Defra - Avian Influenza Latest Situation

11 November 2025

Due to a significant increase of findings of avian influenza in kept and wild birds, housing measures to protect poultry & captive birds from #AvianInfluenza will come into force in Wales from Thursday 13 November. This means that from this time it will be a legal requirement for all keepers in Wales with 50 or more birds and all keepers who sell or give away eggs, meat or poultry (even if they keep fewer than 50 birds), to house their birds.

Keeping your birds undercover away from wild birds is vital to minimise the risk of them becoming infected with avian influenza by wild birds.

The new compulsory housing measures will be incorporated into the existing Wales Avian Influenza Prevention Zone (AIPZ) introduced in January. Please see GOV.WALES for further info: https://www.gov.wales/compulsory-housing-measures....

Additional biosecurity requirements will also be introduced for the gamebird sector, which experienced avian influenza outbreaks last season.

An AIPZ with mandatory housing measures is in force in England and an AIPZ requiring mandatory biosecurity measures remains in place across GB: https://www.gov.uk/.../bird-flu-regional-avian-influenza....
