Bluetongue Spreads Again in Europe: A Warning for Sheep and Cattle Traders

Bluetongue is back on the agenda across Europe. The disease is spreading again in the United Kingdom, and animal health experts warn that a more severe strain is pushing north through mainland Europe. For anyone who buys or sells sheep and cattle, the story matters because it changes how animals can move and how much supply reaches the market.

What bluetongue is and why traders should care

Bluetongue is a viral disease of ruminants. It affects cattle, sheep, goats and other animals such as deer and alpacas. It is spread by tiny biting midges, not by direct animal-to-animal contact, so it moves with the weather and the seasons.

The disease does not infect people and is not a food safety risk. Its impact is on farms and trade. Sick sheep can die, cattle can lose condition and milk, and pregnant animals can abort or give birth to weak young. Because bluetongue is a notifiable disease, an outbreak triggers movement controls that can quickly slow the flow of live animals.

United Kingdom: cases climb past 600

The UK is having a difficult 2026 to 2027 bluetongue season. The virus circulating is mainly serotype 3, known as BTV-3. The first cases of the new season were confirmed in England on 10 July 2026 and in Scotland on 8 August 2026, and numbers have risen fast since then.

By late August, confirmed cases across the UK had passed 500 and then climbed above 600. The south west of England has been the main hotspot.

Devon, Cornwall and Somerset have reported the largest share of English cases.
Most confirmed cases have been in sheep, with smaller numbers in cattle, alpacas and even a llama.
In Scotland, cases have been grouped in the Dumfries and Galloway area.

Farm vets in south west England have also reported trouble finding enough vaccine, in particular the Bultavo-3 product, just as demand for it has jumped.

Scotland tightens, then eases, movement rules

Scotland set up a Temporary Control Zone in its south west after cases appeared near Lockerbie and across Dumfries and Galloway. As of early September, the Scottish government listed 17 infected sheep and 62 infected cattle across 18 holdings in that zone.

The rules have shifted quickly:

From 22 August 2026, animals going to markets or shows in England and Wales had to return home the same day.
From 10 September 2026, the rules ease inside Scotland, so most cattle, sheep and goats no longer need vaccination or a test to leave the control zone for disease-free areas.

Officials expect the wider movement controls to stay in place until at least 9 September, then to relax as cooler autumn weather cuts the number of active midges. For now, live ruminants cannot be traded from Great Britain into the European Union, and movements into Northern Ireland are also blocked.

Mainland Europe: a more severe strain moves north

The picture on the continent adds a second layer of risk. Germany's Friedrich-Loeffler-Institut, the national animal health institute, reports that BTV-3 spread explosively through Germany in 2024, then calmed in 2025 as natural infection and vaccination built up immunity.

The new concern is a different virus type, serotype 8. Two strains are now circulating. An older, milder strain has returned from France, while a newer strain known as BTV8-FRA2023 is causing more serious illness. This newer strain has moved from southern France through Switzerland, Italy and Austria into southern Germany, where it has been confirmed in several regions.

Vets in Austria say this new strain has caused worse symptoms in some animals than BTV-3. Experts expect it to keep spreading north through the autumn of 2026, and they warn it is a real threat to sheep and cattle. Vaccination is seen as the best defence, but no vaccine fully stops infection.

What buyers and sellers should watch

The common thread across the UK and the continent is uncertainty. Rules can change within days, and each new control zone can cut off a supply region or add cost to a movement.

Check the disease status and movement rules for both the origin and the destination before agreeing any deal on live sheep or cattle.
Expect tighter movement controls in warm months and some easing as temperatures fall and midge activity drops.
Watch vaccine availability, since shortages in one region can slow trade and raise costs.
Factor in that Great Britain cannot currently send live ruminants to the EU, which limits some trade routes.
Keep an eye on the spread of the newer serotype 8 strain in central Europe, as it can affect sheep and cattle supply in the months ahead.

Bluetongue does not stop meat from reaching shops, but it does make the trade in live animals harder to plan. Traders who follow the outbreak maps and the rule changes will be better placed to keep deals moving.
