E. coli happens: cook burgers to 165F, whatever ruminant it came from

Seventeen years ago, Gregg Jesperson ate a burger that was still pink at a mom-and-pop restaurant in northern Alberta (that’s in Canada), where he and his family were living at the time.

The medication he’ll have to take for life is one reason why he’s not going to forget what happened anytime soon.

Jesperson, now a teacher at Booth Memorial in St. John’s, ate the burger on a Thursday.

By Sunday, it was determined Jesperson had developed hemolytic uremic syndrome, or hamburger disease.

Jesperson was hospitalized almost four weeks, undergoing dialysis and being hooked up to a machine that withdraws plasma and replaces it.

After his release, it took him almost a year to regain his physical strength.

Jesperson, who always enjoyed a rare steak, says he wasn’t aware of the dangers of uncooked hamburger meat before that.

“I’m a big fella, fairly hardy and that, and it really knocked the piss right out of me,” he says.

These days, Jesperson gets nervous when he sees people served burgers that are a little pink.

If he grills one himself, he “cooks the bejeezus out of it.”

His advice is to do the same, and not to be afraid to send undercooked burgers back at a restaurant.

Better advice would be to use a tip-sensitive digital thermometer because color is a lousy indicator of safety.

But this story is a lot better than the misguided letter-writer to a New Brunswick newspaper (also in Canada) who insisted dangerous E. coli like O157 only “grows inside of dairy and beef cattle that are fed a high proportion of grain.” Way to recycle a 15-year-old myth.

Dr. Oz says people can eat steak tartare but tells Margaret not to eat raw meat straight out of the package, Joy on the Foodtard Network is more concerned about creating grill marks on steaks than safety, especially cross-contamination, and Heston is a hero to most but norovirus-boy still don’t mean much to me.

UK grandmother dies from salmonella in sprouts Aug. 2010; inquest blames poor labeling guidelines?

The death of a Jewish grandmother who contracted salmonella from bean sprouts should force national changes to food labelling to prevent further deaths, a coroner has ruled.

A four-day inquest into the death of René Kwartz, from north Manchester, concluded that the 82- year-old was infected by salmonella, in bean sprouts served at a Jewish wedding in August 2010. It had been alleged that the wedding’s caterer, Shefa Mehadrin, had neglected food safety standards.

But on Dec. 8, 2011, the inquest’s jury unanimously returned a verdict of death by natural causes.

During evidence from Bury Council’s environmental health investigators, it emerged that no fault was found with the caterer, but that serving instructions on the bean sprout packages used at the wedding, were misleading.

Manchester Coroner Nigel Meadows said he would push the government and the Food Standards Agency to review cooking guidelines on bean sprout packaging. The agencies must report on what action will be taken within 56 days.

Concluding the inquest, Mr Meadows said: "It seems that clarity on the cooking of this product could be easily achieved.

Instant-read thermometers make people better cooks; lowers risk of killing family and friends with food

An instant-read thermometer is the best gift for the cook who has everything. Here’s what some folks told Elizabeth Weiss of USA Today.

William Keene, senior epidemiologist at Oregon’s Public Health Service, gives instant-read thermometers as wedding presents. "They save people’s lives."

The thermometer also makes Keene’s food taste a lot better. That’s because after spending a long day talking to people who’ve gotten sick from eating undercooked food, he found he had a tendency to overcook everything. Food "would get all dried out." But when he used the thermometer he actually stopped when it was done, rather than overdone. Though don’t forget to wash the tip with soapy water after you use it, "to avoid cross-contamination.”

Kathy Bernard of the U.S. Department of Agriculture’s Meat and Poultry Hotline gives them out as bridal shower presents. At the holidays they’re especially useful when people pull out recipes they don’t often make, like eggnog. "Since it contains raw eggs, if you’re going to make it from scratch you start cooking the egg base, stirring it over low heat until the mixture reaches 160," to kill any possible salmonella.

Jack Bishop of America’s Test Kitchen, a popular cooking show on PBS, said, "It’s something you can be pretty sure most people don’t own, or if they do own one, they don’t own a very good one.”

And they’re not just for meat, says Bishop. The old-fashioned method of knocking on the bottom of the loaf pan to see if the bread’s done only works if you’ve spent enough years baking bread that you know what you’re listening for. With a thermometer there’s no guessing. Plain bread is done at between 200 and 210, a sweet loaf between 190 and 200.

