Avian Influenza Prevention Zone (AIPZ)

An Avian Influenza Prevention Zone (AIPZ) is in place across Great Britain to mitigate the risk of the disease spreading amongst poultry and captive birds.


Avian influenza bio-security requirements

It is a legal requirement for all bird keepers to follow strict biosecurity measures:

  • Keepers with more than 500 birds must restrict access for non-essential people on their sites.
  • Workers need to change clothing and footwear before entering bird enclosures.
  • Site vehicles need to be cleaned and disinfected regularly to limit the risk of the disease spreading.
  • Backyard owners with smaller numbers of poultry including chickens, ducks and geese must also take steps to limit the risk of the disease spreading to their animals.
  • The housing measures legally require all bird keepers to keep their birds indoors and to follow stringent biosecurity measures to help protect their flocks from the disease, regardless of type or size.
  • All bird keepers must keep their birds indoors.
