of King Nut brand peanut butter, and has epidemiolgy to back it up:

"The commonality among all of our patients was that they ate peanut butter," said Doug Schultz, a spokesman with the Minnesota Department of Health. While the brand of peanut butter couldn't be confirmed in every case, the majority of patients consumed the same brand, he said Monday.

Here's a food safety infosheet that focuses on the outbreak. You can download it here.

I'm a total food safety nerd. I even use big food safety events to remember when things in my life happen.  Had I not emailed Doug in the winter of 2000 looking for an on-campus summer job at Guelph, I'm sure I wouldn't be doing that.

The story would be a lot cooler if I had sought out Powell as a potential employer because I was interested in the stuff he did, but I didn't. I had no idea what he did -- and being a bit of an idiot, I didn't bother to look it up. I emailed Doug on the advice of a friend, and former Powell Lab-ite, Lindsay Core. Lindsay knew I was desperately looking for a job, and didn't tell me much else about the dude or what he filled his days with. Lindsay just said "I think you two will get along".  I didn't really know what that meant, but really had no other prospects.  So I emailed him. And he hired me to pull news.

Pulling news meant that I surfed through the tubes of the interweb for anything food risk-y (food safety, GE crops, animal disease, etc) and the stories I found (along with the other news pullers) become the content for FSnet and the other listserv postings Doug puts together every day.  Doug's philosophy fit in with what I was looking for -- he never really cared where I was as long as I could be found with an email and that I would get something to him when he needed it.

About three weeks in, I fell in love with the content and became hooked on food safety communication. That's when an E.coli O157 outbreak linked to Walkerton Ontario's town water system hit. I was already interested in disease (maybe it was because of Outbreak or the Hot Zone?), but the coverage and discussion within the Powell lab around Walkerton (how the outbreak was handled and communicated to the folks drinking the water) drew me in. I knew it was time to move from molecular biology and genetics to food safety. So finding what I really liked is linked in my mind to the 2000 Walkerton outbreak.

That's where it all started.

I equate a May 2003 trip to Dani's graduation from Dalhousie in Halifax with the news of the first Canadian BSE case. On the way home, I saw Doug on the in-flight CBC newscast talking about how CFIA has handled things (and thought, even when I'm away from Guelph for three days Powell and food safety follow me).

In 2006 I was about to leave for a trip to Kansas to visit Doug, and begin the initial evaluation of the food safety infosheets, when the E.coli O157:H7/spinach outbreak broke. When I arrived in Manhattan it was all E.coli O157 and spinach for us. The picture that Christian created with the skull and leafy greens (right) became a signature picture amongst the food safety infosheet pilot participants. Those pilots, and conversations with Doug and Amy in their living room, evolved into video observation of food safety practices -- one of the things I've spent the past couple of years on.

I'll always remember 2008 for a bunch of personal things (having a kid, getting hitched, getting a position at NC State and moving to North Carolina) -- and will probably equate it to Maple Leaf Foods, Listeria monocytogenes and Michael McCain (who was just named Canadian Business Newsmaker of the Year -- kind of like OJ being named US Sports Newsmaker of the Year?).

In my time spent in the various incarnations of FSN/iFSN/barfblog/Powell's lab, I've seen Doug's hair catch on fire; been accosted in a hot-tub (not by him) while in Phoenix with him; got lost on a trip with him in snowy, -20C Montreal without my coat; threw up in his backyard; talked about a ridiculous amount of pop culture with him; started a company with him and Katija; translated Kiwi accents for him; and, maybe most importantly, went to see Neil Young with him.

We've golfed, played squash and hockey together. Each of which he beat me at, and often reminds me of it. He also likes to point out, and I never argue with him, that I owe him. I do; although it's a bit like owing something to Tony Soprano.

There's lots of stuff I've left out of the post because it's hard to write about 8 years in 750 or so words, but through all the fun stuff and late-night emails, Doug has shown me how to create a lifestyle around food safety where working and vacations blend together.

Doug's got lots of friends, former friends and never-friends. The ratio is probably about 1:1:1. Some food safety folks have told me that they wish he was nicer. I'm glad he's not. His skepticism and cynicism (and sometimes lack of tact) makes him great at what he does, and have made him the perfect mentor for me.

So enough of this post being about Doug, it's really about me. On Monday I start a faculty position in the Department of 4-H Youth Development and Family & Consumer Sciences at NC State University as food safety extension specialist.  I'm excited as I get to support extension agents throughout North Carolina; develop food safety programs to be delivered from farm-to-fork; and, conduct applied research on food safety. It doesn't sound like a job to me. $550 for season tickets to the Hurricanes, and about three hours to Myrtle Beach are added bonuses.

