New bovine TB tests needed?: Cambridge University has recommended

A NEW study performed by researchers from Cambridge University has recommended that new tests are needed to make vaccination against bovine tuberculosis (bovine TB). The report points out that in order for vaccination to be viable, the number of false positives from these tests must be significantly reduced. The scientists have said the reduction in false positives in cattle is feasible, but that a vaccination programme would be challenging. Despite an intensive, and costly, control program in the United Kingdom, bovine TB persists. Although vaccinating cattle with the human BCG vaccine offers some protection in cattle, doing so is currently illegal within the EU, due to the vaccine’s interference with the skin test used for surveillance.

The Cambridge team worked alongside researchers at the government’s Animal & Plant Health Agency (APHA), to show the importance of specificity – the proportion of uninfected animals that test negative – to making disease control strategies work. The skin test currently in use has a very high estimated specificity of over 99.97%, which means that less than three animals in 10,000 will test falsely positive. However, the test as carried out in Great Britain is thought to have at best an 80% sensitivity – a measure of how many infected animals will correctly test positive – missing around 1 in 5 bovine TB-infected cattle. It is used to determine if animals, herds and countries are officially free of bovine TB.

Vaccinated animals that test positive have to be treated as infected animals. Under European law, if an animal tests positive, it must be slaughtered. The remaining herd is put under movement restrictions and tested repeatedly using both the skin test and post-mortem examinations until it can be shown to be officially clear of infection. Researchers said the duration of movement restrictions is important due to the considerable economic burden they place on farms. Also, the cost to the UK government alone is estimated to amount to half a billion pounds over the last decade; this cost includes visits to farms by veterinarians, tests carried out and compensation for the slaughter of infected animals.

For vaccination to be economically viable and acceptable within the EU, the benefits of vaccination must be great enough to outweigh any increase in testing. A new generation of diagnostic tests, known as ‘Differentiate Vaccinated from Infected Animals’ (DIVA) tests, has opened up the opportunity for the use of BCG within current control programmes. The EU has recently outlined the requirements for changes in legislation to allow cattle vaccination and a recent report from its European Food Safety Authority (EFSA) emphasized the importance of demonstrating that BCG vaccine works, and that DIVA tests can be shown to perform in large-scale field trials.

However, a key factor overlooked in the EU report was that the currently viable DIVA tests have a lower specificity than tuberculin testing; this could lead to vaccinated herds being unable to escape restrictions once a single test-positive animal has been detected, as the more times the herd is tested, the more likely the test is to record a false positive. In their study, the researchers from Cambridge and APHA used herd level models to show that the level of infection can be reduced in vaccinated herds even when DIVA sensitivity is lower than tuberculin skin testing.

However, in order to see this benefit of vaccination over 99.85% of uninfected animals will need to test negative in the DIVA test. This improved accuracy will be necessary to avoid increasing the duration of breakdowns and the number of animals condemned. Using data from previous tests on cattle, the researchers said this level of ‘specificity’ is achievable, though they said there will be challenges associated with improving accuracy. The researchers said, “Currently, there is no gold standard test to diagnose TB in cattle. Cattle that test positive are slaughtered immediately and therefore have rarely developed any physical signs – in fact, only around a half of animals examined post-mortem show physical signs of infection even if they are, indeed, infected.”

Dr Andrew Conlan from the Department of Veterinary Medicine at the University of Cambridge explained “In order for vaccination to be viable, we will need a DIVA test that has extremely high specificity. If the specificity is not good enough, the test will find false positives, leading to restrictions being put in place and a significant financial burden for the farmer. “But validating a test that has a very high specificity will in itself be an enormous challenge. We would potentially need to vaccinate, test and kill a large number of animals in order to be confident the test is accurate. This would be very expensive.”

Badger Trust launches manifesto ahead of 2026 Senedd elections

THE BADGER TRUST has published a new Cymru Badger Manifesto calling on candidates standing in the 2026 Senedd elections to commit to a science-led approach to bovine tuberculosis (bTB) and to maintain Wales’ current policy of not culling badgers.

The manifesto, released on Wednesday (Dec 10) as part of the charity’s Badgers Belong Here / Mae Moch Daear yn Perthyn Yma campaign, sets out the organisation’s position on badger protection, wildlife crime and bTB control, and urges politicians to reject calls for the reintroduction of culling in Wales.

Badger Trust argues that political decisions taken during the next Senedd term will be critical to the future of badgers, which it describes as culturally and ecologically significant to Wales. The charity says badgers have been present in Wales for more than 250,000 years and remain part of Welsh folklore, place names and rural identity.

Five key commitments

The manifesto outlines five commitments the charity is asking Senedd candidates to support, including defending what it describes as science-led policy on bTB, challenging misinformation in public debate, strengthening enforcement against wildlife crime, recognising badgers as part of Welsh heritage, and supporting local volunteer badger groups.

