Emerging data support the conclusion that antibiotic use in livestock contribute to resistance in foodborne pathogens such as Campylobacter and Salmonella, as well as commensals such as enterococci, with significant implications for public health. Mounting evidence supports an approach emphasizing antibiotic resistance as an ecological or ecosystem problem. Supporting this concept are studies which have identified resistant microorganisms (and the antibiotics themselves) in environmental samples. In related studies, mathematical models have been developed which highlight the importance of limiting antimicrobial use in agriculture before resistance reaches detectable levels in human populations.
