Avian flu

The UK chief veterinary officers lifted the housing requirement of the Avian Influenza Prevention Zone (AIPZ) on Monday 2 May 2022. Other requirements remain in place.

It is a legal requirement for all bird keepers across the UK to follow strict biosecurity measures in order to limit the spread of and eradicate the disease.

An AIPZ was originally put in place across the whole of England at 5pm on Wednesday 3 November following a number of confirmed cases among wild and commercial birds, This was extended to include housing measures across the UK on the 29 November 2021.

Avian influenza circulates naturally in wild birds and when they migrate to the UK from mainland Europe over the winter they can spread the disease to poultry and other captive birds.

The UK health agencies advise that the risk to public health from the virus is very low and the UK food standards agencies advise that avian influenzas pose a very low food safety risk for UK consumers. Properly cooked poultry and poultry products, including eggs, are safe to eat.

The national AIPZ means that bird keepers all across the country must:

  • Cleanse and disinfect clothing, footwear, equipment and vehicles before and after contact with poultry and captive birds - if practical, use disposable protective clothing
  • Reduce the movement of people, vehicles or equipment to and from areas where poultry and captive birds are kept, to minimise contamination from manure, slurry and other products, and use effective vermin control
  • Thoroughly cleanse and disinfect housing on a continuous basis
  • Keep fresh disinfectant at the right concentration at all farm and poultry housing entry and exit points
  • Minimise direct and indirect contact between poultry and captive birds and wild birds, including making sure all feed and water is not accessible to wild birds

Bird keepers should visit the avian flu guidance on gov.uk for full details of the AIPZ and updated biosecurity guidance.
