Workers in the U.S. cattle industry may be exposed to antibiotic-resistant bacteria from livestock, a finding that has broad implications for occupational health, according to a new study led by a Boston University School of Public Health (BUSPH) researcher.
In the journal PLOS ONE a research team led by Dr. Jessica Leibler, assistant professor of environmental health at BUSPH, found that 3.5 percent of a sample group of beef slaughterhouse workers in the U.S. were exposed to antibiotic-resistant Staphylococcus aureus with genetic markers of livestock adaptation.
While human exposure to pigs and poultry has been associated with livestock-associated S. aureus in workers, this study was the first to document human exposure in the context of beef workers in the U.S.
Dr. Leibler said the study implies a potential role of the beef-production chain in the transmission of antibiotic-resistant bacteria to humans, noting that, “while workers are at the front lines, our findings imply risk to workers’ families, communities, and consumers of beef products.”