According to Badger Trust, 140 incidents of badger-related wildlife crime have been recorded in Wales since 2020, which it says highlights the need for improved reporting and enforcement.

The charity also points to the work of six active badger groups across Wales, which it says assist with rescuing injured animals, monitoring setts, recording road casualties and supporting local authorities.

bTB policy in Wales and England

Wales has not carried out widespread badger culling as part of its bTB control strategy, instead focusing on cattle testing, biosecurity measures and herd management.

Badger Trust claims that new herd incidents of bTB in Wales fell by more than 40% between 2010 and 2024, which it attributes to cattle-based controls rather than wildlife intervention.

The charity contrasts this with England, where it says almost 250,000 badgers have been culled over the past decade as part of bTB control programmes. It argues that bTB rates in England remain higher than in Wales and that the evidence does not show culling alone to be responsible for reductions in disease.

Disputed claims over culling

The manifesto challenges the frequently cited claim that badger culling in England led to a 56% reduction in bTB in cattle. Badger Trust says this figure has been misinterpreted and that studies cited in support of culling also involved additional measures such as enhanced cattle testing and biosecurity.

The charity points to statements from researchers and official correspondence which, it says, indicate that reductions in bTB cannot be attributed solely to culling.

Supporters of culling, including some farming groups, continue to argue that wildlife control should remain an option as part of a wider disease management strategy, particularly in areas with persistent infection. The Welsh Government has previously said it keeps its bTB policy under review in line with emerging evidence.

Call to candidates

Nigel Palmer, CEO of Badger Trust, said Wales demonstrated that bTB could be tackled without killing wildlife.

He said: “Wales is a world-leading example of how to address bovine TB through evidence-based policy. The progress made here shows that culling is not necessary, and we urge Senedd candidates to stand by the science.”

The manifesto is available in both Welsh and English and will be circulated to political parties and candidates ahead of the 2026 election.

Basic Payment Scheme 2025 balance paid to 95% of Welsh farmers

Final year of BPS as transition to Sustainable Farming Scheme begins

The WELSH Government says more than ninety-five per cent of farm businesses have now received their full or balance payment under the final year of the Basic Payment Scheme (BPS), ahead of the introduction of the new Sustainable Farming Scheme (SFS) in 2026.

Announcing the update on Friday (Dec 12), Deputy First Minister and Cabinet Secretary for Climate Change and Rural Affairs, Huw Irranca-Davies, confirmed that over 15,400 Welsh farm businesses have been paid £68.7m. This comes on top of the £160m issued in BPS advance payments since 14 October.

Final round of BPS payments

The Basic Payment Scheme, which has been the backbone of farm support in Wales for a decade, provides direct income support to help farmers plan and manage their businesses. BPS 2025 marks the last year in which full BPS payments will be made before the scheme begins to be phased out.

The Cabinet Secretary said officials would “continue to process the outstanding BPS 2025 claims as soon as possible,” adding that all but the most complex cases should be completed by 30 June 2026.

Payments issued today represent the main balance due to farmers following earlier advances, giving many businesses the cash flow they need during the quieter winter period—traditionally a challenging time in the agricultural calendar.

Shift to Sustainable Farming Scheme in 2026

From 1 January 2026, the Welsh Government will begin rolling out the Sustainable Farming Scheme, a major reform to how agricultural support is delivered. The SFS will reward farmers for environmental outcomes such as habitat management, carbon reduction and biodiversity improvements, alongside continued food production.

The government has argued that the new scheme is essential to meeting Wales’ climate and nature targets while ensuring long-term resilience in the sector. However, the transition has been closely watched by farming unions, who have raised concerns about the administrative burden, income stability, and the speed at which BPS is being phased out.

Mr Irranca-Davies reaffirmed the government’s stance, saying: “This government is steadfastly committed to supporting Welsh farmers to sustainably produce quality food. This is demonstrated today in our payment of the BPS 2025 balance payments and will continue throughout the transition period.”

Sector reaction

Farming unions are expected to scrutinise the detail of today’s announcement, particularly around remaining unpaid cases. Last year, late payments led to frustration in parts of the sector, with unions calling for greater certainty as the industry faces rising input costs, supply chain pressures and continued market volatility.

The move to the SFS remains one of the most significant agricultural policy changes in Wales since devolution. Ministers insist the shift is designed to support both food production and environmental stewardship, while critics warn the transition must not undermine farm viability—especially for family-run livestock farms that dominate rural areas such as Pembrokeshire, Ceredigion and Carmarthenshire.

What happens next

Farmers still awaiting their BPS 2025 balance will continue to be processed “as soon as possible”, the Welsh Government said. Officials will also publish updated guidance on the Sustainable Farming Scheme ahead of its launch.

The coming year will therefore become a pivotal moment for Welsh agriculture, as the long-standing BPS framework—which provided over £200m annually to Welsh farmers—makes way for a new results-based model that will shape the industry for decades to come.
