Bovine Tuberculosis

Lord Dixon-Smith Excerpts

Thursday 22nd July 2010 Lords Chamber

Asked By

[Lord Dixon-Smith]

To ask Her Majesty’s Government whether the practice of skin testing for bovine tuberculosis followed by the slaughter of reactors will eliminate the disease from the national herd.

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

Tuberculin skin tests are the internationally accepted standard for detecting TB. Many countries have eradicated TB using a test and slaughter approach. In England, evidence suggests that without addressing the disease in badgers, it will be impossible to eradicate TB in cattle. The department has committed to developing affordable options for a carefully managed and science-led policy of badger control in areas with high and persistent levels of bovine TB.

[Lord Dixon-Smith]

My Lords, I thank the noble Lord for that response. There is evidence that the present testing regime correctly identifies the presence of tuberculosis within a herd, but no longer identifies all the infected animals so that after a series of tests, a residue of infection is left within the herd which can continue to spread the disease despite the removal of the identified animals. Will the noble Lord ask the Government to conduct a thorough review of the implications of this? The existing regime is not satisfactory and there are managerial consequences for biosecurity on the farm. Although this programme was very successful half a century ago, it is not working now. We are effectively burning pound notes.

[Lord Henley]

My Lords, I accept that there are occasions when using the current test—what I have described as the internationally accepted comparative test—that some cattle are missed. If we move to another test, known as the single test, there is a possibility of a greater number of what are described as false positives, which again would not be satisfactory. A further test is used, a blood test which is known as the gamma test, and we can look at it. I can give my noble friend an assurance that we will look at all three, but for the moment we think that the comparative test is the best one to use.
