With county and state fairs occurring around the country, especially after many closed last year because of COVID-19, parents need to know about petting zoos and the danger they can present. Since it's petting zoo time, do you know how to protect your kids? Children love small animals, and petting zoos are magnets to many of them. Many state fairs and county fairs offer these attractions. Unfortunately, these animals can harbor pathogenic bacteria that can make kids very sick. The most dangerous is E. coli bacteria, which occur naturally in the guts of ruminant animals such as cows, goats, and sheep. The animals themselves do not get sick, but they shed the bacteria in their feces, where it can contaminate the animals themselves and their environment. The CDC states that from … [Read more...]
Raw Pet Food Is a Public Health Issue Because of E. coli Contamination
A study published in Microorganisms has found that feeding pets raw pet food comes with a risk of pathogenic bacteria, including Shiga toxin-producing E. coli (STEC), which can cause serious illness in humans and is a public health issue. The study evaluated commercially available raw meat-based diets (RMBDs) in Switzerland. These foods are made of uncooked raw muscle meats, organ meats, and the meaty bones of livestock or wild animals. They are mostly from the by-products of animals that are slaughtered for human consumption. The study looked at the occurrence of STEC isolated from commercially available raw pet food in Switzerland. In a recent study in the U.S., Shiga toxin-producing E. coli bacteria were identified in 4% of commercially available RMBDs. Studies demonstrating … [Read more...]
Three New Outbreaks on FDA Table: Cyclospora, E. coli, and Salmonella
Three new outbreaks were announced on the FDA Table of Outbreak Investigations: One was caused by Cyclospora, the second by E. coli O121, and the third by Salmonella Typhimurium. UPDATE: One of these outbreaks, the Salmonella outbreak, has a suspect food attached to it. In the cyclospora outbreak, at least 32 people are sick. The notice states that this number represents a subset of the total number of domestically-acquired cases of cyclosporiasis illnesses in the U.S. Traceback has been initiated, and sample analysis and testing has taken place. This is encouraging, because the FDA may know what has caused this outbreak. Stay tuned, since a recall or outbreak investigation notice may be issued soon. In the E. coli O121 outbreak, at least 15 ill persons have been identified. No … [Read more...]
Artificial Sweeteners May Increase Pathogen Damage in the Gut
A study published in the International Journal of Molecular Science looked at the effect of artificial sweeteners on gut bacterial pathogenicity. They found that artificial sweeteners may increase damage in the gut, by increasing the ability of bacteria to form a biofilm and the ability of the bacteria to adhere to, invade, and kill the host epithelium, which is the lining of the gut. Researchers demonstrated that saccharin, sucralose, and aspartame all promote pathogenic changes in two model gut bacteria, E. coli and E. faecalis, which could "worsen the effect of consuming artificial sweetener in the diet on gut health." This is important because bacteria growing in biofilms are less sensitive to antimicrobial resistance treatment and are more likely to express virulence factors … [Read more...]
Do You Know If You Are Grilling Mechanically Tenderized Beef?
With grilling season upon us and the Fourth of July holiday next week, most Americans are taking to their outdoor grills. We grill everything from chicken wings to veggies to burgers to steaks. But do you know if you are grilling mechanically tenderized beef? There are several ways of tenderizing meat: marinating, the way you cut it after it's cooked, and mechanical tenderizing. Knowing if the meat you are grilling is mechanically tenderized can make the difference between enjoying a nice meal and getting sick. And there's a lot of mechanically tenderized beef out there: 6.2 billion servings of mechanically tenderized beef are served every year on American tables. The USDA is offering tips on how to protect yourself and your family while grilling. One section of that piece … [Read more...]
