Animal Welfare in Zoonotic Disease Emergence

Zoonotic diseases like COVID-19, SARS, and MERS emerge primarily from intensive animal-human interfaces — creating welfare crises for animals alongside public health emergencies.

Key Facts

75% of emerging infectious diseases originate in animals
Wet markets and live wildlife trade provide conditions for zoonotic pathogen emergence and transmission
Intensive pig and poultry farming creates conditions for influenza reassortment and emergence
Culling responses to zoonotic outbreaks have killed hundreds of millions of animals without anesthesia
Preventive approaches including habitat protection reduce zoonotic risk by maintaining species barriers

Welfare Considerations

Zoonotic disease emergence creates catastrophic welfare outcomes for animals caught between pathogen spread and human control responses. Mass culling of poultry during avian influenza outbreaks — frequently by carbon dioxide or live burial — kills hundreds of millions of animals in welfare-compromised conditions. Wet market closures displace trade rather than eliminating it, creating welfare and sanitation problems in new locations. Prevention through reducing high-risk human-animal interfaces is both a public health and welfare priority.

What You Can Do

Support international monitoring of live wildlife trade for zoonotic disease risk
Advocate for welfare standards in emergency culling protocols for disease control
Reduce consumption of species and systems associated with high zoonotic risk
Support habitat conservation as a zoonotic disease prevention strategy
