Food Safety Talk 33: Fresh Produce Punk Rock Hippieness

Added on by Don Schaffner.

Don starts by battling Skype again while Ben gets organized. The guys shared their favorite Starbucks coffee orders, which Don takes to go in his Marco-approved ™ Contigo travel mug. While these mugs can be challenging to wash, the guys agreed that washing them (or other dishes) in the bathroom was never a good idea. Even John Gruber knows that storing dishes in the bathroom is a bad idea, as he pointed out in a recent episode of The Talk Show. Ben then went into a coffee-fuelled rant about Getting Things Done, his favorite Canadian TV series ‘The Newsroom’The Lumineers, Bad Religion and The Wire’s Stringer Bell. Don countered with Fat Boy Slim, the Luther, Bramwell, Ripper Street, and Transmetropolitan.

After a shout-out to Renee Boyer’s Food Safety class at Virginia Tech they talked about listener Bridgette’s link to “Dear Abby - Changing baby on eatery table takes the cake” and her comment that perhaps that common sense isn’t that common at all.

Next on the agenda was a discussion of the recent CDC report on foodborne disease attribution and how fresh produce is associated with greatest amount of foodborne illness, while poultry is linked to the greatest number of deaths. Don explained how the MDP’s retail sampling results match up reasonably well with actual illness estimates, according to his crude risk assessment. Ben was looking for information on what people could do to reduce the risks, as Don recently shared on WebMD. Ben was also surprise by the amount of deaths associated with norovirus (shown in the Technical Appendix 1 of the CDC report), the majority of which are associated with nursing homes. As the guys dug deeper into the results they unearthed more questions than answers and they cautioned against blindly trusting data.  As Don learned from reading Chumbawuba liner notes.

Ben and Don then discussed the recent Food Safety News article “Does The “No Illnesses” Language Belong in Recall Notices?” and whether the wording impacts on how consumers react.

The focus then turned to the FSIS “Let's Talk Chicken” podcast. The guys found the scripted nature very difficult to connect with. Instead they found CDC’s approach in “Preparedness 101: Zombie Apocalypse” much more engaging. Don felt that passion was important in podcasting and cited the Obsession times Voice talk by Merlin Mann and John Gruber at SXSW.  Don also noted that he listens to Neutral, and his new favorite podcast, for the voice, and not the content.

In the after dark the guys chatted about using American Apparel for making T-shirts, creating Food Safety Talk Decals, iPads, Ben’s hockey obsession and 2 Little Superheroes.

Food Safety Talk 26: We’re out of the lag phase!

Added on by Don Schaffner.

Ben and Don started the podcast with a discussion about Lego. Ben has finally started his homework – watching Episode 1 from Season 1 of The Wire. This evolved into a discussion of music, including Tom Waits, Neil and Pegi Young’s Annual Bridge School Benefit Concert and the Kronos Quartet. Then Don had little Skype hiccup, which turned out to be pibcak.

The guys then turned their attention to food safety and Don started it off with a mention of Back to Work, Episode 85: "Schrödinger's Soap Holder", which focused on safely navigating a public restroom with or without hot water, soap and paper towels. After a short sports excursion, including a walk down “No-Hockey Lane” (which apparently had Michele Catalano fired up) the guys found their unique spiritual connection… through peanut butter, but not jelly.  Andreas suggested Aussie Rules in the event there is no hockey.

The discussion then focused on the current peanut butter related illness outbreak and related recalls. Ben wondered allowed how a regulatory agency might determine the period of production that is to be recalled. Don guessed that it was related to the company being able to document the last comprehensive cleanup. A potential difficulty for this relates to the use of rework, as seen with the ever-expanding Hudson beef recall. While knowing how recall decisions are made may not be of interest to everyone, but Ben noted that this information would be useful to other companies who face recall decisions in the future.

