    Hockey goon and budding academic Kevin Allen of the University of British Columbia says there’s lots of listeria in ready-to-eat seafood in British Columbia (that’s in Canada).

    According to a new paper in Food Microbiology, Allen along with Lili Mesak and Javana Kovačevic found lots of anti-microbial resistant Listeria monocytogenes in ready-to-eat salmon, but none in RTE deli meats. The paper offers a thorough microbiologial and genomic description of the listeria strains isolated but what this means for consumers is less clear.

    But Kevin, describing listeria-vulnerable populations as “the really young and the elderly?” What about the really, really young? Or the super-young. The uber-young?

    Abstract below.

    Occurrence and characterization of Listeria spp. in ready-to-eat retail foods from Vancouver, British Columbia

    Abstract
    The occurrence of Listeria spp. and L. monocytogenes in retail RTE meat and fish products in Vancouver, British Columbia (B.C.) was investigated. To assess potential consumer health risk, recovered L. monocytogenes isolates were subjected to genotypic and phenotypic characterization. Conventional methods were used to recover Listeria spp. from deli meat (n=40) and fish (n=40) samples collected from 17 stores. Listeria spp. were recovered only from fish samples (20 %); 5 % harboured L. innocua, 5 % had L. monocytogenes and 10 % contained L. welshimeri. Listeria monocytogenes isolates serotyped as 1/2a and 1/2b, possessed dissimilar PFGE patterns, and had full-length InlA. Three 1/2a clonal isolates encoded the 50 kb genomic island, LGI1. Antimicrobial resistance (AMR) profiling showed all Listeria spp. possessed resistance to cefoxitin and nalidixic acid. Listeria monocytogenes were resistant to clindamycin, two were resistant to streptomycin, and one to amikacin. Reduced susceptibility to ciprofloxacin was seen in all L. monocytogenes, L. innocua and three L. welshimeri isolates. Reduced susceptibility to amikacin and chloramphenicol was also observed in one L. monocytogenes and three L. welshimeri isolates, respectively. Recovery of L. monocytogenes in fish samples possessing AMR, full-length InlA, LGI1, and serotypes frequently associated with listeriosis suggest B.C. consumers are exposed to high-risk strains.
    Highlights
    ► Listeria spp. were frequently recovered from RTE salmon samples, but not deli meat. ► High risk strains of L. monocytogenes were present in BC retail RTE seafood. ► This is the first report of the LGI1 genomic island from retail RTE seafood. ► AMR was observed in all Listeria, and included clinically relevant antimicrobials

    I’m still waiting for some brave food producer to start marketing food safety at retail because I don’t care if lettuce and spinach are local, natural, sustainable, and was produced without harming any animals: I do care if it has E. coli and I want to know what a brand is doing about it. At the grocery store. Where I decide what brand to buy.

    A group of Mexican produce producers is, according to The Packer, planning to invest in the issue with the Eleven Rivers Growers food safety and quality assurance label.

    And while starting with the supply chain, the group wants the labels at retail by 2013.

    “We believe that we will have 22 or 23 producers (under the label),” said Fernando Mariscal, cooperative representative. “Most important, we are expecting to have production around 40 million 25-pound boxes for this winter season.

    "We’ll start the process with weekly inspections that are not going to be announced,” Mariscal said.

    The unannounced part is good, but Eleven Rivers is going to rely on third-party auditors like Primus Labs or Scientific Certification Systems, or anyone who can meet the standards, which could be bad. Better to have some in-house expertise to make use of the audits are really create a strong food safety culture, one strong enough and backed up with date to support safety claims at retail.

    Grower-shippers pay about five cents a box for the labels. Those who pass the inspections will add Eleven Rivers Growers to their existing labels. Any who fail lose the label until the causes are addressed.

    For now, the label will only go as far as the pallet level — basically, a 4-inch tape around pallets.

    “It’s our aim to reach the supply chain this year,” Mariscal said.

    “Next year we hope to reach the final consumer, label each box and be present at the supermarkets.”

    Because of that limit, the cooperative will push to keep pallet quantities together.

    “We’re trying to show that pallet has been carefully monitored from crop to distribution, that it’s been well-handled all the way. Because some of the shipments will go to other suppliers, like terminal markets or brokers, we have to be sure it remains within its quality conditions.”

