Overuse of antibiotics in animal agriculture threatens human health and masks poor welfare conditions. Responsible antibiotic stewardship improves both animal welfare and public health outcomes.
Antibiotic overuse in animal agriculture both reflects and perpetuates poor welfare conditions. When animals are so stressed and crowded that disease spreads rapidly, antibiotics become a crutch that allows intensification to continue without addressing root causes. Therapeutic antibiotic use for sick animals is appropriate and supports welfare; prophylactic mass medication of healthy animals reflects inadequate management rather than serving animal welfare. Reducing antibiotic dependence requires improving farming conditions, which directly benefits animal welfare. Better welfare and responsible antibiotic use are aligned goals that reinforce rather than trade off against each other.
