Food safety
revere | January 18, 2009The four month old salmonella outbreak (here, here) that has already claimed at least five lives seems now to be an "ingredient" affair. The ingredient is peanut butter made in a Georgia plant of the Peanut Corporation of America (PCA) and sold to food distributors in bulk for use in institutions and not to consumers but also as as a peanut paste ingredient used other foods like cookies, crackers, cereal, candy, ice cream, baked goods or cooking sauces that are sold to consumers. As a result, CDC is now advising consumers to postpone eating products that contain peanut butter (such as cookies…
revere | January 11, 2009We are getting the first hints of a potential foodborne vehicle for the multi-state salmonella outbreak that began in September. We've seen it before:
The source of the outbreak of Salmonella [t]yphimurium that has sickened at least 400 and may have contributed to one death has been identified in Minnesota as King Nut peanut butter. Peanut butter tainted with the genetic fingerprint matching the outbreak was tested by the Minnesota Health Department. The product is suspected as the source of the nation-wide illnesses, which began showing up in September 2008 and have been documented in 42…
revere | January 9, 2009You may be surprised to learn (I was) that the US is having a large (almost 400 people) multistate (42) salmonella outbreak (S. typhimurium, often but not always associated with poultry and dairy products). So far 67 hospitalizations, with patients spanning the age spectrum (ages 1 to 103).DNA fingerprinting has established all cases are related (a common source or sources). Oh, and one more thing. It didn't just begin. Apparently it's been going on since sometime in September.
Like the plat du jour, this is the salmonella outbreak du jour. Last summer we were treated to the tomatoes-cilantro…
revere | January 8, 2009Mrs. R. and I tend to favor organic produce, just on general principles. It's a bit more expensive but compared to eating out it's nothing and we aren't such volume consumers that we can't make it up by my buying one less book a month. And while Obama's many of Obama's cabinet picks have gotten good marks, some haven't. One of the most important for consumers (and for public health) is the Secretary of Agriculture, and his nominee, Iowa's tom Vilsack, is a lousy choice. Honest advocates of sustainable agriculture are particularly dismayed, although you might not know it by looking at some…
revere | January 3, 2009Seventeen days left in the Bush administration. With the fiscal crisis it isn't clear some urgent matters will be attended to right away by the Obama folks, but one can hope. Urgent matters like getting the Food and Drug Administration back on track protecting our food supply. Consider this FDA Press Release from yesterday:
FDA Prevents Two Dairies from Adulterating Animal Drugs and Food
The U.S. Food and Drug Administration announced today that the District Court for the District of New Mexico has enjoined Do-Rene and Clover Knolls Dairies and their owners, Douglas B. Handley and Irene…
revere | December 23, 2008One can understand why a government might be reluctant to release information to the public about the list of illegal food additives it has found in food products made within its borders when you read this:
China Releases List of Illegal Food Additives
As part of its long-term effort to improve food safety, China's Ministry of Health recently made public a list of illegal food additives that have been used in food production. Among insecticides, drain cleaners, and industrial dyes are included boric acid, an insecticide that was added to noodles and meatballs to increase elasticity, and…
revere | November 18, 2008It's now two and half months since CDC and US FDA declared an end to the infamous tomatoes-no-it's-peppers salmonella outbreak of last summer. The outbreak itself was even longer: 3 months. There were some 1400 reported cases but probably many more that escaped detection. That's typical for foodborne disease outbreaks.
In case you've forgotten, here's a summary, courtesy Georgetown University's Produce Safety Project (PSP):
Although CDC and FDA initially pointed in early June to tomatoes as the cause of the outbreak based on epidemiological data, no contaminated tomato was ever found. In…
revere | November 17, 2008The team of investigative reporting team of Susanne Rust and Meg Kissinger at the Milwaukee Journal-Sentinel just keeps rolling along, this time with an amazing story about how microwave safe plastics are leaching bisphenol-A (BPA) at potentially unsafe levels. We are saying potentially unsafe because we really know little about the effects of hormone mimics like BPA except that at levels currently found in BPA containing plastics in contact with food and liquids produce biological effects in test systems and a recent analysis of a representative survey of US adults showed an association…
revere | November 7, 2008So we have more Salmonella contamination out and about. This one is in dry pet food. But it wasn't the pets that were getting the Salmonella:
Salmonella-contaminated dry pet food sickened at least 79 people, including many young children, and could still be dangerous, the U.S. Centers for Disease Control and Prevention reported on Thursday.
Even though the affected brands have been recalled and the factory in Pennsylvania closed, pet owners could still have the cat and dog kibble in their homes, the CDC said.

