Suspected Bluetongue case under investigation in NI as 20km control zone imposed

DAERA vets are investigating a suspected case of Bluetongue virus at a livestock holding near Bangor, Co Down, prompting urgent disease control measures and the introduction of a 20km Temporary Control Zone (TCZ).

The Department of Agriculture, Environment and Rural Affairs (DAERA) confirmed that results from its active Bluetongue surveillance programme “indicated the presence of the disease in two cows”.

Officials have now implemented what they describe as “robust disease control measures” while further investigations take place.

The TCZ came into effect at 21:00 on 29 November 2025, restricting all movements of susceptible species — including cattle, sheep, goats, deer, llamas and alpacas — on or off premises within the zone.

Movements directly to slaughter remain permitted under a general licence available via the DAERA website.

Minister urges compliance amid ‘great concern’

DAERA Minister Andrew Muir said the suspected cases were “of great concern” but stressed the importance of full industry cooperation.

He said:

“While there was always a potential for Bluetongue to arrive here, given its prevalence in GB and the EU, we must now do all we can to protect our livestock and limit the spread of the disease.

“That is why, as a result of the Disease Control Framework for the virus we launched in June, DAERA has moved rapidly to ensure disease control measures are put in place. Members of the public should be reassured the virus does not have any impact on people or food safety.

“In the face of these suspected cases, my officials are taking all the necessary steps to protect the agri-food industry. I urge everyone in the industry to play their part as well and especially appeal to those in the Temporary Control Zone to follow the restrictions.

“My department is working closely with all stakeholders, including colleagues in GB and the Republic of Ireland, to monitor the situation.”

Bluetongue is primarily spread through the bites of infected midges, which are most active from April to November. While the virus poses no risk to human health or food safety, it can be devastating for infected livestock and can disrupt trade.

Chief Vet warns of rapid spread

Chief Veterinary Officer Brian Dooher warned that the disease is “unpredictable” and can spread swiftly.

He said:

“Bluetongue virus is unpredictable and can spread rapidly through and between flocks and herds. Colleagues have been preparing for a possible incursion of this disease and have been working closely with our colleagues in the Republic of Ireland to ensure a co-ordinated response in tackling any incursion.

“I would urge all farmers to ensure they source their animals responsibly. The spread of Bluetongue could have a significant impact on livestock and the rural economy.

“Furthermore, all livestock owners should remain vigilant for signs of the disease. It is imperative that keepers report any symptoms immediately to their vet, local Divisional Veterinary Office or to the DAERA helpline on 0300 200 7840.”

Background: What is Bluetongue?

Bluetongue affects cattle, sheep, goats, deer and camelids such as llamas and alpacas. Transmission is heavily influenced by climatic conditions and wind patterns, with colder temperatures significantly reducing the risk of spread.

Northern Ireland’s agricultural sector has been preparing for a potential incursion due to the virus’s prevalence in Great Britain and parts of Europe.

DAERA continues to monitor the situation closely alongside authorities in the Republic of Ireland.
