Bovine Tuberculosis

Lord Krebs Excerpts

Tuesday 16th November 2010 Lords Chamber

Asked By

[Lord Krebs]

To ask Her Majesty’s Government what scientific evidence they hold which supports their proposals for control of bovine tuberculosis.

[The Parliamentary Under-Secretary of State, Department for Environment, Food and Rural Affairs (Lord Henley)]

My Lords, scientific evidence indicates that TB in cattle will not be eliminated without addressing transmission from badgers. The evidence used to estimate the impact of badger culling and vaccination on TB incidence in cattle is set out in our consultation document. For culling, much of the evidence comes from the randomised badger-culling trial, which was recommended by the noble Lord in 1997. For vaccination, it comes from laboratory and field studies.

[Lord Krebs]

I thank the Minister for that helpful Answer. As he has indicated, I declare an interest as the author of the 1997 report that led to the so-called randomised badger-culling trials, which were set up to test whether culling is an effective way of controlling TB in cattle. I ask the Minister two questions. First, does he agree with the estimate of his own officials that, based on the results of the randomised badger-culling trials, long-term intensive culling of badgers would lead to a 16 per cent reduction in the incidence of TB in cattle over nine years? Even this modest reduction, which would leave 84 per cent of the problem unaffected, would be achievable only with highly effective, large-scale, long-term culling. Otherwise, culling will make the problem worse. Secondly, does the Government’s Chief Scientific Adviser, Sir John Beddington, agree with the policy of culling?

[Lord Henley]

My Lords, on the first question, I accept what the noble Lord has to say, but ongoing monitoring since the end of those trials indicates that the positive impacts on herd breakdowns within the culled areas have lasted for a considerable number of years after the culls have ended and that those areas have seen a reduction of some 28 per cent in the incidence of TB. So there is a considerable reduction. We have never said that culling is the sole answer. We have always made it clear that we believe that other measures will need to be taken and that we need to use every tool in the toolbox. As I made clear to the noble Lord in Written Answers earlier this year, we have consulted both the Government Chief Scientific Adviser, Sir John Beddington, and our own chief scientific adviser within the department.
