Suspect case of notifiable Avian Flu found in commercial poultry premises, Co Tyrone

​

Date published: 5 October 2025

Disease control measures have been initiated by the Department of Agriculture, Environment and Rural Affairs (DAERA) following a suspect case of notifiable highly pathogenic avian influenza (HPAI) at a commercial poultry premises near Omagh.


The Chief Veterinary Officer (CVO) for Northern Ireland, Brian Dooher has taken the decision based on number of factors including the clinical signs and preliminary results provided by the Agri-Food and Biosciences Institute (AFBI).

Minister of Agriculture, Environment and Rural Affairs, Andrew Muir confirmed:

“A suspect case of notifiable Avian Influenza was reported on Friday 03 October and initial results suggest the presence of notifiable HPAI. The CVO has, therefore, taken the decision, as a precautionary measure, to apply appropriate disease control measures, including the humane culling of all poultry on the site and the introduction of Temporary Control Zones (TCZ) to mitigate for onward disease spread.

“This suspect incursion of HPAI is a stark reminder that we cannot afford to be complacent. It is imperative that all bird owners – from backyard hobbyists to commercial flock keepers with thousands of birds – adhere to all biosecurity measures to protect their flocks.”​

Chief Veterinary Officer (CVO), Brian Dooher added:

“The disease control measures are crucial to limit any potential spread of disease and I appeal to all bird owners – backyard and commercial – to take all necessary steps to protect your flock. This includes ensuring continuous excellent levels of biosecurity and reporting any suspect cases of avian flu to DAERA immediately.

“Samples from the infected premises have been sent to the National Reference Laboratory to confirm strain and pathogenicity. Should HPAI be officially confirmed, these TCZs will be revoked and replaced with a 3 kilometre Protection Zone (PZ) and 10 kilometre Surveillance Zone (SZ).”​

Full details of the scope and measures required within the TCZs have been published on the DAERA website.

Members of the public are encouraged to report dead waterfowl (swans, geese or ducks) or gulls, or five or more dead wild birds of other species in the same location, via the DAERA Dead Wild Bird Online Reporting Tool

Bird flu confirmed in Suffolk as England records ninth case of the season

​

Defra has confirmed a new outbreak of highly pathogenic avian influenza (HPAI) H5N1 at a large commercial poultry unit near Brandon, West Suffolk – the latest in a growing number of cases across England this season.

A 3km protection zone and a wider 10km surveillance zone have been declared around the affected premises, where all birds will be humanely culled to prevent the spread of infection.

This marks the ninth confirmed case in England since the start of the 2025–26 outbreak season, bringing the UK total to 11 cases. Wales and Northern Ireland have each reported one case so far this season, while Scotland remains free of detections.

From Thursday 30 October, new mandatory housing measures came into force in parts of England as part of the ongoing avian influenza prevention zone (AIPZ).

Keepers in 20 high-risk counties, including Norfolk, Suffolk, Lincolnshire, Lancashire and Yorkshire, are now required to house their birds.

The government continues to urge bird keepers to remain vigilant for signs of bird flu and to report suspected cases immediately. Enhanced biosecurity remains mandatory across the country under the current AIPZ.

The UK officially lost its status as free from highly pathogenic avian influenza earlier this month under World Organisation for Animal Health (WOAH) rules, following the first confirmed case in England on 11 October 2025.