    Commodities include a mix of tomatoes, bell peppers, chilies, cucumbers, eggplant, green beans and squash. Plans call for adding more crops over time.

    Among the participating members in the nonprofit cooperative are Del Campo y Asociados; Tricar Sales; Triple H; Grupo GR; De La Costa; CAADES Sinaloa; Agroindustrias Tombell; Agricola de Gala; Agricola EPSA; and Agroexportadora del Noreste.

    Elizabeth Weise in USA Today doesn’t really answer the who-should-pay question, but does ask, what if it were possible to almost entirely do away with E. coli in ground beef and it would cost only about a penny a burger?

    Food-safety experts say it's entirely feasible with new technologies that have become available. One is a vaccine, the other a feed additive, which, given early enough, could bring down potential E. coli contamination to negligible levels.

    The problem, experts in beef safety say, is that the economics are backward. The new interventions have to be administered long before the cattle are slaughtered, when the calves are young or in feedlots where they're growing.

    It's hard to figure out who should pay for steps that would take place months and possibly years before the grill starts sizzling. The people who'd have to pay for them aren't the ones who would reap the direct benefits.’’’

    These interventions aren't perfect, but they're very good, says Guy Loneragan, a professor of food safety at Texas Tech University in Lubbock. "The question is no longer, 'Can we get the technologies?' We've got them, or they're soon to arrive. The question is 'How do we implement?' "

    So far only two small companies appear to be embracing them. One is a tiny feed lot cooperative in Kansas that's looking to vaccinate all its cattle "soon." The other is a Meade, Kan., cooperative that's staking its economic life on calling for retailers nationally to demand these interventions from the packers that supply their meat.

    The regulatory landscape "is confusing," says Elisabeth Hagen, USDA's undersecretary for food safety. "But we're realizing that there's an issue here and somehow we have to bring everybody together and focus on the end product, the result of which is the safety of the food that goes to the American consumer."

    Loneragan says they've gone as far as they can after the animal is slaughtered. Now the focus needs to be on ridding the animals of E. coli O157:H7 before they get to the slaughterhouse. The new methods to do that involve:

    •A vaccine. The biggest and potentially most game-changing treatment is a vaccine introduced by Pfizer Animal Health in 2010 and given in a three-shot series starting when the calf is just 6 months old. This gets rid of the E. coli O157:H7 bacteria in 85% of the cattle, says Brad Morgan, a senior food-safety specialist at Pfizer Animal Health in Stillwater, Okla. Not only that, but even among the ones that still have the bacteria in the gut, the injections reduce the amount the animals shed in their manure by 98%, he says.

    It's not all or nothing. Pfizer has done studies showing that if only 50% or even 25% of cattle are vaccinated, rates of E. coli are strongly reduced in the feed yard, and therefore in the packing plant. And Harvard's Hammitt says his research shows that Americans understand that food can't be "perfectly safe," but they want safer.

    The vaccine costs $4 to $6 per animal for the full series, says Loneragan. There are several other vaccines in the regulatory pipeline here and overseas.

    •The probiotic. The other intervention is a probiotic added to feed. These are beneficial bacteria cultures that out-compete the more dangerous forms of E. coli in the cattles' guts, much as yogurt is said to seed the gut with good bacteria to keep out the bad. Many studies have found that using "the right strain at the right dose you can get a fairly predictable 40% to 50% reduction in E. coli O157:H7," says Loneragan.

    The American Meat Institute Foundation, the research arm of the meat industry trade group, says there just isn't enough data yet to know if these treatments work. While there's been a tremendous amount of research and it looks promising, "We're right at the cusp of understanding the technology," says Betsy Booren, the institute's director of scientific affairs.

    Last year Cargill, one of the nation's largest beef producers, conducted a trial of the E. coli vaccine on 85,000 head of cattle at its Fort Morgan, Colo., beef-processing facility, says spokesman Mike Martin at Cargill's Wichita headquarters.

    The trial's results were "inconclusive," Martin says, in part because the levels of O157:H7 they found on the cattle in general "were the lowest in years . …" There was "very little difference" in rates between the vaccinated and the unvaccinated cattle, he says.

    Loneragan says in the studies he's done, E. coli O157:H7 levels were indeed low but dropped lower in meat from vaccinated cattle.

    In the end, it's going to take movement by the biggest companies to move the industry. There are two that could make this happen in a second, McDonald's and Wal-Mart, says Chuck Jolley, a meat industry marketing company executive.

