This chapter reviews the clinical and public health consequences of antimicrobial drug resistance in bacteria transferred from food animals to humans. To address the clinical importance of animal-related antimicrobial drug resistance, one must review how resistant bacteria may be a cause of increased morbidity and mortality. The chapter discusses the significance of increased transmission as a result of the unrelated use of antimicrobial agents to which a pathogen is resistant. It further covers reduced efficacy of treatment and increased virulence from a public health perspective, i.e., by summarizing observational studies that address the clinical and public health consequences of animal-related resistance. The food chain contains an abundance of antimicrobial drug-resistant pathogens, including Salmonella and Campylobacter. There is growing evidence that this has significant public health consequences. Mitigation of antimicrobial resistance in food-borne bacteria such as Salmonella and Campylobacter will likely benefit human health.
