    “It’s just a shame that an activist with an agenda can really degrade the safety of our food supply.”

    That’s food safety guru David Theno, who is credited with turning the Jack in the Box burger chain into a model of food safety after an E. coli outbreak in 1993, commenting on the demise of pink slime, also known as ammonium hydroxide.

    McDonald’s and two other fast-food chains have stopped using an ammonia-treated burger ingredient that meat industry critics deride as “pink slime.”

    The product remains widely used as low-fat beef filling in burger meat, including in school meals. But some consumer advocates worry that attacks on the product by food activist Jamie Oliver and others will discourage food manufacturers from developing new methods of keeping deadly pathogens out of their products.

    The beef is processed by Beef Products Inc. of Dakota Dunes at plants at Waterloo, Iowa, and in three other states. One of the company’s chief innovations is to cleanse the beef of E. coli bacteria and other dangerous microbes by treating it with ammonium hydroxide, one of many chemicals used at various stages in the meat industry to kill pathogens.

    “Basically, we’re taking a product that would be sold at the cheapest form for dogs, and after this process we can give it to humans,” Oliver said in a segment of his ABC television show, Jamie Oliver’s Food Revolution, that aired last spring.

    BPI, which once boasted of having its product in 70 percent of the hamburger sold in the country, has lost 25 percent of its business. McDonald’s has been joined by Taco Bell and Burger King in discontinuing use of the product, and the company is worried other chains and retailers will follow them.

    Lean beef long has been added to fattier meat to produce the blends of hamburger meat that’s sold in supermarkets and restaurants. BPI’s innovation was to develop high-tech methods of removing bits of beef from fatty carcass trimmings that had previously been sold for pet food or animal feed and then treating the beef with ammonium hydroxide gas to kill bacteria. Ammonia is used extensively in the food industry and is found naturally in meat. The gas BPI uses contains a tiny fraction of the ammonia that’s used in household cleaner, according to the company.

    Theno, who has consulted for BPI, called the process “extraordinarily effective” in making beef safer.

    Two years ago, Beef Products Inc. took a fairly public hit when the N.Y. Times and several scientists questioned the efficacy of the company's use of ammonia as an antimicrobial treatment for ground beef.

    But in 2010, BPI founder and chairman Eldon Roth announced the company will post on its Web site 100 per cent of its results from the processor's testing for E. coli O157:H7 and salmonella.

    "We're going to be 100 percent transparent," Roth told Meatingplace in an interview following the announcement. … We're not promising to be perfect, but I will promise that we will be better.”

    In July, 2011, BPI won further praise for expanding its E. coli O157:H7 test-and-hold program in lean bean to six additional shiga-toxin producing strains of E. coli.

    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.

     In Oct. 2010, a massive outbreak of Salmonella enterica serotype 4, 5, 12: i- sickened about 600 students in schools in Poitiers, France. For that many students to get sick, there was a massive contamination, probably coupled with massive failures in storage and preparation. At the time, there was extensive criticism regarding the failure to communicate the severity of the outbreak (in a Cool hand Luke sorta way, see clip).

    These issues are not discussed in a new report by the Institut de Veille Sanitaire, but the epidemiological investigation is presented.

    In October 2010, a salmonella outbreak occurred in schools in Poitiers. Salmonella enterica serotype 4, 5, 12: i- was isolated from stool samples of the first cases. Environmental investigations identified frozen beef burger meat from a single brand served in schools as the cause of the outbreak and food trace-back investigation led to identification and recall of beef burger. We conducted an investigation to assess the extent of the outbreak in the schools of Poitiers.

    We conducted a retrospective cohort study. A self-administered questionnaire was filled by students and personnel attending the four exposed schools with cases. Clinical cases were defined as anyone reporting diarrheal or fever with at least one digestive sign within 5 days after school meal. We computed relative risks (RR) with their 95% confidence intervals (95%CI) and used the proportion test.

    We identified a total of 554 cases (544 adolescents and 10 adults) of the 1559 responders (response rate 86%) who ate at school on the day the burger meat was served. The overall attack rate was 36,5%. Attack rate was significantly lower for one school (17%, p <0,01) compared to the three others. Adolescents (<20 years) were at greater risk than adults to develop signs (RR= 2,3; 95%CI 1,3-4,2). A total of 286 cases (53%) sought medical care, of which 31(6%) were hospitalized >24 hours. Concentration of salmonella in burger meat varied between 270 and 18,000 CFU/g³.

    The serotype 4,5,12:I was associated with a severe outbreak, the largest salmonella food borne outbreak ever documented in a school setting in France. Quick identification and recall of incriminated batch is crucial to limit extension of outbreak.

    Thanks to Albert Amgar for passing along the report.

     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.

     A week after Washington State health types made Burger King Corp. aware of a problem with its burger cooking process, the company says that it's inspecting its systems on the West Coast to determine what changes need to be made.

