Defra has confirmed 8 cases of bluetongue serotype 3 in England in the 2026 to 2027 outbreak season, measured from 1 July 2026. In its latest official update, the department said there have been no cases this season in Wales, Scotland or Northern Ireland. For livestock keepers, the immediate point is that the disease position is no longer being handled as a localised issue. England remains under a country-wide restricted zone, which changes how movements are managed but does not remove reporting duties, biosecurity expectations or the need to follow separate rules for germinal products and cross-border trade.
The first confirmed case of the current season was recorded on 10 July 2026, when a ewe in Staffordshire tested positive after presenting with head swelling, drooling, crusting around the nostrils and lameness in all four feet. Defra said the clinical signs and laboratory findings marked the first confirmed infection of the summer. Two further cases were confirmed on 14 July 2026. These involved two calves in Cheshire, born blind and unable to stand properly with other neurological signs, and one cow in Devon showing muzzle crusting, swollen and reddened eyes, and reddening of the teats. Defra's account makes clear that testing followed reports of suspicious clinical signs rather than routine screening alone.
A further five cases were confirmed on 16 July 2026, centred in Devon and Somerset. According to Defra, these included a dairy heifer in Somerset, a lamb in Devon, two separate groups of sheep in Devon, and a group of sheep in Somerset. Reported signs included facial swelling, drooling, mouth and muzzle lesions, fever, lameness and rapid loss of body condition. The latest update also records animal deaths within two of those confirmations. In one Devon group, Defra said one animal had died and two more were showing similar signs. In the Somerset group, one animal had also died. The detail is operationally important because it shows that the current season is producing visible clinical disease in both cattle and sheep, rather than only laboratory detections without symptoms.
Defra's risk assessment has hardened with the change in season and recent temperatures. The department said the midges that spread bluetongue became active again on 31 March 2026 and that cumulative temperatures are now high enough for the virus to develop inside the vector, meaning onward transmission is possible. The official update also notes that infection can occur through germinal products, including semen, ova and embryos. Defra added that temperatures in nearby continental Europe are now high enough in many areas for the virus to have developed inside midges there as well. Even so, the department's current judgement is that the overall risk of incursion from all routes remains medium, while the specific risk of airborne incursion is rated negligible.
For movement controls, the most consequential measure remains the England-wide restricted zone. Defra states that animals can move within England without a specific bluetongue licence or pre-movement testing. That is a major simplification for routine domestic trade, but it applies only to live animal movements within England and should not be read as a general lifting of controls. Germinal products are treated differently. Defra says a specific licence is required anywhere in England to freeze semen, ova or embryos, and testing is mandatory. Keepers are responsible for sampling, postage and testing costs. In practice, that leaves breeding businesses and veterinary operators with a more regulated position than ordinary livestock movements inside the English zone.
The devolved picture remains important for any business moving stock across borders. Wales has operated an all-Wales restricted zone since 00:01 on 10 November 2025. Under that arrangement, livestock movements between England and Wales no longer require bluetongue vaccination or other mitigation measures, although restrictions on germinal products continue and donor animals must still be tested before freezing and marketing. Scotland remains subject to tighter entry conditions. Defra states that movements of bluetongue-susceptible animals from a restricted zone in England, Wales, Northern Ireland or the Isle of Man into Scotland must comply with 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. The rule covers temporary movements to shows, markets and gatherings as well as final destination moves.
Defra continues to direct keepers to its BTV-3 vaccination guidance and its advice on slowing spread through biosecurity. The department also says it will fund diagnostic testing for up to three affected animals where suspect clinical signs are reported. That is a practical point for farm businesses, because it lowers the cost barrier to early reporting when symptoms appear. The wider compliance framework remains in place around identification, movement recording and species-specific rules for cattle, sheep, goats and deer. Defra advises camelid keepers, including those with llamas or alpacas, to contact the Animal and Plant Health Agency if they are unsure how the rules apply. The department has also published case maps, zone maps, webinars and operational materials so that keepers, vets and markets can match day-to-day decisions to the current disease controls.
The present outbreak season follows a much larger year in 2025 to 2026, when 348 cases were confirmed in Great Britain. Defra's figures show 324 cases in England and 24 in Wales during that period, while Scotland recorded none. Northern Ireland separately confirmed 5 BTV-3 cases. Earlier seasons also show sustained activity, including 163 cases in 2024 to 2025 and 126 BTV-3 cases in 2023 to 2024, which Defra described as the first UK BTV incursions for more than 15 years. That history matters because the current regime is not a short-lived emergency response. It is an established disease-control framework that now shapes movement, breeding and reporting decisions across Great Britain. Defra's standing advice is for keepers and veterinarians to remain alert to signs of bluetongue, report suspicions promptly, check the official maps before movements, and confirm import, export and germinal product conditions before animals or animal material are moved.
