FARMINGDALE - A new study shows that nearly half the meat and poultry produced in the U.S. is contaminated with a drug-resistant bacteria.The study, published in the journal Clinical Infectious Diseases, states that 47 percent of meat tested was tainted. More than half of the contaminated samples, which included beef, pork, chicken and turkey, were antibiotic-resistant. Dr. Robert Elgart, a professor of microbiology at SUNY Farmingdale, says the bacteria found in the study are generally not tested by the government."Staphylococcus doesn't give you much of a problem," he says. "You get an acute food poisoning, which means a little diarrhea that will last about a day."However, Elgart says if not purged, the toxins could remain in the body and grow uncontrollably. The best way to protect yourself against contaminants, according to Elgart, is to thoroughly cook the meat. Associated Press reports contributed to this article.
