Livestock Antibiotic Resistance: Welfare and Public Health Intersect

The overuse of antibiotics in livestock farming threatens both animal health and global public health by accelerating antibiotic resistance.

Key Facts

Approximately 70% of all antibiotics used globally are given to farm animals, not humans
Growth-promoting antibiotic use — now banned in the EU — was a leading driver of resistance development
Critically important antibiotics for human medicine including colistin and carbapenems have been used in livestock
Antibiotic resistance genes can transfer from livestock to human pathogens through multiple pathways
Higher welfare farming systems that reduce disease incidence require significantly less antibiotic treatment
Denmark and the Netherlands have achieved major reductions in livestock antibiotic use through regulation and farm improvement
Antibiotic alternatives including vaccines, probiotics, and better management reduce use when implemented systematically
Animals that require repeated antibiotic treatment are often experiencing chronic welfare problems that generate the need

Welfare Considerations

The connection between antibiotic use and welfare is bidirectional. Animals in poor welfare conditions — overcrowded, stressed, malnourished — have compromised immune function and require more antibiotic treatment. Antibiotic overuse then drives resistance, making future infections harder to treat, creating worse welfare outcomes in a vicious cycle. Farms with high welfare standards consistently use fewer antibiotics because their animals are healthier. The public health dimension amplifies the ethical case for high welfare farming: the downstream harm of antibiotic resistance extends far beyond the farm gate to human medicine globally. Reducing antibiotic use through welfare improvement is both a farm animal welfare intervention and a global health contribution.

What You Can Do

Choose meat from farms certified under standards that restrict routine antibiotic use
Support policies that ban use of antibiotics important to human medicine for growth promotion in all countries
Advocate for mandatory antibiotic use reporting by farm operators in your country
Support investment in antibiotic alternatives including vaccines and improved livestock management
Reduce meat consumption overall to lower demand for products from high-antibiotic-use systems
Follow the work of ReAct and AMR Alliance for updates on antibiotic resistance and livestock policy
Engage with your elected representatives on the importance of strong antibiotic stewardship legislation
