1,242 Iowa residents were tested and monitored for Staphylococcus aureus colonization or infection over a 17-month period. The study group included individuals with regular exposure to swine and urban residents for comparison.

The researchers tested for S. aureus, methicillin-resistant S. aureus (MRSA), tetracycline-resistant S. aureus (TRSA), multidrug-resistant S. aureus (MDRSA), and livestock-associated S. aureus ( LA-SA).

Of the participants, 26 percent carried S. aureus. 2.5 percent were positive for MRSA, and LA-SA was isolated from 9.8 of the participants.

The researchers concluded that swine workers are six times more likely to carry MDRSA (multidrug-resistant S. aureus) than those without swine exposure.
