‘False positives’ must be eliminated

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.”

Cosheston gypsy traveller 60 foot shed plans refused
A CALL for a 60-foot-long shed and stables at the proposed home of a gypsy traveller family near a Pembrokeshire village has been refused by planners.
In an application to Pembrokeshire County Council, Ryan Surname Boswell & Family, through agent Hayston Developments & Planning Ltd, sought provision for an access road and replacement of temporary stables and storage containers with a multi-purpose shed and stables at Greenwells, Cosheston Bridge, Cosheston.
The application initially sought a 24.3 by 9.1 metre building, which has now been reduced to 18.3m by nine.
A supporting statement said that land to the north “is subject to a current planning application for the provision of two traveller family pitches with improvements to access and ecological enhancements with other land in our client’s ownership being un-affected”.
It added: “Mr Boswell and his family are of traveller origin and intend to make this site their family home. They own various domestic equipment, children / family articles, mowers / tools and farming equipment that require secure storage. The shed will also be used to house horses/ponies that are currently stabled in the temporary wooden stable block currently on skids on the land in question.”
It concluded: “The scale, design and use of materials (and colours) of the proposed shed is comparable to many new such sheds throughout Pembrokeshire. There will be no significant negative impacts on the level of amenity enjoyed by any neighbours or those travelling along the minor county road to Cosheston from any aspects of the proposed development.”

Local community council Cosheston had raised concerns including the “excessive” size of the proposed building, feeling “this is on the large side of what is required for a couple of ponies”.
It added: “Our concern is that the applicant intends to run his building/property maintenance business from the property. If the council grants the application, restrictions should made on the property’s use. i.e. restricted to agricultural use only.
“We have no objection to the construction of a small stable block, similar in size to the existing one on site.”
Objections were also received from two members of the public, raising concerns including the scale, environmental concerns, and a potential conflict with the ongoing application.
An officer report recommending refusal said the scheme was part-retrospective due to the prior formation of an access track within the field.
It added: “Despite amendments to the application as originally submitted by the reduction in building footprint and scale, the proposal remains a substantial and visually intrusive structure in the open countryside. An essential countryside need has not been justified nor evidence provided of an agricultural or equine enterprise warranting a building of this size or permanence.”
The application was refused on the grounds it “is not typical of a structure intended solely for the storage of paraphernalia associated with grazing land or for equine use and no information has been provided within the application to demonstrate the functional need for a building of this scale”.
It added: “The nature, siting and scale of the building would not be compatible with the capacity and rural character of the site, and together with the access track results in an unjustified and visually intrusive form of development in the open countryside, which does not represent sustainable development.”

