Pork

    Those supermarket loyalty cards helped pin down an outbreak of salmonella in sausage in France last year.

    Researchers reported in Eurosurveillance last week that an outbreak of the monophasic variant of Salmonella enterica serotype 4,[5],12:i:- occurred in November and December 2011 in France. Epidemiological investigation and food investigation with the help of supermarket loyalty cards suggested dried pork sausage from one producer as the most likely source of the outbreak. Despite the absence of positive food samples, control measures including withdrawal and recall were implemented.

    Between 31 October and 18 December (week 44 to week 50), a total of 337 cases of Salmonella enterica serotype 4,[5],12:i:- were identified. The median age was 10 years (range: 0–90 years) with about 30% of children under five. A majority of women were affected (female to male sex ratio: 1.22). Cases were reported throughout France.

    An epidemic of Salmonella enterica 4,[5],12:i:- was already observed about three months prior to this outbreak. Between 1 August and 9 October, 682 cases were reported (Figure 1), of whom 100 cases were interviewed at the time but no common vehicle of infection could be identified. In comparison, 212 cases with this serotype had been isolated during the same period in 2010.

    Epidemiological investigations pointed to a dried pork sausage purchased principally at supermarket chain A and consumed after week 44, 2011. Therefore purchases of pork delicatessen at supermarkets A and B up to four weeks prior to symptom onset were investigated by the DGAL using data recorded through supermarket loyalty cards.

    The use of the loyalty card from supermarket chain A was important to identify the vehicle of infection and the local producer involved in this outbreak. These cards are used more and more and prove helpful in the investigation of food-related outbreaks. Nevertheless we should keep in mind that they do not necessarily reflect the consumption of cases perfectly. For instance, the card may not be used systematically, the household can purchase foods in additional shops and markets for which they have no loyalty cards, many food products are consumed outside the household and not recorded on the card, and the central database of the supermarket does not always contain data on all foods sold such as foods directly purchased by the retailers. For these reasons the data have to be interpreted together with the results from epidemiological and microbiological investigations.

    That the producer and microbiological analysis did not find Salmonella does not exclude contamination. The limited number of samples and the processing of the food (especially salting and drying) reduce the likelihood of isolating the bacteria. Implementing checks earlier in the process (before salting and drying) and using additional methods of testing such as polymerase chain reaction (PCR) should be considered.

    This is the second described outbreak in France involving dried pork sausage, and indicates that this food item might be a likely vehicle of infection and further outbreaks in humans may be expected.

    Given the limitations to detect Salmonella in dried sausages, the ability of the standard reference method to detect of monophasic variant strains in dried sausages is questionable. Additional methods should be explored in order to improve monitoring protocols.

    When toxoplasma in pork ranked second in last year’s top 10 riskiest combinations of foods and disease-causing microorganisms at $1.2 billion a year, some wondered, what?

    Now the Brits have chirped in, saying much more needs to be known about Toxoplasma gondii in the country’s food and especially the impact on pregnant women.

    The UK Food Standards Agency’s (FSA) Advisory Committee of the Microbiological Safety of Food (ACMSF) is seeking stakeholder views on its draft report relating to toxoplasma in the food chain (available at http://www.food.gov.uk/multimedia/pdfs/consultation/criskprotoxoplasmafoodchain.pdf).

    According to the UK National Health Service (NHS), food sources include undercooked or raw meat, raw cured meat (including Parma ham, salami) and unpasteurised goat’s milk, and the infection can pass between humans from a pregnant woman to an unborn baby.

    Although toxoplasmosis usually only causes mild flu-like symptoms in adults, the ACMSF said it can be fatal to babies, and has been linked with associated jaundice, eye infections and seizures.

    The FSA’s scientific advisory committee was asked to consider whether current evidence indicates a food safety issue that needs to be addressed, what food sources could present a significant risk and identify further work needed on UK prevalence and foodborne sources of toxoplasmosis.

     Pork barbecue with vinegar and pepper-based sauce is the source of 23 per cent of salmonella-positive samples the U.S. Department of Agriculture reviewed from 2005 to 2010. The contamination has not caused any known illnesses.

    Exactly what part of the dish is contaminating it with salmonella isn’t clear. FSIS notes that it “may have come from the addition of contaminated ingredients (such as the pepper) to the sauce, or from cross-contamination of the product or sauce in the post lethality processing environment.”

