The use of antibiotics in farm animal production to compensate for poor welfare conditions creates a feedback loop where animal suffering and human health risk reinforce each other.
The antibiotic resistance crisis and farm animal welfare are deeply interconnected. Crowded, stressful, barren environments produce sick animals that require antibiotic treatment. The welfare failure generates the antibiotic dependency. Farms operating with higher welfare standards — lower density, enriched environments, better ventilation — demonstrate consistently lower antibiotic use because healthier animals need fewer interventions. Improving farm animal welfare is thus simultaneously an animal welfare and a public health intervention.
