Authorities in Northern Ireland are urgently investigating the first suspected outbreak of the bluetongue virus within its borders, a development with serious implications for the local farming industry.
Control Zone Established After Suspected Cases
The disease is believed to be affecting two cows on a farm near Bangor, County Down. In a swift response, the Department of Agriculture, Environment and Rural Affairs (Daera) established a 20km temporary control zone (TCZ) on Saturday, 29 November 2025.
Movement of all susceptible animals, including cattle, sheep, goats, deer, and llamas, in or out of this zone is now prohibited. A general licence has been issued, permitting animals to cross the boundary only if they are being transported directly to slaughter.
Understanding the Bluetongue Threat
Bluetongue is a non-contagious animal disease that is primarily spread by biting midges. It poses no risk to human health or food safety. Symptoms in livestock can include:
- A blue and swollen tongue
- Fever
- Significantly reduced milk yield
- In the most severe instances, death
The suspected cases were identified through Daera's active surveillance programme, designed to catch such incursions early.
Official Response and Industry Warnings
Agriculture Minister Andrew Muir stated that the government had anticipated the potential arrival of the virus, given its presence in Great Britain and the EU. He emphasised that Daera had moved rapidly to implement disease control measures based on a framework launched in June.
"I urge everyone in the industry to play their part," Minister Muir said, "and especially appeal to those in the temporary control zone to follow the restrictions."
Brian Dooher, Daera's Chief Veterinary Officer, warned that the virus is unpredictable and can spread rapidly. He urged all farmers to remain vigilant for symptoms and to report them immediately to a vet or the Daera helpline on 0300 200 7840.
The news has also caused concern south of the border. Irish Agriculture Minister Martin Heydon called it "unwelcome" and expressed solidarity with the affected farm family. He noted the serious implications for the entire island, as an established outbreak could lead to widespread animal health issues and financial strain for farmers.
Broker Context and Movement Bans
This suspected incursion follows the confirmation of the first case of bluetongue serotype 3 (BTV-3) in England in a sheep in Norfolk on 26 August 2024. Daera reports that there are now over 260 premises affected in England.
As a direct consequence, the movement of all ruminants and camelids from Great Britain to Northern Ireland is currently suspended. This ban will remain in place until the UK regains its EU-recognised disease-free status for bluetongue.
