The hon. Gentleman makes a valid point and I will come to it shortly.
In 2013, more than 6 million bTB skin tests were performed in England in an attempt to identify the disease, leading to the slaughter of more than 26,000 cattle. These tests are only 20% to 50% effective. One quarter of herds in the south-west and west midlands regions of England have been placed under movement restrictions at some point, and in the last decade the rising incidence of the disease has cost the UK taxpayer more than £500 million. Today, 20% of all new herd breakdowns are detected in the slaughterhouse, such is the ineffectiveness of current testing programmes.
