O157

    Albert Amgar provided this story from Agence France-Presse about an E. coli O157:H7 beef recall, Nikki Marcotte translated, Amy Hubbell proofed and I embellished.

    At least this French company is suggesting a temperature, but doesn’t say how that is to accomplished in a hamburger patty. And while thorough cooking to the appropriate temperature (the. U.S. says 160) will destroy the bad bugs, cross-contamination in any kitchen – home, food service, retail – is a huge issue and difficult to control. Here’s the story.

    It was announced Friday that the Covial company, which specializes in ground and vacuum-packed beef, is recalling batches of hamburger and fresh ground beef sold in Carrefour et Casino stores under their own label due to a risk of food poisoning.

    The products have been removed from the shelves; consumers have been asked not to eat these products in which the bacteria E. Coli O157:H7 was detected during a self-check, said Covial in a statement. To date, no consumer complaints have been reported, the statement said.

    The recall affects 3.8 tons of products that have been sold in the Carrefour stores, Carrefour Market, Carrefour City, Carrefour Contact, Shopi, 8 À Huit, Marché Plus, Géant Casino and Casino supermarkets, according to the source.

    The batches bear the following inspection stamp: FR 15 014 032 CE. The products’ expiration dates are July 6th and 7th for the Carrefour batches and July 7th for the Casino batches.

    Those affected, for Carrefour, are the Aquitaine, Auvergne, Bourgogne, Centre, Franche-Comté, Haut-Rhin, Languedoc-Roussillon, Limousin, Midi-Pyrénées, Poitou-Charentes et Rhône-Alpes regions. For Casino, the center and the southwest quarter of the country are concerned.

    Thoroughly cooking the hamburgers helps prevent the consequences of a contamination of this type, the bacteria is destroyed at 65°C (149 F). The E. coli O157:H7 bacteria can cause symptoms such as gastroenteritis, sometimes accompanied by a fever, within 10 days following the consumption of the contaminated hamburgers.

    In rare cases, poisoning can be followed by severe kidney complications in children and in the elderly. Consumers can call 0805 803 134 (free from a land line).

    The Palm Beach Post reports this morning that Amber Dycus, 38, of Loxahatchee, Florida, went to the hospital after four days of illness. The doctors told her she was in acute kidney failure, hours from death. She endured six days of intensive care, multiple blood transfusions and, so far, 196 bags of plasma.

    There are more treatments to come, and no signs yet that her kidney function is approaching normal. She feels lucky to be alive, but also very afraid - afraid of eating out, afraid of catching germs, afraid of never getting better.

    Dycus desperately wants to know what did this to her. Her lawyer, Craig Goldenfarb, thinks the public ought to feel the same way.

    A health department inquiry has resulted in the brief closure of a Royal Palm Beach restaurant where Dycus often ate. Inspectors found roaches, improper food temperatures, slime in the freezer and a dishwasher with almost no sanitizer in it. After a thorough cleaning and a tuneup on the dishwasher, the restaurant, Hilary & Sons, has reopened.

    But was it really the source of her illness? A series of missed opportunities, miscommunications, delays, and no small measure of scientific uncertainty means there may never be a conclusive answer.

    At Palms West last month, Dycus was diagnosed with hemolytic-uremic syndrome. It's an often fatal condition that happens when toxins cause red blood cells to shear apart and clog capillaries, shutting down the kidneys and leading to a buildup of waste in the blood.

    It's associated with outbreaks of dangerous E.coli O157 food poisoning.

    Normally, when E.coli O157 is suspected, the health department is notified immediately, so that a public health investigation can be launched.

    Dycus said her doctors told her she must have eaten contaminated beef. She's grateful to them, and the nurses at Palms West, whom she says saved her life. But one thing they did not do was notify health authorities. A spokeswoman for Palms West said she could not comment.

    It wasn't until Dycus contacted a lawyer, and her lawyer called the media, that a health inquiry began. By then, a month had passed, the foods Dycus had eaten had long since disappeared, and the ability to tell exactly what sickened her had become nearly impossible to discern.

    Amy’s anxious.

    For the first time in Sorenne’s 16 months, Amy is going away for a couple of days, leaving me and the kid to par--ty.

    Amy and a colleague left early this morning for Montreal and the Northeast Modern Language Association annual meeting, or NeMLA. Every time she says NeMLA, I say NAMBLA. It never gets old.

    I was chatting with the neighbors yesterday about how fortunate we are. We have two students provide 20 hours of child care for Sorenne – the most loved child in the world – in our house. And contrary to the expectations, Sorenne is exceedingly social. If we wanted 20 hours of day care, we’d have to pay for 40 – full-time. The U.S. has some weirdness, like 6 weeks of maternity leave. We’re fortunate.

    Not so the kids at a day care center in Clark County, Washington, which has been temporarily shut down after four kids were hospitalized with E. coli O157:H7.

