The hon. Gentleman flags up an important point, which again I will come to. We agree that this is a crisis that must be dealt with now. It affects mainly English cattle farmers, and their families and their communities, and the impact cannot be overstated. If the disease continues to increase unchecked in England, it will begin to threaten herds in other nations that are currently free of the disease, such as Scotland. I want to avoid that happening.
Inexplicably, some people hypothesise that the rising incidence of bovine TB in England is attributable to badgers. I say “inexplicably” because research shows that even in remote areas of England where bovine TB is rampant, 86% of badgers are clear of the disease, with just 1.6% of the badger population considered capable of transmitting it. The role of badgers in the transmission of bovine TB to cattle is controversial.
Badger culling was conducted under a number of schemes throughout the 1970s, 1980s and 1990s. These included at different times the use of snaring, gassing, cage-trapping and shooting. Many thousands of badgers were killed prior to the introduction of the Protection of Badgers Act 1992. However, no effort was made to evaluate empirically the effectiveness of badger culls relative to reducing bovine TB incidence in cattle until the Natural Environment Research Council initiated the randomised badger culling trial in 1998.
