smitty777 (1612557) writes "It was assumed that the rise of the superbug Methicillin-resistant Staphylococcus aureus (MRSA) occured due to the overuse of antibiotics in hospitals — a fact which is even mentioned on the CDC website. However, new reserch from Nothern Arizona University is pointing in a new direction: pigs. According to this research, the superbug made the jump from human to porcine farms where they are given a routine course of antibiotics.
FTA: "Price, the study's lead author, said the research was "like watching the birth of a superbug — it is simultaneously fascinating and disconcerting." He said that while this strain of MRSA was discovered less than a decade ago it appears to be spreading very quickly. "Our findings underscore the potential public health risks of widespread antibiotic use in food animal production," Price said. "Staph thrives in crowded and unsanitary conditions. Add antibiotics to that environment and you're going to create a public health problem."""
