Bovine Tuberculosis Control and Badger Culling

Neil Hudson Excerpts

Monday 13th October 2025 Westminster Hall

[Dr Neil Hudson (Epping Forest) (Con)]

It is a great pleasure to serve under your chairmanship, Mr Stuart. I first declare my professional and personal interest as a veterinary surgeon and a fellow of the Royal College of Veterinary Surgeons. I thank the hon. Member for North Ayrshire and Arran (Irene Campbell) for her thoughtful opening of this debate on behalf of the Petitions Committee. I have a huge amount of respect and admiration for her as a passionate advocate of, and champion for, animal welfare. I also thank the 102,458 signatories to the petition, including the 143 from my constituency of Epping Forest.

We have heard many contributions from across the House today about many of the tools in the toolbox for tackling bovine tuberculosis. We have heard from the hon. Members for Glastonbury and Somerton (Sarah Dyke), for Stourbridge (Cat Eccles), for York Central (Rachael Maskell), for Camborne and Redruth (Perran Moon), for St Ives (Andrew George), for Worcester (Tom Collins) and for Scarborough and Whitby (Alison Hume). Some of the key elements that came out in those contributions were the mental health impacts of this disease—I will touch on that later in my speech—and the different tools that are currently available to us, or are being developed, to tackle the disease. No particular tool is perfect, but we need to be looking at a combination of tools in the toolbox.

I think we can all agree that, as we have heard, bovine tuberculosis has devastating consequences, and at present there is no single method that, in isolation, is perfect for combating it. During this debate it has been encouraging to hear colleagues from across the House reiterate the fundamental key aim, which is that we all want to eradicate bovine TB. That aim should unite all stakeholders, including farmers, animal welfare groups, scientists and veterinarians. Loud and clear in this debate is the importance of animal welfare—the welfare of the cattle and also the badgers.

As we have heard, there are various numbers for the cattle that are slaughtered, but many thousands are slaughtered each year in the UK as part of the effort to eradicate this awful disease. Equally, there are different levels for the cost, but it is estimated that the cost to the UK taxpayer is £150 million per year, with additional costs falling on the cattle sector itself.

Bovine TB takes a terrible toll on farmers, leading to the loss of highly prized animals and, in the worst cases, entire valued herds. It has devastating impacts on farming businesses up and down the land, and as we have heard across the Chamber it has significant effects on the mental health of everyone involved.

In the last Session, I was a member of the EFRA Committee and triggered an inquiry and report on rural mental health. Some of the most powerful evidence we took was from the veterinary and farming sectors about the mental health impacts on farmers and other workers, including vets, from bovine TB. The stress and anxiety around the testing of a herd, the trauma and consequences of having positive reactors in a herd, and the implications and outcomes of infection in a herd are devastating. We cannot overstate the loss of animal life and the human emotional impact that result from infectious disease outbreaks in farming.

My experiences as a veterinary surgeon in the foot and mouth crisis in 2001 are a huge part of my journey to this place as a Member of Parliament. I saw sights then that I never want to see again in my lifetime.

Bovine TB is a very complicated situation, with complex epidemiology that, I am afraid, still very much implicates wildlife reservoirs such as badgers in the spread of the disease. The disease can be spread between cattle, from cattle to people—it is important to realise it is a zoonotic disease—and between cattle and badgers. The latter transmission can be from cow to badger and vice versa. The review for the Government by Godfray in 2018, which was updated in August this year, clearly states that there is transmission to and from badgers and cattle, and that the presence of infected badgers poses a threat to cattle herds. The Godfray review also emphasised the impact that the disease has on the welfare and wellbeing of farmers and their families—a discussion we have heard today.

In October 2023, NFU Cymru released the results of a survey it had conducted. Of the 507 farmers who had completed the survey, 85% said bovine TB had negatively impacted their mental health or the mental health of someone in their family. Over 93% said they were extremely concerned or very concerned about bovine TB. The 2025 update to the Godfray review also took time to stress the significant research undertaken on bovine TB and its mental health impacts, and recommended that

“those dealing directly with farmers in a regulatory or advisory capacity, received basic mental health first aid and suicide awareness training.”

I strongly support that recommendation and very much urge the Government to work to implement it as soon as possible, in addition to other, similar recommendations that we made in our EFRA report on rural mental health.

As we have heard today, there are significant challenges with the testing for and diagnosis of bovine tuberculosis. Testing is so important, and more work is needed on the optimal tests for the disease, taking into consideration both sensitivity and specificity. There is a debate about the strengths and weaknesses of the currently used single intradermal comparative cervical tuberculin—SICCT—test. Godfray talks about the move to the more sensitive single intradermal cervical tuberculin—SICT—test. Indeed, the British Veterinary Association also talks about the potential roll-out of the interferon-gamma test as a supplement to the SICCT. Those diagnostic tests are just one tool in our toolbox to control and eradicate bovine TB.

