Minister for Agriculture Martin Heydon has announced new biosecurity regulations that will require all poultry and captive bird keepers to introduce stricter disease control measures from 1 November 2025.

The move comes amid concern over the spread of Highly Pathogenic Avian Influenza, following recent detections in wild birds and confirmed outbreaks in flocks in Co Tyrone and Co Cork.

The department has confirmed that 41 wild birds have tested positive for the virus so far this year. The risk typically increases during the winter migration of wild waterfowl, which are the natural carriers of avian influenza.

Speaking on Friday, Mr Heydon said the situation highlighted a growing threat to Irish poultry producers.

“There is a significant risk to Irish poultry and captive bird flocks, which is increasing as winter approaches,” he said. “Strict and consistent biosecurity is the most effective mechanism to reduce the risk of transmission.”

Under the new rules, all flock keepers, including those with small backyard flocks, will be required to follow specific biosecurity measures aimed at preventing contact between domestic birds and wild birds. Larger flocks of 350 birds or more will be subject to enhanced requirements.

The department is urging flock owners to watch closely for signs of disease and to report any concerns immediately to their local Regional Veterinary Office or, outside business hours, through the National Disease Emergency Hotline on 01 492 8026.

Members of the public are being advised not to handle sick or dead wild birds. Dead birds should instead be reported through the AvianCheck app.

The department said it continues to monitor the situation and remains in regular contact with poultry industry representatives.

In Northern Ireland, Agriculture Minister Andrew Muir has confirmed that an Avian Influenza Prevention Zone will be introduced from the same date. The zone places a legal requirement on all bird keepers to follow strict biosecurity measures, regardless of flock size or whether birds are kept commercially or as pets.

Mr Muir said the onset of winter migration increases the risk of infection and warned that an outbreak could have severe consequences for producers and the wider agri-food sector.

Chief Veterinary Officer Brian Dooher said the measures include ensuring that food and water are inaccessible to wild birds and that cleansing and disinfection are carried out thoroughly. There is currently no requirement to house birds and gatherings are not prohibited, although this remains under review.

Bird keepers in Northern Ireland are being encouraged to register their flocks and sign up for text alerts.
