Defra has confirmed the first bluetongue serotype 3 case of the 2026 to 2027 season in England, with a positive result recorded on 10 July 2026 after suspicious clinical signs were investigated in Staffordshire. According to the department’s gov.uk update, the affected animal was a ewe showing head swelling, drooling, crusty nostrils and lameness in all four feet. The department says this is the first confirmed infection of the summer period, counted from 1 July 2026. It also states that there have been no cases so far this season in Wales, Scotland or Northern Ireland. The standing public guidance remains unchanged: suspected cases should be reported quickly and livestock keepers should remain alert to clinical signs.
Defra records one case in England for the 2026 to 2027 bluetongue season. The same notice directs readers to the official bluetongue case map, which shows premises in Great Britain where one or more animals have tested positive by PCR for BTV-3, BTV-8 or BTV-12 since 1 July 2024. That mapping is a working tool for the sector rather than background material. For farmers, private vets, livestock markets and hauliers, the immediate task is to check both current case data and current zone status before arranging animal movements, breeding activity or sales.
Before the new season opened, three late English confirmations were logged at the end of the 2025 to 2026 season. Defra reported a calf with behavioural and neurological signs on 3 June 2026, a blind calf in Staffordshire on 9 June 2026 that was otherwise clinically well, and a calf in Lancashire born blind on 1 June and confirmed positive on 23 June 2026, with additional neurological signs noted in that final case. Those cases closed a much heavier outbreak year. Defra says Great Britain recorded 348 cases between 11 July 2025 and 23 June 2026, comprising 324 in England and 24 in Wales, with none in Scotland. Northern Ireland separately confirmed five BTV-3 cases, according to DAERA.
Defra’s risk assessment says the midges that spread bluetongue became active again on 31 March 2026. Following recent warm weather, cumulative temperatures are now judged high enough for the virus to develop inside midges, which means onward transmission is possible. The guidance also notes that infection can pass through germinal products, including semen, ova and embryos. The department adds that temperatures in many parts of nearby continental Europe are also now high enough for infected midges to become infectious after completing the extrinsic incubation period. On that basis, Defra rates the overall risk of bluetongue virus entering from all routes as medium, while assessing the specific risk from airborne incursion as negligible.
Control measures remain broad rather than localised. Defra says the whole of England is in a bluetongue restricted zone, which means susceptible animals may move within England without a specific bluetongue licence or pre-movement testing. The position is different for germinal products: freezing semen, ova or embryos anywhere in England requires a specific licence and testing, with sampling, postage and laboratory costs falling to the keeper. Wales is also operating under an all-Wales restricted zone introduced from 10 November 2025. According to the Welsh Government rules referenced by Defra, livestock can move between England and Wales without bluetongue vaccination or additional mitigation, but donor animals for germinal products must still be tested before freezing and marketing.
Cross-border movements into Scotland remain tighter. The gov.uk notice states that any movement of bluetongue-susceptible animals from a restricted zone in England, Wales, Northern Ireland or the Isle of Man to a final destination in Scotland must comply with general movement licence EXD608(EW), including temporary movements for shows, markets and other gatherings. Those Scottish controls came into force on 1 June 2026 and are due to remain in place until at least 9 September 2026. For producers and hauliers, that turns movement planning into a licensing and compliance exercise, especially where animals are leaving England or Wales for sale, exhibition or onward finishing.
Defra’s latest notice keeps vaccination and biosecurity at the centre of the response. The department directs keepers to its BTV-3 vaccination guidance and to separate advice on slowing the spread of disease. It also signposts movement licences within restricted zones, slaughterhouse arrangements, rules for germinal products, and DAERA licensing for certain movements from Northern Ireland to Great Britain. The notice makes clear that ordinary livestock identification and movement controls continue to apply alongside disease restrictions. Cattle, bison, buffalo, sheep, goats and deer keepers must still follow tagging, reporting and record-keeping requirements, while the Animal and Plant Health Agency remains the contact point for camelid keepers or for those uncertain about the rules. Importers are directed to the standing UK rules on imports, exports and EU trade in animals and animal products.
The current response sits within Defra’s disease control framework for England and is supported by webinars, leaflets, posters and other official material intended to standardise reporting and on-farm practice. In policy terms, the government approach combines country-wide restriction zones with targeted licensing, testing of higher-risk reproductive material, and guidance that can be updated quickly as vector activity changes. Recent history explains why officials are treating the 10 July 2026 case as significant. Defra recorded 163 cases in the 2024 to 2025 season, including one BTV-12 case in England confirmed on 7 February 2025, and 126 BTV-3 cases on 73 premises between November 2023 and March 2024, the first UK incursions for more than 15 years. Before that, the last confirmed outbreak was BTV-8 in 2007 to 2008. The result is a control regime that now assumes recurring seasonal pressure rather than a one-off event.