Dani, Jack and I left Canada a week ago for the USA. Our furniture will arrive sometime next week, so for now we're minimalists. We're currently camping indoors, with only an air mattress, lawn chairs and a 42" television (I guess the TV isn't really camping equipment, but whatever).

On Tuesday night we picked a whole chicken up at Target and decided we'd roast it, but forgot that in our equipment-less situation we didn't have our trusty PDT 300 to take the temp. 

The juices were running clear.  The chicken was piping hot (even a bit crispy) but after I had my first couple of bites I noticed that the meat close to the center looked pretty raw.

We went and got an interim thermometer at Target yesterday.


The Monday start date hinges on me not coming down with Campylobacter or Salmonella.

Doug sent me an email a couple of nights ago (while we were chatting about the fantastic Canada/US World Junior Hockey Tournament game) that said "you your own dude at NC State" (he's one arm typing with Sorenne lately).  Yep. That's true, but I wouldn't be my own dude here if it wasn't for him, and I'm excited to work on more great stuff together.

Being a food safety nerd, I’ve had a lot of fun developing food safety infosheets over the past 5 years. The idea behind the infosheets is to take stories, add some humour/shock/kitch and generate dialogue around food safety.

The turkey food safety infosheet is generating a lot of interest. I’m no Sarah Palin, but most responses have been from over-eager gotcha folks who are pointing out what appears to them to be serious food safety errors (especially around thawing, stuffing and cooling leftovers). Some have been nice; others, not so much.

Our focus in building the food safety infosheets is to provide practices based on the best available science. And sometimes what the FDA Food Code, USDA FSIS consumer education and published peer-reviewed articles say around food safety practices differ.

Go figure.

We base the food safety infosheets  on the best available science, not jurisdictional regulation. It’s our way of being consistent because recommendations changes so much from location to location (Canada and the U.S. recommend two different temperatures for endpoint temp for poultry: 165F in the U.S., and 180F in Canada -- both countries apparently looking at the same data).

People seem to get especially antsy when we disagree with the regulators. Everything we put in "what you can do" section of the food safety infosheets has to have references to back it up (which sometimes the regulatory recommendations do not).

Here are the references for the 3 recommendations folks have mentioned the most (thawing, cooking stuffing to 150F and cooling leftovers)

Thawing on the counter:

Lacroix BJ, Li KW, Powell DA. 2003. Consumer food handling recommendations: is thawing of turkey a food safety issue? Canadian Journal of Dietetic Practice and Research, 64(2): 59-61. (this whole paper can be found at the bottom of this post)

Lee M. 1993. Methods and risks of defrosting turkeys. Environmental Health Review (Winter):96-100.

OP Snyder, 1999. Thawing at ambient temperature on the counter. Hospitality Institute of Technology and Management, St. Paul, MN USA.

Stuffing:

The 150F recommendation is based on a 6-7 log reduction of salmonella in stuffing at 140F for 12.7 min (pathogen destruction is time/temperature, and it will take that long to take the stuffing from 140-150. Pete Snyder's Turkey HACCP document explains it well (second paragraph on page 2).

From the doc:

As expected, no salmonellae or staphylococci was recovered.  They were killed above 130°F as the turkey was cooking.  Actually, if the stuffing had been sampled at 140 to 150°F, they would have found that these organisms would be dead, considering that 140°F for 12.7 minutes gives a  7D reduction of Salmonella in beef.

Cooling:

Turkey should be refrigerated within 2 -- and continuously cooled reaching 41F within 15 hours.  Pete Snyder also has a referenced cooling paper that explains this well.

from the doc:

In 1992, this author received an agreement from Ray Beaulieu and Jeffery Rhodehamel at the FDA that there was indeed no scientific basis for the FDA retail food cooling regimes, and that it was appropriate to do a study. With the help of Dr. Vijay K. Juneja, USDA ARS ERRC, a study was conducted using hamburger as the food item and C. perfringens as the target organism (Juneja, 1994). Clostridium perfringens was selected, because, of the three spores, C.perfringens has the shortest lag and fastest generation time.

Hamburger was selected as the media, because C. perfringens is found in hamburger, and hamburger has often been involved in C. perfringens outbreaks. Various cooling times were evaluated in order to determine the safe cooling time. One cooling time chosen arbitrarily was 15 hours to go from 130 to 45ºF, with a 38ºF temperature of coolant, in this case, air in the refrigerator. The 15-hour cooling time showed about 3 multiplications of C. perfringens. The USDA has accepted this cooling time as safe (Federal Register, January 6, 1999), because it now accepts cooling when there are 3 or less multiplications of C.perfringens.

As I replied to one interested subscriber, here are our references, show us yours.

