Westminster Hall is an alternative Chamber for MPs to hold debates, named after the adjoining Westminster Hall.
Each debate is chaired by an MP from the Panel of Chairs, rather than the Speaker or Deputy Speaker. A Government Minister will give the final speech, and no votes may be called on the debate topic.

The Minister of State, Department for Environment, Food and Rural Affairs (George Eustice)
I congratulate the hon. Member for Caithness, Sutherland and Easter Ross (Dr Monaghan) on securing this well-attended debate, which shows the importance of the issue.
Scotland, of course, has a very low badger population density. Scotland is also the only part of the UK to be officially TB free, but England, Wales and Northern Ireland have this big challenge. TB is a difficult disease to fight. It is a slow-growing, insidious disease. Diagnostics are difficult because the disease does not show up quickly. The only vaccine we have is the BCG vaccine and, despite decades of research, no one has come up with a more effective vaccine—the BCG vaccine is only partially effective. TB is having a huge impact on our agricultural industry and is causing huge trauma for farmers, with some 28,000 cattle a year being slaughtered.
We have put in place a comprehensive 25-year strategy to address bovine TB, and cattle control is at the heart of that strategy. Several hon. Members have said that cattle control is the answer, but I will explain what we have. We have annual testing in the high-risk area and four-yearly testing in the low-risk area. We have annual testing in the edge area and six-monthly testing in hotspots in the edge area, and we continue to consider rolling that out. We have contiguous testing in the high-risk area where there is a breakdown, and we have radial testing in the low-risk area, going out to 3 km, where we have a breakdown. We are now consulting on greater use of the gamma interferon test so that we can pick up the disease faster. We are also looking at what more can be done in other species. We are constantly trying to refine and improve our cattle movement controls, but I put it to hon. Members that for years we have been doing everything that everyone has said we should be doing.
We continue to work on vaccination. We are spending millions of pounds on trying to develop an oral vaccine for badgers because I believe that could give us an exit strategy from the cull once we have completed a reduction in the population of some areas. We are also continuing to work on cattle vaccination to develop a DIVA test. That work takes time and costs millions of pounds, but we are doing it.
In recent years we have set up an edge area vaccination programme, with a number of volunteer groups taking part. As my hon. Friend the Member for Totnes (Dr Wollaston) said, the World Health Organisation has asked everyone to stop using the vaccine we have on badgers, and we followed the Welsh Government’s lead in doing so. We will resume our testing when those stocks come back on stream.
We are doing a huge amount of work to improve biosecurity. In a few weeks’ time I will launch a cattle health certification standards—CHeCS—accreditation scheme to try to incentivise farmers to do more for biosecurity. We have grants available so that farmers can invest in water troughs that make it harder for badgers to gain access and in fencing to keep badgers away from farmyards. We are constantly trying to improve the management of slurry, and there is already a suite of measures on farmyard manure management. We are also looking at other novel things, such as genetics. Holstein UK is working on whether genetic improvement might be able to breed partial resistance into the dairy herd in particular. I have already asked our chief scientific adviser to find out whether further work could be done to enhance that.
The badger cull is just one part of our strategy but, as I have said before, there is no example anywhere in the world of a country that has eradicated TB without also addressing reservoirs of the disease in the wildlife population. A number of hon. Members have raised questions about the science. TB was first isolated in badgers as long ago as 1971. In 1974 a trial was conducted to remove badgers from a severely infected farm, with the result that there was no breakdown on that farm for five years. Between 1975 and 1978 the Ministry of Agriculture, Fisheries and Food funded extensive work that demonstrated conclusively that there is transmission and a link between badgers and cattle, and subsequent work in Ireland has reaffirmed that finding.
The Krebs review observed that between 1975 and 1979 TB incidence in the south-west fell from 1.65% to 0.4% after the cull, a 75% reduction. Subsequently, in the late ’70s and early ’80s, more extensive work was done in three exercises. One was in Thornberry, where the TB incidence fell from 5.6% in the 10 years before culling to 0.45% in the 15 years afterwards, a reduction of 90%. In Steeple Leaze there were no breakdowns for seven years after badgers were cleared. In Hartland the incidence dropped from 15% in 1984 to just 4% in 1985, a reduction of more than two thirds.
There were claims that those experiments lacked a control, which is why the randomised badger culling trial took place. Despite having the challenge of the foot and mouth crisis smack in the middle of it, the RBCT concluded that in the four years after culling there was a significant reduction in the incidence of TB. The RBCT supported what the previous trials had shown. In fact, 18 months after the culling ended in the RBCT there was a 54% reduction in the incidence of the disease, so I am afraid that hon. Members who say that we have not followed the science have themselves not read the science. The science and the veterinary advice are clear.
George Eustice
I will not give way.
This is an evidence-based policy. We cannot remove and eradicate TB without addressing the reservoir of the disease in the wildlife population. I would not sanction a cull of badgers unless it were necessary. Apart from anything else, it is incredibly expensive but I am also not the sort of person who wants to kill wildlife for fun. I would not sanction this unless it were necessary, and I believe that it is necessary.
I urge hon. Members to show some sense of perspective. I live next to Bushy Park and at this time of year, every year, a sign goes up on the gates saying, “We are afraid that the park will be closed for the next few weeks because we are having a deer cull.” Nobody bats an eyelid. They go somewhere else to have their picnic. We do not get protesters running around the park at night. Is that really so different? The level of scrutiny that we put on the culls and the requirements that we attach to licensing are incredibly thorough. We have rules on the distance that hunters have to be before they can take a shot and on precisely the type of rifles that they should have. We have rules saying that the badger must be stationary before a shot is taken. We are doing our utmost to ensure that the badger culling and shooting are done in the most effective way, more effective than for any other wildlife.
In conclusion, I believe that this is necessary. It is an evidence-based policy, which is why we continue to roll out the cull.
