Bovine Tuberculosis Badger Culling: Welfare, Evidence, and Policy

The badger culling programme in Britain to control bovine tuberculosis raises profound welfare questions while epidemiological evidence for its effectiveness remains contested.

Key Facts

Bovine TB costs the UK agricultural sector over 100 million GBP annually through cattle culling and testing
Badgers are a wildlife reservoir of bTB and can transmit the disease to cattle through environmental contamination
Controlled shooting used in UK culls results in estimated non-instantaneous death rates of 5-18% across different studies
Perturbation effect from culling disrupts badger social groups and can increase disease spread in surrounding areas
Badger vaccination using BCG vaccine delivered in bait is an alternative with growing evidence of effectiveness
The Republic of Ireland pursued a different culling strategy with different epidemiological outcomes
Independent Scientific Group on Cattle TB concluded that badger culling would make no meaningful contribution to bTB control
Over 200,000 badgers have been culled in England since the programme began in 2013

Welfare Considerations

Badger culling for bTB control presents a case where welfare harm to a protected wildlife species is justified by agricultural disease control objectives, yet the epidemiological evidence for effectiveness is genuinely weak. The welfare harm of controlled shooting is not trivial: injury rates from non-instantaneous death are higher than in comparable game shooting, badger social group disruption causes chronic stress, and the perturbation effect may actually worsen disease spread. Against this welfare cost, the disease control benefit appears limited: the Independent Scientific Group reviewed the evidence and concluded that culling could not meaningfully contribute to bTB control at a national level. Vaccination offers a welfare-neutral alternative that does not cause population disruption and has growing evidence of effectiveness, making continued culling difficult to justify on either welfare or epidemiological grounds.

What You Can Do

Support badger vaccination programmes as an evidence-based alternative to culling for bTB control
Advocate for independent scientific review of culling effectiveness before any extension of culling areas
Support wildlife welfare organisations challenging culling policies through legal and advocacy channels
Learn about the evidence on badger culling to participate constructively in public policy debates
Support research into cattle vaccination as a long-term solution that eliminates the need for wildlife control
