cmonforton | November 10, 2014It’s been five years since the American Federation of State, County and Municipal Employees (AFSCME) petitioned OSHA for a regulation to protect workers from infectious diseases. This week, OSHA will be taking a major step toward proposing such a rule. The agency and the Small Business Administration (SBA) will be convening a meeting of 50 representatives of small organizations (i.e., small businesses, not-for-profit organizations not dominant in their field, and local governments serving less than 50,000 residents) that would likely be affected by an OSHA infectious disease regulation. Such…

kkrisberg | July 12, 2013In a recent study comparing workers at industrial livestock operations and those employed at antibiotic-free livestock operations, researchers found that industrial workers were much more likely to carry livestock-associated strains of drug-resistant Staphylococcus aureus, more commonly and scarily known as MRSA.
First, it's important to note that both groups of workers had a similar prevalence of S. aureus and methicillin-resistant S. Aureus (MRSA); however, it was overwhelmingly workers at industrial livestock operations, sometimes known as concentrated animal feeding operations or CAFOs,…

Scientists from Wuhan University in China have discovered compounds in scorpion venom that may be the next new treatment for methicillin-resistant Staphylococcus aureus (MRSA) bacteria and potentially other antibiotic-resistant microbes. Specifically, the peptide BmKn2 was isolated from Mesobuthus martensii and modified into another peptide, Kn2-7 which increased the natural antibacterial properties of BmKn2 while at the same time reducing the risk for hemolysis (destruction of red blood cells).
The new peptide, Kn2-7 was…

