Badger Welfare: Culling Controversy and Bovine TB

Badger culling in the UK has been a major welfare and policy controversy. Understanding the evidence on bovine TB transmission and humane alternatives illuminates the complexity of wildlife disease management.

Key Facts

Bovine tuberculosis (bTB) costs the UK around 100 million pounds annually; over 30,000 cattle were slaughtered to control it in 2022.
Badgers are a wildlife reservoir for bTB; the extent of their role in cattle infection remains scientifically contested.
The UK government culling policy has killed over 200,000 badgers since 2013; effectiveness evidence is disputed.
Shooting is the primary culling method; injured animals may escape and die slowly from wounds.
Vaccination of badgers with BCG reduces new bTB infections by approximately 74% in vaccinated animals.
Biosecurity measures on farms — preventing cattle-badger contact — can reduce transmission risk significantly.
The badger vaccine does not cure existing infections; it reduces future transmission without eliminating the reservoir.

Welfare Considerations

Badger culling for bTB control creates welfare harms at scale: hundreds of thousands of animals shot over large areas, with a proportion wounded and dying slowly. The scientific evidence supporting culling effectiveness is contested — the landmark Randomised Badger Culling Trial found that culling in contained areas reduced cattle bTB incidence, but also increased incidence in surrounding areas through perturbation effects. Vaccination offers a welfare-superior alternative: BCG vaccination significantly reduces new infections without the killing of potentially uninfected animals or the perturbation effects that spread disease. The welfare-positive policy position combines badger vaccination, improved cattle biosecurity, and more accurate cattle testing — a comprehensive approach that addresses bTB without the welfare cost of mass culling.