    "If either decides to require it, the industry will turn around on a dime," he says.

    TV celebrity Dr. OZ says, ‘We have a right to know if our food has been genetically modified.’

    I’ve been saying the same thing for 20 years – just put some boundaries on what is genetic modification, because all food is genetically modified, and figure out the best way to provide that information without imposing on others who don’t care about such lifestyle choices.

    As a physician though, why isn’t Ozzie outraged about all the millions of people who get sick from the food and water they consume each year? 23 dead and 116 sick from cantaloupe is perhaps too graphic when compared to the histrionics that can be generated by hypothetical risks.

    Similarly, Justin Gillis writing in the New York Times reports about self-proclaimed deep thinking going on in the food sustainability camp – which is as vague as the no-GMO camp – and that an intriguing idea is a new certification system for sustainably produced food.

    “Instead of catering to a single ideological predilection, the way the organic label does now, the new label would be based on a system that awards points for public benefits and subtracts them for environmental harm. Foods produced according to the best practices would get the highest scores, or possibly the highest letter grades. If consumers adopted it, such a certification would put pressure on companies and farmers to clean up their practices.”

    Consumers have the power. Oz Man, take up the cause of microbiologically safe food: we have a right to know if food will make us barf.

    A colleague sent me these pictures of fish seasoning purchased in a San Francisco Asian supermarket. The back mentions both HACCP (Hazard Analysis Critical Control Points) and ISO 9001, but doesn’t say what either mean.

     

     

     

     

     

     

     

     

     

    In Brisbane, we bought a pint of fresh strawberries from Gowinta Farms, which bills itself as the largest strawberry farm on the sunshine coast, featuring a café, fruit shop, packhouse, transportation and a workshop.

    And you can see from the plastic container, it’s all HACCP-certified.

    I’m not sure what that means, or if consumers know what it means, but these are further indications of baby-steps to start promoting microbial food safety directly to consumers.

    Eater reports that 60-year-old East Austin barbecue legend Sam's BBQ, Willie's Bar-B-Que and La Morenita all had their business licenses revoked as a result of Operation Meat Locker. Austin police had been working with HEB for the past three months to bust meat thieves — it's a "growing crime" in Central Texas.

    Apparently thieves shove meat down their pants to sneak it out of grocery stores and "walk long distances or ride the bus" in order to sell it to restaurants.

    Shockingly, investigators discovered "food safety was not a priority."

    Officers posing as meat thieves approached 25 restaurants with the stolen meat, and only the three listed above went for it. Five arrests have been made. The restaurants can apply to have their permits reinstated but must remain closed until that happens.

    Willingness-to-pay studies are excellent indicators of what people think they will do in imaginary situations.

    Willingness-to-pay studies are terrible indicators of what people will actually do at the grocery store.

    Brian Roe, professor of agricultural, environmental and development economics at Ohio State University (isn’t that The OSU?) and Mario Teisl of the University of Maine report in the journal Food Policy, that based on surveys from 3,511 individuals, Americans would be willing to pay about a dollar per person each year, or an estimated $305 million in the aggregate, for a 10 percent reduction in the likelihood that hamburger they buy in the supermarket is contaminated by E. coli.

    A monkey just flew out of Wayne Campbell’s butt (see video below from last week’s Saturday Night Live).

    By comparison, a 2008 U.S. Department of Agriculture analysis estimated the value of eradicating a specific type of E. coli contamination from all food sources would result in a benefit valued at $446 million.

    In the questionnaire, they set up six hypothetical scenarios around the purchase of either a package of hotdogs or a pound of hamburger. They set prices for the packages – both "status quo" foods and those treated with either ethylene gas processing or electron beam irradiation to reduce contaminants – and then laid out a variety of probabilities that the treated or untreated food packages contained contamination with either E. coli or listeria, another pathogen that can cause food-borne (sic) illness.

    They followed by asking respondents to choose one of three actions: buy the food treated with the pathogen-reducing technology, buy their usual brand, or stop buying this product altogether.

    The results showed that consumers will reach a limit to how much they want to pay to reduce their chances of getting sick. If the treated product cost only 10 cents more than an untreated package, about 60 percent of respondents said they'd buy the improved product. But when that higher price reached $1.60 more per package, less than a third would opt for the treated product.

