The ecology of antibiotic resistance on farms is complicated. Animals receive antibiotic doses in their food and water, for reasons of growth promotion, disease prophylaxis, and treatment. Other chemicals in the environment, such as cleaning products or antimicrobial metals in the feed, may also act as drivers of antibiotic resistance.
