Food Safety Talk 41: Always Looking Out for Nuts

Added on by Ben Chapman.

Don shared that he’s been flogging the podcast mercilessly during his recent travels. The guys then launched straight into the Bug Trivia segment, highlighting Clostridium perfringens, which can be a big problem particularly for meat processors who need to cool large cuts of cooked meat quickly (to meet the FSIS performance standard). Carl Custer’s notes indicate that it was infamous for causing gas gangrene. During cooking of meat the spores germinate and these can grow incredibly fast if the rate of cooling is inadequate. Luckily it generally doesn’t cause death, but can cause a potentially fatal disease called pig-bel especially in countries where cooked meat is held at room temperature for long periods of time. Ben has developed some food safety infosheets for this organism, including this one detailing an outbreak linked to a school event.

The guys then turned their attention to baked goodies and that some things on the Internet are not true. Don referred to one of those typical urban legend emails warning people to discard their out-of-date pancake and cake mixes for risk of causing anaphylactic allergic reactions. Turns out that there is some truth to the matter as you can see from Snopes and this scientific article “An unusual case of anaphylaxis. Mold in pancake mix.” While there are some incorrect aspects to the story, Don would always advise people to not use food that has passed its best or sell by date because of the lower quality (the dates are there for a reason).

The conversation then turned to canning as Ben, the self-proclaimed Canning King of Wake County NC, recently received a question about canning mushrooms. While the email appeared to be about quality, Ben’s concern was Clostridium botulinum (see bug trivia in FST 39) and hence he elevated this email to an 11 on the 1 to 10 scale. So, Ben passed on information on canning mushrooms from the National Center for Home Food Preservation. Don was also dealing with canning questions and was worried about people fiddling with established jam recipes for fear of a repeat of what happened in Cowichan with watermelon jelly.

Ben then went on a Salmonella-fuelled hazelnut caper – he was grumpy about the lack of supplier information provided by the CFIA, although Lynne Terry from The Oregonian managed to find it out. Ben felt this information could be important to other distributers who would be able to make better decisions (provided they had the right food safety culture). Don noted that weenie public health folk, such as Dr. Eric Wilke, had Doug all fired up. Dr Wilke’s antics at the press conference turned serious foodborne illness outbreak into bizarre theater. Not cool, dude. The Salmonella outbreak from Fayetteville Hotelon the I-95 reminded Don of FST 11 and the guys discussed some of the ill-informed responses of public health officials after food borne illness outbreaks.

Don and Ben then turned their attention to needle tenderized beef, which was prompted by the MeatingPlace opinion about this Consumer Reports article. While James Marsden was against labeling of mechanically tenderized beef, Canada has already moved to such a labeling requirement, although Doug had some questions about it. Ben had managed to find some research on cooking inoculated and mechanically tenderized beef, although the debate about it is ongoing. Both Ben and Don would prefer to have this type of product clearly labeled, although their preference is for naturally tender and flavorsome beef cuts (such as MSA graded beef).

In the after dark the guys talked about Don’s upcoming trip to Brazil and Denmark, and Ben's trip to Nebraska.

The show started with Ben struggling to get the sound right. Then guys talked about writing proposals and how Ben’s bitten off more than he can chew.

Prompted by Amy Jane Gruber’s experiences with allergies on Salt & Fat, including her allergy to chicken proteins, the conversation turned to allergy awareness and where it fits with food safety. The guys shared their own experiences – Ben’s reactions to aspirin and Don’s sons allergies and intolerances to milk and lactose.  This prompted a broader discussion of allergies, controlling allergens and cross contamination. They discussed the similarities and differences compared to microbial cross contamination. Don noted the importance of tools such as GloGerm that can provide immediate feedback to people on how cross-contamination works.

The guys then talked about the Cleveland County (NC) fair E. coli outbreak in October, for which the final investigation report had been alluded to. The report apparently (although it isn't online) identifies a number of risk factors but no definitive source. The epidemiologists considered the possibility of insect vectors contributing to the outbreak, the potential for which has previously been identified. Don recalled a 1999 paper that reported experiments on the transmission of E. coli O157:H7 by fruit flies. While this work showed the possibility of such transmission, Don questioned whether there is any epidemiological evidence to show its importance.

