I declare an interest as I am a cattle keeper; indeed, over the past five years I have had a herd that went down with TB. My comments will not be made on a personal or anecdotal basis, and certainly not on an emotional basis, but rather they shall be based on sound science.
It is interesting to reflect a little on the history of this issue. Until 1950, bovine tuberculosis was endemic in British cattle herds. As a zoonotic disease that can be transmitted from animals to humans, that was obviously a danger, so the Government decided to eradicate it. They were spectacularly successful, and by about 1960 there were few instances of bovine TB in cattle herds. That situation was maintained for about 20 years, but in 1971 a dead badger was found to be infected with bovine tuberculosis on a farm where cattle had gone down with the disease, and from then on it became ever more apparent that badgers were involved in the spread of the disease.
The Badger Trust website states that bovine TB
“may also be caught through contamination of feeding and watering sites and from infected wildlife, including badgers”.
That is what led to the trials by Lord Krebs, which I commend as a piece of scientific work, but only in as far as they went.
When that work was concluded, Sir David King, chief scientific adviser at the time, was asked to prepare a report. I do not have time to go through that report, but I recommend it to hon. Members. It is an extraordinarily balanced and insightful piece of work that needs looking at. Sir David King came to the conclusion that by building on trials by Lord Krebs, and by identifying their weaknesses, pilot schemes could be introduced that would lead to the minimisation of bovine TB in this country.
Sadly, in 2007 the right hon. Member for Leeds Central (Hilary Benn) rejected that report and we have had five wasted years. Although the Government introduced extra measures for farmers, nothing was done to address the wildlife reservoir, and five years on, we must deal with a much more difficult situation than in 2007. Sir David King’s report is a wonderful piece of work, and I commend it to Members.
Let me say a little about vaccination. The hon. Member for Brighton, Pavilion (Caroline Lucas) said that the most appropriate vaccine to use at the moment is the BCG vaccine. That is true because it is the only vaccine. It was developed in about 1910, first used in 1921, and whenever and however it is tested, its effectiveness ranges from about 60% to 80%. In some circumstances, it is not effective at all, and it was withdrawn from human use in this country in 2005. We are told that a wonderful new vaccine is on the horizon—new technology—but no, we will still be using the vaccine that I was given 50 years ago, as, I am sure, were many other hon. Members.