    The structure of the survey also allowed researchers to see the influence of human behavior and opinions on likely illness outcomes.

    "If the food industry were forced to put technology in place that lowered the presence of E. coli and that ramped up prices to the extent where everybody had to pay about a dollar more out of pocket each year for hamburger, we're saying that, according to this model, that would be about an equal tradeoff for the U.S. population. And if the technology costs only about 10 cents per person instead, that would seem like a good deal to most people," he said.

    "If regulators could become more comfortable with this measurement process, agencies might change the way they conduct their cost-benefit analysis. And that would be an interest of ours, to see if our work and others' work in this area will eventually change the way people attack these questions."

    So it’s more about changing the way estimates are done. Estimates are lousy surrogates. I’m all for marketing food safety – at retail, food service, markets, everywhere. Brag about test results, use big signs, smart phone readers, just be able to back it up.

    Food safety types in Birmingham, U.K. have found that 40 per cent of all plastic packaging containing chicken in Birmingham contained food poisoning bacteria.

    In a survey of 20 supermarkets, convenience stores and butcher’s shops throughout the city, food safety officials found that eight were contaminated on the outside of the packet.

    They also found seven chickens were contaminated inside the wrapping, while one tested positive for salmonella. There was no link between those infected inside and outside the packaging.

    Team manager Nick Lowe said, “Our message to consumers is that handling the packaging should be regarded as just as likely to cause food poisoning and touching the raw meat.”

    Once handled in a supermarket the bacteria can be passed on through trolley handles, shopping bags and transferred to other foods. In one supermarket a pool of juice collected on the chiller shelf was also contaminated.

    Memories can be short when it comes to food recalls.

    Amy Schoenfeld writes in Sunday’s New York Times that while Americans are concerned about food contamination, experts say that recalls have only a short-term effect on consumers.

    When spinach was recalled in 2006, consumers took over a year to return to previous spending patterns. But after recent recalls of peanut butter, beef and eggs, customers came back in a matter of weeks.

    One explanation for this is that eggs are a staple; nearly 9 in 10 Americans say they eat them. By contrast, only 5 in 10 Americans say they are spinach eaters. After the spinach recall, 10 percent of spinach eaters said they were unlikely to eat spinach again. In contrast, 3 percent of egg eaters said they would stop purchasing eggs.

    Rather than waiting to sue after sickness, consumers could use their buying power to demand microbiologically safer food, if someone would start marketing at retail.

    There’ll be the usual posturing, handwringing and contrition for the cameras at today’s Congressional hearing in Washington, D.C.

    Philip Brasher of the Des Moines Register reports this morning that Jack DeCoster and his son, Peter, will apologize at a House Energy and Commerce subcommittee meeting today to the 1,608 confirmed victims of a salmonella outbreak and pledge not to resume selling fresh eggs until their farms are free from disease.

    “While we always believed we were doing the right thing, it is now very clear that we must do more,” said Peter DeCoster, who is chief operating officer of the Wright County Egg operations, which his father owns.

    In a 10-page statement obtained by The Des Moines Register, the men point to a feed ingredient purchased from an outside supplier as the likely source of the salmonella contamination. Federal investigators have reported finding salmonella in several areas of the farms in addition to the feed mill.

    This is a terrible strategy. Blaming others and failing to outline what DeCoster and Son were actually doing in terms of testing and other steps to manage the risk of salmonella – before the outbreak -- will be a rhetorical playground for even the most addle-minded Congressional-types.

    It’ll be like angry parents scolding a teenager who says, sorry, I won’t do it again.

    The accused is sorry he got caught.

    Again.

    The N.Y. Times documented this morning the 1987 salmonella-in-eggs outbreak that killed nine and sickened 500, linked to farms owned by … Austin Jack DeCoster.

    Farms tied to Mr. DeCoster were a primary source of Salmonella enteritidis in the United States in the 1980s, when some of the first major outbreaks of human illness from the bacteria in eggs occurred, according to health officials and public records. At one point, New York and Maryland regulators believed DeCoster eggs were such a threat that they banned sales of the eggs in their states.

    How many others were sickened by DeCoster and Son eggs over the intervening 23 years, in the absence of an outbreak?

    Government’s hopeless.

    Market microbial food safety at retail so I, as a consumer, have a choice, so I can reward those egg producers who effectively manage salmonella – before there’s an outbreak.
