Wildlife Disease Surveillance and Animal Welfare

Wildlife disease monitoring protects wild populations and prevents spillover to domestic animals with welfare implications for both monitored and affected animals.

Key Facts

African swine fever, avian influenza, and chronic wasting disease are major wildlife disease threats monitored globally
Wild birds act as reservoir hosts for avian influenza that periodically spills over into domestic poultry
Chronic wasting disease in deer and elk is 100% fatal causing significant individual animal suffering
Non-invasive surveillance using environmental DNA and scat analysis reduces handling welfare costs
Mass culling in outbreak zones causes enormous welfare harm and is often epidemiologically questionable
Early detection enables targeted interventions that can prevent mass mortality events

Welfare Considerations

Wildlife disease surveillance is essential for protecting wild animal welfare at population scale and preventing domestic spillover. The surveillance process has welfare implications through invasive sampling. Non-invasive methods reduce this cost significantly. Early detection enabling minimal intervention is both more welfare-positive and epidemiologically effective than reactive mass culling.

What You Can Do

Support surveillance programs using non-invasive methods where scientifically feasible
Advocate for wildlife disease monitoring as public health infrastructure
Report unusual animal behaviour to wildlife health authorities
