The UK badger cull program aims to control bovine tuberculosis but kills hundreds of thousands of badgers through methods that cause significant welfare harm — with contested scientific efficacy.
Badgers killed by free shooting experience shooting that is sometimes accurate and sometimes not. Non-instantly killed animals may run wounded for distances before death. The welfare harm of free shooting is documented — an estimated quarter of badgers take more than five minutes to die. The policy is implemented on animals that have a rich social and foraging life, killing thousands in an area to prevent transmission of a disease whose exact mechanism requires ongoing research. The welfare cost is certain; the benefit is disputed.