Then the guys moved on to antibiotic resistance of Yersinia in US pork, which was prompted by this Consumer Reports article, which was followed by this Food Safety News article. Subsequently, Don was interviewed for Food Safety News where he questioned the public health significance of the findings, as Yersinia has previously been found in pigs, though there was some evidence associating Yersinia with pork chitterlings. Ben thought that while the industry has long been managing Yersinia, the Consumer Report article has ‘unearthed’ and publicized its presence in pork, even if it’s a none-issue. Ben felt that the most important part was for industry to communicating the risks, and controls, before someone else points out the risks, such as Beth Weise in this Thanksgiving article. While the guys agreed that “science by press release” wasn’t transparent and rigorous enough, Ben looked at the bright side, namely that the article has provided an opening to discuss food safety in a broader sense.

The guys then talked about a bunch of non food safety related stuff. Don then commended Ben on his appearance on the 5by5 show "The Frequency." Don was also excited about finding out about John Roderick’s TourFoodRules. Ben thought he wouldn’t eat at a place called “Crazy Fingers” (Rules 3 & 4 combined – and it actually exists) which reminded Don of a Grateful Dead song and Ben of Fubar.

In the After Dark, Ben expressed his frustration with not finding anything in iTunes 11 and that the guys can only see the US reviews of FoodSafetyTalk. Andreas confirms that only he has submitted a review in the Australian iTunes store. Don explained the extended family’s traditional Brooklyn Christmas Eve celebration and Ben also shared his Christmas plans.

Food Safety Talk 12: Dueling Experts

Added on by Don Schaffner.

Ben has McDonalds for lunch, which starts the guys talking about the golden arches, food safety and comfort foods, with brief digressions into banjo music, which is a Deliverance reference. Apparently they have rednecks in Canada too.

From there the guys talk about Don's Extension Stakeholder Review and the trials and tribulations of a life in academe. Food Safety Talk is not a productivity podcast, despite the fact that the guys talked about Getting Things Done by David Allen, and a survey on how people fall off the GTD wagon. Don also mentions The Checklist Manifesto by Atul Gawande that he is listening to as an Audible audiobook.

Ben brings the discussion back to food safety by talking about his food safety infosheets and building a Food safety culture as per Yiannis, Griffiths, Ben and Doug). Ben also brings up Malcolm Gladwell. Don holds his tongue and doesn't mention what others have said about Mr. Gladwell.

Don starts the food safety talk in earnest with a mention of the outbreak linked to Your Family Cow, with an aside to Abbott and Costello. Don also mentions his talk on sampling raw milk for pathogens and the early history of HACCP. This evolves into a discussion of sampling and the uncertainties of epidemiology, and the dangers of possibly getting it wrong.

Ben notes that he thinks that Edwin Shank from Your Family Cow guy, does get some aspects of his message correct, noting that Mr. Shank said:

... we are concerned. We do not take even a suspicion of food-borne illness lightly. We took action accordingly.

After a quick digression on Ben's microbe ornaments (not actual size), Ben moves the discussion to labeling, including meat and the USDA cook to a safe internal temperature label, unpasteurized juice labeling, Pillsbury's polite message, and more terse advice from Betty Crocker, regarding Bisquick. Don chimes in with concerns about the profusion of food allergy labels.

The guys get sidetracked into a discussion of dough and flour related food safety including the E. coli outbreak linked to refrigerated cookie dough, the Aunt Jemima Salmonella in flour mix recall, and the Listeria in Eggo frozen waffle recall.

Ben brings things back to consumers and labeling by mentioning research by Kansas State scientists on consumer preparation of frozen, uncooked, breaded chicken products. Not to be outdone, Don mentions research from his lab on the risk of salmonellosis associated with consumption of raw, frozen chicken products cooked in low-wattage microwave ovens.

Food labels seem to be getting longer and more complicated, but even with increased complexity, managing risks of things like hydrolyzed vegetable protein recall may be problematic give the different ways people eat Ramen Noodles, for example. Clearly the safety of microwaved foods is complicated, as microwaved containers also pose non-microbial risks, like tipping over and burning you.

Finally, no discussion of labeling snafu's would be complete without a mention of those kosher "broiled" chicken livers, which made a bunch or people sick, including one reported case in Minnesota. Why do more people seem to get in Minnesota? Here is a hint, it has a lot to do with the Minnesota's commitment to public health including efforts like Team Diarrhea.

Ben concludes by noting that he is a fan of Canadian Marshall McLuhan, even if he gets the quote wrong.

The guys wrap up with a discussion of ideas that they will put in the parking lot for future shows:
