MSNBCAbout two years ago, dozens of workers at a large chicken hatchery in Arkansas began experiencing mysterious skin rashes, with painful lumps scattered over their hands, arms, and legs.
"They hurt real bad," says Joyce Long, 48, a 32-year veteran of the hatchery, where until recently, workers handled eggs and chicks with bare hands. "When we went and got cultured, doctors told us we had a superbug."
Its name, she learned, was MRSA, or methicillin-resistant Staphylococcus aureus. This form of staph bacteria developed a mutation that resists antibiotics (including methicillin), making it hard to treat, even lethal. According to the CDC, certain types of MRSA infections kill 18,000 Americans a year — more than die from AIDS.

Then in 2008, a new source and strain of MRSA emerged in the United States. Researcher Tara Smith, PhD, an assistant professor of epidemiology at the University of Iowa, studied two large Midwestern hog farms and found the strain, ST398, in 45 percent of farmers and 49 percent of pigs. The startling discovery — and the close connection between animal health and our own that it implied — caused widespread publicity and much official hand-wringing. To date, though, the government has yet to put a comprehensive MRSA inspection process in place, let alone fix our problematic meat-production system.
You may not have the same close contact with meat that a processing plant worker has, but scientists warn there is reason for concern: Most of us handle meat daily, as we bread chicken cutlets, trim fat from pork, or form chopped beef into burgers. Cooking does kill the microbe, but MRSA thrives on skin, so you can contract it by touching infected raw meat when you have a cut on your hand, explains Stuart Levy, MD, a Tufts University professor of microbiology and medicine. MRSA also flourishes in nasal passages, so touching your nose after touching meat gives the bug another way into your body, adds Smith.