    During processing of these products, the pork was cooked first, and the barbecue sauce was added after the cooking step. The lack of a lethality treatment for the sauce or its ingredients could result in contamination of the final product.

    Meatingplace.com reports inspectors were told to plan an awareness meeting on the subject, and to ensure that the plants they inspect have a HACCP plan that enables them to determine whether the establishment had a way of evaluating the safety of the ingredients added after the lethality step.

    Despite efforts to create a modern food-safety regimen in China, oversight remains utterly haphazard, in the hands of ill-trained, ill-equipped and outnumbered enforcers whose quick fixes are even more quickly undone.

    So says the New York Times in Sunday’s edition.

    Dr. Peter Ben Embarek, a food safety expert with the World Health Organization’s Beijing office, who’s usually blunt, said, “Most of them are working like headless chickens, having no clue what are the major food-borne diseases that need to be addressed or what are the major contaminants in the food process.”

    In recent weeks, China’s news media have reported sales of pork adulterated with the drug clenbuterol, which can cause heart palpitations; pork sold as beef after it was soaked in borax, a detergent additive; rice contaminated with cadmium, a heavy metal discharged by smelters; arsenic-laced soy sauce; popcorn and mushrooms treated with fluorescent bleach; bean sprouts tainted with an animal antibiotic; and wine diluted with sugared water and chemicals.

    Even eggs, seemingly sacrosanct in their shells, have turned out not to be eggs at all but man-made concoctions of chemicals, gelatin and paraffin. Instructions can be purchased online, the Chinese media reported.

    Scandals are proliferating, in part, because producers operate in a cutthroat environment in which illegal additives are everywhere and cost-effective.

    Manufacturers calculate correctly that the odds of profiting from unsafe practices far exceed the odds of getting caught, experts say. China’s explosive growth has spawned nearly half a million food producers, the authorities say, and four-fifths of them employ 10 or fewer workers, making oversight difficult.

    Since February, the Reference Laboratory at the Norwegian Institute of Public Health has identified identical strains of Yersinia enterocolitica O:9 in 20 patients living in Norway.

    Interviews with the patients with yersiniosis led to suspicion of a particular pre-packaged lettuce mix that was withdrawn from the market.

    Further investigation led to suspicion of several pre-packaged lettuce mixes purchased in grocery stores. Preliminary investigations conducted at the Norwegian Veterinary Institute strengthened this suspicion. The manufacturer has therefore withdrawn a further nine lettuce mixes from the market. The Norwegian Food Safety Authority recommends that consumers should not eat these lettuce mixes. The Norwegian Institute of Public Health is continuing the investigation in co-operation with the Food Safety Authority and Veterinary Institute.

    The producers of Bravo's Top Chef have me pegged as their target audience. Tonight's episode featured the Sesame Street characters Telly, Cookie Monster, and Elmo (who were hilarious judges), and new ads for Target featuring former Top Chef cheftestants and Padma. It's an entertaining episode that left me with a bad taste in my mouth.

    Tonight's challenge was to cook a meal for 100 employees in a closed Target super store in the middle of the night. Because of the improvised cooking setting, the chefs were forced to set up their kitchens, find their ingredients, and prepare to serve the employees and judges within a 3 hour time limit. Some concentrated on table linens, some on flavors, but there was a frightening absence of handwashing. Granted, many of the chefs opted to make soup, which in theory should allow for thorough cooking of all ingredients. But what about any fancy garnish and fresh salad that ends up on the plate?

    My favorite of the season, Richard Blais, made a pork tenderloin (pictured right exactly as shown). He then topped his finished pork with some freshly sliced apple and green chili slaw before serving. His concern? "It's not the prettiest dish in the world. I know that. But I'm ready to defend my dish if I have to. I think it's tasty."

    Anthony Bourdain confirmed, "Frankly, I think Richard's disk was butt ugly, but it was delicious."

    One day I hope a chef will stand up and protest the cooking conditions or demand a meat thermometer. I will leave the food safety assessment to the experts, but I spotted a few potential concerns:

    - using all cooking utensils and dishes straight from boxes with no chance to sanitize them

    - improvised utensils, linens, garbage cans, etc.

    - no handwashing stations, sanitizing solutions or rags to clean work surfaces or dishes.

    I have hit pause on the DVR so many times that I'm not even done watching this episode yet, but I hope it does not end with a foodborne outbreak.