During the tenure of the previous Conservative Government, in a major scientific breakthrough, the Animal and Plant Health Agency developed a companion candidate test—the so-called DIVA test—to detect infections among vaccinated animals, and differentiate a vaccinated animal from a naturally infected one, and the hon. Member for St Ives spoke about that test. That major breakthrough brought us closer to being able to strategically vaccinate cattle in England against this insidious disease but, as we have heard, we are not quite there yet with that test. I urge the Government and the Minister that this must remain a huge and urgent priority, and I hope she will update us on the progress of the field trials and roll-out of that vital tool.

The previous Government drove forward an ambitious strategy to eradicate bovine TB in England by 2038. That strategy set out a range of evidence-led interventions to tackle the disease in both cattle and wildlife, including by strengthening cattle testing and movement controls; introducing new help for herd owners to improve biosecurity measures on farms and manage down the risk of bringing the disease into their herds; and supporting the deployment of badger vaccination. I cannot stress enough how important biosecurity measures are in the control of this disease, just as they are for many other infectious diseases, as we have heard in the debate, and that too was emphasised by the Godfray review and by the British Veterinary Association.

I cannot pass the word “biosecurity” without stressing that this issue is another clear demonstration of how crucial it is that our biosecurity is firing on all cylinders, and that the APHA is fully equipped at the forefront of the UK’s fight against animal disease outbreaks and their potentially devastating consequences. After pressing the Government no fewer than 17 times in this Parliament to fully fund the redevelopment of APHA’s headquarters in Weybridge, I am relieved that their national security strategy committed £1 billion to do so. I welcome that major commitment from the Government, which continues the work started by the previous Conservative Government.

However, that £1 billion, combined with the £1.2 billion provided by the previous Conservative Government in 2020, still leaves us with a shortfall of £400 million from the £2.8 billion that the National Audit Office outlined is required. The current plans mean that the redevelopment will not be complete until 2034, with interim laboratories not in place until 2027-28. The 2025 update of the Godfray review explicitly concludes that a “lack of investment” in the APHA, and in DEFRA more widely, is still limiting our control of bovine TB. That needs to be addressed with urgency.

Our wider short-term biosecurity is equally vulnerable, as outlined this year in the alarming findings of two new reports by the EFRA Committee. The “Biosecurity at the border: Britain’s illegal meat crisis” report stated that seizures of illegal meat imports have soared from 164 tonnes in 2023 to 235 tonnes in 2024. If we think about the amount that we are not detecting, it is a frightening statistic. Meat being handled in poor sanitary conditions is already creeping through into our food chain. As with bovine TB, the EFRA Committee’s reports note that a key part of this problem is a lack of strategic resourcing by DEFRA, such as DEFRA currently funding only 20% of the Dover port authority’s operational coverage, which is only made worse by poor data collection and sharing at present.

All of that is against the worrying backdrop of the worldwide biosecurity context, with foot and mouth disease outbreaks this year in Germany, Hungary and Slovakia; African swine fever spreading across the European continent; and avian influenza, bluetongue virus and, as we are discussing today, bovine TB very much with us in the United Kingdom. Those are critical and grave threats, and we cannot afford any complacency by any Government of any political colour, so I urge the Government to carry on really focusing on biosecurity. I shudder to think of the consequences if this situation is not improved as a matter of urgency. I would be grateful if the Minister could outline what the Government are doing about the biosecurity situation in her response.

We have heard about vaccination of cattle today, and another vital tool in the toolbox is vaccination of cattle against TB. At present, cattle are starting to be vaccinated with the cattle BCG vaccine, which is based on the human BCG vaccine—a weakened strain, which does not cause disease. However, the BCG does not give 100% protection against the disease. On its own, that particular tool is not the silver bullet; it needs to be used in combination. As Godfray states, the development of a successful BCG/DIVA product is still not there and still not guaranteed, so we need to make sure that it is scaled up and rolled out at pace. Therefore, cattle vaccination should not be considered as the end result, but as complimentary to a comprehensive testing and surveillance programme.

It is also important to highlight efforts to vaccinate the wild badger population. Practically that is, as one can imagine, a much more difficult job than vaccinating cattle. As Godfray states, the vaccination of badgers can help, but it may take over a decade based on current approaches. The Government launched a national badger population survey in February, and further surveying is scheduled to resume later this year to estimate badger abundance and population recovery. I would be grateful if the Minister could clarify when the results of those surveys will be published.

The last Government supported efforts to control the spread of the disease, and a new version of the ibTB mapping tool was launched, which is enabling farmers to access information on TB-free farms and facilitate safer trading.

Unfortunately, this year’s update of the original Godfray review has concluded that

“there is only a small chance of meeting the target without a step change in the urgency with which the issue is treated and the resources devoted to eradication.”

Sadly, we again are being warned that a lack of resourcing when it comes to animal welfare is an obstacle to doing what we need to do. That must change.

Moving forward, strategies to eradicate the disease must focus on vaccination. However, until that can be done at the speed and scale required, other control methods are still required. That includes the use of culling in the wildlife reservoir population of badgers, which has been shown to be an effective method of controlling the spread of the disease. We have had debate about that today.

