Overuse of antibiotics in farm animals creates antibiotic-resistant bacteria that harm both human and animal health. Reducing antibiotic use while maintaining animal welfare requires systemic improvement.
Antibiotic stewardship and animal welfare are deeply connected. High-welfare farms use fewer antibiotics because animals living in appropriate conditions with good nutrition and enrichment have better immune function and lower disease rates. Prophylactic antibiotic use is a management shortcut that compensates for inadequate housing and overcrowding rather than solving underlying welfare problems. Removing prophylactic antibiotics without addressing their root causes — poor housing, overcrowding, stress — causes welfare harm through untreated disease. The virtuous cycle runs the other way: improve welfare, reduce disease, reduce antibiotics, improve food safety. This alignment of antibiotic stewardship and animal welfare makes both goals simultaneously achievable through investment in high-welfare systems.
