Bluetongue Returns to UK Farms: What Meat Traders Need to Know

A new bluetongue season has opened on farms in the United Kingdom, and the virus is spreading again in both sheep and cattle. For anyone trading live animals, breeding stock or genetics in Europe, this is worth watching closely.

A new season, and cases are climbing

The UK's 2026/27 bluetongue season runs from 1 July to 30 June. The first case of the season was confirmed on 10 July 2026, when a ewe in Staffordshire, England, showed head swelling, drooling, crusty nostrils and lameness in all four feet.

More cases followed quickly. On 14 July, the Department for Environment, Food and Rural Affairs (Defra) confirmed two calves in Cheshire born blind and with neurological signs, plus a cow in Devon with a crusted muzzle and swollen eyes.

By 24 July, Defra said the count had grown. The picture at that point was:

17 confirmed cases in England
2 confirmed cases in Wales
19 cases in total across the UK
No cases in Scotland or Northern Ireland

All the cases are the BTV-3 strain of the virus. Defra said it will keep funding diagnostic testing for up to three affected animals when farmers report suspect signs.

What bluetongue is

Bluetongue is a viral disease that affects ruminants such as sheep, cattle, goats and deer, as well as camelids like llamas and alpacas. It is spread mainly by biting midges. It is not contagious from animal to animal by direct contact, and it does not affect people or food safety.

Sheep usually suffer the most obvious illness. Cattle often show few signs, yet they can carry and spread the virus for several weeks. Common symptoms include:

Fever and lethargy
Drooling and ulcers around the mouth and nose
Swelling of the head
Lameness
Milk drop in dairy animals
Abortions, stillbirths and calves or lambs born weak, deformed or blind

Why it matters for the meat trade

Even though bluetongue is not a food safety risk, outbreaks bring real commercial pain. The main problem is trade and movement restrictions.

The whole of England is a bluetongue restricted zone. Animals can still move within England without a special licence or pre-movement test, but there are extra rules for moving stock to other parts of the UK. An all-Wales restricted zone has been in place since 10 November 2025, and moving susceptible animals from a restricted zone into Scotland needs a general licence.

There are also controls on germinal products such as semen, ova and embryos, which must be tested before they are frozen and traded. For buyers and sellers of breeding stock and genetics, that adds cost and paperwork.

The reproductive damage matters too. Abortions and deformed calves reduce the number of healthy animals born, which can tighten future supply of both cattle and sheep.

Warm weather raises the risk for Europe

The midges that carry bluetongue became active again in the UK on 31 March 2026. After a spell of warm weather, experts say temperatures are now high enough for the virus to develop inside the midges, so onward spread is possible.

The risk is not only local. Defra warned that temperatures across nearby continental Europe are also high enough for the virus to develop in midges there. That raises the chance of infected midges being blown across the English Channel. In the previous 2025/26 season, Great Britain recorded 348 bluetongue cases, so the disease is far from new to the region.

What buyers and sellers should watch

For meat and livestock traders working with UK and European supply, a few points are worth keeping in mind:

Check the restricted-zone status and licensing rules before arranging any live animal or breeding stock movement.
Ask about the vaccination status of the animals. Vaccines for BTV-3 are available in good supply, but a BTV-3 vaccine gives no protection against BTV-8, and vaccination takes time to build full protection.
Remember that bluetongue is a notifiable disease. In the UK, suspected cases must be reported to the Animal and Plant Health Agency immediately, and failing to do so is an offence.
Watch for delayed reproductive losses, which can affect the number of animals coming to market months from now.

The Animal and Plant Health Agency says vaccination, planned with a vet, is the most effective way to protect animals. With cases rising and the warm season still ahead, that advice is likely to shape trade in UK and European livestock over the coming weeks.
