The Chief Veterinary Officers from England, Scotland and Wales have declared an Avian Influenza Prevention Zone (AIPZ) across the whole of Great Britain as of midday on 17th October. This is to try and mitigate the risk of the disease spreading amongst poultry and captive birds following an increase in the number of detections of avian influenza (bird flu) in wild birds and other captive birds. At the moment this just increases the biosecurity levels with no need to house, except for Norfolk, Suffolk and parts of Essex. In these areas an AIPZ is already in place which includes mandatory housing measures for all poultry and captive birds is this zone.
Keepers with more than 500 birds will need to restrict access for non-essential people on their sites. In addition, workers will need to change clothing and footwear before entering bird enclosures and vehicles will need to be cleansed and disinfected regularly. Those 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, this includes ‘backyard owners’. Measures include keeping birds in a fenced area, feed, water and bedding must be stored undercover, and steps taken to prevent access by wild birds. Disinfectant footbaths should be place at strategic entry and exit points to housing.

Schedule 1 of https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1111505/AIPZ_Declaration_17_October_England_excl_Norfolk_Suffolk_pt_Essex.pdf contains the minimum biosecurity measures for all keepers. Those with over 500 birds should also abide with the measures in Schedule 2.
Information for those keepers who reside in Norfolk, Suffolk and parts of Essex and are already in an AIPZ with housing measures can be found at https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1109941/regional-AI-prevention-zone-declaration-housing-measure-suffolk-norfolk-part-essex-08102022.pdf
The introduction of the AIPZ comes after the United Kingdom has faced its largest ever outbreak of avian flu, with more than 190 cases confirmed across the United Kingdom since late October 2021 and over 40 of these confirmed since the beginning of October this year. The East of England has been hit particularly bad, hence the housing requirement of birds in this area.
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. This year, however, the disease has been more prominent in the summer months than previously.