Don't go to work if you are ill. 

It's easy to say, but hard to do.  Especially if you are a food handler supporting a family, and you don't get paid for sick days.  Or if you are a line cook and your boss tells you that she really needs you to show up because someone is already sick.

Indiana, like other juresdictions around North America has a law that says if a food handler has one of a handful of illnesses that can be passed to the public through food, they need to stay home. Indiana's list includes: Salmonella, shiga toxin-producing E. coli, Shigella, hepatitis A and norovirus.

According to the Star Press, the Delaware County (IN) Health Department is starting to crack down on food establishments that lack a policy of excluding employees from work if they have one of the five illnesses: "A recent informal survey revealed operators typically could not name any of the five reportable illnesses, or name the reportable symptoms," the Indiana State Department of Health reports in its Winter 2008 newsletter Food Bytes. "Only a few could name any symptoms and perhaps name one reportable illness.

Why hasn't the law been enforced before now?

"It was sort of like, not a hidden rule, but not a very well understood rule," said Terry Troxell, food division supervisor at the county health department. "No one knew its importance. Now, after we've become standardized by the state, it's one of the things being picked up on during inspections."

This week's Food Safety Infosheet is all about why it is important to stay home if you are ill, and stay away from food handling until you stop shedding the pathogen in your poop and puke.

Clean it up.  That's the easy answer.

Exactly how is another question.  After Amy's story of one of her students yacking in class, we started tossing around that question and using norovirus outbreaks at Georgetown and USC as hooks. Mayra and I decided to build a food safety infosheet around it.  After reviewing available guidelines from regulators and peer-reviewed research publications, we came up with some steps for cleaning up vomit. 

We based our recommedations on a norovirus-induced vomit (because aerosolized spread of virus particles is likely). 

If you are looking for a cool paper on vomit, check out: Evidence for airborne transmission of Norwalk-like virus (NLV) in a hotel restaurant (Epidemiology and Infection, 2000. 124:481-487), which discusses the spread of post-vomit norovirus (abstract is here).

A pdf of the vomit cleanup food safety infosheet can be found here.

"Refusing to make listeria test results public, and saying Maple Leaf is doing what CFIA expects of the company, leaves Canadians blindly trusting the two groups under whose watch 20 people died. It's not particularly reassuring.”

That’s what I said in the Toronto Star this morning in response to Robert Cribb’s story yesterday that four months before the Maple Leaf outbreak started claiming lives, Canada's food safety agency quietly dropped its rule requiring meat-processing companies to alert the agency about listeria-tainted meat.

Neither Maple Leaf nor the safety agency will release to the public the specifics of the listeria outbreak at the plant, so it is not possible to determine how the reporting rule would have affected the case.

One Toronto inspector said there had been a "trend" in positive listeria tests leading up to the outbreak that was never reported by the plant to federal inspectors. The inspector, and three others across the country, spoke on condition of anonymity because they fear disciplinary action if they spoke publicly. "There's something wrong, that an inspector isn't aware of a trend in their own plant," the inspector said.

That does not mean more inspectors. As Karen Selick, a lawyer in Belleville, Ont., wrote in the National Post yesterday, the recent listeriosis outbreak has produced a predictable chorus of accusations from big-government fans attempting to pin the blame on the alleged deregulation of Canada’s food safety system

There was a full-time government inspector on site in every Maple Leaf  plant, but the listeriosis outbreak happened anyhow. Would additional government inspectors have prevented the problem?  Probably not. 

Back to the Toronto Star, where Maple Leaf spokesperson Linda Smith said her company makes all of its paperwork and testing available to inspectors but doesn't alert them to positive test results.

"As per the regulations, there is no requirement to inform the CFIA about any listeria test result," she said. "The protocol Maple Leaf had in place was if they found a positive, they would sanitize the area and then you'd need to find three negatives in a row to leave that area alone. In (the Maple Leaf plant from which the outbreak was traced), there were occasional positives. ... They would sanitize and test three subsequent times and in all of those cases, they did not find another positive in that area."

During the outbreak, Maple Leaf president Michael McCain said the company tests the Toronto plant's surfaces 3,000 times a year.

"Positive results for listeria inside a food plant are common," he told reporters at the time, adding that "there was nothing out of the norm" leading up to the outbreak.

Asked for the listeria test results leading up to the outbreak, Smith said last week the company would not release them publicly.

I used to steal toilet paper.

As an undergraduate 25 years ago, and once my girlfriend showed me how to get at the theft-proof rolls in the university centre, the supplies of toilet paper in our household became one less student expense.

My hockey bag is still filled with those little soaps and shampoos from hotel rooms around the globe.

