Bird keepers across North Wales are being urged to strengthen their biosecurity measures ahead of the winter period, when the risk of avian influenza is expected to increase.

The warning applies to everyone who keeps birds, from households with a few hens or pet birds to commercial poultry farms, with Welsh Government officials stressing that preparations should begin now rather than waiting for the risk to rise.

Keepers are being encouraged to review their hygiene arrangements, complete a biosecurity self-assessment checklist and make sure protective measures are part of their daily routine.

The advice includes keeping bird housing and surrounding areas clean, restricting unnecessary visitors and preventing contact between domestic birds and wild birds, which can spread the disease.

The Chief Veterinary Officer for Wales, Dr Richard Irvine, said strict biosecurity remained the most effective way to protect birds from avian influenza.

He said: “Don't wait until the risk increases – the time to act is now.”

Dr Irvine added that simple, consistent precautions could help prevent infection from entering flocks, thanking keepers across Wales for remaining vigilant and reporting suspected cases promptly.

Signs of avian influenza can include a swollen head, blue discolouration of the neck and throat, loss of appetite, breathing difficulties, diarrhoea, a drop in egg production and an increase in bird deaths.

Anyone who suspects the disease in their flock must contact the Animal and Plant Health Agency immediately on 0300 303 8268.

Biosecurity self-assessment checklists are available to help bird keepers identify weaknesses in their arrangements and take action to address them before the higher-risk winter period.

The warning is intended to ensure that both domestic and commercial bird keepers across North Wales and the rest of Wales are prepared to reduce the risk of infection spreading among their birds.
