The scientific evidence I was referring to was the 10-year, £50-million project, which is the fundamental basis for any science relating to the cull.
The pilot culls recently completed were not supported by scientific evidence. The justification for them was that they were to
“test the assumption that controlled shooting is an effective method of badger removal, in terms of being able to remove at least 70% of the starting population in the area, over the course of a six week cull.”—[Official Report, 15 April 2013; Vol. 561, c. 70W.]
Thus, the pilots were designed to test not the science, but whether controlled shooting could achieve the crucial target of removing 70% of the badger population in the cull zone, that figure being key to achieving even a modest reduction in bovine TB.
Therefore, my first question to the Minister is, what percentage of badgers was culled in the two pilot zones? Furthermore, will he confirm the scientific advice, which indicates that if there is an underachievement of the 70% target, culling is liable to make the incidence of bovine TB worse because of the impact of perturbation? Given that the current performance in the pilot zones could only be improved by the use of cage trapping, surely the Minister will agree that the pilot has failed in its testing of the assumptions I referred to. That is the key point: the pilots were testing controlled shooting against cage trapping.
It is generally accepted that vaccination presents an effective method of disease control; yet we are often told that the cost of badger vaccination is too high. However, as has been mentioned, according to a written answer from the Minister for Policing, the cost of policing the two pilot culls was around £1.6 million. Does the Minister acknowledge that if an effective cull requires cage trapping, it is more cost-effective to tackle TB in badgers by vaccinating than by killing? I should have said earlier that a greater problem is the incidence of TB in cattle. Will the Minister acknowledge that the Government need to focus more on securing an approved cattle vaccine?
The previous Government’s response to the trials was to authorize six badger vaccine trials, which, combined with the vaccination programme in Wales, offered the opportunity to measure the effectiveness of the approach scientifically over time. The coalition, however, announced in June 2010 that
“it would be reducing the number…from six to one in view of its intention of reviewing policy on badger control, and the need to reduce spending.”
Will the Minister now agree that it was short-sighted to destroy the opportunity of making a rigorous scientific assessment of the effectiveness of vaccination in the field? Will he review that decision?
It is clear from scientific briefing that in Britain, badger behaviour is tightly defined territorially, which means that TB in badgers is to some extent contained by the animals’ social structures; so it is hard to fathom why the incidence of bovine TB has climbed so rapidly in recent years. One can only conclude that there is a need to focus on cattle movement and biosecurity to work out long-term solutions with a view to eradicating the disease.
I support my hon. Friend the Member for Derby North in calling for a review.
