Livestock Antimicrobial Resistance: Welfare and Public Health Dimensions

The overuse of antibiotics in livestock farming drives antimicrobial resistance, threatening both human health and animal welfare. Reducing antibiotic use requires systemic reform.

Key Facts

Approximately 73% of all antimicrobials sold globally are used in food animals, though this proportion is declining in some regions.
In many countries, antibiotics are used routinely for growth promotion and disease prevention in healthy animals — uses now banned in the EU.
Antimicrobial resistance (AMR) is projected to cause 10 million human deaths annually by 2050 if left unchecked.
High stocking densities and poor welfare conditions in livestock farming drive antibiotic dependence by increasing disease pressure.
Animals living in poor welfare conditions have compromised immune systems that require more frequent antibiotic intervention.
The EU banned antibiotic growth promoters in 2006 and routine prophylactic use in 2022, driving significant reductions in use.
Higher-welfare farming systems with lower stocking density and better management typically use significantly fewer antibiotics.
Resistant bacteria can pass from animals to humans through direct contact, food, water, and environmental contamination.

Welfare Considerations

The link between animal welfare and AMR is bidirectional: poor welfare creates conditions that require antibiotic use, and overuse of antibiotics drives resistance that undermines future treatment capacity for both animals and humans. Improving livestock welfare — through lower stocking densities, better nutrition, environmental enrichment, and early disease detection — reduces the disease burden that drives antibiotic dependence. This means that animal welfare reform is simultaneously a public health intervention. The "One Health" framework, which recognises the interdependence of human, animal, and environmental health, provides the conceptual basis for integrating welfare improvement with AMR reduction strategies.

What You Can Do

Choose meat from production systems with welfare certifications and explicit antibiotic stewardship commitments.
Support legislative bans on routine prophylactic antibiotic use in livestock in your country.
Reduce meat consumption generally to decrease total demand on intensive livestock systems.
Support the One Health approach in political engagement and public health advocacy.
Ask food companies about their AMR and antibiotic reduction policies in their supply chains.
Support farmers transitioning to higher-welfare, lower-antibiotic production systems.