I was the kind of student -- and apparently I'm not alone -- University of Guelph administrators in Canada were worried about when they said that residence students should provide their own handwashing soap.

In 2005, the university switched to sanitizers instead of soap and paper towels in the residence washrooms because soap dispensers, paper towels and garbage cans went missing.

That was before a 2006 norovirus outbreak sickened over 150 students, primarily in one university residence.

The university subsequently returned soap and paper towels to all residences to help control the outbreak.

Students at Georgetown University are now being implored to wash their hands after a norovoirus outbreak linked to the school’s dining hall caused 175 students to vomit their way to the hospital. Said one university official, “Handwashing is going to be our mantra for a very long time around here.”

That’s great. A little late, but better than before. The U.S. Centers for Disease Control and Prevention estimates that up to 25 per cent of the 76 million annual cases of foodborne illness in the U.S. could be eliminated with proper handwashing.

That's a lot fewer sick people.

But, as Jon Stewart quipped in 2002, “If you think the 10 commandments being posted in a school is going to change behavior of children, then you think ‘Employees Must Wash Hands’ is keeping the piss out of your happy meals. It's not.”

So why don't more people wash their hands?

While some practice a Howard Hughes-like paranoia, study after study shows that many are lazy when it comes to handwashing. The proclamations to practice proper handwashing, on restroom posters, in daycare facilities, in media scare stories, will always fail to register with those who are impervious to risk -- that bad things happen to someone else, not me.

But as the Guelph example demonstrates, anything that can even slightly encourage proper handwashing and hygiene in general needs to be encouraged -- and that means ready availability of soap, water and paper towels.

Once available, the facilities have to actually be used, whether in the workplace, the home, the university residence, or, the farm.

The steps in proper handwashing, as concluded from the preponderance of available evidence, are:

• wet hands with water;
• use enough soap to build a good lather;
• scrub hands vigorously, creating friction and reaching all areas of the fingers and hands for at least 10 seconds to loosen pathogens on the fingers and hands;
• rinse hands with thorough amounts of water while continuing to rub hands; and,
• dry hands with paper towel.

Water temperature is not a critical factor -- water hot enough to kill dangerous bacteria and viruses would scald hands -- so use whatever is comfortable.

The friction from rubbing hands with paper towels helps remove additional bacteria and viruses.
The next time you visit a bathroom that is missing soap, water or paper towels, let someone in charge know. And next time you see someone skip out on the suds in the bathroom, look at them and say, “Dude, wash your hands!”

Don’t eat poop.

Todd A. Olson

, vice president for student affairs at Georgetown University issued a statement this afternoon identifying norovirus as the cause of the recent gastrointestinal illnesses affecting Georgetown students and outlining a bunch of preventative measures. It was boring, and of course, didn’t say sorry for all the barfing.

However, the reporters at the Georgetown Voice offered a more entertaining presentation of the same information:

“Georgetown just sent out a message saying that the food poisoning is caused by the Norovirus, a contagious virus spread through oral and fecal contact. Georgetown is going to start a big cleaning regimen:

“Immediately, student residence halls are being cleaned with a specific focus on common areas and high contact surfaces such as bathrooms, doorknobs, and handrails. Common gathering areas including Yates Field House, McDonough Arena, the Leavey Center will also be cleaned, as well as bathrooms and high contact surfaces in academic and administrative buildings.

“It’s also spread by hand-to-hand contact. In June, a health inspection found that Leo’s had inadequate handwashing facilities for employees. According to the report, that problem was resolved. Georgetown says it’s going to continue normal operation, with a focus on cleaning. The message also encourages everyone to frequently wash their hands.

UPDATES: Todd Olson says the new number is 175 students. Only 3 in emergency room, 2 in student health center.
    Leo’s is open tonight.
    Any student who has missed class or assignment from being sick will be excused. Get in touch with your dean.
    Georgetown’s setting up a call center for parents. 1-800-208-5167. I guess it’s for calling to complain that your student is sick or could’ve been. For families with sick students: 202-444-3895
    Dr. Timpone is up saying everyone should wash their hands. Norovirus causes all kinds of miserable nausea, abdominal pain, diarrhea.
    People whose roommates have the virus and got splashed with vomit can easily get sick. Clean up! Use bleach.
    Degioia’s here! Timpone says don’t be upset if you get sick, the disease will pass in a few days. Just stay hydrated.
    I’m kind of surprised DeGioia’s here, considering how awful students were treated last night at that Grill.
    Question and answer time! Olson says he’s not familiar with the possible Leo’s handwashing connection. No word on whether you get to skip midterms, talk to your dean.
    Someone from Solidarity is asking about employees getting sick, good point. Todd says he doesn’t think any workers got sick.
    Todd says we’re getting lot of Powerade and hand sanitizers!
    Students who have vomit damage in their room  should call work management at 202-687-3432. I guess they’ll help now, unlike yesterday.
    People who have already been infected won’t catch it again.

