I will not give way, because I want to get through as many other points as I can. My hon. Friend the Member for The Cotswolds (Geoffrey Clifton-Brown) and others highlighted the situation in Wales and the limitations of vaccination. He is right that it is wrong to read too many conclusions into the fall in incidences of the disease in Wales. The vaccination trials in Wales cover only about 1% of the land area. We are running our own vaccination trials in the edge area. I have met a number of wildlife groups to discuss taking that project forward to check the spread of bovine TB, so vaccination has a role in fighting this disease. Vaccination is part of the Government’s strategy.
My hon. Friend the Member for Thirsk and Malton (Miss McIntosh) mentioned the inaccuracy of the skin tests. We know that the test is only about 80% effective, but where we have a serious breakdown, we often use it in conjunction with the gamma interferon test, which has fewer false negatives but a few more false positives. We can use that where we deem it necessary. The shadow Secretary of State mentioned that the RBCT proves that culling does not work, but that is not the case. The RBCT actually proves that, at the end of the four-year cull period, there was an improvement in the number of breakdowns.
I finish by reminding hon. Members that we have the worst bovine TB situation in the developed world. We cannot let that continue if we want competitive, productive and profitable beef and dairy sectors. Other countries that have faced similar problems, as my hon. Friend the Member for Tiverton and Honiton (Neil Parish) pointed out, have demonstrated the route to long-term disease freedom. They show us that addressing the risks posed by wildlife must be part of any coherent and comprehensive approach to tackling this disease.
We now have a very clear strategy for achieving our goal of official TB-free status in England. The approach includes deploying tighter cattle measures, strengthening biosecurity, and vaccinating badgers to prevent the disease spreading from the TB high-risk area to the edge area. Unlike the Opposition, we are clear that any coherent strategy to eradicate TB must include measures to address the disease in wildlife in TB hot spots. We will continue to use all options available to us today to fight this dreadful disease, which has been out of control for 20 years. Doing nothing is no longer an option, which is why we intend to stick with this strategy.
