Nearly half of the meat and poultry samples — 47 percent — were contaminated with S. aureus, and more than half of those bacteria — 52 percent — were resistant to at least three classes of antibiotics, according to the study published today in the journal Clinical Infectious Diseases.
This is the first national assessment of antibiotic resistant S. aureus in the U.S. food supply. And, DNA testing suggests that the food animals themselves were the major source of contamination.
