Antibiotic Resistance and Livestock: A One Health Welfare Issue

Antimicrobial resistance driven by agricultural antibiotic use threatens both human and animal health. Understanding the One Health connection reveals how animal welfare and human welfare are deeply intertwined.

Key Facts

Resistance to last-resort antibiotics (colistin, carbapenem) has been linked to agricultural overuse in China, India, and Europe
The mcr-1 gene — conferring colistin resistance — spread globally from livestock through food and environmental contamination
WHO has classified AMR as one of the top ten global public health threats
Colistin was used extensively in livestock as a growth promoter before bans — resistance is now widespread globally
Animals on farms with high antibiotic use carry resistant bacteria that can transfer to farm workers and the food chain
Countries with lower livestock antibiotic use (Netherlands, Denmark, Sweden) show lower levels of resistant bacteria
Improving animal welfare — through better housing, enrichment, and stockmanship — directly reduces antibiotic pressure

Welfare Considerations

AMR is a One Health crisis that links animal welfare and human welfare in a direct causal chain. Poor animal welfare conditions create disease pressure that drives antibiotic use; antibiotic overuse drives resistance; resistance threatens effective treatment of infections in both animals and humans. The welfare improvement pathway is simultaneously the AMR reduction pathway — making animal welfare advocacy a public health argument with broad appeal. This convergence provides a powerful basis for policy change that transcends animal welfare communities.

What You Can Do

Choose animal products from producers with verified low antibiotic use and high welfare standards
Support campaigns linking AMR and animal welfare — these issues are scientifically and politically connected
Advocate for mandatory antibiotic use reporting in livestock, publicly accessible by farm and system type
Support research into vaccines and alternative disease prevention tools for livestock
Reduce consumption of animal products from intensive systems that rely on antibiotic disease management
Engage with healthcare professionals about the agricultural drivers of AMR — cross-sector awareness matters
