It is generally accepted that, after the initial conclusions of the randomised badger culling trials, there was a significant reduction of some 16% in the cull area in the following years. On perturbation, which other hon. Members have also raised, there was an increase in TB in a ring immediately around the trial areas as a result of perturbation, but the incidence then dropped. Overall, there was a reduction. I point the hon. Lady to evidence in other countries, such as the Republic of Ireland, which has had a cull policy since 2000 with a reduction of around 45% in the incidence of the disease, and the number of cattle having to be slaughtered has halved.
There is no magic bullet and no single policy that can change the situation dramatically. Vaccination of badgers and cattle has a role; wildlife control has a role; dealing with the reservoir of TB in wildlife has a role; and routine testing, movement controls and better biosecurity all have a role. But none of them alone is the entire solution.
