Abstract
  • The growing animal reservoir of antibiotic-resistant Staphylococcus aureus is of public health concern. Industrial livestock operations are a potential source of exposure to these bacteria, which may be transmitted from animals to workers, and then to the community. To increase our understanding of occupational exposures to antibiotic-resistant S. aureus, we assessed nasal carriage of S. aureus, including multidrug-resistant S. aureus (MDRSA) and methicillin-resistant S. aureus (MRSA), among workers and household members from industrial livestock operations, antibiotic-free livestock farms, and meat processing plants in North Carolina. We found a higher prevalence of MDRSA in industrial and processing plant participants compared with antibiotic-free participants, and comparable prevalence of MRSA. S. aureus belonging to clonal complex 398 was also discovered for the first time in North Carolina. This study contributes to the growing discourse regarding the public health consequences of large-scale antibiotic use in animal production in the United States.