    In a move to apparently counteract the negative associations with swine flu, Argentine President Cristina Kirchner told a gathering of business people at a meeting at the presidential palace that eating pork is at least as effective as popping a Viagra pill to spice up your sex life, stating,

    "Pork consumption improves sexual activity. This is not a small detail. Besides, some nicely grilled pork is much more gratifying than taking Viagra."

    Kirchner said she ate some roasted pork over the weekend with her husband, former president Nestor Kirchner, at the couple's retreat in Argentina's bucolic southern Patagonia region, with "impressive" results.
    "We were in high spirits the whole weekend," she said, smiling.

    The head of the association of pork producers, Juan Uccelli, on Thursday said people in Denmark and Japan, where pork consumption is high, "have much more harmonious sexual lives than us Argentines have."

    Reuters reported yesterday that new information from the World Health Organization suggested pigs sickened with H1N1 swine flu should not be consumed, despite earlier insistence that fully cooked pork is perfectly safe.

    The story states,

    "The WHO comments appear more cautious than those from the Food and Agriculture Organisation (FAO) and World Organisation for Animal Health (OIE), which said import bans are not required to safeguard public health because the disease is not food-borne and has not been identified in dead animal tissue.

    The WHO however said it was possible for flu viruses to survive the freezing process and be present in thawed meat, as well as in blood."

    Well, who in their right mind drinks raw pig blood thinking it won't possibly make them sick?

    I didn't find any statements on the WHO website that mentioned the ability of viruses to survive freezing--or its pertinence to the consumption of fully cooked pork--but I discovered that the WHO, FAO, and OIE have reissued their joint statement from April 30 today to address misunderstanding of the consumption of meat from H1N1 infected pigs. The statement reads, in part,

    "Authorities and consumers should ensure that meat from sick pigs or pigs found dead are not processed or used for human consumption under any circumstances."

    Sick or dead animals should never be slaughtered, regardless of the cause of illness or death. This  reduces the risk for cross-contamination. The statement reassures,

    "Heat treatments commonly used in cooking meat (e.g. 70°C/160°F core temperature) will readily inactivate any viruses potentially present in raw meat products.

    Pork and pork products, handled in accordance with good hygienic practices recommended by the WHO, Codex Alimentarius Commission and the OIE, will not be a source of infection."

    But I shouldn't be spelling this stuff out--the WHO should. And they should address the bit about viruses surviving freezing and how that impacts food handlers.

    Authorities should communicate the risks and how they're being managed (or can be managed) in a way the public can understand and the media can't mess up. It's their responsibility to a concerned public.

    Maybe it was the swine flu, maybe it was the bad Flashdance welder-by-day-peeler-by-night references, maybe it was the BBQ sauce, but an advertisement for White Castle’s new pulled pork sliders has disappeared, only to reappear through the magic of YouTube.

    Someone finally found the H1N1 swine flu in pigs.

    After I bashed them for allotting resources for hog surveillance when little evidence for such a need existed, the United Nation’s Food and Agriculture Organization is now applauding Canada for spotting the flu in a herd of Alberta swine.

    However, a person—not other swine—sickened the pigs.

    healthzone.ca reports that a carpenter at an Alberta hog farm went to work on April 14 after a visit to Mexico and may have brought the H1N1 flu with him. Within a couple weeks, about a tenth of the 2,200-hog operation showed signs of the flu.

    The affected hogs were quarantined and all are recovering or have already recovered. Only one other person who has had contact with the pigs shares signs of illness.

    Across Canada, however, canada.com reports that another 15 cases of H1N1 flu were confirmed last week, bringing the country’s total to 34. One case was a student at Beairsto Elementary School, which responded by closing for a week.

    Additionally, the story reports,

    “The federal government will launch a public awareness campaign Friday to inform Canadians about the swine flu as the number of cases in Canada climbed to 34 and the number of worldwide cases surpassed 270.”


    I hope these messages for the public contain more information than “you can’t get the flu from food,” which is about all I’ve heard so far.

    In a press release in the US, the director of science and technology for the National Pork Producers Council, Dr. Jennifer Greiner, was quoted as saying,

    "People cannot get the flu from eating or handling pork. The flu is a respiratory illness, it's not a food-borne illness."


    Then can someone please explain to their country how to manage these respiratory risks?

    Let’s talk more about what the risks are than what they aren’t.
