Wild Deer Disease and Welfare Management

Wild deer populations are susceptible to bovine tuberculosis, chronic wasting disease (outside UK) and Schmallenberg virus, with disease management approaches having direct welfare implications.

Key Facts

Wild deer can carry and transmit bovine tuberculosis to cattle in high-risk areas
Chronic Wasting Disease has not yet reached the UK but represents a major future welfare threat
Deer are routine hosts for louping ill ticks that also affect red grouse and sheep
Disease surveillance in wild deer populations provides early warning of emerging pathogens

Welfare Considerations

Deer with bovine TB develop progressive respiratory disease with long-term welfare costs before death. Culling to control TB in deer populations imposes welfare costs on culled individuals. Chronic Wasting Disease, if it reaches the UK, would cause severe neurological deterioration over months in affected deer. Surveillance and rapid response are the primary welfare tools for managing emerging deer diseases.

What You Can Do

Support APHA disease surveillance programmes in wild deer populations
Report any deer showing abnormal behaviour or neurological signs to APHA immediately
Advocate for strict controls on importing deer and deer products from CWD-affected countries
Back research into TB vaccination approaches for wild deer as alternatives to culling
