Researchers at the University of California, Davis may have discovered the building blocks of a vaccine that can protect against the effects of Salmonella, one of the most common food borne pathogens. The study is published in the most current issue of the journal Proceedings of the National Academy of Sciences, and would offer safety for millions of at risk individuals each year.

Increasingly high levels of antibiotics fed to livestock animals are causing antibiotic-resistant bacteria to become more potent, raising concerns from the Center for Science in the Public Interest via a petition to the USDA to prohibit the sale of contaminated meat and poultry.

Antibiotic-resistant bacteria is less common on poultry farms that have made the transition from conventional methods to organic farming, finds a new study published in the journal Environmental Health Perspectives.

More interesting news to ponder over a cup of coffee: new research shows that coffee and tea drinkers have lower levels of an antibiotic-resistant bacteria in their noses than non-coffee or tea drinkers.

After the FDA, CDC and USDA testified before Congress last year about a direct link between non-therapeutic use of antibiotics in livestock and antibiotic resistance in humans, the Pew Campaign on Human Health and Industrial Farming launched a grassroots movement called "Moms for Antibiotic Awareness."
