Bluetongue cases rise in England and Wales, July 2026
Defra’s latest gov.uk update shows 24 confirmed bluetongue cases in the UK since 1 July 2026. Twenty-one are in England, three are in Wales, and there have been no cases in Scotland or Northern Ireland in this season so far. If you are coming to this story fresh, bluetongue is a viral disease that affects livestock such as sheep and cattle. It matters because it can make animals seriously ill, disrupt breeding and movement, and force farmers to work through testing, licences and zone rules at speed.
The recent pattern is clustered rather than random. Defra’s July updates record cases in Devon, Somerset, Cheshire and Staffordshire in England, and in Newport, Powys and the Vale of Glamorgan in Wales. Some animals had obvious signs such as fever, drooling, mouth ulcers, swollen faces, lameness and severe lethargy. Others tested positive during private pre-movement checks or breeding-related testing and showed no signs at all. That matters because bluetongue is not always picked up by sight alone. The first confirmed case of this summer’s outbreak season was announced on 10 July 2026 after a ewe in Staffordshire showed head swelling, drooling, crusty nostrils and lameness. From there, the numbers built quickly across farms in the South West and beyond.
The sheep cases are especially striking. Defra’s notes describe animals with crusting around the muzzle, nasal discharge, swelling, sore feet, sudden weight loss and, in some flocks, deaths. Cattle have also tested positive, with some showing fever, irregular gait or ulcers in the mouth, and one Welsh case was investigated after abortions in a group of heifers. In Cheshire, two calves born blind and unable to stand properly were among the confirmed BTV-3 cases. **What this tells you:** officials are watching both illness and silent transmission. Where farmers report suspicious clinical signs, Defra funds diagnostic testing for up to three affected animals. There is also a bluetongue case map for Great Britain, showing premises where animals have tested positive by PCR for serotypes 3, 8 or 12.
Why has the risk risen now? Defra says the midges that spread bluetongue became active again on 31 March 2026. After recent warm weather, temperatures are now high enough for the virus to develop inside those midges, which means onward transmission is possible again. The department also says temperatures in nearby continental Europe are high enough for the same process there. In plain English, that means infected midges across the Channel have had better conditions to become infectious. Defra’s formal rating still puts the overall risk of incursion from all routes at medium, while rating airborne incursion as negligible, but the summer conditions are clearly more favourable for spread than they were a few months ago.
If you hear the phrase restricted zone and picture a total halt to farm life, that is not quite what these rules mean. England is now a country-wide bluetongue restricted zone, and Wales is too. According to Defra, animals can move within England without a specific bluetongue licence or pre-movement testing. The Welsh Government’s all-Wales restricted zone, which began just after midnight on 10 November 2025, also allows livestock to move between England and Wales without bluetongue vaccination or other mitigation measures. **What this means:** the rules are trying to manage risk, not freeze all movement. The stricter part is around germinal products such as semen, ova and embryos, because the virus can spread that way as well as through midges.
That is why the paperwork becomes more exact when breeding material is involved. In England, a specific licence is needed to freeze germinal products anywhere in the country, and testing is required. Keepers are responsible for the cost of sampling, postage and testing. Wales keeps similar restrictions in place for donor animals before freezing and marketing germinal products. Scotland is operating with tighter border protections. Movements of bluetongue-susceptible animals from restricted zones in England, Wales, Northern Ireland or the Isle of Man must meet the conditions of general licence EXD608(EW). Those controls came into force on 1 June 2026 and, according to the gov.uk update, will stay in place until at least 9 September 2026.
For farmers, this is where animal health meets daily admin. Defra directs keepers to guidance on movement licences, designated slaughterhouses, vaccination, biosecurity and record-keeping for cattle, sheep, goats and deer. The Animal and Plant Health Agency says camelid keepers, including people with alpacas or llamas, should contact APHA directly if they are unsure of the rules. There is a practical lesson here for the rest of us too. Disease control in farming is not only about what happens when animals are visibly sick. It is also about tracing movements, checking breeding material, keeping records straight and spotting problems early enough to limit wider spread.
This summer’s numbers are worrying on their own, but the longer view matters just as much. Defra recorded 348 bluetongue cases in Great Britain in the 2025 to 2026 season, including 324 in England and 24 in Wales, with no cases in Scotland. Northern Ireland separately confirmed five BTV-3 cases in that period. In the previous season, Defra confirmed 163 cases linked to England and high-risk moves in Wales, including one BTV-12 case confirmed on 7 February 2025. Go back one more season and you can see why officials are treating this so seriously. Between 10 November 2023 and 3 March 2024, Defra confirmed 126 BTV-3 cases in England on 73 premises, the first UK bluetongue incursions for more than 15 years. So this is not a one-week farm alert. It is a continuing animal health story about weather, trade, biosecurity and how quickly local outbreaks can turn into national rules.
If you want the simplest takeaway, it is this: report signs, check the zone maps, and do not assume the rules are the same for every kind of movement. The gov.uk page brings together the latest case totals, the bluetongue zone map, vaccination advice, webinars and the disease control framework used by Defra. For readers outside farming, the story is worth following because outbreaks like this can raise farm costs, slow breeding and transport, and put more pressure on the systems that help food production keep moving. It is a reminder that animal health policy can feel technical on paper, but on the ground it shapes how farms work every day.