Telling people to wash their hands is standard. Georgetown students, are there adequate supplies in the bathrooms – soap, water and paper towels – and were there adequate supplies before the outbreak?

Ever notice someone sick and working at Leo’s? That’s how norovirus often spreads, especially through a bunch of foods from one spot.

There are some tips on the infosheet below. Norovirus outbreaks like this are far too common.

In 2002, Jon Stewart quipped while hosting Saturday Night Live,

“If you think the 10 commandments being posted in a school is going to change behavior of children, then you think “Employees Must Wash Hands” is keeping the piss out of your happy meals. It's not.”

Apparently the signs aren’t working in Ontario hospitals either.

Jim McCarter, the province's auditor general, said in a report tabled in the provincial legislature that the results of a hand-hygiene program piloted in 10 hospitals revealed personnel were complying with the rules of good hand hygiene only 40 to 75 per cent of the time.

Time for new messages.

Toronto’s Globe and Mail newspaper reported Saturday that health officials in Ontario ordered hospitals and nursing homes to stop serving Maple Leaf meats five days before the public was told about a deadly source of food poisoning that has so far claimed 19 lives and left another 60 people seriously ill across Canada.

The CFIA launched its investigation on Aug. 6, after officials at the Ontario Ministry of Health informed it that there was an outbreak of listeriosis in the province. Many local health officials were already grappling with a spike in listeriosis cases, but they did not become aware that the outbreak spanned several provinces until July 30, when they received a directive from the ministry, telling them to urgently report any new cases.

On Aug. 14, health officials in Ontario learned during a telephone conference call with the CFIA that the agency had some test results revealing that Maple Leaf deli meats contained the foodborne bacteria known as Listeria monocytogenes.

The CFIA waited until it had the DNA fingerprint evidence establishing a definitive link before it went public – on Aug. 19, 2008.

CFIA spokesman Garfield Balsom said,

“We had lab results indicating that there was positive listeria in a product and we would issue our normal recall based on that.”

So epidemiology doesn’t count? If CFIA really does not issue public advisories unless it has a positive result, that would explain the low number outbreaks linked to fresh fruits in vegetables in Canada. Who knows how many sick people there are, and how many illnesses and deaths could have been prevented in the current listeriosis outbreak.

A positive listeria sample would have triggered an immediate recall in the U.S. So what is the CFIA policy on going public – on issuing advisories that specific foods may pose an imminent danger to the health of Canadians. CFIA won’t say what their policy is, at least not publicly, but a policy that maligns epidemiology and relies excessively on positive test results – especially when those samples appear to be delivered by stagecoach – is restrictive and reckless.

As past of that accountability, I told the Toronto Star on Thursday that Canada does not need an inquiry and does not need more inspectors, rather,

"People need to do their jobs. The CFIA is accountable to Parliament through the minister of agriculture, so either the minister, or the Prime Minister's Office, should call the head of CFIA on the carpet and say, `You've had this internal report since 2005. Issue some clear guidelines on how to communicate during an outbreak of food-borne illness. Give clear instructions to inspectors and the industry on what is expected to ensure a safe food supply ... If you can't do that, I will find someone else who can – and not some political appointment, someone with a food safety background who will do what is necessary to protect the safety of the Canadian food supply and bolster the Canadian brand in international circles.'"

Such straight talk, especially when it comes to informing the public about health risks, is largely missing in Canada, experts agree.

So while the politicians and unionists pontificate, a columnist at the University of Calgary student paper got the most rightest:

"Canadians have entrusted one single agency, the CFIA, to protect the entire Canadian food supply-- we have placed all food security in one basket.

"If the CFIA did not exist, perhaps Canadians would be better off. … The current food inspection system has failed Canadians. Maybe it is time for a change."

As an aside, a columnist with the Ottawa Citizen who fancies himself as some sort of risk guru wrote Saturday that,

“Another clue lies in the number of listeriosis deaths in past years. According to Statistics Canada, there were five in 2000. In 2001, four. In 2002, seven. In 2003, three. In 2004, one. (Data for subsequent years were unavailable.) …

“The Globe also noted the Canadian regulatory standard is weaker than that of the United States, which allows no listeria content at all in ready-to-eat foods. But the Globe did not report that, according to the Centers for Disease Control, roughly 2,500 Americans become seriously ill with listeriosis each year and 500 die.

“Thus the listeriosis fatality rate is far smaller in Canada than the U.S. That, too, does not suggest a crisis.”

