Badgers are implicated in bovine tuberculosis transmission to cattle, leading to controversial culling programs. Understanding the welfare evidence and alternatives is essential for humane and effective disease management.
The badger culling debate illustrates how wildlife welfare, conservation, and agricultural policy can come into sharp conflict in ways that make straightforward welfare advocacy challenging. Badgers are social, intelligent animals with strong attachment to their territorial setts, and disruption of their social groups — through culling — causes significant welfare harm while potentially counterproductively increasing TB spread through perturbation effects. The free-shooting method approved in UK culls has faced sustained criticism from veterinary and welfare experts regarding the proportion of animals killed quickly and humanely versus those injured and surviving. The welfare-optimal approach that also achieves the policy goal of TB control points toward vaccination: injectable BCG has demonstrated 74% efficacy in field trials, eliminates perturbation effects, and imposes far lower welfare burden through capture-vaccination protocols compared to shooting. The obstacle is cost and logistical scale relative to shooting programs, not scientific efficacy. Advocating for vaccine-led badger TB policy is thus simultaneously a welfare and evidence-based policy position.
