Study Raises Global Red Flag Regarding Antimicrobial Resistance in Animal Food Production

A study in the journal Science focuses on the global threat of antimicrobial resistance (AMR) due to overuse of animal antibiotics in food produced for low- and middle-income countries. Authors conclude, “the portfolio of antimicrobials used to raise animals for food is rapidly getting depleted, with important consequences for animal health, farmers’ livelihoods, and potentially for human health.” Highest resistance rates were observed for the most commonly used antimicrobials in animal production: tetracyclines, sulfonamides, and penicillins.  Researchers used data from 901 point prevalence surveys – a data collection tool used to identify number of infections – from low- and middle-income countries that reported antimicrobial resistance rates of common infectious microbes (e.g. E. coli, Salmonella spp.) found in animals raised for food production. Using geospatial models they produced global maps of antimicrobial resistance.  Read more....
