UFU warns NI farmers as bluetongue cases in GB soar

The Ulster Farmers’ Union (UFU) is warning livestock farmers to remain vigilant following a surge in bluetongue cases across Great Britain, where nearly 500 cases have now been confirmed.

The 2026/27 season commenced on 10 July and, unlike the previous year, when the majority of confirmed cases were asymptomatic and identified through pre-movement testing, most cases this season have been detected after animals presented with clinical signs of the disease. Sheep are currently more likely to be identified showing clinical signs, however it is important to remain vigilant to all susceptible livestock as the situation evolves.

UFU deputy president, Clement Lynch, said, “The unfolding situation in Great Britain is extremely concerning and serves as a stark reminder of the serious threat that bluetongue could pose to the Northern Ireland livestock sector.

“Restrictions are still in place for movement of livestock to Northern Ireland from GB, and if bluetongue cases rise in NI, it would undoubtedly lead to the reinstatement of severe restrictions on movements back to the mainland, result in significant financial losses, and disrupt the agricultural supply chain. Derogations are in place for movement to/from ROI, but we need to remain mindful that an increase in cases or clinical signs could jeopardise this trade. With the first detection of BTV-3 cases in Scotland, UFU are continuing to monitor how the trade situation may evolve.”

To date, nearly 1,000 individual animals have been infected, while more than 2,000 potential cases of bluetongue remain under investigation. Due to a sharp increase in demand, bluetongue vaccine supplies are under significant pressure, and farmers could face delays of up to four weeks in obtaining vaccines.

Mr Lynch continued, “Bluetongue vaccine supplies are under severe pressure in GB, with some manufacturers having no available stock at the moment.

“The UFU strongly urges any farmers considering vaccination to consult their private veterinary practitioner to determine the most appropriate course of action for their farm.”

Clinical signs of bluetongue include a high fever, lameness and inflammation of the mucous membranes of the mouth and nose. Affected animals may develop sores and ulceration, swelling of the head and neck, excessive salivation and nasal discharge. Animals may also appear stiff and be reluctant to move due to swelling around the hooves.

“Farmers must remain vigilant for the signs and symptoms of BTV-3, and any suspected cases should be reported immediately to their private veterinary practitioner. All advice relating to notifiable diseases must be strictly followed,” added the deputy president.

“It is vital that farmers act collectively to protect Northern Ireland’s livestock sector and safeguard our agricultural economy from this significant disease threat currently affecting much of Great Britain.”