The columnist is comparing actual listeria cases in Canada with estimated cases in the U.S. And why no alarm that the most recent numbers in Canada are from 2004?

Some of you may remember the 2004 International Association for Food Protection meting in Phoenix. At a local supermarket I found this sanitizing system for shopping carts displayed prominently. That’s when I started to think, maybe food safety can be marketed.

A few months later and I was in the Gold Coast, Australia, for a food safety meeting. I told one journalist about this new trend I’d observed –always gotta be trendspotting – of more prominent use of sanitizers in grocery stores.

That turned into,

“Doug Powell, a food safety expert from Canada, says a decision to put hand wipes in supermarkets and provide sanitising towels for shopping trollies has been successful in reducing the number of food poisoning cases in the US and Canada.”

And it ran all over Australia.

So I wrote a letter which was published in the Sydney Morning Herald and read in part,

“The use of hand wipes in supermarkets and sanitizing towels for shopping carts has been experimental at best in the U.S., and has not and cannot be correlated with any reduction in foodborne illness (Shoppers urged to clean hands to wipe out food-borne diseases, October 11/04, Sydney Morning Herald).

“However, as the Food Safety Information Council correctly noted, and as I stressed during the interview, any measure -- whether on the farm, in processing, at food service, in the home, and yes, at retail -- that can enhance food safety awareness should be explored and encouraged.”

Now it appears some such work has been done.

USA Today reports today that supermarkets and other retailers that provide shopping carts are increasingly looking to limit germ exposure for customers and their families.

“A ShopRite supermarket in Passaic, N.J., installed a push-through cleaning machine on Tuesday that sprays each shopping cart between uses with a misty peroxide solution to kill bacteria, according to Jim Kratowicz, president of PureCart Systems, the manufacturer of the machine. …

“Studies conducted in 2006 and 2007 by FoodNet found riding in a shopping cart beside meat and poultry is risky for infants under six months.

“Doing so triples the chance they may contract salmonella and quadruples it for campylobacter, a diarrhea illness, according to Olga Henao, an epidemiologist for the CDC.

“Infants can become ill when they transfer bacteria from the packaging into their mouths, Henao said. Also, if raw juices leak out onto the cart, it can create a bacteria risk for the next infant in the cart, she said.”

Trendspotting is just so hip. Here’s Demetri Martin with his own trendspotting.

I'm a self-described food safety nerd. I don't hide from this obsession, I embrace it.  But my fixation on everything food safety has led to much stress lately -- for the past 9 months my food safety spidey-sense has been heightened more than normal as Dani and I have been expecting a baby.

And he finally arrived last week.

Our little dude, Jack Neil Chapman, showed up Friday morning at 4:11am (Yes, the Neil part is named after the greatest Canadian singer/songwriter, Neil Young -- I'll fight anyone who disagrees, Ari Gold style, http://www.youtube.com/watch?v=QGVoLsDS3t8&e)

Throughout Dani's pregnancy I became the food police in our house -- no soft cheeses or cold deli meats made it to Dani's plate, most didn't even make it in the house. Everything (and I mean everything) has been temped during cooking. I read pretty well every paper I could on listeria, and Doug and I discussed the merits of broad food surveys and listeria growth in blue-veined cheese. It was a bit ridiculous, but I hear that first time parents sometimes can be obsessive.

During the recent Canadian listeria outbreaks I selfishly felt vindicated for keeping the products out of our house -- our view was that no matter what type of food safety system food processors had, we weren't taking the risk. Maple Leaf is a huge company that can afford lots of food safety controls, spoke about their commitment to food safety, and even used the food safety culture term Doug and I are so fond of. But 18 people have so far died from listeria in their products.

When I held Jack for the first time, about 30 seconds after he was born, I first thought "Wow, you're tiny and light, and you don't smell as manky as I had thought you would" and soon after I thought about the parents, people just like us, who have been recently affected by listeria.  The victims include at least one miscarriage and  six babies born prematurely in Quebec resulting from the consumption of soft cheeses. A 6-week old Manitoba infant born with a listeria, not linked to either Maple Leaf or Quebec soft cheeses outbreak, also died last week. Those are the ones we know about.

And then I realized that, although I thought I did a great job managing risks in our house, I and the rest of the food safety world have probably failed many out there who haven't reduced risks.  Not the individuals who made the choice to eat risky foods, but the parents who have never heard about listeria, the ones who ate risky foods without knowing that listeria is 20 times more likely to infect pregnant women or that listeria infections during preganancy are likely to cause miscarriages or stillbirth.   Who knows what effect our risk-reduction practices had on Dani's pregnancy. Maybe things would have been fine without being so strict, but we weren't interested in taking the chance.

