The England wide AIPZ mandating enhanced biosecurity in all other counties remains in force. The interactive map and declaration will be updated on Saturday to show these changes.
Cases of highly pathogenic avian influenza (bird flu) are increasing in both kept poultry and wild birds across multiple areas of Great Britain.
To prevent further spread of disease, an avian influenza prevention zone (AIPZ) mandating enhanced biosecurity is in force across England. A similar zone is in force in Scotland and Wales.
In addition, mandatory housing measures for all kept birds are in force in the East Riding of Yorkshire, City of Kingston upon Hull, Lincolnshire, Norfolk and Suffolk and the unitary authorities of Shropshire, York and North Yorkshire. From 00:01 on Sunday 16 February 2025 these mandatory housing measures will be extended to also include Herefordshire, Worcestershire, Cheshire, Merseyside and Lancashire.
To find out which measures apply to you and your kept birds, check the interactive map and read the AIPZ declaration schedule relevant to your area.
These measures will be in place until further notice. They will be kept under regular review as part of the government’s work to monitor and manage the risks of avian influenza.
These measures apply to all bird keepers whether you have pet birds, commercial flocks or just a few birds in your garden and are essential to protect your birds from avian influenza.
