Animal Welfare and Public Health: The Links

The connections between animal welfare, disease emergence, and public health are stronger than commonly recognized, with welfare improvements offering co-benefits for human health.

Key Facts

The COVID-19 pandemic highlighted the zoonotic disease risk from intensive animal markets and farming
African Swine Fever devastated pig populations in Asia, demonstrating the fragility of intensive production systems
Salmonella and Campylobacter transmission through poultry are significantly influenced by farm welfare conditions
Animals under psychological stress have compromised immune function, increasing disease susceptibility and shedding
Live animal markets combine welfare-compromising conditions with high disease spillover risk
WHO, FAO, and OIE jointly advocate for One Health approaches integrating animal welfare into disease prevention

Welfare Considerations

Poor animal welfare creates public health risks through multiple pathways: stressed animals shed more pathogens, dense confined conditions enable rapid disease spread, antibiotic overuse in stressed animals drives resistance, and wildlife-livestock interfaces in natural habitats create spillover opportunities. Improving animal welfare therefore generates direct public health benefits beyond its intrinsic ethical value. This alignment of interests provides a pragmatic argument for welfare investment that does not rely solely on ethical motivation.

What You Can Do

Support One Health policy frameworks that integrate animal welfare into disease prevention
Advocate for closure or reform of live animal markets with poor welfare and biosecurity standards
Choose animal products from farming systems with lower disease risk and antibiotic use
Back research into welfare-positive disease prevention measures in livestock and wildlife
Educate others about the public health case for animal welfare improvement