And for cheesecake, a thermometer is the key to avoiding cracks across the top. "The magic temperature is 150," Bishop says

Old-fashioned meat thermometers rely on metal actually expanding and turning the temperature dial. Digital instant-read thermometers use electronics and are faster and generally more accurate. The instant-read digitals use slightly different technology than a regular digital thermometer, so be sure to look for ones that say they are instant-read.

Our favorite is the Comark PDT 300 (right, exactly as shown, about $30).

I started using my thermometer on homemade bread a couple of years ago; big improvement.

We don’t need no education: burger preparation, what consumers say and do in the home

I cringe when someone says, ‘food safety is simple.’

A review of existing studies by the U.K. Food Standards Agency found that, although people “are often aware of good food hygiene practices, many people are failing to chill foods properly, aren’t following advice on food labels and aren’t sticking to simple hygiene practices that would help them avoid spreading harmful bacteria around their kitchens.”

Yes, individuals are impervious to risk; been known for decades.

And there’s that word, ‘simple’ again.

I especially cringe when someone says, ‘cooking a hamburger is easy with these simple food safety steps.’

Ho Phang and Christine Bruhn report in the current Journal of Food Protection that in video observation of 199 California consumers making hamburgers and salad in their own kitchens, handwashing was poor, only 4% used a thermometer to check if the burger was safely cooked, and there were an average of 43 cross-contamination events per household.

There’s some good data in the paper about what consumers do in their own kitchens, and the results are an additional nail in the self-reported-food-safety-survey coffin: people know what they are supposed to do but don’t do it.

But what the paper doesn’t address is how to influence food safety behaviors. Instead, the University of California at Davis authors fall back on the people-need-to-be-educated model, without out providing data on how that education – I prefer compelling information – should be provided.

The authors state:

• educational materials need to emphasize the important role of the consumer in
preventing foodborne illness and that foodborne illnesses can result from foods prepared in the home.;

• the gap between the awareness of the importance of hand washing and the actual practice of adequate hand washing should be addressed by food safety educators.

• food safety educators should address the lack of reliability of visual cues during cooking (stick it in — dp);

• food safety educators should emphasize faucet cleaning with soap and water as a way of preventing cross-contamination; and,

• ignorance about food irradiation point to a further need for education.

The authors do correctly note that program to promote the use of thermometers when cooking burgers, initiated by the introduction of Thermy in 2000, has not been successful. So why do more education?

And the E. coli O157:H7 outbreak in Jack-in-the-Box hamburgers happened in Jan. 1993, not 1994 as stated in the paper; someone should have caught that.

Abstract:
Ground beef has been linked to outbreaks of pathogenic bacteria like Escherichia coli O157:H7 and Salmonella. Consumers may be exposed to foodborne illness through unsafe preparation of ground beef. Video footage of 199 volunteers in Northern California preparing hamburgers and salad was analyzed for compliance with U.S. Department of Agriculture recommendations and for violations of the U.S. Food and Drug Administration’s Food Code 2009. A questionnaire about consumer attitudes and knowledge about food safety was administered after each filming session. The majority of volunteers, 78%, cooked their ground beef patties to the Food Code 2009 recommended internal temperature of 155°F (ca. 68°C) or above, and 70% cooked to the U.S. Department of Agriculture consumer end-point guideline of 160°F (ca. 71°C), with 22% declaring the burger done when the temperature was below 155°F. Volunteers checked burger doneness with a meat thermometer in 4% of households. Only 13% knew the recommended internal temperature for ground beef. The average hand washing time observed was 8 s; only 7% of the hand washing events met the recommended guideline of 20 s. Potential cross-contamination was common, with an average of 43 events noted per household. Hands were the most commonly observed vehicle of potential cross-contamination. Analysis of food handling behaviors indicates that consumers with and without food safety training exposed themselves to potential foodborne illness even while under video observation. Behaviors that should be targeted by food safety educators are identified.
 

No confusion here: cook ground beef to 160F

 As a Canadian citizen with permanent U.S. residency living in Australia, I get confused.

Even with a language professor by my side, I can barely understand a damn word anyone says – especially the Canadians.

Fellow Queenslander Pat Dignam also appears confused when he writes in the Irish Times that food irradiation “is routine in some countries, including the U.S., so eating rare hamburgers there is safe.”