I'm all about informed decisions around risk. I even think there is a place for raw milk consumption for adults.  But we had the info to make the decisions.  Info that came from a variety of places (for us it was primary resources, outbreak reports and review papers). Other parents rely on food safety professionals, like the health authorities, for info.

Last weekend was all about Jack, and I didn't get back into reading FSNet until yesterday morning (I'm getting quite good at holding him and reading emails at the same time) and I came across Canada’s Chief Public Health Officer, Dr. David Butler-Jones’ advice concerning listeria, including the below:
*Wash your hands. This will help avoid many kinds of infections. Wash your hands in warm soapy water before preparing food, afterwards, and again before eating.
*Read labels and follow cooking and storage instructions for all foods. Make sure to check the “best before” date.
*Freeze or consume leftovers within four days of cooking. Always reheat leftovers until steaming hot before eating.
*Keep refrigerators clean and at a temperature below 4 C, or 40 F. Listeria can grow in the fridge, but the colder it is, the slower it grows. Install a thermometer in your fridge to be sure.
Those tips apply to all of us, all the time, and not just during an outbreak.

There are so many holes in his list of advice, many have nothing to do with listeria, and I don't think there is evidence that supports many of his statements. Following the list of consumer blames, Butler-Jones did get into listeria with feel-good language: "For seniors, pregnant women, and those with weakened immune systems, or for those serving or caring for anyone in these groups, some extra precautions are very important as [various] foods pose some risk."  He ended his advice with "these steps form a simple approach to food safety."

The most important message missing from his list was: Don't eat this stuff unless you are cool with the risks.

I sent an email to Doug (the subject line was "what a f*ing joke"), saying where was Dr. Butler-Jones when the outbreak was announced a month ago.  Did it really take a month for his staff to wake up and get some info out there?  A question echoed in the upcoming Canadian Medical Association Journal which says that the Public Health Agency of Canada should be the primary source of information for the public during a crisis and that Canada's chief public health officer has not been the lead voice to inform the public.

So I guess my preachy message is along the lines of don't eat poop (especially baby poop, though Jack's hasn't started to smell yet).We need to do a better job of creating a dialogue around food safety risks with specific target audiences -- especially those at higher risk for foodborne illnesses.  And though the bureaucrats talk a lot, they need to be the real leaders in information -- and forget about the fuzzy language that will make the minister happy.  Tell people to stay away from the risky stuff.

If Canadian cattle or chickens get sick, the public is told all about it.

If Canadian people get sick, not so much.

That’s what I wrote in Dec. 2006 in a piece called, Sorry, bureaucrats just aren’t that into you.

I’ve said the same thing for the past month as the listeria in Canadian cold-cuts outbreak became public. The latest figures show at least 18 dead and 60 confirmed or suspected ill.

The several-week delay in telling Canadians about listeria in Maple Leaf cold-cuts, coupled with the self-congratulatory and exceedingly false statements about the superiority of Canadian disease surveillance is just another episode in the arrogant and dysfunctional father-knows-best approach to providing health advice practiced by various Canadian authorities.

Dr. Phil would say the relationship between officials at the Canadian Food Inspection Agency (CFIA) and the Canadian public is like a couple headed for divorce: they don't speak unless forced to, and when asked, it's denial, deceit and deception.

Rob Cribb of the Toronto Star reports today that a major review of Canada's food recall system three years ago identified serious problems that experts say continue to threaten public safety.

“Spotty inspections across the country, delays in warning the public about tainted food and a lack of follow-up to prevent repeat outbreaks are documented in the government report, obtained through access to information legislation.

The 2005 Canadian Food Inspection Agency (CFIA) review predicts concerns that have emerged from the current Maple Leaf listeria outbreak that has claimed 18 lives.

"There is no clear policy on when a recall requires public warning," the report states.

Timely public disclosure of food risks re-emerged as an issue last month when it took three weeks for officials to warn the public of tainted Maple Leaf meat. …

In the aftermath of the outbreak, public health officials and politicians were quick to reassure Canadians that the country has one of the best food safety systems in the world. But behind the scenes, the review documents a history of serious internal concerns: "Most findings in this report have previously been identified by the various parties involved in food recalls."

The CFIA audit paints a picture of a sometimes-chaotic system where turf wars can impact the public's need to know about food warnings. …

Doug Powell, a Canadian food safety expert working at Kansas State University, said any warnings officials received from the review appear to have been ignored. "It's contentment with mediocrity. The bureaucrats don't seem to care very much. They all talk a good game, but they never think it will happen to them, so they just go on."

I can imagine Dr. Phil asking in his Texas drawl "How's that working out for ya’ll?"

