Antimicrobial Resistance and Animal Farming: A Public Health and Welfare Crisis

Routine antibiotic use in livestock farming drives antimicrobial resistance, threatening both human health and the ability to treat animal diseases — creating a feedback loop of welfare harm.

Key Facts

Approximately 70–80% of all antibiotics used globally are administered to livestock, predominantly for growth promotion and disease prevention rather than treatment of specific infections.
The WHO has designated antimicrobial resistance (AMR) a top global public health threat; AMR already causes approximately 1.3 million deaths annually worldwide.
Resistant bacteria originating in livestock farms transfer to humans through food, environmental contamination, and direct contact, and are documented in all major producing countries.
The EU banned antibiotic growth promoters in 2006; subsequent reduction in human AMR linked to livestock reservoirs has been documented in multiple studies.
Animals suffering from untreatable antibiotic-resistant infections experience prolonged illness and pain that effective antibiotics would have prevented.
Improved housing conditions, vaccination programmes, and biosecurity measures can reduce the need for antibiotics without compromising animal health outcomes.

Welfare Considerations

The AMR crisis creates a direct welfare feedback loop: overuse of antibiotics to compensate for poor housing conditions creates resistance that then renders those antibiotics ineffective for treating genuine animal disease. Future generations of farmed animals will suffer from infections that cannot be treated — a welfare consequence of today's agricultural practices. Beyond future harm, current antibiotic use in farming often masks underlying welfare problems (overcrowding, stress, poor nutrition) rather than addressing them. Reducing antibiotic use by improving farm conditions simultaneously improves current animal welfare, reduces AMR development, and protects the effectiveness of medicines needed to treat sick animals.

What You Can Do

Choose meat and dairy from producers that have committed to antibiotic stewardship policies and report antibiotic use data.
Support legislation banning prophylactic antibiotic use and growth promotion in livestock farming.
Reduce consumption of animal products from intensive systems where prophylactic antibiotic use is prevalent.
Advocate for mandatory antibiotic use reporting by farms to enable monitoring and enforcement of reduction targets.
Support research into alternatives to antibiotics in livestock farming, including vaccination programmes and improved housing.
