All-Wales Avian Influenza Prevention Zone

Following a number of detections of avian influenza (bird flu) in wild birds across Great Britain, the Chief Veterinary Officers from Wales, England and Scotland have declared an Avian Influenza Prevention Zone (AIPZ) across the whole of Great Britain to mitigate the risk of the disease spreading amongst poultry and captive birds.

Bird keepers must adhere to certain biosecurity measures, as set out in the declaration. As of 29 November 2021, the declaration is extended. It will become a legal requirement for all poultry and captive bird keepers to house their birds, or keep them separated from wild birds.

Find out more about the All-Wales Avian Influenza Prevention Zone on the Welsh Government website.