The most frustrating part is that CFIA is staffed with individuals who are excellent public advocates and spokespeople. On issues relating to mad cow disease or avian influenza, CFIA goes out of its way to communicate with Canadians, perhaps fearing that any crisis of confidence will reduce sales and impact Canadian farms.


Yet when it comes to the 11 to 13 million foodborne illnesses in Canada each and every year, CFIA has adopted a policy of don't ask, don't tell. 
Maybe Dr. Phil can get the public and CFIA into a relationship based on open communication, trust, and respect, but I doubt it. Time to move on.

That’s the name of an exhibit set to open yesterday at the South Florida Science Museum and expected to topple previous attendance records.

The Palm Beach Post reports The exhibition is based on a series of books by science teacher Sylvia Branzei whose research found that the average person swallows a quart of snot per day.

Other features of the exhibit include:

• guess the correct sequence of events that sets off barfing at the Vomit Center;

• match horrible odors to their correct source at Y U Stink;

• learn how vibrations of skin around the anus create a fart sound at Toot Toot; and,

• scale a 12-foot wall of pimples, warts and other skin blemishes.

Jennifer Cooper, a science educator at the museum, said,

"This is kind of a learning-in-disguise exhibit. They're learning without feeling like they're learning."

And you wonder why we call it barfblog.

A new report shows that of the 78 residents of the Canadian province of British Columbia who contracted listeriosis in the past six years, 10 per cent were pregnant women whose infections put them at high risk of miscarriage or stillbirth.

The majority -- nearly 60 per cent -- of pregnant women diagnosed with listeriosis either miscarry or have stillbirths.

In a case described in the current B.C. Medical Journal, a pregnant woman in her 30s went to a Lower Mainland hospital complaining of a stiff neck, fever, back pain and headache. After arriving, she delivered a stillborn baby at 21 weeks gestation.

The authors wrote,

"Health care providers [want] better information for themselves and resources they could share with pregnant women. … The information provided to pregnant women by health care providers needs to be targeted and clear," and that as a result of the spring survey, BCCDC will start a project to better inform health care providers and their patients about food safety risks during pregnancy.

It’s a national embarrassment that statistics on listeriosis in Canada are either not available or hopelessly unreliable. Further, the call to action probably never would have gotten noticed were it not for the 24 deaths and dozens of illnesses in the Maple Leaf listeria outbreak. Pregnant women and other at-risk populations deserve better.

Three weeks after the Maple Leaf financial dude told the markets the plant would reopen, the Maple Leaf listeria plant is about to reopen and produce deli-meats.

The company has videos, a long list of food safety enhancements they are adopting, and has created the position of 'chief food safety officer.'

Guess I thought a $5 billion a year company would already have one of those. But that’s one of the things I find most challenging – how to compel everyone from maintenance crews to CEOs that food safety matters, especially in the absence of an outbreak. Now there’s an outbreak, 24 suspected or confirmed dead, 56 ill.

"Throughout this incident we have steadfastly placed consumers' interests first" said Michael McCain, president and CEO of Maple Leaf Foods.

That remains to be seen as more is uncovered about why there were delays and lousy notification as news of the outbreak initially trickled out. But yes, once the problem became publicly apparent, the company acted in great fashion.

The Canadian Medical Association Journal yesterday called for a full public inquiry. Not necessary, and a waste of taxpayers money. A few Bill Marler lawsuits would reveal far more about who knew what when.

Or people could do their jobs:

• Maple Leaf in conjunction with the various public authorities should provide a full public accounting of who knew what when and what was done to find out more;

• some sort of warning system about the risk of listeriosis in foods must be developed for at-risk populations – especially pregnant women and the elderly because they are the ones who get sick and die; and,

• make all data of listeria testing in plants public so others in the industry can improve and consumer confidence can be enhanced with data not just words.

With Kansas State taking on Louisville tonight on ESPN2, it seemed like an apt moment to mention the hit heard round the Internet.

As recounted in the Washington Post:

“Kevin Barnes was best known as a slender fifth-year senior who had a penchant for missing tackles last season in Maryland's defensive backfield. When the weekend ended, Barnes was known in select circles only as the player who delivered a hit so hard it made someone throw up.

“How that happened is a testament to the power of the Internet, where Barnes's image will long live because of five seconds of football that resulted in considerable, if not typical, notoriety. When he crashed his shoulder into the chest of California running back Jahvid Best in the second quarter of Maryland's 35-27 victory, Barnes had no idea he soon would be entering cyberspace lore.

Nor did he realize the magnitude of the hit when he saw Best crawling on knees and hands and vomiting on the field.”

Barnes may even have a future as a food safety risk communicator:

"He's not permanently hurt, so I'm fine with that. Had he died or something, I'd have felt bad, but he'll probably be playing next week."

Or not.
