Lettuce linked to 36 ill in Michigan, 3 in Ontario, came from California
The Detroit Free Press is reporting that state agriculture officials say the tainted iceberg lettuce that has been linked to 36 E. coli O157:H7 illnesses in Michigan and 3 in Ontario originated in California before being shipped to Michigan.

Aunt Mid’s Produce of Detroit was identified as one of the local suppliers. The company immediately stopped its lettuce distribution, said Philip Riggio, chief executive officer, and had its supply and processing facilities tested by outside experts. The tests found no evidence of contamination.
The Michigan Department of Agriculture also tested Aunt Mid’s lettuce, with no findings of E. coli, but, “we never had product available that was tested from the outbreak timeframe, primarily due to the perishable nature of the product we dealt with,” said Jennifer Holton, MDA spokesperson.
A Michigan State University student sickened by E. coli-tainted lettuce is suing Aunt Mid’s. Samantha Steffen of East Lansing began suffering from bloody diarrhea and was hospitalized with dehydration in mid-September.
“At this point, based on testing…I don’t believe the lawsuit has any merit,” said Riggio.
Canadian food safety bureaucrats continue to stumble -- and more people are sick
I started FSnet, the food safety news, shortly after the Jack-in-the-Box outbreak in Jan. 1993. Sure, Al Gore hadn’t invented the Internet yet, but those of us in universities had access, and I started distributing food safety stories.
(1)(1).jpg)
It all seems sorta quaint now, what with Google alerts and blogs and RSS feeds, but my goal was straightforward: during the Jack-in-the-Box outbreak, a number of spokesthingies said, they didn’t know E. coli O157:H7 was a risk, they didn’t know that Washington State had raised its recommended final cooking temperature for ground beef, they didn’t know what was going on.
So FSnet was conceived and made widely available so that no one could legitimately say, they didn’t know.
Yet that’s exactly what federal bureaucrats in Canada said last night when questioned about the delay in warning those in southwestern Ontario that lettuce from Aunt Mid’s in Detroit, implicated in a large Michigan-based E. coli O57:H7 outbreak that has stricken at least 34, had made its way across the border.
And now at least two people in Ontario have tested positive for the same strain of E. coli O57:H7.
David Musyj, president and chief executive officer of the Windsor (Ontario) Regional Hospital, said last night that authorities in Michigan issued a public-health alert about the link to Aunt Mid’s iceberg on Friday, Sept. 26, 2008, but the Canadian Food Inspection Agency didn’t bother notifying Windsor health officials until Wednesday, Oct. 1, 2008.
"What happened between Sept. 26 and Oct. 1? Clearly there is a communication gap that occurred. I want an investigation to be launched into this to find out why there was a communication gap, whether it was our CFIA or whether it was the State of Michigan."
Dustin Pike, a spokesman for Agriculture Minister Gerry Ritz, said in an e-mail yesterday that the Public Health Agency of Canada notified the CFIA of the E. coli outbreak in Michigan potentially linked to the lettuce on Tuesday, and after determining that the product had been imported into Canada, the CFIA contacted Windsor health authorities the following morning. …
Davendra Sharma, a food-safety recall specialist at the CFIA, said the agency acted promptly when it heard of the outbreak to identify who in Canada purchased the product and to notify Windsor officials.
Again, I started FSnet all those years ago so bureaucrats and others couldn’t say, I didn’t know.

