Lords ChamberMy 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.
My Lords, I declare an interest as an associate member of the British Veterinary Association. Does my noble friend agree that blood testing is a good alternative or addition to skin testing and reveals more reactors? Will he consider a Defra policy of blood testing as well as skin testing in bovine TB hot spots, particularly where the badger population is considerable?
My Lords, my noble friend, I think, refers to the gamma interferon blood test, which is used alongside the tuberculin skin test in certain prescribed circumstances to improve the sensitivity of the testing regime and identify more affected animals more quickly. I shall certainly look at whether it is possible to use that test solely, but, as I said earlier, for the moment, we believe that the comparative tests that we are using are possibly the best.
