Bovine Tuberculosis

Lord Winston Excerpts

Tuesday 23rd October 2012 Lords Chamber

[Lord De Mauley]

I am grateful to my noble friend because this is an important subject into which considerable work is going on. The evidence that he has referred to will of course be taken into account. Progress on the development of an effective oral badger vaccine relies, of course, on scientific breakthroughs in this field, and it is uncertain in outcome and timing. Compared to an injectable vaccine, an oral vaccine is technically more difficult to formulate, as my noble friend alluded to, and it requires bait, which encourages the uptake of the vaccine by badgers and minimises the potential of other species to eat it. Developing an oral vaccine against TB in badgers is proving more difficult than originally hoped, which means that I cannot say with certainty when one might be available for use in the field.

[Lord Winston]

My Lords, will the Minister inform us whether the Government intend to cull the seven or eight other common species which also affect tuberculosis and spread it among cattle?

[Lord De Mauley]

That is an interesting question. Although bovine TB is present in other wildlife, such as deer, badgers are the main species responsible for transmitting the disease to cattle because of their specific ecology. Evidence from the RBCT demonstrates conclusively that badgers contribute significantly to bovine TB in cattle. While deer in Britain are generally considered to be a sentinel or spillover host of infection in cattle, rather than a source of the disease in cattle, current evidence suggests that TB infection from deer is not a significant disease risk to cattle.
