I declare an interest as a member of the National Farmers Union, the Farmers Union of Wales, and the Country Land and Business Association. Indeed, I still own and keep some cattle. A couple of weeks ago we had a clear TB test, but we have only seven cattle on the farm, now. We used to have well over 200, but because of the difficulty of managing them, as a result of TB, it was decided to get rid of them. We are not the only farm that has taken that decision.
Bovine TB is a very dangerous disease, for cattle and for badgers. It is a zoonotic disease, and it affects humans as well as animals. That, indeed, is why in the 1950s and 1960s there was a great move to rid the country’s cattle herd of bovine TB. Many human beings were infected by drinking raw milk. If the Government did not believe that TB was still a matter of public health, they would presumably wash their hands of it and let farmers get on with things on their own. However, it is still a very serious disease not only for animals but for human beings.
In about 1971 the infection link between badgers and cattle was established and in 2007 the report of the randomised badger culling trials—I am not quite sure whether Professor Krebs or Professor Bourne was in charge at the time—said that between 40% and 50% of cattle infections resulted from transmission by badgers. That was established in an entirely independent assessment. Little mention has been made of DEFRA’s 25-year TB eradication strategy and what it entails—[Interruption.]—I am sorry if I have not paid attention. It is being rolled out at the moment and includes more frequent—yearly—testing in areas where there is bovine TB, more movement restrictions, increased biosecurity, and vaccination at the edge of areas of spread of the disease.
The disease is out of control, spreading northward and eastward at an increasing rate. We must try to hold it back, to protect areas that are still free of bovine TB. The Government have decided to do that through a vaccination strategy, because they realise that culling in an edge area could lead to perturbation and increase the
incidence of the disease. However, in areas where it is well established, and where other ways of controlling it have proved ineffective, they have introduced a pilot culling scheme. That approach is based on the randomised badger culling trials, which said that if culling were to be effective it would have to be on a bigger area with, if possible, hard boundaries to prevent perturbation. Perturbation in those areas, however, will not have much effect, because the disease is already well established. Probably up to 40% of the badgers are infected, so the movement of badgers will not make much difference there.
We cannot really assess the success of the culls at the moment, because we need at least four years’ information to find out. That is another thing that the randomised badger cull trial showed: results would not be obtained for about four years. However, it showed that even when those culls had stopped there were improvements in the cull areas and those surrounding them.
We must do more work on oral vaccines for badgers, vaccination for cattle, and the polymerase chain reaction that provides a possible test for infection in badgers. With that, we could trap and test badgers; the healthy ones could be vaccinated and released, and the infected ones disposed of, as vaccination could do them no good. There is a huge amount of work to be done, but I still believe that the pilot cull trials that the Government have instigated are an important part of that work in the heavily infected areas.
