Preventing zoonotic disease while protecting animal welfare requires proportionate approaches that avoid unnecessary culling of animal populations as disease responses.
Zoonotic disease response welfare harms can exceed the disease risk they are intended to address: mass culling of millions of animals during disease scares that turn out to have limited transmission risk imposes enormous welfare costs without justified benefit. The welfare case for evidence-based proportionate responses — vaccination where available, targeted culling where necessary, habitat management to reduce transmission — is both an animal welfare argument and a One Health argument. Welfare organisations have an important role in advocating for proportionate, evidence-based responses to zoonotic disease threats.