Ben then asked about the magnitude of the risk of Salmonella in peanut butter as he hadn’t seen any published risk assessment. Don guessed that it was low (relative to many types of produce) because the Microbiological Data Program 2009 data summary didn’t show any Salmonella detections in 1542 peanut butter samples. Don then raised the issue that the MDP recalls were never or rarely linked to outbreaks. He was particularly interested in this because of an upcoming talk he was preparing, in which he combined prevalence estimates from the MDP 2009 data, under-reporting estimates from the Scallan et al article, and a rough dose-response estimate. Don’s reasoning indicates that it’s not surprising that the MDP program would result in detections (and hence recalls) that aren’t linked to outbreaks.

Using the example of cilantro, which had many detections of Salmonella reported in the 2009 MDP data, Ben noted that he would really like to know more about where and how the hazard is introduced into the product. Don then suggested that a better way of reporting the MDP results would be to report the positive rate, rather than just the number of positives, as clearly the denominator is important.

Ben then mentioned the current large norovirus outbreak in Germany, where more than 8400 children have shown symptoms. Ben hypothesized that it might be related to water in a fresh produce washing and packing plant.  Turns out he might just be right since frozen strawberries have now been implicated. Ben wasn’t sure whether a surveillance program like the MDP would ever detect viruses in fresh produce, and while he accepted the utility of the MDP he was also sure that it could be improved.

Ben then discussed his recent experience of visiting Jeanne Gleeson, Barb Chamberlain and their army of programmers, who produced Ninja Kitchen. He was talking to them about producing stop motion animations to illustrate how and where hazards are introduced into the fresh produce supply chain – from farm to the consumer. Ben is keen on using these for educational presentations to producers as well as consumers shopping at farmers markets. This reminded Don of the norovirus cross-contamination modeling work his student Di Li is working on, and also the excellent videos of Jim Mann from Hand washing for Life.

Then Don offered to send a free FoodSafetyTalk.com fridge magnet/thermometer to listeners who contact him via email or Twitter. He’s also using them for distribution at MaxFunCon East with the aim of increasing listener numbers, which has just exited the equivalent of the bacterial lag phase.

In the After Dark Ben announced that he was going to watch some more of The Wire and then proceeded to assign Don some homework – to watch Canadian TV Series "The Newsroom".

Food Safety Talk 26: We're Out Of The Lag Phase!

Food Safety Talk 23: Hello? Hello? Stalkers? Or closing the barn door after stepping on the cat

Added on by Ben Chapman.

Season 2 kicked off with the introduction of special guest stalker Chip Manuel who joined the guys from the Dan Benjamin style box in Ben’s office to provide a student perspective of IAFP.

The discussion started with an IAFP meeting round-up, including some discussion of the official app (iPhone or Android) and why Ben was hiding from his ‘stalkers.’ Chip and Ben both loved how the app gave them the schedule in the pocket, but noted a few minor annoyances. Don was pleasantly surprised how many people at the meeting had used the app.

At IAFP, Chip chaired the student Professional Development Group (PDG) and helped organize the student luncheon, at which Don presented. Don felt somewhat unloved, since none of the students came up to him during the conference to say “Hi” afterward (even after offering free drinks), but Chip questioned why Don hadn’t joined the students at Karaoke. Ben didn’t have the same problem as Don, so maybe students are intimidated because Don is the IAFP president. However, Ben felt that there were few non-students to mix with during the IAFP Student Mixer and maybe a speed networking between students and professionals will take place next year.

Ben didn’t go to any symposia or round-tables unless he was presenting in them, because he concentrated on the technical talks to find really new, fresh and interested things. Don noted that the “clicker” audience feedback was really useful and Ben enjoyed the clickers from a speaker’s perspective as it helped shape the talks on the fly.

The guys then explored their paranoia for double booking themselves for talks. This reminded Ben of a talk he gave on “Using multiple media and messages to create and foster a good food safety culture” in Tennessee. After the talk he was stumped by an audience question about a rumor that Ben had floated his Fanny down the Ganny, which was related to a festival in Port Hope.

The discussion then turned to follow up. Ben forgot his homework to watch “The Wire” as he’d been watching the Olympics. The conversation turned to the Olympics and sports more broadly and Ben recalled some watching a women’s soccer game  while working at a bar.

