Defra and the Animal and Plant Health Agency, in an update last revised on 24 July 2026, put the UK total for the 2026 to 2027 bluetongue season at 24 cases since 1 July 2026. The published split is 21 cases in England and 3 in Wales, with no cases reported in Scotland or Northern Ireland in the current season. (gov.uk) For livestock keepers, veterinary practices and market operators, the significance lies in the control structure around the cases. England and Wales are both operating under country-wide restricted zones, so the main compliance question is less about whether a holding falls inside a small local control area and more about which movement route, testing duty or licence applies to the planned transaction. (gov.uk)
Defra records 10 July 2026 as the first confirmed infection of the summer, after a ewe in Staffordshire presented with head swelling, drooling, crusty nostrils and lameness. By the 24 July update, later confirmations had been published for Devon, Somerset and Cheshire in England, and for Newport, Powys and the Vale of Glamorgan in Wales. (gov.uk) The case notes matter because they show both the clinical picture and the surveillance routes now picking up BTV-3. Defra's published July reports describe fever, lethargy, excessive salivation, mouth lesions, facial swelling, lameness, nasal discharge, abortions and calf neurological signs, but Wales also recorded detections through private pre-movement and embryo-transfer testing where no obvious clinical signs were present. That makes early reporting and planned testing just as important as visible symptom recognition. (gov.uk)
Defra says the midges that spread bluetongue became active again on 31 March 2026, and that recent warm weather means cumulative temperatures are now high enough for the virus to develop inside the vector. In departmental terms, onward transmission is now possible, and infection can also occur through germinal products including semen, ova and embryos. (gov.uk) The same update says temperatures in parts of nearby continental Europe are also high enough for the virus to have completed its extrinsic incubation period in infected midges, increasing the chance of transmission from midges blown across the Channel. Even so, Defra's current formal assessment keeps the risk of incursion from all routes at medium, described as occurring regularly, while rating airborne incursion as negligible. (gov.uk)
In England, the whole country is now within a bluetongue restricted zone. That means susceptible animals can move within England without a bluetongue-specific licence or pre-movement testing, while disease control is being managed through a national restricted-zone model rather than smaller local zones. (gov.uk) That easement does not extend to breeding material. Defra states that freezing germinal products anywhere in England still requires a specific licence and testing, with keepers meeting sampling, postage and laboratory costs. The equivalent Welsh position is similar in effect: the all-Wales restricted zone, introduced from 00:01 on 10 November 2025, allows livestock movement between England and Wales without vaccination or other mitigation measures, but donor animals for germinal products must still be tested before freezing and marketing. (gov.uk)
Scotland remains the clearest internal UK exception. Scottish Government guidance says the 2026 vector-active control period runs from 1 June to 9 September 2026, and that susceptible animals moving from restricted zones in England, Wales, Northern Ireland or the Isle of Man to live in Scotland must comply with the general movement licence EXD608(EW). Animals moving for immediate slaughter follow a different licence route. (gov.scot) The practical effect is that cross-border movements to Scotland still need active planning even where movements within England or Wales have been simplified. Gov.Scot says blood samples for Scotland-bound animals must be taken no more than seven calendar days before movement, negative results are required, and the supporting paperwork must travel with the animals; the same control logic also applies to temporary movements involving shows, sales and gatherings. (gov.scot)
Defra continues to fund diagnostic testing for up to three affected animals where suspect clinical signs are reported, an arrangement that lowers the first barrier to investigation on farm. That matters in a season where published detections have come through more than one route, from obvious clinical disease in sheep and cattle to private pre-movement screening and reproductive testing. (gov.uk) The 24 July government update also keeps vaccination and biosecurity in the foreground. Defra links keepers and veterinarians to BTV-3 vaccination guidance, disease-prevention advice, and the statutory identification and movement rules for cattle, sheep, goats and deer, while APHA remains the contact point for camelids or cases where the rule set is unclear. (gov.uk)
One important reading point in the government material is that domestic restricted-zone easements do not automatically carry across to trade activity. Defra directs operators to separate guidance on imports, exports and EU trade of animals and animal products, and it also signposts separate DAERA material for certain animal movements from Northern Ireland to Great Britain. (gov.uk) Operationally, Defra points readers back to three reference sources: the PCR case map for confirmed premises in Great Britain, the zone map for checking local status, and the disease control framework in England that underpins official response measures. For compliance teams, auctioneers and breeding businesses, those documents are the working reference rather than the headline case tally alone. (gov.uk)
Historical data place the 2026 to 2027 season in a longer run of confirmed detections rather than a stand-alone event. Defra records 348 bluetongue cases across Great Britain in the 2025 to 2026 season, including 324 in England and 24 in Wales, while Northern Ireland separately recorded five confirmed BTV-3 cases. The previous 2024 to 2025 season brought a total of 163 cases, including one BTV-12 confirmation in England. (gov.uk) Defra's earlier records also show 126 BTV-3 cases on 73 English premises between 10 November 2023 and 3 March 2024, the first UK incursions for more than 15 years after the 2007 to 2008 BTV-8 outbreak. Against that record, the current control model is clear: simpler domestic movement rules inside national restricted zones, tighter treatment of Scotland-bound moves and germinal products, and continued emphasis on rapid reporting, vaccination planning and record keeping as the vector-active period continues.
