Study: Nearly Half of US Meat Tainted With Drug-Resistant Bacteria: "(FOX News) - There may be scores of drug-resistant bacteria lurking in your grocery meat aisle.
A study Friday by the Translational Genomics Research Institute, found that Staphylococcus aureus -- bacteria that causes most staph infections including skin infections, pneumonia and blood poisoning -- was present in meat and poultry from US grocery stores at 'unexpectedly high rates.'
Researchers found 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.
For the study, researchers looked at 136 samples involving 80 brands of beef, chicken, pork and turkey from 26 grocery stores in five cities including Los Angeles, Chicago, Fort Lauderdale, Fla., Flagstaff, Ariz., and Washington, D.C.
'For the first time, we know how much of our meat and poultry is contaminated with antibiotic-resistant Staph, and it is substantial,' Dr. Lance B. Price, senior author of the study, said in a statement. 'The fact that drug-resistant S. aureus was so prevalent, and likely came from the food animals themselves, is troubling, and demands attention to how antibiotics are used in food-animal production today.'"
