Farm Animal Welfare and Antibiotic Resistance

The routine use of antibiotics in farm animal production drives antimicrobial resistance that threatens both human and animal health, creating a welfare crisis that spans species.

Key Facts

Agriculture accounts for approximately 70% of global antibiotic consumption by weight
Prophylactic antibiotic use — dosing healthy animals to prevent disease — is the primary driver of resistance development
The WHO classifies several antibiotics critical to human medicine as extensively used in animal agriculture
Netherlands reduced veterinary antibiotic use by 70% between 2009 and 2020 through regulatory and industry action
Animals in high-welfare systems with lower stocking densities require significantly fewer antibiotics

Welfare Considerations

Antibiotic resistance is both a consequence of poor farm animal welfare and a threat to future animal welfare. Intensive systems create conditions where disease spreads rapidly, requiring antibiotic intervention. But antibiotic overuse erodes the drugs that treat bacterial infections in both animals and humans — meaning future animals may suffer from infections that were once treatable. This feedback loop — poor welfare requiring antibiotics, antibiotics driving resistance, resistance reducing treatment options — makes antimicrobial stewardship inseparable from welfare improvement. Countries that have reduced agricultural antibiotic use have done so by addressing the underlying welfare and management conditions that create demand.

What You Can Do

Choose meat, dairy, and eggs from producers with published antibiotic stewardship commitments
Support legislation restricting prophylactic antibiotic use in farm animals
Advocate for welfare standards that reduce disease pressure and antibiotic dependency
Engage with food companies about their antibiotic reduction targets and progress
