Avian influenza (bird flu)

Avian influenza is a highly infectious disease affecting many species of birds, including poultry, wild and pet birds.


The Avian Influenza Prevention Zone (AIPZ) for poultry and captive birds, introduced to help stop the spread of avian influenza (bird flu), has been lifted. The enhanced biosecurity measures were brought in across Great Britain in October when there was a medium risk for some poultry premises. The measures have been vital in protecting flocks across the country from virus which is circulating in wild birds.

The UK has self-declared zonal freedom from highly pathogenic avian influenza for Great Britain with effect from 29 March 2024. This is in line with World Organisation for Animal Health (WOAH) rules.

From 26 April 2023, gathering of all poultry and other captive birds including ducks, gees and swans are permitted. You will need to follow the requirements of the poultry gathering general licence and notify the Animal and Plant Health Agency (APHA) at least 7 days before the event.

The signs of avian influenza and details of where to report suspected cases in poultry or other captive birds are on the DEFRA website.

Wild birds

You can report dead sick or injured wild birds or get advice on what to do with dead wild birds that are not collected for testing.

Register your flock

You can help prevent the spread of disease and protect the national poultry flock by registering your flock (however small) on the Poultry Register.
