Helping farmers tackle major parasitic disease in livestock
IMPROVED guidance and practical tools are required to help farmers to sustainably tackle the major problem of liver fluke infections in livestock, according to new research.
Scientists at Aberystwyth University have spoken in depth to farmers across Wales and say their early findings show there is a lot of uncertainty around managing this parasitic disease which affects the majority of sheep flocks and cattle herds in the UK.
Infections are believed to cost the UK livestock industry up to £300 million a year in reduced productivity levels, increasing mortality rates and veterinary costs.
In addition, there is growing resistance to the drugs used to treat the disease while changes in the climate are creating more favourable conditions where the parasite can thrive.
As part of a three-year project funded by the Biotechnology and Biological Sciences Research Council (BBSRC), researchers are developing new methods of controlling more effectively the parasitic worm which causes liver fluke.
They are pioneering the use of environmental DNA techniques to accurately detect the presence on farmland of mud snails which acts as an intermediate host between the parasite and livestock.
They are also carrying out close analysis of soil conditions on the farm to identify where the mud snail is most likely to live and thrive.
Principal Investigator Dr Rhys Aled Jones, from the University’s Department of Life Sciences, outlines the potential benefits of the research:
“Our aim is to develop sustainable, innovative strategies and provide farmers with better guidance and practical tools so they are better supported in their efforts to control liver fluke, which has become such a major problem on farms across Wales and the rest of the UK.
“If our research can help to control this parasite more effectively, there will be economic benefits through improved productivity as well as environmental benefits. Liver fluke is a harmful infection so there will be benefits too in terms of animal welfare and ensuring animals are healthy is one of the most effective ways of mitigating the environmental impact of livestock production systems.”
As part of the FlukeMAP project, launched in 2023, the University’s parasitologists and veterinary scientists have been working closely with 16 sheep farmers from across Wales.
Their extensive research has included carrying out in-depth interviews with the farmers, conducting comprehensive surveys assessing infection risks across farmland and monitoring infection levels in grazing sheep.
Several common themes have already emerged from analysis of the interviews and data gathered as part of the project, as Dr Gwen Rees from the Aberystwyth School of Veterinary Science explains:
“Liver fluke is a complicated disease, and the advice available to farmers from vets and industry is mixed and sometimes conflicting. Not surprisingly perhaps, we found there was a lot of uncertainty, with farmers often unsure about how to diagnose, when best to treat, where might be risky for infection and whether they had a fluke problem or not.
“As a result of their uncertainty around disease risk and how best to manage it, farmers often reported needing to use flukicides as a precautionary measure, but this can lead to flukicide resistance as well as medicine residues in the environment.”
Surveys assessing infection risk areas on farms further highlighted areas of uncertainty as Dr Rhys Aled Jones explains:
“Liver fluke risk is typically associated with wet condition. However, the timing and duration of these wet conditions are critical in determining infection risk. Our research also found strong links between soil characteristics, particularly pH and organic matter and the presence of the intermediate mud snail host which transmits liver fluke. These factors were rarely considered by farmers when assessing risk on land and this highlights a clear opportunity for improved guidance to support more accurate risk assessments.
“Accurately identifying fluke risk areas on farms can support more sustainable control strategies. These include optimising the use of diagnostic tests and treatments, and implementing targeted land and grazing management practices to reduce the likelihood of infection.”
Researchers are sharing their latest findings with an audience of farmers and industry representatives at the Royal Welsh showground on Wednesday 23 July).
Funded by the BBSRC and Aberystwyth University, FlukeMAP is a collaborative research project which brings together key partners including Farming Connect, the Welsh Veterinary Science Centre, the Farmers Union of Wales and Ridgeway Research.

Judicial review granted for hundreds of farmers and landowners in Wales
OVER three hundred Welsh farmers and landowners have been granted the right to legally challenge Green GEN Cymru’s ‘unlawful behaviour’ at the High Court.
The collective filed a judicial review application on behalf of the community groups, Justice for Wales and CPRW, on four separate grounds, including claims that the energy company has acted unlawfully and with disregard for biosecurity and the environment, while trying to gain access to private land to conduct surveys for three major overhead pylon routes.
The proposal will see the energy infrastructure and pylons spanning 200 km across Powys, Ceredigion, Carmarthen, and Montgomeryshire in Wales and across the Welsh border into Shropshire, in the West Midlands of England.