Agrisgôp helps Welsh farming families tackle succession challenges
A PROGRAMME designed to support farming families in planning for the future is helping to break down one of agriculture’s most sensitive issues – succession.
Farm inheritance and succession planning returned to the spotlight in 2024 following UK Government reforms to inheritance tax (IHT), prompting renewed concern across the industry.
In response, Agrisgôp leader Elaine Rees Jones brought together farming families in the Welshpool area to take part in a structured programme aimed at addressing the issue head-on.
Agrisgôp, a fully funded management development initiative, encourages farmers to work collaboratively, building confidence and business skills through action learning.
Two distinct groups emerged: one made up of parents seeking to plan the future of their farms, and another of younger family members exploring how to take on responsibility and transfer knowledge from the previous generation.
A key theme identified early on was the importance of communication between generations.
Elaine said: “The meetings have offered the opportunity to gain professional and peer advice, time away from the farm to assess situations, and a safe, confidential space for discussion.
“Group members have shared concerns and apprehensions while getting to grips with the scale of the challenge, and have begun to develop action plans.
“The honesty and openness shown has been incredibly humbling.”
For many participants, the programme has provided the confidence to begin formal discussions with professional advisers.
One farming couple, currently working through the process of passing assets to their two sons, said the experience had been invaluable.
“It has made us tackle things properly. We had already started looking at succession before the Rachel Reeves budget, so this wasn’t a knee-jerk reaction.
“It’s a complicated process with no easy answers, and every farm is different. But Agrisgôp has helped us go into meetings with solicitors and accountants informed, rather than just accepting advice blindly.”
Another participant described succession planning as “mind-blowing” before joining the group, adding that expert input had highlighted the importance of early preparation.
The programme included a recent panel session in Welshpool, where professionals returned to answer questions from participants, alongside one-to-one sessions to clarify individual plans.
Specialist advice was provided on legal, financial, and land valuation matters, with a clear message emerging on the importance of having a valid will in place.
Angharad Hird, of Lanyon Bowdler Solicitors, warned that failing to make a will can have serious consequences, highlighting a case where a young farmer died unexpectedly. Under intestacy rules, his estate was divided between his wife and children in a way that may not have reflected the family’s wishes.
Financial planning was also a major focus. From April 2027, unused pension funds will be included within estates for IHT purposes, potentially attracting tax of up to 40%.
Emma Hall, a chartered financial planner, said some clients are already restructuring their finances to mitigate future liabilities, including placing assets into trusts or converting pension funds into income-generating annuities.
Land and property valuation was another key consideration. Richard Corbett, of Roger Parry & Partners, stressed that valuations must reflect current market conditions at the time of assessment, while also taking into account factors such as shared ownership or rights of way.
Accountant Sion Roberts highlighted the importance of setting emotion aside when making decisions.
“There is no one-size-fits-all solution,” he said. “Each farm is different, so it’s vital to understand your priorities and get the right advice.”
The issue of care fees and asset transfers was also raised, with warnings about the risks of deliberately reducing assets to avoid future costs.
Alongside Agrisgôp, Farming Connect’s Succession Pathway offers structured support for families navigating the process. This includes business reviews, facilitated family meetings, bespoke planning, and access to specialist legal services.
Organisers say early planning is crucial to securing both family relationships and the long-term future of farm businesses.

Call to keep holiday pod at Pembrokeshire Narberth farm
A CALL to keep a holiday pod sited on a Pembrokeshire farm, as part of a wider holiday pod farm diversification over two areas which saw the larger part supported, has been submitted to county planners.
In an application to Pembrokeshire County Council, Bill Ridge of Vaynor Farm Ltd, Bethesda, through agent Gerald Blain Associates Limited, seeks retrospective permission to keep a self-catering pod at Broomley Farm, Sodston, Narberth, works having been completed in 2022.
The application is part of a wider scheme of holiday pods diversification encompassing two farms.
Back in December, Pembrokeshire County Council’s planning committee granted delegated retrospective permission to Vaynor Farm Ltd for the siting of two self-catering holiday accommodation pods at The Cart House, Vaynor Farm, Bethesda, near Narberth as part of a farm diversification enterprise.
A supporting statement accompanying the latest application says: “Vaynor farm is a 400-acre working dairy farm with a herd of 700 milking cows. The enterprise comprises of three self-catering pods. Two of the pods are situated at the Vaynor homestead and another at the opposite end of the holding at Broomley farm.
“The first unit was sited adjacent to Vaynor farm stead some four years ago and a further two added in subsequent years. The units have enjoyed successful occupancy rates over several years offering a unique secluded tourism offer on a working dairy farm, more detail of which is outlined within the supporting business plan.”
It says the Broomley farm application is a resubmission of a previously refused scheme, adding: “It should be noted that this application was originally part of [the application] which was recommended approval at planning committee in December 2025. This element however was separated due to its location on another part of Vaynor farm deeming it not possible to be considered under the same application.”
At the December meeting, an officer report said: “A business plan has been submitted with [that] application, which explains that due to uncertainties associated with dairy farming, the applicant has sought to diversify the farm enterprise to incorporate tourism accommodation.
“The application makes the case that the proposed development represents farm diversification. It is acknowledged that the development has resulted in the provision of an alternative type of holiday accommodation for which it has been demonstrated there is a demand, contributing to the diversity and quality of accommodation available within the county and supporting an existing farm business, with consequent economic and social benefits.
“Evidence has been provided that demonstrates the extent to which the pods have provided income which has been used to support the farm business.”
That application was conditionally approved; the latest part to be considered by planners at a later date.
