Defra’s latest bluetongue update sets out a clear position for the 2026 to 2027 season. Since 1 July 2026, 24 cases of bluetongue serotype 3 have been confirmed across the UK, with 21 cases in England and 3 in Wales. No cases have been recorded in Scotland or Northern Ireland during the current season. The first confirmed case of the summer was published on 10 July 2026. Defra is asking keepers to stay alert for signs of disease and report suspicion promptly. Where animals show suspect clinical signs, Defra will fund diagnostic testing for up to three affected animals, which lowers the immediate cost barrier to early reporting.
The published case history shows a concentrated run of detections through July, particularly in Devon and Somerset, alongside confirmed cases in Staffordshire, Cheshire and several Welsh locations including Powys, Newport and the Vale of Glamorgan. Defra’s updates describe infection in sheep, cattle, calves and heifers, with some animals showing marked clinical signs and others identified through private testing before movement or in connection with embryo transfer. That pattern matters for keepers, markets and breeding businesses. The official record shows that bluetongue is not presenting in a single way. Defra has reported fever, drooling, mouth ulcers, facial swelling, lameness, nasal discharge and lethargy in a number of cases, while some infected animals had no obvious signs at the point of testing. For compliance purposes, visual inspection on its own is therefore not enough in every setting.
Defra’s risk assessment remains tied to vector activity. The department states that the midges which spread bluetongue became active again on 31 March 2026 and that recent warm weather has pushed cumulative temperatures high enough for the virus to develop inside the insect, making onward transmission possible. The government also notes that temperatures across nearby continental Europe are now high enough in many areas for the virus to have completed its extrinsic incubation period in infected midges. In practical terms, that raises concern about fresh transmission pressure during the summer months. Defra adds that infection can also occur through germinal products, meaning semen, ova and embryos remain part of the disease-control picture as well as live animal movement.
On the formal risk scale, Defra says the overall risk of bluetongue incursion from all routes remains medium, meaning it occurs regularly. At the same time, it separately describes the risk of airborne incursion as negligible. Read together, those statements point to a control model that is focused less on windborne spread and more on seasonal vector activity, animal movements and breeding material. This helps explain why the current policy response is built around restricted zones, testing rules and licensing rather than a full stop on all movement. The official approach is to keep trade moving where the risk can be managed, while maintaining tighter checks where disease could be carried across borders or preserved in germinal products.
For England, the immediate rule is straightforward. The whole country is now classed as a bluetongue restricted zone, and animals can move within England without a specific bluetongue licence or pre-movement test. That is a significant operational point for keepers and hauliers because it removes an extra administrative step for domestic movements inside England. The position is tighter for germinal products. Defra states that a specific licence is required to freeze semen, ova or embryos anywhere in England, and testing is mandatory. The keeper is responsible for sampling, postage and laboratory costs. In policy terms, England has moved to a broad internal restricted-zone model, but it has not relaxed the controls around breeding material.
Wales is operating under a similar country-wide structure. The Welsh Government’s all-Wales restricted zone has been in force since 00:01 on 10 November 2025. Under that arrangement, livestock can move between England and Wales without bluetongue vaccination or other mitigation measures that previously applied to cross-border trade. That easing does not extend to all disease-control activity. The Welsh position, as cited in Defra’s update, keeps restrictions on germinal products in place and continues to require testing of donor animals before freezing and marketing. The stated purpose is quality assurance and the reduction of longer-term transmission risk, which keeps breeding operations under a more controlled regime than routine livestock movements.
The sharpest cross-border controls now sit on movements into Scotland. Defra’s update states that any movement of bluetongue-susceptible animals from a restricted zone to Scotland, including temporary moves for shows, markets and gatherings, must meet the conditions of general movement licence EXD608(EW). Those controls came into force on 1 June 2026 and are due to remain in place until at least 9 September 2026. This matters because England, Wales, Northern Ireland and the Isle of Man are all treated as bluetongue restricted zones for this purpose. A keeper may therefore face few extra disease-control steps for movement within England, but a very different legal position when the destination is Scotland. Defra also directs readers to separate arrangements for some licensed movements from Northern Ireland to Great Britain through DAERA.
Defra’s update makes clear that bluetongue controls sit alongside the wider livestock traceability system rather than replacing it. Separate identification and movement rules continue to apply for cattle, bison and buffalo, sheep and goats, and deer. The Animal and Plant Health Agency remains the contact point for camelid keepers, including those with llamas and alpacas, and for anyone unsure which rules apply to their holding. The broader context is that the UK is no longer dealing with isolated events. Defra records 348 cases in Great Britain during the 2025 to 2026 season, including 324 in England and 24 in Wales, with a further 5 confirmed cases in Northern Ireland. The previous season brought 163 cases, and the 2023 to 2024 season saw 126 BTV-3 cases on 73 premises, the first UK bluetongue incursions in more than 15 years. Current policy is therefore being applied against a sustained recent history, using Defra’s disease control framework in England, vaccination guidance, biosecurity advice and official case mapping to manage a disease that is now an established regulatory concern for livestock keepers.
