This show opens with Ben talking about his experiences at a recent "invitation only" meeting with Sonny Perdue (and 100 of his closest friends) and how he (Ben) almost got arrested for doing research. Don counters with his appearance on the Do By Friday podcast to talk about Sous Vide-ing shoes and bras, and more. The guys respond to listener feedback on unclear coffee recall notices, and donating expired foods. The discussion turns to junk science, and puppy-borne disease before wrapping on naming beers and pubs by neural network.

Food Safety Talk 45: My chicken is dry

Added on by Ben Chapman.

Ben had difficulty talking while eating, which didn’t matter too much while the guys discussed the weather. A link from fan Erin (see also barfblog coverage), on the emerging food-safety-expose genre got Don and Ben warmed up for the show.

To follow up from FST 44, Ben’s H. pylori issues have been resolved, though one of his hockey friends had an interesting story involving yogurt. The guys then followed up on the mechanically tenderized beef discussion from FST 43 and FST 44, and a bit about Ben’s grad student’s research plan.

The guys then took a pop culture detour thanks to Ben worrying about peaking to early (research wise speaking), which remind Don of a Dan Bern’s Tiger Wood song. The discussion also covered Sound City, and some Australian pop-culture with Muriel's Wedding and The Castle.

In the bug trivia segment the guys focused on Vibrio parahaemolyticus, which is the other fast growing bacterium (c.f. FST 39) and can double every 7 minutes under optimal conditions. Don was familiar with this organism as he’s published about the effects of lime juice on V. parahaemolyticus in ceviche. The guys then tossed around some ideas for a follow up segment for when they run out of bugs for bug trivia which included using the IAFP 100 year celebration materials.

The discussion then turned to a Food Safety News articles on the NC Farm Bill and Ben thought that there might be some unintended consequences to this Bill. The guys then discussed the broader issues related to the risks of producing food, especially produce, and what this means for liability. The guys agreed that in some cases there just aren’t identifiable contributing factors, such as in the Fayetteville outbreak, and contemplated that this might differ in terms of liability compared to a case where there is clear negligence.

The focus then shifted to chickens, which was prompted by this paper in Journal of Food Safety. The rates of Campylobacter and Salmonella found on chickens purchased from farmer’s markets and supermarkets were similarly high. Don was also interested in a link shared by Andreas about raw chicken hand towel, especially because of the comments posted to it. To finish off the chicken theme the guys talked about a Salmonella Heidelberg outbreak linked to a single poultry producer. But the industry and USDA have been vewy, vewy quiet!

Ben’s watching The Newsroom again and in the after dark the guys were frustrated by their iTunes ratings and that Carl Winter and even a dog food safety podcast episode was rating higher. Ben also shared the sacrifices he has to make to get new hockey skates. The guys finished off with a trail mix inspired Best in Show, Family Tree, Launch Bar and Food Safety Talk shirts.

Food Safety Talk 40: All in on Boogers

Added on by Ben Chapman.

The guys started the show with some news and general chit chat, including hockey, an article about fighting bacteria with mucus, Linked In (perhaps the creepiest social network), Don’s Silver Beaver Award, surely a ’Major Award’, and the TV they are watching: Arrested Development, Adventure Time and Game of Thrones.

The new ‘Food is the New Rock’ podcast (suggested by fan of the show Brian Sauders - @BSauders) that provides a blend of food and music topics, reminded Ben of this Freganism barfblog article. Don then mentioned some interesting work of University of Iowa's Computational Epidemiology Group was working on, which was followed by a discussion about IAFP annual conference and IAFP PDGs.

The bug trivia segment focused on Staphylococcus aureus, which is ubiquitous in the human and animal buccal cavities. Staph produces a heat resistant enterotoxin in food, famous in part for causing the Chinese canned mushrooms outbreak. Don also noted that S. aureus poisoning was also known as Ptomaine poisoning.

The guys then talked about this SciLogs article by Matt Shipman (from Ben and Matt YouTube fame) and why people might not care about grants that have been awarded but are more interested in research outcomes.

The discussion then turned to the Salmonella Saintpaul cucumber outbreak and Ben was surprised by the lack of media coverage this outbreak created. Don noted that cucumbers generally had high microbial counts, as did other fresh produce such as tomatoes and lettuce, and he wondered why there hadn’t been more outbreaks to date. Ben was wondering whether contamination might be related to the water used in greenhouse production, which reminded Don of a recent article on bacteria in surface waters. Don pondered whether high relative humidity in greenhouses might be related to the transfer of pathogens.

The NSF’s article on the germiest kitchen items made Don and Ben so angry. They were flabbergasted by the lack of scientific rigor used in the work and in the reporting of it. The less-than-helpful food safety messages in the article reminded Don of Merlin Mann’s Old Butchers post, which mentions the ‘useful’ Lifehacker article on using soap to clean dishes.

The guys didn’t feel much better about the Consumer Reports article on ground turkey. They wondered about the low Campylobacter isolation rate and Don shared some concerns about the study that he had also discussed with Marge Perry. Ben and Don congratulated AMI on their spot on public response but they felt that the National Turkey Federation response lived up to its name.

