Food Safety Talk 39: Des Moines is Known for their Scallops

Added on by Don Schaffner.

The guys start by answering a question from listener Tom (whom Ben met at the Consumer Federation of America National Food Policy conference) and his request for guidance on research areas in food safety. Don’s advice was that Tom should follow his passion and from there pick a university or faculty member. This then turned into a broader discussion about education, with a focus on distance and online learning.

Don then talked about his attendance at ISGP’s  Food Safety, Security, and Defense: Focus on Technologies and Innovations conference in Verona, Italy, which operates under the Chatham House Rules (not to be confused with the Cider House Rules). Don really enjoyed the discussions between the scientific experts and policy makers and he enjoyed meeting Lynn Frewer. Don also talked about his recent visit to GOJO with his student (and some times listener Dane Jensen) to discuss Dane’s PhD research.

In the Bug Trivia segment, Ben talked about Clostridium botulinum, the ‘sausage poisoning’ bug, and Ben’s recent Barfblog post on the topic. The guys thought that tin-foiled potatoes caused unnecessarily large concern because of one outbreak, as most botulism cases are linked to ineffective home canning practices. While Ben had trouble pronouncing nitrosamines, he challenged Andreas to find papers by Gibson and Roberts on Clostridium and cured meats. Andreas did not disappoint, finding Factors controlling the growth of Clostridium botulinum types A and B in pasteurized, cured meats parts I, II, III, IV, V, and VI.

The guys then talked about the Egg Rollie, as Aaron "you-SUE-ghee" wanted to know whether the cooked ‘egg rollie’ could be contaminated by raw egg as it rises. Ben wasn’t too concerned and Don pointed out that while there was a risk, the risks of illness from eating raw eggs were rather low.

The conversation then turned to the Listeria and cantaloupes, as FDA was planning to undertake a survey of Listeria monocytogenes in US cantaloupe packing houses. Ben has been organizing industry workshops with Chris Gunter (guest in FST episode 3) and some others. Ben explained what he would do if he was a producer and FDA were about to visit his packing house for sampling. Don agreed with Ben’s strategy and pointed out that baseline information on pathogen prevalence on produce was needed. However, the guys couldn’t understand why the samples were not also going to be tested for Salmonella, which had been involved in more cantaloupe related outbreaks than Listeria. In addition, Don wasn’t convinced that this survey was the best use of public funds. This reminded Don of a USA Today article on sequestration which included a Doug Powell quote, which Don also posted on his Tumblr.

Ben sent a shout out to Ashley Chaifetz, a PhD student studying public policy, who wrote a Barfblog post on Salmonella in dog food (and this follow up post) and how she now longer trusted the dog food manufacturer. Finally the guys sent a big thank you to the folks at SHS Design who updated their FST logo for iTunes.

In the after dark the guys talked about a couple of iTunes comments, their usual scheduling challenges, a potential guest, "Rappaz R.N. Dainja” and Science Online.

Food Safety Talk 24: Bagel tongs for twenty, Bob!

Added on by Don Schaffner.

Today’s guest was Mike Batz, um, Joe Smith, who Skyped in from a hotel room while emptying the mini bar. Ben still hasn’t done his homework from last Season – watching The Wire. And to Mike's disappointment Ben hasn’t even watched The Lego Wire. The discussion then turned to playing with Lego, Ben’s vandalism activities as a teenager, craft paper maze making, Dungeons and Dragons and The Wire characters' D&D alignment.

The guys then got serious about food safety and discussed the Salmonella Typhimurium outbreak that CDC has linked to cantaloupes. At the time of the recording, the FDA hadn’t specifically commented on the potential source, though Chamberlain Farms had begun recalling cantaloupes. The guys thought it was strange that no FDA/CDC update on the situation has been issued for days and the overall lack of communication around this outbreak. However, Don noted that the lawyers are getting their ducks lined up and Bill Marler had already blogged about a lawsuit. Don asked Ben whether there is ever a right time to say nothing in a case like this. Ben didn’t think there was, but suggested that there was a right time to say “we’re uncertain” instead. He recalled the discussion mentioned in FST episode 6 about an outbreak of E. coli O157:H7 associated with the North Carolina State Fair, where the North Carolina Division of Public Health updated the information of what was known on a daily basis. Ben thought that this was better than the five-day cone-of-silence.

Mike was bothered by regulators implicating a whole growing region or commodity rather than naming the implicated farm, especially since the farm had already initiated a recall. It reminded him of what happened to Florida tomato growers a few years ago. Mike pointed out that implicating a whole region does not provide any incentive to an individual farmer to follow GAPs and do the right thing – since a neighbor who doesn’t do the right thing could wipe out all that effort.

In contrast, the Burch Farms recall, which was initiated after Listeria was detected on cantaloupes, but without an outbreak having occurred, did not result in the same level of concern. But Ben noted that the Burch Farms recall nevertheless resulted in questions being raised by buyers and cancellations of contracts, and as such the recall still impacted on the whole industry.

Don noted the fundamental differences between Listeria and Salmonella. He reminded the guys that the risk depends on the dose and that the dose-response relationship differs between the two organisms. Ben also noted the problem of applying a zero tolerance standard for ready-to-eat-foods to these agricultural commodity products, and Don highlighted the need for quantification when testing in addition to simple presence/absence testing.

Ben then explained the differences in the post harvest systems between California, where cantaloupes are not washed, compared to North Carolina, where cantaloupes are regularly washed. He noted that the use of water might provide an opportunity for cross contamination, which Don totally agreed with. The discussion then turned to Ben explaining that cantaloupes are washed because that’s what the industry has always done, though his experience indicates that farmers might be open to re-engineering their processes.

Don then produced a smorgasbord of potential topics for discussion and the guys settled on a 2002 blog post by John Gruber about Bagel Tongs on Fedora Review. In the article Gruber worried about bagels and that the “tong-arms are covered with some sort of moist, brown sediment.” Ben agreed with Gruber and would rather use tissue paper to pick up the bagels, though mainly because he feared contracting Norovirus from the tong handles. Don agreed with Ben that it’s not the crap at the end of the tongs, but the crap you can’t see that’s the problem. He also recalled that some cruise liners have a norovirus risk reduction measure, which involves staff serving passengers at the self-serve buffet on the first three days of the cruise.

Ben then reminisced about his high school days, when he wasn’t vandalizing his neighbors’ backyards but when he was working in a bulk food store. He had to clean and sanitize the scoop on a weekly basis, though he actually did this only when the prunes got really gunky. He never sanitized the handles – got to hold on to something while washing the scoop. Mike thought that the epidemiological evidence, that placed Ben at the epicenter of foodborne illness outbreaks, was building.

The show finished by Don telling the guys about wanting to order some Food Safety Talk promotional refrigerator temperature sensing magnets for inclusion in the MaxFunCon EAST show bags.

By now Mike Joe had sobered up somewhat and was eyeing the Arrogant Bastard that he’d been contemplating and this evolved into a broader discussion of alcohol consumption patterns.

In the after dark the guys talked about a range of “stuff” including Mike’s five-day FAO/WHO meeting bender on foodborne parasites in Rome.

Food Safety Talk 5: A Medley of Fleetwood Mac

Added on by Ben Chapman.

Don and Ben are back in the same time zone and talk a lot about cantaloupe. The episode starts off with a bit of nerdy discussion about Apple products and upgrading to iOS 5. But then the guys talk about food safety, outbreak investigations, social media and messaging. The podcast is available here.

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.
