Antibiotic Resistance and Animal Welfare: 2025 Update
The global antibiotic resistance crisis and animal welfare reform are deeply intertwined — poor welfare conditions in livestock farming drive antibiotic overuse, while reducing antibiotic use requires welfare improvements that reduce the disease burden making antibiotics "necessary." In 2025, the One Health framework is finally aligning these agendas in policy.

The Welfare-AMR Connection
Antibiotic overuse in livestock is not an isolated technical problem — it is directly caused by welfare-compromising farming conditions. Animals kept in poor conditions require antibiotics to survive at high densities. Understanding this connection is fundamental to both effective AMR policy and animal welfare reform:
How Poor Welfare Drives Antibiotic Use
High stocking density: Overcrowded animals are more stressed, immunocompromised, and exposed to pathogens — requiring prophylactic antibiotics to prevent epidemic disease spread
Stress-induced immunosuppression: Chronic stress from confinement, social disruption, and pain impairs immune function, increasing susceptibility to infection
Barren environments: Animals in barren environments develop behavioral abnormalities (tail-biting in pigs, feather-pecking in hens) causing wounds that become infected
Selective breeding extremes: Fast-growing broilers and high-yielding dairy cows have elevated disease susceptibility requiring medical management
Key Insight: Improving welfare conditions — reducing crowding, providing enrichment, addressing breeding extremes — directly reduces the disease burden that makes antibiotics "necessary." Welfare reform is AMR reform. This convergence is increasingly recognized in One Health policy.

EU Regulation 2019/6: The Gold Standard
The EU's Veterinary Medicines Regulation (2019/6), fully implemented in 2022, prohibits:
Prophylactic (preventive) antibiotic use in groups of animals where disease is not diagnosed
Metaphylactic (mass) treatment except under strict conditions
Use of critically important antibiotics for humans as first-line veterinary treatments
Importation of food produced with routine antibiotic use that would be illegal in the EU
The import provision is particularly significant for animal welfare — it creates pressure on non-EU producers supplying the EU market to improve welfare conditions that drove antibiotic use.
Measurable Progress: EU member states have collectively reduced antibiotic use in livestock by over 40% since 2011. Countries like the Netherlands, Denmark, and Belgium — formerly among the highest users — have achieved dramatic reductions through farm-level targets and welfare improvements.
Alternatives to Antibiotics: Welfare Dimensions
Reducing antibiotic use requires alternatives. The welfare implications of different alternatives vary significantly:
Welfare-Positive Alternatives
Improved housing and husbandry: Reducing density, improving ventilation, providing enrichment — directly improves welfare while reducing disease
Vaccines: Prevention of specific diseases without the welfare compromise of treating chronic conditions
Phytogenics/botanicals: Plant-derived additives that support immune function without AMR risk
Probiotics/prebiotics: Gut health support that reduces need for antibiotic gut treatment
Welfare-Neutral or Complex Alternatives
Bacteriophage therapy: Promising; welfare-neutral if effective
Early disease detection technology: Sensors and AI that detect illness earlier, enabling targeted treatment — reduces unnecessary antibiotic use while improving individual welfare
Organic acids: Feed additives that can cause discomfort at high concentrations
The One Health Framework in 2025
The One Health approach — recognizing that human, animal, and environmental health are interconnected — has gained significant policy traction in 2025. The UN Quadripartite (WHO, FAO, UNEP, WOAH) AMR action plan now explicitly links antibiotic reduction targets to animal welfare improvements, recognizing that sustainable AMR solutions require both.
National Action Plans
The majority of countries now have National Action Plans on AMR as required by WHO. In 2025, the quality of these plans has improved, with more countries including animal welfare components — recognizing that welfare improvements are one of the most effective levers for reducing veterinary antibiotic use.
Market-Driven Change
Consumer and retailer demand for antibiotic-free meat has driven significant supply chain change, particularly in the US and Europe. Major retailers including Walmart, Costco, and most European supermarket chains now have antibiotic reduction commitments for their meat supply chains. This market pressure often requires simultaneous welfare improvements — creating aligned incentives.
Business Case: Antibiotic-free production, while requiring upfront investment in welfare improvements, often reduces long-term costs through lower mortality, better feed conversion, and premium pricing. Several major poultry and pork producers have found antibiotic-free transition economically viable when coupled with welfare improvements.
Remaining Challenges
Global harmonization: Without consistent international standards, antibiotic-heavy producers undercut welfare-investing competitors
Small-scale farming: Smallholder farms in LMICs use antibiotics as a substitute for expensive veterinary care; alternative solutions must be accessible at low cost
Aquaculture: Antibiotic use in shrimp and fish farming remains largely unregulated and growing in Asia
Colistin: Used as a last-resort human antibiotic, still used in livestock in some countries despite WHO guidance
Conclusion
The convergence of animal welfare reform and antibiotic resistance policy represents one of the most powerful aligned agendas in food systems governance. By making the case that poor welfare creates the conditions demanding antibiotic use, welfare advocates can appeal to AMR concerns that resonate beyond animal welfare constituencies — reaching public health officials, medical professionals, and economic policymakers who might otherwise be indifferent to animal welfare per se.
