I am grateful to my hon. Friend for her question, in which she raises one of the most pertinent points: there is no single solution. Removing wildlife alone is not the solution. There has to be parallel, and equally rigorous, work on cattle. There must be a mixture of both measures. That is the lesson to be learned from the countries I have recently visited, as I was just about to go on to explain.
In recent months, I have been to Australia, New Zealand and the Republic of Ireland, and when I was in Opposition I went to the United States of America. All those countries have made great progress in dealing with very similar problems to ours by dealing with the wildlife reservoir and bearing down on the disease in cattle.
In Australia, a national eradication programme spanning almost three decades enabled official freedom from bovine TB—an infection rate of less than 0.2% under OIE rules—be achieved in 1997. Its comprehensive package of measures to tackle the disease in domestic cattle and wildlife included rigorous culling of feral water buffalo. Australia’s achievement is even more impressive when one considers the difficulty of the terrain and the size of the area over which such an extensive programme of testing and culling took place.
After my visit to Australia, I went to New Zealand. Its comprehensive and successful package of measures to eradicate the disease has focused on the primary wildlife reservoir of brush-tailed possums. As a result of its efforts, New Zealand is on the verge of achieving BTB-free status. The number of infected cattle and deer herds has reduced from more than 1,700 in the mid-1990s to just 66 in 2012.
The Republic of Ireland, too, has a comprehensive eradication programme, which includes the targeted culling of badgers in areas where the disease is attributed to wildlife. From massive problems in the 1960s—160,000 cattle were slaughtered in 1962 alone—the Irish authorities have turned things around to the extent that the number of reactor cattle has reduced to just 18,000 in 2012, a fall of 10,000 in the last 10 years. On their own figures, herd incidence has fallen to just 4.26%—a statistic we would dearly love to have here.
