As Bourne points out, the two governments are ignoring not only the science but also the history of bovine TB control. In the 1960s the disease was almost eliminated through rigorous testing of cattle herds and strict quarantine. It was when these measures were relaxed, at the behest of the industry, that the disease began to spread. Tests with a low sensitivity, which were designed to detect TB in a herd, are now misused to clear individual animals. The quarantine period has shrunk from one year to 120 days. (The safe period, Bourne says, should be two years, as the successful Australian programme shows.) The infections springing up far from the hot zone are caused not by badgers but by cattle movements.
I am actually at a loss for words. Please read the whole story on that link.
I also posted a link to another badger story a while ago.