The Michigan outbreak was first publicly reported on Sept. 16, 2008. Lettuce was identified as the primary suspect on Friday, Sept. 26 2008. Why it took until Tuesday, Sept. 30, 2008 for someone at Health Canada, the Public Health Agency of Canada or the Canadian Food Inspection Agency to notice there was an outbreak next door in product that could be shipped to Canada is baffling.
Especially because of all the bureaucrats that read FSnet. According to tonight’s numbers, 27 people at PHAC, 149 people at Health Canada, and 316 people at CFIA receive FSnet. That’s almost 500 people, and no one noticed?
Tonight, test results have, unfortunately, revealed that two cases of E. coli O157:H7 in Chatham-Kent, Ontario, are of the same strain identified in 38 cases in the United States. All of the cases are thought to be linked to shredded iceberg lettuce distributed by Aunt Mid's Produce Company. This product is distributed in five pound industrial bags to institutions such as hospitals and long-term care homes, as well as restaurants in southwestern Ontario.
Musyj of the Windsor hospital captures the failings of CFIA when he says:
"Once something is thought of seriously enough to raise a red flag, then you better call everyone affected by the red flag. You can't wait for a death to happen to notify everyone."
Although that seems to have been the CFIA policy with listeria: with 20 dead and counting, it’s a bad policy.
CFIA, what is your policy on going public with information that can prevent illness? Is your primary priority to protect public health? If so, can you provide evidence to back such a claim?
And how can any of you say you didn’t know?
Oh, and for those who see salvation in a single food inspection agency, as is often discussed in the U.S., please notice the dysfunctional mess that is CFIA.
New food safety infosheet -- Lettuce linked to E. coli O157 outbreak
Last week, an outbreak of E. coli O157 in Michigan was linked to bagged, industrial-sized packages of iceberg lettuce distributed to institutions and restaurants throughout the state, according to Michigan's Department of Community Health (MDCH). 34 illnesses in Michigan have been linked to this outbreak, as well as illnesses in IL, OH, NY and OR. MDCH suggests that the outbreak is associated with eating lettuce at a facilities supplied by Aunt Mid's Produce Company, a Detroit-based wholesale distributor.
In a press release yesterday, Aunt Mid's Produce Company reported that they hired an outside laboratory to test products and samples from their facility, and that the results from the tests "prove there is NO CONTAMINATION in Aunt Mid's products."
Strong words, especially since the outbreak has been linked to products that were consumed between September 8 and 19.
This outbreak is the focus of the newest Food Safety Infosheet, and can be found here.
Lettuce linked to Michigan E. coli O157:H7 outbreak; MSU needs to check its food safety facts
On the same day that congressional investigators cited shoddy oversight of produce processing operations, wholesale, bagged iceberg lettuce appears to be the culprit in the Michigan E. coli O157:H7 outbreak that has sickened at least 26 people.
“Some of the 26 Michigan cases consumed shredded or chopped iceberg lettuce in restaurants or institutions purchased from Aunt Mid’s Produce Company, a Detroit-based wholesale distributor; and other distributing outlets could be identified. Product trace back and additional tests results are still in progress.

“Our top priority at the Michigan Department of Community Health is to protect the public,” said Dr. Gregory Holzman, chief medical executive for MDCH. “We appreciate all of the assistance from Aunt Mid’s. They have been very helpful in this investigation. We want to ensure that the public’s health and well-being is protected. Even though the investigation is ongoing, available evidence is strongly pointing to iceberg lettuce.”
Wouldn’t it be nice if just one public health official in Canada had a similar statement – our top priority is to protect public health – during the listeria outbreak that has killed at least 18?
Although I do have some concerns about statements from Michigan State University physician Beth Alexander, who tonight said,
“We will continue to be as cautious as possible, until this issue is completely resolved.”
This is the same MSU physician Beth Alexander who said on Sept 16, 2008,
“Generally, the infection isn’t serious. It’s usually caused by food or water that has been contaminated with that bacteria.”
The eight MSU students who were hospitalized probably thought it was serious.

Further, a press release from MSU tonight said,
“The one food item typically associated with E. coli outbreaks is undercooked hamburger. Health officials advise all chefs to cook their hamburgers until the juice runs clear.”
I’m not sure what that has to do with lettuce. And color is a lousy indicator for judging whether meat is done or not – a digital, tip-sensitive thermometer is a must. Cooking until the juices run clear seems reckless rather than cautious.
Alexander also stressed that thorough hand washing remains the most effective way of fighting communicable diseases, and,
“Always wash your hands before preparing any foods. Make sure your countertops are clean and don’t do any food preparation if you are sick.”
Again, I’m not sure what this has to do with lettuce. Doesn’t instill a lot of confidence in the ability of MSU food service to provide safe food – no matter how much Spartan spirit they have. Maybe MSU should be examining their food procurement policies. If this is what a top-10 land grant university produces, maybe those rankings don’t mean too much.

Strict safety guidelines enforced as produce travels from Mexico
“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
E. coli O157 outbreak in Sweden associated with locally produced lettuce
.jpg)
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.
Salmonella in tomato toll rises to 138; E. coli in lettuce outbreak appears over
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.
(1)(1).jpg)
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.
E. coli O157:H7, possibly in romaine lettuce, sickens 9 in Washington State
(1).jpg)
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.
Taco John's E. coli lettuce grown next to Calif. dairy farm