Mrs Justice Jefford granted permission on four grounds – including abuse of power and procedural impropriety – during the three-and-a-half-hour hearing at Cardiff Civil Justice Centre on Tuesday, January 20.
A two-day hearing is expected to take place in April 2026, date to be confirmed.
The judge also accepted an undertaking from Green GEN Cymru that it would not enter land using s.172 powers – the right given to acquiring authorities to enter land to conduct surveys or valuations under the Housing and Planning Act 2016 – until an urgent interim relief application hearing can be held.
Natalie Barstow, founder of Justice for Wales, said: “This is a moment of vindication. For months, we have been left feeling unsafe in our own homes and stripped of our power as farmers and landowners.
“This is not a protest against renewable energy; this is about standing up for what is right. Our right to dignity and to have a voice, and for the future of our land, wildlife, and livelihoods.
“Since we began this battle, hundreds of other farmers and landowners across Wales have come forward with similar stories, and we’ve been supported by many generous donations to fund the legal challenge. We knew we weren’t alone in our concerns, but the response demonstrates it is a far wider issue than we initially feared, and why it is so important that Green GEN’s conduct and protocols are properly scrutinised.
“We said we will not be bullied into submission, and this judgment is just the first foot forward in our fight for justice.”
Mary Smith, a lawyer at New South Law, the law firm representing the impacted communities, said: “Holding acquiring authority status does not entitle a company to disregard the limits of its statutory powers or the rights of the people affected.
“The Court’s decision confirms that Green GEN Cymru must be held to the same legal standards as any other public body when exercising intrusive powers over private land. This case is about restoring fairness, accountability, and respect for the communities whose livelihoods and environments are at stake.”

New rules to make Welsh lamb pricing clearer set to begin next week
Mandatory carcass grading and price reporting will be required in slaughterhouses from Wednesday, January 28
WELSH sheep farmers are set to see new rules introduced next week aimed at making the lamb market fairer and more transparent.
From Wednesday (Jan 28), slaughterhouses in Wales will be required to classify sheep carcasses and report prices using a standardised system. The Welsh Government says the move will improve consistency in grading, make price information easier to compare, and help build confidence for farmers selling stock.

Deputy First Minister Huw Irranca-Davies announced the change during the Farmers’ Union of Wales (FUW) Farmhouse Breakfast event at the Norwegian Church in Cardiff.
He said the measures would support the industry by ensuring a consistent methodology for classifying carcasses in slaughterhouses, promoting transparency, fairness and productivity within the sheep market.
“Our iconic Welsh lamb is celebrated around the world for its outstanding quality and high production standards,” he said. “These measures will implement a consistent methodology for classifying sheep carcasses in slaughterhouses, promoting transparency, fairness, and increased productivity within the sheep market.”
The regulations bring the sheep sector into line with rules already used for beef and pork.
Hybu Cig Cymru – Meat Promotion Wales chief executive José Peralta said the changes would allow for greater data capture and analysis and improve transparency within the supply chain.
He said: “The new regulations, which now align with a similar position for cattle and pigs, will allow for greater data capture and analysis to be undertaken and support increased transparency within the sector. As a sector we must seek all opportunities for greater transparency within the supply chain to ensure that choices can be made from an informed position.”
The Welsh Government says the new approach is part of a wider UK framework, with similar arrangements already operating elsewhere.
During his address, the Deputy First Minister also pointed to further changes expected in 2026, including the planned introduction of the Sustainable Farming Scheme, which the Welsh Government describes as a new partnership between the people of Wales and farmers.
The scheme is intended to support the sustainable production of food while also responding to the climate and nature emergency.
The Welsh Government has also confirmed its commitment to financial support during the transition, with up to £238 million committed to the Universal layer and the legacy Basic Payment Scheme in 2026.
Deputy First Minister Huw Irranca-Davies said: “I would like to reiterate the Welsh Government’s commitment to supporting Welsh family farms, not just in the short term but also in the long run. Our goal is to prioritise stability for the farming industry, ensuring to balance this with sustainability at its very core.”
He added that supporting farmers through the change would be a priority, with consistent advice and support offered across the sector.
Building fairness within the agricultural supply chain remains a key Welsh Government priority, which it says is also integral to food security.

Natural Resources Wales urges farmers to follow safe slurry spreading rules
NRW is reminding farmers across Wales to take key steps to prevent pollution as the organic manure spreading season re-opens.
During the autumn and winter “closed periods”, restrictions were in place to stop slurry and other high-nitrogen manures being spread, helping reduce the risk of agricultural pollution.
Grassland spreading can resume from Thursday (Jan 16), with spreading on tillage land re-opening on Friday (Jan 31). However, NRW said a number of controls under the Control of Agricultural Pollution Regulations (CoAPR) will remain in force until the end of February.
Those restrictions include limits on application rates — no more than 30m³ of slurry per hectare, or eight tonnes of poultry manure, in a single application — with at least three weeks required between applications.
Before spreading organic manure, producers must also carry out field inspections to assess weather and soil conditions, slope, ground cover and proximity to watercourses, to help reduce the risk of runoff.
Farm businesses are expected to plan and record all applications in their Nitrogen Management Plan to ensure nutrients match soil and crop need and remain within nitrogen limits.
Spreading is prohibited on waterlogged, flooded, snow-covered or frozen ground — including soil that has been frozen for more than 12 hours in the previous 24 hours.
NRW said its teams will continue to support farmers while monitoring compliance.
Simon Griffiths, team leader of NRW’s Agricultural Pollution Inspection Team, said: “As the closed periods come to an end, we want to remind farmers, tenants, landlords and contractors of the restrictions which remain in place until the end of February.
“This means anyone considering spreading organic manure needs to ensure the conditions are suitable before work starts.
“NRW is committed to protecting the environment and any instances of pollution will be investigated and appropriate enforcement action taken.”
NRW is urging farmers and members of the public to report pollution incidents immediately via its online “report it” form or by calling 0300 065 3000.
