Antimicrobial Resistance and Animal Welfare: A Two-Way Problem

Antibiotic overuse in animal agriculture drives antimicrobial resistance that threatens both human and animal health. Improving animal welfare conditions reduces antibiotic dependency in ways that benefit both.

Key Facts

Approximately 73% of all antibiotics used globally are consumed by livestock and poultry
AMR is projected to cause 10 million deaths annually by 2050 if current trends continue
Poor welfare conditions including overcrowding and stress increase disease susceptibility, driving antibiotic use
Countries that have banned growth-promoter antibiotics have reduced overall use without production losses
The Netherlands reduced veterinary antibiotic use by 68% between 2009 and 2019 through welfare and hygiene improvements
Antibiotic-resistant infections already cost the US economy over 5 billion annually
Welfare improvements including reduced stocking density, better ventilation, and enrichment reduce disease rates

Welfare Considerations

The link between animal welfare and antimicrobial resistance is bidirectional and important. Poor welfare conditions stress animals and impair their immune systems, creating disease pressure that is managed with antibiotics. Better housing, lower stocking densities, enrichment, and reduced transport stress reduce disease incidence, decreasing antibiotic dependence. Improving animal welfare is therefore not just an ethical obligation but a public health strategy that reduces AMR pressure while directly benefiting the animals whose conditions are improved.

What You Can Do

Choose meat from producers certified as using antibiotics only for therapeutic treatment of sick animals
Advocate for national policies banning routine antibiotic use in healthy animal herds
Support welfare certification schemes that set stocking density and enrichment standards reducing disease risk
Push food companies to adopt supply chain antibiotic policies with independent verification
Share information about the welfare-AMR connection to build coalitions between animal welfare and public health advocates