    Most of the undercooking was due to problems with a flame broiler and employees failing to discard undercooked patties.

    Susan Shelton, environmental health specialist for the Benton Franklin Health District, said the problem in a nutshell was one of being unfamiliar with the new technology.

    "It wasn't cooking to temperature because there were a lot of controls. When we started working with them, it was resolved."

    The health district received no complaints about undercooked food or illnesses, and no lab samples were positive for bacteria or other illness-causing contaminants, she added.

    A human tooth was found in a burger made by Bigard in Quimperlé, sold by a supermarket in Angers, France.

    Nathalie Dayiot discovered the tooth crown was in a burger prepared by a friend at his home in Angers. He bought it in trays guaranteed "100% muscle" in the Grand Carrefour Maine Angers. "I felt something hard, says the young woman. I spit. It was a tooth on a pivot."

    Romuald Gross, who made the purchase, has every intention to complain to the Directorate General for Competition, Consumption and Fraud.

    The hamburgers were manufactured at Bigard in Quimperlé. The consumer advocate, Mr. Julien Roulleau, said two of the four who had attended the lunch were victims of food poisoning recorded this morning by their doctor, following the consumption of hamburgers. "The remaining burgers were seized by the DGCCRF. Beyond the problem of the tooth, it is important to know if the lot was consumed," said Me Roulleau.

    Carrefour's management promised an internal investigation and states that "the traceability of the product was traced back to the supplier concerned and to the manufacturing site."

    There is so much crap on the Internet.

    Ozersky.tv has some dude claiming to make the perfect burger; it’s a perfect example of microbial cross-contamination as he handles the meat and then everything else.

    Ozersky likes his burgers medium-rare and pink in the middle; crustry throughout, with no temperature verification and a side of dangerous microorganisms.

    He also uses slices of Velveeta because it melts at room temperature.

    There’s a lot of talk about hamburgers in the run-up to Father’s Day and most of it is crap.

    Literally.

    Someone in Japan made a hamburger out of human poop, the use-a-piece-of-metal-and-sear-your-tongue method of checking whether a burger is done is making the rounds, and someone else says 120F beef is safe.

    The poop burger is the safest choice.

    Because if you’re going to eat poop, at least cook it (and try not to cross-contaminate the kitchen).

    My Health News Daily reports today researchers in Japan have synthesized meat from proteins found in human waste.

    "In the food safety world we say, 'don't eat poop,'" said Douglas Powell, a professor of food safety at Kansas State University. "But if you're going to, make sure it's cooked."

    The Japanese researchers isolated proteins from bacteria in sewage. The poop-meat concoction is prepared by extracting the basic elements of food — protein, carbohydrates and fats — and recombining them.

    The meat is made from 63 percent proteins, 25 percent carbohydrates, 3 percent lipids and 9 percent minerals, according to Digital Trends. Soy protein is added to the mix to increase the flavor, and food coloring is used to make the product appear red.

    The researchers came up with the idea after Tokyo Sewage asked them to figure out a use for the abundance of sewage in mud, Digital Trends says.

    Powell is not familiar with the researchers' method, but said he guesses that they are first heat-treating the sewage before they reap its resources.

    "Theoretically, there's nothing wrong with this," Powell said. "It could be quite safe to eat, but I'm sure there's a yuck factor there," he said.

    However, Powell said there is the potential for cross contamination in the laboratory where the poop meat is made. That's why it's a good thing the meat will eventually be cooked.

    But what if the final product was not going to be cooked?

    "I wouldn’t touch it, " Powell said.

    Pass it on: Meat made from poop is safe, but you should cook it before you eat it.

    Eight children in Northern France have been admitted to hospital after eating beef burgers bought frozen from the German discount chain Lidl.

    "One of the children was put on dialysis overnight," Health Minister Xavier Bertrand said on Radio Classique. "His condition has worsened."

    The children, all aged between 20 months and 8 years, fell ill with symptoms such as bloody diarrhea. One was discharged from hospital on Wednesday.

    Health authorities have blamed the contagion on beef burgers sold frozen for distribution under the "Steaks Country" label.

    Privately-owned Lidl, which distributes burgers that are produced by French frozen-beef supplier SEB-CERF, has pulled all "Steaks Country" brand burgers from supermarket shelves.

    At least five children were hospitalized for food poisoning of a rare type of E. coli in France. At least 4 of them had eaten frozen hamburgers sold by Lidl stores.

    The serotype is not the same as in the German outbreak, according to authorities.

    The 5 children are aged from 20 months to 8 years and one of them was hospitalized this weekend in a pediatric unit. All five victims had serious bloody diarrhea and suffering from hemolytic uremic syndrome, explained Dr. Joëlle Perrin, medical advisor in the regional health agency.

    Health authorities have identified that four of the five children ate frozen beef burgers from the Steaks Country brand sold in Lidl stores.