Part of ensuring that culling is undertaken as necessary is ensuring that, behind alternative tools such as vaccination, we have the body of evidence necessary to give us the clearest possible picture of their effectiveness, strengths and limitations. The National Farmers Union and the British Veterinary Association have emphasised the need for this evidence, particularly when it comes to the use of vaccination and its impact on herd incidence. That can not only have benefits in terms of how vaccination could be used as a potential exit strategy or to stop disease spreading into new areas, but could give confidence to farmers that alternatives to badger culling can be effective and motivate those with livestock at risk of bovine TB to take part in Government measures, particularly in the light of the fact that, as we have discussed today, the Government have announced that they intend to end the badger cull by the end of this Parliament.

When it comes to information collection and sharing, both the Godfray review and the National Audit Office have stressed the disappointing progress made on the livestock information transformation programme, which drives livestock traceability. The Godfray review’s updated publication this year found that speeding up progress on that programme is essential to eradicating bovine TB by 2038. The National Farmers Union notes that this is a huge opportunity for the industry to unlock a wealth of additional information; I urge the Government to look at how the benefits of that can be unlocked as soon as possible in the essential task of data gathering.

The Labour Government’s ending of the badger cull seems a high-stakes gamble and does not appear to follow all the science or the evidence. For example, the study by Downs et al. published in 2019 found that after four years of culling, reductions in TB incidence rates in cattle herds were 66% in Gloucestershire and 37% in Somerset, relative to comparison areas. In 2024, Birch et al. found that, in a study from 2013 to 2020, the herd incidence rate of TB decreased by 56% up to the fourth year of badger control policy interventions.

[Andrew George]

I am repeating myself, but the hon. Gentleman must understand that those research papers were questioned heavily as, during the period over which the statistics were gathered, they were not based on the same baseline nor on the same system as cattle testing at that time. Therefore, they did not compare like with like. That was very heavily questioned at the time, and it was never satisfactorily resolved.

--- Later in debate ---

[Dr Hudson]

I respectfully disagree with the hon. Gentleman. The Birch et al. study of 2024 looks at that issue in depth. Indeed, if we look at some of those scientific studies criticising the badger cull, the Government’s DEFRA chief scientific adviser and the chief veterinary officer queried the statistical methodology of those. We can have a long debate about the methodology of those papers, but Godfray himself, and the expert panel reconvened by the new Government, looked at a lot of the evidence, which shows that there is still a role in some way for badger control. I hear what the hon. Gentleman says, but I will carry on.

The previous Government were clear that they did not want or intend to continue badger control indefinitely. No one wants to keep going with it forever. However, until all the tools in the toolbox—we have heard today about many of those tools, and they are not all there yet—are fully developed and up to speed, His Majesty’s Opposition believe that, sadly, badger control needs to be kept in that toolbox. I know that will disappoint many stakeholders watching this debate and many people in the Public Gallery, but we must try to be dispassionate and follow the science. One of the key take-homes from the Godfray review was that the polarisation of the role of the wildlife reservoir and the badger in this debate, and the fact that it has split people into one view or the other, has made it very difficult for everyone to analyse the exact risk and the best control mechanism.

The British Veterinary Association states that when badger culling is deployed, it

“should be deployed in a targeted, effective and humane manner only where cull design is based on the best available evidence and mitigates against the ‘perturbation effect’”,

which we have heard a little about today.

The National Farmers Union states that to tackle the disease effectively and combat transmission through all routes we must retain access to all tools, and their implementation must be driven by science and evidence.

More widely, on rural issues, this Labour Government have already shown us that sometimes they do not follow the evidence or data in policy decisions for farming and rural communities. Just look at their retrograde approach to taxation on farms, ignoring the devastation that the family farm tax will have on the very livelihood and survival of rural businesses, and choosing to add to the pressures on farmers’ pockets and wellbeing, rather than providing them with the support they need. I too urge the Government to reverse the policy as a matter of urgency—something we have heard from across the House—to give clarity to farmers and to abolish the family farm tax.

I hope the Government do not make another error by losing the progress made since 2014 in the control of bovine TB. If we take a quick decision without looking at all the science and the evidence, we might take backwards steps that will have significant impacts on our rural communities. At present, we need all the tools to remain in the bovine TB control toolbox: biosecurity measures, better diagnostic testing, cattle vaccination, badger vaccination, roll-out of the DIVA test and targeted control of the wildlife reservoir.

To conclude, I reiterate that His Majesty’s official Opposition believe that targeted, humane and evidence-based badger control should remain a measure—not forever, but so long as the evidence says that it needs to stay in place. It is an available part of the toolbox, alongside others, to control the spread of the devastating disease that is bovine TB. The previous Government set out their ambition to eradicate the disease by 2038, and it is important to highlight that the current Government have not changed that target year. We should follow the science, the evidence and the data, for the sake of our cattle sector, our rural communities and, indeed, rural mental health.
