I congratulate the hon. Member for High Peak (Ruth George) on securing this debate and, as several hon. Members have said, on the sensitive way she approached a difficult and contentious issue, particularly in her recognition of the trauma this issue causes farmers.
Bovine TB is one of our most difficult animal health challenges. It is a slow-moving, insidious disease. It is difficult to detect. None of the diagnostic tests are perfect. I will come on to that later. It can exist in the environment for several months. There is a reservoir of the disease in the wildlife population, hosted in badgers. No vaccination is perfect. The best vaccine we have is the BCG vaccine, which typically provides protection of around 70%.
As the hon. Lady said, bovine TB also imposes a huge pressure on the wellbeing of our cattle farmers and their families. As many hon. Members have said, including my hon. Friend the Member for Congleton (Fiona Bruce), it is a tragedy when farmers have a TB breakdown. Some farmers lose show-winning cattle. For many, their herd of cattle is their pride and joy, and it is utterly soul-destroying to see those cattle lost.
No single measure that will achieve eradication by our target of 2038. That is why our 25-year strategy, launched by my right hon. Friend the Member for
North Shropshire (Mr Paterson) in 2013, sets out a wide range of interventions. Cattle testing is the cornerstone of our current programme. Several hon. Members, including the hon. Member for Edinburgh North and Leith (Deidre Brock), suggested that we are focusing on badgers at the expense of other interventions. That is simply not true. We have a wide range of testing regimes.
There are regular surveillance tests, every four years in the low-risk area, every year in the high-risk area and every six months in hotspots. There are pre-movement tests. Recently, we introduced compulsory post-movement tests for cattle moving between holdings. There are trace tests on cattle that have recently been added to a herd. We have tests on a herd following a sale of cattle to another herd, where that leads to a TB breakdown. We have radial testing in some areas and contiguous testing in others, where there are implications from a neighbour’s farm with a breakdown. Where there are inconclusive reactors, we have re-tests. Recently, we dramatically increased the use of the far more sensitive interferon gamma test, to ensure that we detect the presence of the disease and root it out faster from our herds.
It is not correct to say that our policy is built solely on the contentious badger cull policy. The cornerstone of our fight against TB is and always has been a very thorough testing regime, to remove the disease from cattle. All the demands we place on farmers through testing, despite the trauma concerned and the dangers they pose, are crucial to our fight against the disease. We must continue to be vigilant on this front. That was one of the recommendations from the review conducted by Sir Charles Godfray.
Seven years into our 25-year strategy to eradicate TB, we feel that it is a good time to reflect on the strategy and think about other elements we might want to evolve. That is why the former Secretary of State asked Sir Charles Godfray to conduct a review around the five-year point of the strategy. That was published a little under a year ago. Several hon. Members have asked why the response has been delayed and when to expect it. All good things are worth waiting for. I envisage the response being published soon. I hope it will not be interrupted by an election purdah.
The response to the Godfray review is an opportunity for us to take stock and review the current strategy, seven years in. The shadow Minister offered to work with me on this. When we publish our response to the Godfray review, I will invite him and his team to meet me in the Department for Environment, Food and Rural Affairs to go through what we are proposing. The tone of this debate has been slightly different to previous debates on the matter. While we will never entirely agree, I detect a sense that both sides can make a step towards one another and achieve a consensus on certain issues. I am keen to try to achieve that. This is a long- term fight—it is a 25-year strategy—so it would be helpful to have cross-party understanding and consensus on elements of it.
This debate relates to Derbyshire. As the hon. Member for High Peak knows, we took a difficult decision to pause a proposed cull in the south of Derbyshire. I understand that has caused great frustration to farmers. We did that to ensure that we can assess how we can have co-existence of badger vaccination and culling in parts of the edge area. That is why we chose to pause it for this year.
Badger culling is a controversial policy. We have powerful scientific evidence to show that the cull is working, despite passionate attempts by some to suggest otherwise. TB was first identified in the badger population as long ago as 1971. A series of trials in the 1970s demonstrated that a badger cull could lead to significant reductions in the incidence of the disease. That was borne out further by the randomised badger culling trial in the early 2000s.
Crucially, a recent independent peer-reviewed epidemiological study, published by Downs and others in the internationally-renowned scientific journal Scientific Reports, showed that licensed badger culling is leading to a significant reduction in the incidence of the disease in cattle in each of the first two cull areas. The study showed that there was a 66% reduction in TB incidence rates in Gloucestershire and a 37% reduction in the Somerset cull area, over the four years of intensive badger culling, relative to similar comparison areas. No significant changes have yet been observed in the third area in Dorset, but that is after just two years of culling. Furthermore, there was no evidence of an increase in the TB herd incidence rates in cattle located around the buffer area. One of the key findings of the report was that the so-called perturbation effect, which was a concern for some when the cull was launched, has not materialised in the culls so far.
The Government do not dismiss badger vaccination, but it is important to remember that the only vaccine we have is the BCG vaccine, which does not provide full protection. We do not have any hard, scientific evidence of how it works on a field deployment scale.
