Badger culling to control bovine tuberculosis in cattle is highly contested. Understanding the welfare costs and epidemiological evidence helps inform evidence-based advocacy.
Badger culling involves shooting free-roaming animals in the field, with wounded badgers potentially dying slowly over hours or days from injuries that fail to kill immediately. The minimum licensed wounding rate is 5 percent but actual rates may be higher. Perturbation — the disruption of stable badger territories by culling — can increase TB spread by causing remaining badgers to range more widely. The welfare cost in individual suffering and family group disruption is significant, and the epidemiological evidence for culling effectiveness is weak.
