Bluetongue confirmed in three sheep on County Down farm

In brief: Bluetongue has been confirmed in three sheep on a County Down farm. DAERA says this case brings no additional control zones or movement restrictions, but keepers should check current rules before moving animals.

Bluetongue has been confirmed in County Down after BTV-3 was detected in three sheep, the Department of Agriculture, Environment and Rural Affairs (DAERA) said on 13 November 2026. The department described them as the first cases in Northern Ireland this season.

Bluetongue in County Down: what DAERA confirmed

DAERA Minister Andrew Muir confirmed the detection on a farm in County Down. The virus was found in three sheep. DAERA said the case was not unexpected, given the spread of BTV-3 across Great Britain and Ireland during the current season.

The confirmation is relevant to livestock keepers across Northern Ireland because bluetongue can affect several susceptible species. DAERA lists cattle, sheep, goats, deer, llamas and alpacas among the animals affected.

How bluetongue spreads

Bluetongue is mainly spread by infected biting midges. They are most active between April and November. The virus can replicate inside a midge when temperatures are above 12–15°C, so spread is less likely during winter and early spring.

This seasonal pattern may reduce the chance of transmission in colder months. It does not remove the need for vigilance, particularly while temperatures and midge activity remain suitable for spread.

Is bluetongue a risk to people or food?

No. DAERA says bluetongue poses no threat to public health or food safety. Milk and meat remain safe to consume.

Movement rules and what farmers should do

DAERA says no additional disease control zones or movement restrictions will be introduced in response to this case. BTV-3 was previously confirmed in Northern Ireland in November 2025.

That statement does not mean all livestock movement rules have been lifted. DAERA’s current situation page lists rules that vary by route, including restrictions on some movements from Great Britain. Farmers should check the latest DAERA requirements before moving animals.

Livestock keepers should maintain biosecurity, source animals responsibly and report any suspected disease. Contact your local Divisional Veterinary Office or call the DAERA helpline on 0300 200 7840.
