Bluetongue in England: 8 Cases and July 2026 Rules

As of Friday 17 July 2026, Defra says England has recorded 8 cases of bluetongue serotype 3 since the new season began on 1 July 2026. The newest confirmed cases are in Devon, Somerset, Cheshire and Staffordshire, while Wales, Scotland and Northern Ireland have reported no cases in the 2026 to 2027 season so far. (gov.uk) If you do not work with livestock, that may sound like a very specialist story. It is, but it also shows how animal disease controls work in practice. The rules are designed to slow spread during the higher-risk part of the year, when biting midges are mainly active between April and November. (gov.uk)

Bluetongue is a notifiable disease caused by bluetongue virus, and it is mainly spread by biting midges. It affects sheep, cattle, other ruminants such as deer and goats, and camelids such as llamas and alpacas. (gov.uk) **What it means:** you are not looking for one single symptom. GOV.UK says sheep may show mouth or nose ulcers, drooling, swelling, fever, lameness, abortions and death. Cattle may show lethargy, crusting around the nostrils and muzzle, redness of the mouth or eyes, fever, milk drop and pregnancy problems. Calves and lambs can be born weak, deformed or blind if infection happens before birth, and adult cattle may carry infection for weeks while showing little or no illness. (gov.uk)

The latest update helps explain why officials are worried. On 16 July 2026, Defra confirmed five new BTV-3 cases after suspicious clinical signs were reported: a dairy heifer in Somerset, a lamb in Devon, two separate Devon sheep groups and a group of sheep in Somerset. Defra’s case notes say affected animals showed signs including facial swelling, drooling, fever, mouth lesions, stiffness or lameness, and two animals died. (gov.uk) That followed two cases confirmed on 14 July 2026, involving calves in Cheshire born blind and unable to stand properly, and a cow in Devon with crusting and swollen eyes. The first confirmed case of the summer was then listed on 10 July 2026: a ewe in Staffordshire with head swelling, drooling and lameness in all four feet. (gov.uk)

The science sounds technical, but the basic point is simple. Defra says the midges that spread bluetongue became active again on 31 March 2026, and recent warm weather has pushed temperatures high enough for the virus to develop inside them. That means onward transmission is now possible. (gov.uk) **What this means for summer:** warmer weather turns this from a monitoring exercise into a live disease risk. Defra also says temperatures in parts of continental Europe are high enough for infected midges there to become infectious, which raises concern about wind-borne midges crossing the Channel. Even so, the department says the overall risk of incursion from all routes remains medium, while the risk of airborne incursion is negligible. (gov.uk)

For farmers in England, one of the biggest rules is already in place: the whole of England is a bluetongue restricted zone. That sounds severe, but it does not mean livestock movements stop. Animals can move within England without a specific bluetongue licence or pre-movement testing. (gov.uk) The fine print still matters. Freezing semen, ova or embryos anywhere in England needs a specific licence and testing, and keepers must pay for sampling, postage and testing. Wales is also a country-wide restricted zone, so livestock can move between England and Wales without bluetongue vaccination or mitigation measures, but Scotland keeps tighter controls: movements of susceptible animals from a restricted zone to Scotland must meet licence EXD608(EW) conditions until at least 9 September 2026. (gov.uk)

Vaccination is part of the official response, but it is not something keepers should do without veterinary oversight. GOV.UK says there are three authorised BTV-3 vaccines for use in the UK - Bluevac-3, BULTAVO 3 and Syvazul BTV 3 - and a vet must prescribe them. In England, Wales and Scotland, keepers must record every vaccinated animal, keep those records for at least five years and report vaccinations within 48 hours. (gov.uk) Biosecurity still matters alongside vaccination. Defra and APHA advise keepers to source livestock responsibly, stay alert to signs of disease, house animals in buildings that keep out biting midges where possible, especially at dawn and dusk, maintain good hygiene, and stop dogs or cats chewing potentially infected material such as afterbirth. (gov.uk)

If you suspect bluetongue, you must report it straight away. GOV.UK says the disease is notifiable, so failing to report it is against the law, and Defra funds diagnostic testing for up to three affected animals when suspect clinical signs are reported. APHA can also help keepers who are unsure about movement or identification rules, including those who keep camelids. (gov.uk) There is a bigger lesson in the numbers. Great Britain recorded 348 cases in the 2025 to 2026 season, after 163 cases in 2024 to 2025 and 126 cases in the 2023 to 2024 season, which Defra said were the first UK BTV-3 incursions for more than 15 years. **What it means:** if you keep livestock, bluetongue is now part of the regular planning calendar, not just an occasional emergency headline.