    The Oregonian cited Dr. Alan Melnick, Clark County's public health officer, as saying the health department learned of the first hospitalization on March 19. Soon after, three other children required hospitalization. Investigators tested stool samples from 22 children and four adult caregivers at the day care and found six carrying the O157:H7 strain but not showing symptoms.

    The day care will remain closed until the affected staff show no presence of the bacteria on two consecutive tests conducted at least a day apart, Melnick said. Children who tested positive have to meet the same criteria before being allowed to attend any daycare or school.

    Who knows what goes on in these petting zoos in the U.K., Canada or the U.S., but it appears to be a mess. That’s why kids get sick every year.

    A feature in tomorrow’s (today’s) Sunday Times alleges that E. coli O157 was found at a popular children’s petting zoo where dead animals were openly left to rot for weeks.

    An undercover reporter who spent several weeks working as a volunteer at the unlicensed zoo discovered:

    - Corpses of animals left to decompose near where visiting children play.

    - Staff alternating between working with the animals and helping out in the visitors’ cafe, wearing the same clothes and shoes.

    - Cafe food stored next to dirty parrot cages.

    - No hot water for handwashing except in the cafe kitchen. One worker said there had been no hot water in the toilets for five years.

    - Animals suffering with painful diseases and fed inappropriate food such as chocolate, lollipops and marshmallows.

    -A swab taken from the faeces of a pig in a petting area showed E coli O157 in laboratory tests.

    Last year several outbreaks at petting zoos across Britain caused a number of children to require medical treatment.

    Tweddle Children’s Animal Farm, which opened in Blackhall Colliery, Co Durham, five years ago, is open seven days a week, all year round, and offers family season tickets to encourage repeat visits. Its website claims it is “bursting with animal fantasticness [sic].”

    The farm has a range of exotic animals, such as monkeys, ostriches, buffalo, camels and lemurs. Yet it has no zoo licence, which is a legal requirement. Only regularly inspected zoos can have a licence.

    The owners, Denise and Peter Wayman, could now be prosecuted under the Zoo Licensing Act and possibly under the Animal Welfare Act.

    I don’t know what it is with baby nurseries and what I guess Americans would call daycare for the older kids in the U.K., but there are way too many outbreaks of E. coli O157.

    The Hounslow Chronicle reports that as many as 25 pupils at Feltham Hill Infant & Nursery School are believed to have been infected by the E. coli bug.

    A spokeswoman for the Health Protection Agency today said there were now five confirmed cases of the O157 strain, with another seven presumed positive and 13 'symptomatic' cases, which are still being investigated. She could not confirm whether everyone who had been infected was a pupil at the school in Bedfont Road.

    Today, it was reported that a second nursery in Feltham has closed following a suspected outbreak of E. coli.

    Once Upon a Time Nursery, in Ashford Road, closed on Friday after 11 children suffered diarrhoea and vomiting, which are symptoms of the infection.

    A spokeswoman for the HPA said it was too early to say whether the infection is related to the E. coli outbreak or is an outbreak of norovirus, which has similar symptoms and is common at this time of the year.

    Mum-of-two Nina McLaren and her best friend Jodie Davies, both from Flint, became seriously ill after spending four days in the Spanish  resort of Benidorm last month.

    In total, 14 holidaymakers contracted E.coli O157 after  stays in Benidorm during November.

    Now travel lawyers at Irwin Mitchell, along with the Health Protection Agency, have launched an investigation into the source of the bacteria.

    27-year-old Jodie told the Daily Post:

    “The whole ordeal has been so distressing and painful that I really do wish we had never gone on holiday at all, it feels like we haven’t had one.  … To learn that there were so many other people that fell ill with the same thing is a real worry. I wouldn’t wish it on anyone so it’s a relief to hear that there is an investigation into where the source was.”

    I’ve been interviewed and quoted by Prevention magazine a few times about food safety stuff. They didn’t seem any worse or better than anyone else and I always took the time to explain things from my world of microbial food safety and what makes people barf.

    But their latest story, which did not include me or any other food safety expert I know, claims to present, The top 7 foods avoided by food safety experts.

    Greg Johnson, editor of the Kansas City-based The Packer went twitterlistic, writing that the "7 foods experts won't eat, from Prevention mag lists conventional apples and potatoes. Too bad "experts" are bunch of leftist hacks.”

    Not sure if it’s a left or right thing – the U.S. is big on moral dualism. Maybe it’s a dumb or smart thing.

    Liz Vaccariello, editor in chief of Prevention Magazine, recently interviewed several experts on food healthfulness and safety. She asked, “What foods do you avoid”, and was surprised by some of the answers.

    1. Canned Tomatoes, Canned Soup, Canned Green Beans

    Something to do with BPA. Risk is minimal. Canned tomatoes are a great source of antioxidants. Canned soup and green beans are great comfort food. Food safety is impeccable.

    2. Corn-Fed Beef

    Something to do with nutrient profiles and blowing Whole Foods. Corn-fed beef rocks.

     3. Microwave Popcorn???

    Something about the chemicals. Eat real food, not popcorn.


