The case was identified following active surveillance by the Department for Agriculture, Environment and Rural Affairs (DAERA) and has been tracked to a holding close to Bangor.
A 20km temporary control zone (TCZ) has been introduced and has been in operation since 9pm on Saturday evening after two cows tested positive for the disease.
First identified in the Netherlands in September 2023, Bluetongue disease is a virus spread among livestock mainly by biting midges. It affects sheep, cattle, other ruminants such as deer and goats and camelids such as llamas and alpacas.
Symptoms include fever, lameness, swelling of the face and ulcers or redness around the mouth, nose and eyes of an animal.

The virus does not pose any threat to people or to food safety, but outbreaks can result in prolonged restrictions on animal movement and trade.
The Department said the virus could have a “devastating impact on animals infected”.
NI’s TCZ prohibits the movement of susceptible species on or off premises within the zone while officials carry out further investigations. Moves direct to slaughter are permitted under a general licence available on the DAERA website.

Minister Andrew Muir said that while the suspected case was of great concern, it was essential all producers impacted by control measures adhered to them.
“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,” he said.
“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.”
Chief Veterinary Officer, Brian Dooher 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.”
