I don't think that was what the First Minister did at all. You will have heard me say in my earlier answer to Samuel that what he was referring to was the information that we've been given around the likely causes for increases in the low-incidence TB area. I think M. bovis is a very difficult organism to detect. There is no single test or combination of tests available that has a 100 per cent specificity, that doesn't detect any false positives and has a 100 per cent sensitivity. They can't detect all TB-infected animals. So, we use additional blood tests, for instance, such as the interferon gamma test and the IDEXX antibody test, and we use severe interpretation of the skin test so that the risk of missing infected cattle is minimised. That's the approach that we take in the low and intermediate TB areas of Wales.
