New Bluetongue Case Confirmed in Cumbria as Midge Risk Rises
A new case of bluetongue has been confirmed in Cumbria as warmer weather increases the risk from biting midges.
The latest case of BTV-3 was confirmed in the county on May 8, 2026. Government updates also say the midges that spread bluetongue became active again on March 31, 2026, as temperatures began to rise.
Bluetongue is a viral disease that affects animals including cattle, sheep, goats, deer, llamas and alpacas. It does not affect people, and it does not make meat or milk unsafe to eat or drink.
What Is Bluetongue?
Bluetongue is an animal disease spread mainly by infected biting midges.
It can affect several types of livestock, but sheep often show the clearest signs of illness. Cattle may show mild signs or no signs at all, but they can still carry the virus for a period of time.
This makes the disease difficult to manage. Animals may appear healthy while still posing a risk of spreading infection through midges.
The current case in Cumbria involves BTV-3, one of the bluetongue virus types being monitored across Great Britain.
Why Midge Activity Matters
Bluetongue is closely linked to the weather because midges are more active in warmer conditions.
Government guidance says experts still consider the current risk of midge spread to be very low, because it has not yet been warm enough for long enough for the virus to develop inside midges. However, midges can still become infected, and the situation can change as temperatures rise.
This is why farmers and livestock keepers are being urged to stay alert as spring moves towards summer.
The disease can also be spread through germinal products, such as semen, ova or embryos, which means movement and breeding controls remain important.
Recent Cases in Cumbria
The latest update follows earlier confirmed cases in Cumbria this year.
Two new BTV-3 cases were confirmed in the county between April 30 and May 1, 2026. The new case confirmed on May 8 adds to ongoing concern among livestock keepers in the region.
Cumbria has a large farming community, with many cattle and sheep farms across rural areas. Any confirmed case can therefore create concern for farmers, vets, markets and businesses connected to agriculture.
Signs Farmers Should Watch For
Livestock keepers should watch for signs of bluetongue in their animals.
In sheep and cattle, possible signs can include fever, lameness, discharge from the eyes or nose, drooling, ulcers or sores around the mouth and nose, reduced milk yield, lethargy and not eating. Bluetongue can also cause abortion, stillbirths and deformities in calves and lambs.
Young animals may be born weak, blind or deformed if infection passes from the mother during pregnancy.
Any suspected case must be reported. Bluetongue is a notifiable disease, which means livestock keepers are legally required to report concerns to the Animal and Plant Health Agency.
No Risk to People or Food Safety
Although bluetongue can be serious for animals, it is not a human health risk.
People cannot catch bluetongue from infected animals. Meat and milk from infected animals are also safe to eat and drink.
The main concern is animal health, farm management and the potential impact on livestock movement.
Farmers Urged to Stay Vigilant
The new Cumbria case comes at a time when midge activity is increasing.
For local farmers, the key advice is to monitor animals closely, check movement rules before transporting livestock, and speak to a vet if there are any concerns.
As the weather warms, surveillance will remain important. Early reporting can help limit the risk of further spread and protect herds and flocks across Cumbria.