No. A small fraction of American ground beef is irradiated, and almost none of that is available at retail or food service.

Mr. Dignam is correct when he says, “During the butchering process, the surface of cuts of meat may become contaminated with bacteria, notably E. coli, from the intestines of the animal (regardless of the standards applied by the farmer and butcher). Cooking an intact piece of meat on the surface is sufficient to kill any such bacteria. However, when a piece of meat is minced, contamination on the surface can be spread to any part of the product. … Irish mince is not irradiated, so the process of cooking through is crucial. E. coli infection can be fatal, so anyone who wishes to eat rare or raw minced beef in Ireland should take note of these facts.”

Well said, except for the U.S. bit. And things get confusing when intact cuts like steaks are needle-tenderized.

The facts are ground beef in the U.S. needs to be cooked to 160F (71C) as verified by a tip-sensitive digital thermometer.

Stick it in.

Cooking is not enough; Auchan recall frozen cheeseburgers because of E. coli O157:H7 ignores cross-contamination risk

French retailer Auchan is recalling frozen cheeseburgers because of E. coli O157:H7 contamination but said that if cooked properly, to 65 C, the consequences of such contamination were prevented.

This ignores the risk of spreading even minute amounts of E. coli O157:H7 around household kitchens and food service operations.

AFP reported the manufacturer of the burgers, Cerf, said that the product recall was made "on behalf of the precautionary principle."

??They are sold without a brand name but in a plastic bag which is drawn on an American flag, it was learned from the company. ??"A review has highlighted, in the raw materials used in these products before cooking, the presence of Escherichia coli O157:H7.”
 

Digestion disaster warning as barbecue season begins – in Germany

Foodborne illness also happens in Germany.

The number of campylobacter cases registered with the Robert Koch Institute has risen by nearly 50 per cent over the last 10 years, to reach around 65,700 last year. Of these, around 45 percent occurred between May and August.

“Care should be taken particularly with barbecuing and preparation of poultry.

“As the warm weather tempts people to dust off their barbecues and head for the parks for the Easter break, medics are warning that half-cooked hamburgers and barely-warmed-through bratwursts can cause digestion disaster.”

The Germans are as good as most other public health agencies in making consumers the critical control point and providing lousy advice.

Handle all food like toxic waste; use a thermometer.
 

Canadians encouraged to use digital food thermometers when cooking

It’s like me and Health Canada doing a two-step at a Good Brothers concert in Peter Clark Hall at the University of Guelph.

Or not quite.

But Health Canada did issue a statement today saying that Canadians should make sure their meat, poultry and seafood dishes reach safe internal cooking temperatures before serving, and that the only reliable way to ensure that your food has reached a safe internal cooking temperature is by using a digital food thermometer.

Despite many different types of food thermometers currently available on the Canadian market, digital food thermometers are considered the most accurate because they provide instant and exact temperature readings.

While we often look for other signs that our food is cooked properly (for example, the colour of the meat and its juices), these methods can’t accurately confirm that harmful bacteria have been eliminated from our foods. Bacteria, such as Salmonella, E. coli and Listeria, which can cause foodborne illness can’t survive at certain high temperatures.

I don’t know who the we are Health Canada is referring too. And a tip-sensitive thermometer will help bunches.

Faith-based food safety not enough, Dublin restaurant told to cook burgers

A Dublin restaurant has been told by the Health Service Executive (HSE) to stop serving burgers cooked rare and medium-rare or face legal action.

The Rathmines restaurant Jo’burger has been warned by the Environmental Health Officer with the HSE to serve only well-done burgers or prove that undercooked meat can be served without the risk of E. coli bacteria and other contamination.

Jo’burger received a written warning this month that continuing to serve burgers cooked rare or medium rare could represent a “risk to public health.”

Restaurant owner Joe Macken said he had first been warned about the issue of undercooked burgers when the restaurant opened over three years ago. He responded by putting a disclaimer at the bottom of the menu, telling customers: “We will serve your burger as you request it, rare to well-done. Rare and medium-rare burgers are undercooked. Note eating of undercooked or raw meat may lead to food borne illness.”

He said the rare and medium-rare burger was a popular choice among his customers.

Asked how he could be sure his customers would not get sick, he said he was not sure. “But we have a belief in our product,” he said, and in the abattoir that produces the mince and sends it to them vacuum-packed. “The last thing they want is an E.coli outbreak.”
