Farmed Animal Antibiotic Use and Welfare

Antibiotic use in animal agriculture intersects with animal welfare, antimicrobial resistance, and human health. Welfare improvements and responsible antibiotic stewardship are linked.

Key Facts

Approximately 73% of global antimicrobial use occurs in food-producing animals
Prophylactic antibiotic use to prevent disease in intensively farmed animals masks welfare problems rather than solving them
Welfare improvements including better housing, lower stocking density, and enrichment reduce disease incidence and antibiotic need
The EU banned prophylactic group antibiotic treatment in farm animals under the Veterinary Medicines Regulation 2022
Antimicrobial resistance threatens both animal and human medicine — welfare and antibiotic stewardship are aligned goals
Some antibiotic-resistant infections in humans originate in farm animal populations that share antibiotic resistance genes

Welfare Considerations

The relationship between antibiotic use and animal welfare is bidirectional and mutually reinforcing. High antibiotic use in intensive farming reflects welfare failures: animals in poor conditions with compromised immune systems get sick more and need more treatment. Conversely, reducing antibiotic use without improving underlying welfare conditions simply means sick animals go untreated — a different welfare failure. The productive path combines welfare improvement that reduces disease incidence with appropriate antibiotic use restricted to therapeutic treatment of individual sick animals under veterinary supervision. This approach improves animal welfare, reduces antibiotic resistance risk, and is increasingly required by regulation in progressive jurisdictions.

What You Can Do

Choose animal products certified to antibiotic stewardship standards that restrict prophylactic use
Support legislation requiring veterinary prescription for all antibiotic use in farm animals
Advocate for welfare improvements as the primary strategy for reducing antibiotic dependence in farming
Engage with retailers about their supply chain antibiotic use standards for farmed animal products
Support organizations monitoring antibiotic use in agriculture and advocating for responsible use policies
Reduce animal product consumption to decrease aggregate antibiotic use and welfare burden simultaneously