In the after dark the guys talked about Dan Rockey’s research on Chlamydia and Don’s upcoming Brazil trip thanks to Scientists without Borders.

 

Food Safety Talk 22 – Gut demons, miniature blood Nazis, vampire nanobots and scientific reviewers

Added on by Don Schaffner.

The guys started with the usual technical problems but this time they were self-inflicted rather than Skype induced.

Don started off by talking about FSIS Risk Assessment for Guiding Public Health-Based Poultry Slaughter Inspection, which he is currently reviewing. The risk assessment is part of FSIS’ attempt to modernize their meat inspection system. Despite the introduction of HACCP in the mid 90’s, the current system relies on inspecting every carcass for visually observable contamination, obviously missing microbiological contamination, like in Gary Larson’s “Early microbiologists.” The risk assessment was undertaken to assess whether allowing FSIS personnel to undertake off-line inspection verification activities would result in reductions (or at least no increase) in the occurrence of Salmonella or Campylobacter on finished poultry carcasses.

The risk assessment is largely based on a data rich and complicated regression model, which attempts to model the prevalence of Salmonella or Campylobacter from different types of inspections activities. While ultimately nothing is clear-cut, the risk assessment does indicate that moving inspectors from on-line inspection to more risk-based off-line activities will not result in more foodborne illness. However, the coding system used in the risk assessment was turning Don into 'grumpy pants' and reminded Ben of Bingo, and it shows an apparent communication disconnect between those undertaking the modeling and those writing up the risk assessment.

The conversation then turned to FSMA and the delay in the regulations. Ben’s worried that some companies may be holding off on undertaking certain activities until the regulations come out. For example, he thinks that some business may be holding off on training staff until the training standards are better defined. Both agreed that concern for food safety and public health didn’t stop due to the lack of regulations and that any effort expended in planning and thinking about food safety is not wasted. Don is hopeful that even if the FSMA is repealed that the good ideas in FSMA will not be lost, and neither will the activities of the Food Safety Preventative Control Alliance be wasted.

Since the last podcast, Don had been to his favorite restaurant, Moosewood in Ithaca, NY while Ben started his visit to Canada with a trip to Tim Hortons to bask in the Canadian ambiance and slang, such as beauty and giver, eh? Ben also went to Swiss Chalet with his mom and dad. When a child on a nearby table  vomited, Ben’s neurotic father wanted to know whether they should move. But Ben assured him that they were OK, having ulterior motives in mind. One of the kitchen staff then came out of the kitchen to clean up the vomit with a bucket, mop and some cleaning cloths, before disappearing back into the kitchen, clearly not following CDC’s guidelines for cleaning up vomit. Ben was of course aware of the risks associated with airborne Norovirus infection as shown by his Food Safety Info Sheet and his careful reading this article. But he wanted to see how the restaurant handled the cleanup, even at the risk of his own heath and that of his parents!

On the social media front, Don recommended that Ben follow Michele Catalano and John Roderick (from Roderick on the Line) on Twitter. Don was totally in awe of Mike Batz’s Twitter-awesomeness when Mike replied to John’s tweet about the bactericidal effects of coffee with “Coffee kills gut demons, miniature blood Nazis, and vampire nanobots. But not milk devils. Everybody knows this.” Ben is again trying to engage more on Twitter, but he wasn’t impressed with McDonald’s Executive Chef’s video on how to do a Big Mac at home.

The guys then discussed scientific writing. Despite Don’s best efforts he can’t get his students to write better, though maybe collaboration with Michelle Danyluk on “How to write a paper that won’t piss off your advisor” might help. He’d even be happy if students learned to use a reference manager like Sente. Ben is trying out some advice he’d received from Gord Surgeoner during his graduate studies – with a bit of luck it’ll earn him some beers.

While Don is generally happy with his own scientific writing he wasn’t happy with the reviewer of his recent JFP manuscript entitled “Issues to consider when setting intervention targets with limited data for low-moisture food commodities: A peanut case study” which arose out of an ILSI North America sponsored meeting. The reviewer thought that the approach was very simplified and not novel enough. He clearly didn’t understand the complexities of making decisions from limited data – something the smartest people in this field in the country struggled with.

Finally, the guys got excited about the upcoming IAFP meeting, for which Don had done an IAFP webinar for students and IAFP meeting first timers, which was all about how to meet people. Don also offered to a buy a beverage of choice for any listener who mentions to podcast to Don at the IAFP meeting.

Food Safety Talk 4: Ode To A Pittsburgh (Michael Batz, Guest)

Added on by Don Schaffner.

Episode 4 of Food Safety Talk. In which Ben and Don can't mesh their schedules, so Don interviews Michael Batz, who turns out to be just as big a food safety nerd as Don or Ben. Like certain other podcasters, Batz insisted on using WiFi rather than a wired Ethernet connection as suggested by the experts. Although he promised to "sit real close" to his wireless base station, the quality of the call degrades toward the end. Don was prepared to drop in a few choice sound effects in case Mike dropped out completely, but in the end everything Mike had to say made it into the recording.
