Researchers identify seasonal peaks for foodborne infections

Each year, thousands of pounds of food are wasted and billions of dollars in food sales lost because of recalls tied to foodborne infections. Using a newly developed approach, researchers identified seasonal peaks for foodborne infections that could be used to optimize the timing and location of food inspections. “We rely upon food producers, distributors and retailers to keep food ...

A self-cleaning surface that repels even the deadliest superbugs

A team of researchers at McMaster University has developed a self-cleaning surface that can repel all forms of bacteria, preventing the transfer of antibiotic-resistant superbugs and other dangerous bacteria in settings ranging from hospitals to kitchens. The new plastic surface — a treated form of conventional transparent wrap – can be shrink-wrapped onto door handles, railings, IV stands and other ...

New ‘jumping’ superbug gene discovered, resistant to last-resort antibiotic

While sifting through the bacterial genome of salmonella, Cornell University food scientists discovered mcr-9, a new stealthy, jumping gene so diabolical and robust that it resists one of the world’s few last-resort antibiotics. Doctors deploy the antibiotic colistin when all other infection-fighting options are exhausted. But resistance to colistin has emerged around the globe, threatening its efficacy. “This last-resort antibiotic ...

Gut bacteria byproduct protects against Salmonella

Researchers at the Stanford University School of Medicine have identified a molecule that serves as natural protection against one of the most common intestinal pathogens. Propionate, a byproduct of metabolism by a group of bacteria called the Bacteroides, inhibits the growth of Salmonella in the intestinal tract of mice, according to the researchers. The finding may help to explain why ...