On Aetiology, Tara C. Smith shares the results of her latest study into methicillin-resistant Staphylococcus aureus. She and her team "looked at not only conventional meats, but also 'alternative' meat products" labeled "raised without antibiotics" or "raised without antibiotic growth promotants." Smith writes, "In our previous paper, we found MRSA on 1.2% of 165 meat samples. In the current study, we found a higher prevalence—6.6% of 395 samples were contaminated with MRSA." She believes the current, higher number more accurately reflects the…
tsmith | January 19, 2012Back in November, I blogged about one of our studies, examining methicillin-resistant Staphylococcus aureus (MRSA) in Iowa meat products. In that post, I mentioned that it was one of two studies we'd finished on the subject. Well, today the second study is out in PLoS ONE (freely available to all). In this study, we focused only on pork products, and included 395 samples from Iowa, Minnesota, and New Jersey. We also looked at not only conventional meats, but also "alternative" meat products. Most of the latter were products labeled "raised without antibiotics" or "raised without antibiotic…
tsmith | November 9, 2011I've blogged previously on a few U.S. studies which investigated methicillin-resistant Staphylococcus aureus in raw meat products (including chicken, beef, turkey, and pork). This isn't just a casual observation as one who eats food--I follow this area closely as we also have done our own pair of food sampling investigations here in Iowa, and will be doing a much larger, USDA-funded investigation of the issue over the next 5 years.
Let me sum up where the field currently stands. There have been a number of studies looking at S. aureus on raw meat products, carried out both here in North…
mikethemadbiologist | August 24, 2011By way of Matthew Yglesias, we read that,over at National Review Online, Kevin Williamson claims progressives only care about science as a way to wage culture war (yes, coming from movement conservatives, that's rich):
There are lots of good reasons not to wonder what Rick Perry thinks about scientific questions, foremost amongst them that there are probably fewer than 10,000 people in the United States whose views on disputed questions regarding evolution are worth consulting, and they are not politicians; they are scientists. In reality, of course, the progressive types who want to know…
tsmith | August 11, 2011Over at White Coat Underground, Pal has the post that I've been meaning to write. Earlier this summer, a family member posted on Facebook that a friend of her daughter was nursing a "nasty spider bite" that she got while camping in Michigan. Her post claimed it was a Brown Recluse bite. Being my usually buttinski self, I posted and told her that it was really, really unlikely to be a brown recluse bite, and that the friend-of-the-daughter-of-the-relative should hie thee to her physician and get the "bite" checked out. I told her that rather than a spider bite, it could be a Staph infection…
tsmith | June 17, 2011As I mentioned previously, I'm heading up organization of this conference, which will take place September 8-11 in Washington, DC. The abstract submission deadline has just been extended another week until next Friday, the 24th, so there's still time to send in an abstract. Hope to see many of you in September!
tsmith | June 12, 2011Nick Kristof has an op/ed in today's NY Times noting some sober statistics about the food we eat: that it puts 350,00 people in the hospital and kills 5,000 in the U.S. every year. He also cites three of our papers examining MRSA and swine/swine facilities.
tsmith | June 3, 2011...when it contains a weird gene conferring methicillin resistance that many tests miss.
Methicillin-resistant Staphylococcus aureus (MRSA) has become a big issue in the past 15 years or so, as it turned up outside of its old haunts (typically hospitals and other medical facilities) and started causing infections--sometimes very serious--in people who haven't been in a hospital before. Typically MRSA is diagnosed using basic old-school microbiology techniques: growing the bacteria on an agar plate, and then testing to see what antibiotics it's resistant to. This can be done in a number of…
tsmith | May 13, 2011It's been not even a month since the last paper looking at MRSA in meat, and up pops another one. So far here in the US, we've seen studies in Rhode Island (no MRSA found); Louisiana (MRSA found in beef and pork, but "human" types: USA100 and USA300); the recent Waters et al study sampling in California, Florida, Illinois, Washington DC, and Arizona, finding similar strains (ST8 and ST5, associated with USA300 and USA100, respectively). Now a new study has collected MRSA samples in Detroit, collecting 289 samples from 30 retail stores in the city.
For this study, they collected only beef,…
tsmith | May 12, 2011An ahead-of-print paper in Emerging Infectious Diseases is generating some buzz in the mainstream media. While the findings are interesting, I'm honestly not sure how they got published, being so preliminary.
Like many areas, Vancouver, British Columbia has seen a jump in the prevalence of bedbugs. After finding impoverished patients infested with the bugs, researchers decided to collect some and test them for pathogens--specifically, methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE). So, they tested 5 bugs from 3 patients. That's it--it doesn't…
tsmith | May 10, 2011Maryn McKenna was awesome enough to take some time out of her vacation to blog about our recent ST398 paper, finding "livestock-associated" S. aureus in a daycare worker. She raised one question I didn't really address previously, regarding our participation by kids and workers at the facility (eight kids out of 168, and 24 out of 60 staff members).
(Staph screening is very non-invasive, by the way; it effectively involves twirling a long-handled Q-tip inside the front of your nostrils. Kinda makes you wonder why families would not have wanted to participate. On the other hand, since Iowa is…
tsmith | April 25, 2011Just received an email from Vector-Borne and Zoonotic Diseases saying that my recent article, The Emergence of Staphylococcus aureus ST398, will be available for free online for the next two weeks. It was submitted roughly a year ago so it's already a bit dated in this quick-moving field, but provides an overview of "livestock-associated" MRSA up to mid-2010 or so--including food-associated MRSA.
mikethemadbiologist | April 20, 2011ScienceBlogling Tara Smith has a great summary of the recent paper reporting high frequencies of multi-drug resistant Staphylococcus aureus in uncooked meat products (S. aureus is the "SA" in MRSA--methicillin resistant S. aureus, so I won't go through the whole paper here (and Maryn McKenna, as usual, had the best early report). But there are two issues I want to raise, the first being that the agricultural system can serve as a 'reservoir' of antibiotic resistance genes and resistant organisms. That is, unlike Las Vegas, what happens on the farm doesn't always stay on the farm. Tara:…
tsmith | April 19, 2011As Maryn McKenna and others have reported, a paper was released on Friday showing a high percentage of drug-resistant Staphylococcus aureus contaminating raw, retail-available meat products. There has been a lot of media coverage of this finding--so what does the study say, and what are its implications? More after the jump.
First, a bit about S. aureus itself, and why this study was carried out. Historically, Staph has been a relatively common cause of food poisoning. The bacterium produces toxins that can collect to a high level when prepared foods are left at room temperature, such as…
