Overuse of antibiotics in agriculture drives antimicrobial resistance globally, while masking welfare problems that should be addressed through management improvements.
Antibiotics used to prevent disease in poor conditions mask underlying welfare problems. Pigs and chickens in crowded, barren, or unsanitary conditions develop disease that is treated with medication rather than by improving conditions. This creates a cycle that simultaneously harms animal welfare and public health. Reducing antibiotic use sustainably requires improving the conditions that make animals susceptible to disease.
