Written question asked by Baroness Byford (Conservative), in the House of Lords. It was answered by Lord Rooker (Labour) on Monday, 28 January 2008.

Badgers

Question: asked Her Majesty's Government:Whether there has been a comparison made of blood from badgers in areas affected by bovine tuberculosis with blood from badgers unaffected by it.

Answer: Although a number of blood-based diagnostic tests for the detection of Mycobacterium bovis (M.bovis) infection in badgers have been developed through Defra-funded research, none of these is suitable for extensive field use. Post-mortem inspection and culture of M.bovis remains the most reliable method of diagnosis. The currently available blood tests have been validated using blood from both infected and uninfected badgers. They are currently used to measure immune responses in research projects such as the development of vaccines for badgers. A difference between the two populations can be measured, but no test is 100 per cent sensitive or specific, so some false positive and false negative results will occur. It is difficult to find populations of badgers that are truly negative for bovine tuberculosis.
