An article in the New York Times today suggests a link between MRSA and pig farming or pork. A doctor in Camden, Indiana, a small town surrounded by hog farms, found a startling number of MRSA cases, and made the link between the hog farms and the infections. He was ready to go public with the insinuations when--he died, at age 54, of a heart attack presumably (though no autopsy was done). Five years ago, some MRSA cases were linked to pig farming in the Netherlands, where a farming family became infected, as well as 8 of 10 of their pigs. In a study of American hog farmers, 45% were infected with MRSA. The article suggests that the antibiotic resistant infection likely developed in pigs due to prophylactic use of antibiotics in animal feed.