    4. Nonorganic Potatoes and Carrots???
    Something about root vegetables absorbing pesticides. I worry more about microorganisms, and eating enough fruits and vegetables.


    5. Farmed Salmon???
    Something about chemicals in farmed salmon, which are far below acceptable government limits. Farmed salmon preserves the environment.

    6. Milk Produced with Artificial Hormones???
    Something about rBST and this is the best someone at the Campaign for Safe Food at the Oregon Physicians for Social Responsibility can come up with, when 30 per cent of all people in all countries get sick from the food and water they consume each year, and none of it has anything to do with genetically engineered hormones.

    7. Nonorganic Apples and Pears???
    Something about pesticide accumulation. Total BS. Bring on the conventional apples and pears. My kid loves them.

    Today’s USA Today has a feature story today about meat served in the U.S. school lunch program and asks why certain batches of meat were excluded from a Salmonella-related recall and outbreak last year. What stands out is that the U.S. Department of Agriculture initially refused to match suppliers with positive test results as part of an analysis of 146,000 tests for bacteria including salmonella and E. coli.

    USDA spokesman Bobby Gravitz wrote in an e-mail to USA Today that divulging their identities "would discourage companies from contracting to supply product for the National School Lunch Program and hamper our ability to provide the safe and nutritious foods to America's school children."

    The newspaper appealed the USDA's decision. On Monday, the department released the names of the companies.


    Although one company, Beef Packers Inc., appeared to stand out for the wrong reasons – in 2007 and 2008, its rate of positive tests for salmonella measured almost twice the rate that's typical for the nation's best-performing, high-volume ground beef producers, USA TODAY found -- the company kept getting government business. Since 2003, Beef Packers has garnered almost $60 million in contracts.

    That sounds eerily familiar to what happened in the 2005 E. coli O157 outbreak in Wales that killed five-year-old Mason Jones (left) and sickened another 160 kids eating their school lunches, where buyers were quick to look the other way to save a pound. A public inquiry into the outbreak concluded the procurement process was, “seriously flawed in relation to food safety.”

    One way to push food safety through the system is to demand continuous improvement from suppliers in terms of lowering the number of pathogen positive results. Any consumer-oriented company is going to insist on evidence of such steps or they will take their business elsewhere. Those overseeing school lunches for U.S. kids should demand the same.

    What also stands out is that despite the focus on food safety of the feature and an additional heart-wrenching story about a child sickened 11 years ago through the school lunch program, a third story about a company trying to provide low-cost, healthier, natural (whatever that means) school lunches makes no mention of – food safety. The story cites a sample lunch that may now contain fresh lettuce and tomatoes in a wrap, rather than the canned or cooked variety of fruits and veggies. Fresh is great, but introduces an array of microbial food safety and supplier management issues that isn’t even mentioned. Sorta ironical.

    The U.K. Health Protection Agency is investigating a number of cases of the gastrointestinal infection E. coli O157 associated with travellers returning from the resort of Benidorm in Spain.

    So far the HPA has been made aware of 14 confirmed cases of E. coli O157 among travellers returning to the UK, with onset dates ranging from 12th - 21st November. All laboratory confirmed cases are adults. Four people are known to have been admitted to hospital after returning to the UK. Two have since been discharged.

    I’m sure the sick people will be relieved to know, “there are some simple measures that people visiting Benidorm can take to protect themselves and their families against this infection” like handwashing and avoiding food that has been cross-contaminated. Should the people be roaming the kitchens looking for cross-contamination?

    The Denver Post reports that exposure to animals at Denver's National Western Stock Show was the likely cause of an E. coli outbreak that occurred in the Denver area in January and February, the Colorado Department of Public Health and Environment said today.

    Specifically, contact with animals in the "Feed the Animals" exhibit on the third floor children's area of the exposition center was probably where the outbreak originated, according to the extensive 15-page report.

    A total of 30 cases were identified.

    Children were disproportionately affected in the outbreak, suggesting a source that children would likely have more contact with than adults.

    The report noted that the third floor children's area of the expo center had a variety of exhibits geared towards children, including pony rides, a playground area, cages housing rabbits and poultry, educational exhibits, and hands-on activities.

    In addition, food vendors were also located on the floor.

    One of the exhibits was the "Feed the Animals" exhibit, where calves, goats, lambs, pigs and other farm animals were brought in from private owners located throughout the region. …

    There were opportunities throughout the day for the visitors to feed the animals.

    While feeding the animals was not a risk for illness, touching them put the visitors at higher risk of developing E. coli infection.

    The investigators said that while hand sanitizer dispensers were readily available in the "Feed the Animals" area, and there were numerous signs instructing visitors to practice hand hygiene, the use of the sanitizers "was not protective against the illness."

    In addition, handwashing facilities with running water, soap and paper towels were not readily available in the area.

    There were no signs that warned that animals could cause disease or any that specifically cautioned against sipping from cups or eating or drinking in the animal contact areas as well as the use of strollers in that area.

    The investigators suggested that such signs be posted in the future.
