AIPZ housing measures to be lifted
Bird keepers are warned that birds may take time to reacclimatise.
The chief veterinary officer (CVO) has confirmed that mandatory housing measures are to be lifted in Avian Influenza Prevention Zones (AIPZs) in the UK.
From Thursday, 15 May 2025, poultry and captive birds will no longer need to be housed and can be kept outside.
Defra advises that bird keepers prepare ranges and outside areas before releasing their birds, as they may still be contaminated. This includes disinfecting hard surfaces, fencing off ponds and reintroducing wild bird deterrents.
Bird keepers are warned that birds may take time to reacclimatise, and so should be gradually released over a period of days.
The government maintains that strict biosecurity is the best way to prevent the spread of avian influenza. It says that birdkeepers in AIPZ are still legally required to follow the highest biosecurity measures, such as thorough disinfecting clothes and equipment.
The housing measures will remain in place for bird keepers in a Protection Zone or a Captive Bird Monitoring (Controlled) Zone, where there may have been recent outbreaks of avian influenza. Bird gatherings also remain banned.
Defra says that the decision was made as a result of a risk assessment, supported by scientific evidence, which found that the risk of avian influenza levels in wild birds and poultry had reduced.
Christine Middlemiss, UK CVO, said: "Following a sustained period of reduced risk from avian influenza, we are now able to lift the mandatory housing measures in effect in various counties, which is testament to the hard work and vigilance of bird keepers across the country who have all played their part in managing the spread of this disease.
“While the lifting of mandatory housing measures will be welcomed by bird keepers, it is imperative that keepers continue to practice stringent biosecurity and that any suspicions of disease are reported to the Animal and Plant Health agency immediately."