The report does not definitively state how the lettuce was contaminated but said water contaminated by manure from two nearby dairies could be a possible source.Wegis Ranch uses manure water to irrigate some fields where animal feed is grown, according to the report. It said lettuce linked to the E. coli outbreak was grown directly across from two of those fields.
In addition, the ranch’s irrigation system may have allowed manure water to taint freshwater used to irrigate fields where lettuce was grown, the report concluded.
E.coli samples from the ranch and dairies genetically matched the strain found in the tainted lettuce. The dairies were Maya and West Star North.
The next day, Bloomberg News reported that the U.S. Food and Drug Administration had published guidelines that suggested employees of fresh-cut fruit and vegetable processors wash their hands to help stop the spread of contamination.
Yes., handwashing is important. So is not growing fresh product in cow shit.
Don't eat poop.
Listeria found in lettuce at central Florida market
News from Orlando, where Amy and I arrived last night for some work and play, and where the Florida Department of Agriculture found traces of listeria on California lettuce at the Dr. Phillips Boulevard Fresh Market store in town.A Fresh Market release said, "We will continue to monitor the situation to ensure our stores are taking all necessary precautions."
Fresh Market shopper Lori Pinner said, "I really find it hard to believe. I have shopped here so much, and everything we have ever gotten has been really fresh. We've never gotten sick."
Shopper Robin Smith said, "You never know with anything. You just have to trust the store."
Canadian E. coli O157:H7 find prompts Dole to recall Hearts Delight salad in U.S.
.jpg)
Dole Fresh Vegetables is voluntarily recalling all salad bearing the label "Dole Hearts Delight" sold in the U.S. and Canada with a "best if used by (BIUB)" date of September 19, 2007, and a production code of "A24924A" or "A24924B" stamped on the package. The "best if use by (BIUB)" code date can be located in the upper right hand corner of the front of the bag. The salad was sold in plastic bags of 227 grams in Canada and one-half pound in the U.S., with UPC code 071430-01038.To date, Dole has received no reports that anyone has become sick from eating these products. The recall is occurring because a sample in a grocery store in Canada was found through random screening to contain E. coli O157:H7. No other Dole salad products are involved.
This product was sold in Ontario, Quebec and the Maritime Provinces in Canada and in Illinois, Indiana, Maine, Michigan, Mississippi, New York, Ohio, Pennsylvania, Tennessee and neighboring states in the U.S. Consumers can call the Dole Consumer Center toll-free at 800-356-3111. Consumers are reminded that products should not be consumed after the "best if used by" date.
Rene Cardinal, national manager of the fresh fruit and vegetable program at the Canadian Food Inspection Agency, told the Ottawa Citizen,
Don't play Russian roulette. If you have it in your home, destroy it," and that not all bags are necessarily contaminated, "but don't take any chances."
Marty Ordman, a Dole spokesman, told the Associated Press that the romaine, green leaf and butter lettuce hearts that went into the blend were grown in California, Colorado and Ohio, then processed at Dole's plant in Springfield, Ohio on Sept. 6.

California Senator Dean Florez, D-Shafter, chairman of the Senate Select Committee on Food-borne Illness called on the Secretary of the California Department of Food and Agriculture, A.G. Kawamura, to provide his office with details on the latest recall of leafy greens grown in the United States, and to inform the committee immediately whether or not the lettuce in question was grown in California and, if so, whether or not the grower was a signatory to the Leafy Greens Marketing Agreement proposed by industry as a self-regulatory approach to food safety.
Dole lettuce from U.S. found with E. coli O157:H7 in Canada
The Canadian Food Inspection Agency (CFIA) warned the Canadian public at about 2 a.m. Monday not to consume Dole brand Hearts Delight lettuce salad (Ready to eat blend of romaine, green leaf & butter lettuce hearts) because it may be contaminated with E. coli O157:H7, stating,"The affected product, Dole brand Hearts Delight lettuce salad (Ready to eat blend of romaine, green leaf & butter lettuce hearts), produce of USA, is sold in 227 g packages bearing UPC 0 71430 01038 9, BIUB (Best If Used By) date 07SE19 and lot code A24924B. This product may have been distributed nationally.
"There have been no reported illnesses associated with the consumption of this product."
The quotes above are from the third version of the press release sent out since early Monday morning. And since CFIA always holds information close, iFSN called CFIA and was told the contaminated product was detected during routine CFIA surveillance at retail. CFIA could not tell us where the sampled product was purchased, or where the lettuces were grown.
But it's local, it must be safe

Hawaii's Department of Health was cited as reporting earlier this month that four tourists and four others on Kaua'i in March were most likely infected by eating contaminated lettuce from a Kaua'i farm, where heavy rains and flooding had carried E. coli O157 from a cattle pasture onto the lettuce patch.The story notes that health investigators took DNA from the disease organisms in patients, and were able to determine that the strain of E. coli O157 bacteria in all the victims had the same DNA fingerprint.
Janice Okubo, public information officer for the state Department of Health, was quoted as saying,
"It was determined that one item, locally produced lettuce, was common to at least one restaurant eaten at by each case during their probable exposure."