"Dry pet food has a 1-year shelf life. Contaminated products identified in…
revere | November 1, 2008Blogging can vary in spontaneity. Some bloggers spend a lot of effort honing individual posts, while some do a lot of "one offs" in response to rapidly changing events. A limiting form of the latter is "live blogging," essentially reporting in real time during a meeting, demonstration or particular event. In this sense blogging isn't very different than print journalism. There are stories that are quickies, just reporting some facts or acting as a stenographer for the government, a political campaign or commercial press release. Then there are the more in-depth analytical and investigative…
revere | October 30, 2008We've been keeping an eye out for the FDA's expert task force review of their own draft report on bisphenol-A (BPA; for more posts see here, here, here, here, here for other BPA posts). We previously reported to you the concern that the (outside) chair of that expert panel had a risk assessment institute at the University of Michigan that was the recipient of a large gift from one of the most vociferous proponents of BPA's safety and an ardent anti-regulatory ideologue. Whether it was a result of "working the refs" or a straightforward judgment, the panel has returned its report, concurring…
revere | October 24, 2008Everyone knows newspapers are struggling, which means cutting back on everything, including investigative reporting. So it is nice to acknowledge that there is still some wonderful reporting going on. A particular standout has been Susanne Rust, Meg Kissinger and their colleagues at the Milwaukee Journal-Sentinel, whose investigation of FDA's handling of the bispheonal A (BPA) episode has been superlative. Yesterday they hit paydirt again. The FDA is currently considering an August draft report of a task force convened last April to re-examine the safety of BPA. The draft report says BPA is…
revere | October 14, 2008 I run a fairly large research program at my University. My NIH grant, which runs in the tens of millions, pays for a lot of things, including a portion of my salary. But as Director, my salary is (alas) only a tiny portion of this complex operation, which has many senior principal investigators and core facilities, labs, research groups, post docs, students, research staff, etc., etc. The whole operation has to fit together and work. We're big but not huge. So $5 million, while accounting noise in Wall Street bailout terms, is a pretty big deal and not because of the paltry half salary I…
revere | October 13, 2008Food poisoning can be a miserable experience and sometimes you feel like you want to die rather than endure another minute of the agony, but people rarely die from food poisoning. At least for most causes of food poisoning. The exceptions are the exceedingly rare cases of botulism and the much more common occurrence of listeriosis, infection with the organism Listeria monocytogenes. Listeria is a really nasty bug and serious cases are often fatal. The most at risk are the elderly, the immunocompromised, and pregnant women, biologically immune altered, and their fetuses and neonates. Listeria…
revere | October 10, 2008The health concerns about bisphenol-A (BPA), a component of hard polycarbonate plastic, has been extended once again (see here, here, here for previous posts on BPA). BPA, a ubiquitous contaminant of human bodies, leaches from water and baby bottles, the lining of tin cans, dental sealants and many other sources. BPA also looks a lot like potent hormones, like estradiol and the synthetic estrogenic agent, diethylstilbesterol (DES), the cause of transplacental carcinogenesis in humans. So there have been plausible concerns that BPA might increase the risk of cancer in humans, especially in…
revere | October 7, 2008There's another Salmonella multistate outbreak, this one involving 12 states and, so far, 32 cases. As with the infmaous tomator and/or pepper problem during the summer, the Minnesota Department of Public Health's laboratory has been in the lead in tracking down the source. Salmonella is killed by cooking, so raw produce or cross contamination of foods eaten uncooked (like a salad) by raw meat (for example, when cut on the same cutting board) is the usual source. But if you don't cook meat (for example, you just heat them up for eating) and it has Salmonella, you could have a problem. That's…
revere | October 3, 2008I went to medical school at a time when it was still affordable. Even though it was a private Ivy League university, tuition was only $1200/yr at the start and I had a half scholarship. Room was $33/month. Still, it was a long time ago and that was still real money for some of us, so I ate dinner in the cafeteria and often made lunch by heating up a 19 cent can of Spaghetti-O's on a hot plate in my room across from the hospital. Medical school classes didn't allow much time for part time jobs, so I supplemented my income working as a guinea pig and blood donor. Whenever open heart surgery was…
revere | October 1, 2008Yesterday we noted the intricate interconnections between the physical, biological and social environments that conspired to affect the risk that a person might become infected with West Nile Virus. The same Adjustable Rate Mortgages that are part of that public health problem are at work in the spectacular collapse of the global financial system. Effects span huge scale differences, from local to global. Tight interconnections with unpredictable effects are also at work in our food supply, which now has long chains of production and supply that often combine local and global scales in one…
revere | September 29, 2008A new study of foodborne illness has just been published and has made quite a bit of news. The typical headline is something like: "Animals Farmed For Meat Are The No. 1 Source Of Food Poisoning Bug, Study Shows." That makes it sound like most cases of food poisoning are from a particular bug and that bug comes from farm animals. Although it is inaccurate, the stories beneath the headline don't do much to dispel it:
Researchers from Lancashire, England, and Chicago, IL, have discovered that animals farmed for meat are the main source of bacteria responsible for food poisoning.
They suggested…
revere | September 27, 2008The Chinese food adulteration scandal is spreading. I'm calling it a food adulteration scandal because it's not just milk any more. Products with milk derived ingredients are also suspect:
Seven instant coffee and milk tea products made in China are being recalled in the U.S. because of possible contamination with melamine, as health fears increased worldwide over the safety of Chinese dairy exports.
The Mr. Brown brand mixes are being recalled by King Car Food Industrial Co., based in Taiwan, and were made by China's Shandong Duqing Inc., the U.S. Food and Drug Administration said today in a…
