Apparently half the meat in the US is contaminated with staph, and half of that is drug-resistant:
Researchers from the Translational Genomics Research Institute, a nonprofit biomedical research center in Phoenix, analyzed 136 samples of beef, chicken, pork and turkey from 80 brands. The samples came from 26 grocery stores in five cities: Los Angeles, Chicago, Fort Lauderdale, Fla., Flagstaff, Ariz., and Washington, D.C.
About half — 47% of the samples — contained S. aureus, the researchers reported Friday in Clinical Infectious Diseases. Of those bacteria, 52% were resistant to at least three classes of antibiotics. DNA testing suggested the animals were the source of contamination.