Related to the vomit incident discussed in the previous podcast, third biggest fan, Mike Roberson sent a message asking whether Ben offered some food safety suggestions with Swiss Chalet. Ben noted that he hadn’t, but that it would involve sectioning off the contaminated area and avoiding moving contaminated mops, buckets and staff back into the kitchen area. This led to Chip providing some information about his scientific background and his current work on Norovirus nested PCR assays with Lee-Ann Jaykus. Chip agreed with Ben’s approach for dealing with the vomit incident. In particular he mentioned the importance of separating the clean-up from food preparation and also the need to use validated decontaminants to inactivate Norovirus.

The guys the explored their scientific family trees. In particular, Chip’s scientific grandfather is Martin Videman, which makes Karl Batt his scientific great-grandfather and Myron Solberg is great-great grandfather.

Ben then raised an issue he became aware of as part of his involvement with North Caroline Fresh Produce Safety Taskforce. Listeria monocytogenes had been found on cantaloupes though MDP surveillance, though no illnesses had been reported. Product was tracked back to Burch farm and cantaloupes were recalled over a number of days. Ben posed some questions about what such a recall says about production practices, especially in comparison to the Jensen’s farm outbreak last year. He also wondered whether cantaloupes were in a different risk category compared to other fresh produce. Don thought that Listeria would be found on other fresh produce and that cantaloupes clearly are a risk (as seen from last year’s outbreak – though there were apparently a number of processing issues). But at the same time he cautioned that to understand the risk better one would need to know the levels and how growth of Listeria might occur. Chip hadn’t found much Listeria in soil as part of his Master’s Thesis, despite Listeria having been reported as “ubiquitous” in soil. However, this discrepancy may be related to specificity issues with the diagnostic methods previously used, such as the simplified Henry technique. Ben felt that cantaloupes, and watermelon, do belong into their own risk category as they are grown on the ground, but unlike other produce they are eaten raw and can support the growth once they are cut. In addition, after cutting they are often stored for a number of days at temperatures that will promote the growth of Listeria.

The FDA had described Burch farm as having unsanitary conditions, but Don questioned whether other farms would actually be similar and whether this is in fact a risk factor for a fresh produce farm. Don then wondered whether it’s “blaming consumers” when the increase in risk comes from the practices in the home, i.e. storage, temperature and handling. And what is the solution to this? Is it the farmer’s or retailers responsibility to produce a Listeria-free cantaloupe or would an education campaign on proper storage and usage be more effective? And what would that proper storage be? Don also floated his pipe dream of retailers being able to avoid recalling food products because they are doing an excellent job at educating their consumers (of the risks). Chip found it interesting that all five Listeria isolates stored as part of the MDP program, were linked to human isolates on PulseNet and he wondered what would happen for this recall.

Don then gave kudos to Evan Henke for some cryptic tweets that managed to confuse Mike Batz. He also recalled how impressed he was when he shopped at Shaw’s supermarket, because they provided wipes for sanitizing hands and shopping cart handles. He was even more impressed by the public food safety announcement in the store that color was not an indication of doneness.  Ben then recalled some work by Sandy McCurdy on emotion-based messaging in retail stores for thermometer usage.

The guys then discussed three pieces of Don’s follow up. First was an article on eco-contamination in hotel rooms from which Ben learned not to lick the light switch or TV remote, though noodling for catfish seems to be OK. The guys then discussed an article by Dr David Acheson on the intersection of food safety and politics, which reminded Ben of Creekstone’s request for 100% BSE testing. But Don warned of the danger that regulators need to watch out for, namely that increased food safety standards aren’t used as non-tariff trade barriers. The final piece of follow up related to the discussion in the last podcasts on visual inspection of chicken carcasses. The guys are still wondering how an inspector can see anything on a chicken carcass that they have a third of a second to thoroughly examine and Don got grumpy at the chicken processor who didn’t want to be responsible for the food safety of the chicken he produces.

The guys finished off with a quick chat about their crazy upcoming travel schedules. Ben mentioned his involvement in the development of a ‘video game’ for farmers markets, which reminded Don of testing the beta version of Ninja Kitchen.
