NFU Scotland is urging all poultry keepers to assess their biosecurity measures after a new outbreak of highly pathogenic avian influenza (AI) in a commercial free-range flock in Yorkshire.

The H5N5 (HPAI H5N5) strain of AI had only been detected in wild birds previously, the flock in Yorkshire marking its transition to domesticated birds, raising serious concerns.

The outbreak zone near Hornsea in East Riding has been implemented with a 3km protection zone and a further 10km surveillance zone to contain the spread of the strain.

Authorities have confirmed that all poultry from the site have been humanely culled as they try to stop the spread of the first case of bird flu to be detected in the country since February 14, 2024.

NFUS have reminded flock keepers to adhere to the new requirements for poultry and register their birds’ details with the Scottish Kept Birds Register by December 1.

The public should remain vigilant regarding the ongoing situation. If sick or deceased wild birds are discovered, they should avoid touching them, keep pets away, and immediately contact Defra's national helpline at 03459 33 55 77 (option 7).

NFU Scotland’s Poultry Committee chair, Robert Thompson said: “In the expectation that Avian Influenza will once again impact on Scottish poultry flocks this winter, reviewing your biosecurity measures now is the sensible step to take to best protect Scottish poultry.

“Since the UK was declared an AI-free zone earlier this year, it is possible that some farms may have taken their eye off the ball. This new case means everyone needs to up their game. AI will find the weak point in any biosecurity, as this is a virus that knows no boundaries.

“Every poultry keeper, whether you have one hen in the back garden or a large poultry business, must consider biosecurity measures seriously and take steps to protect your birds from this devastating disease.

“In terms of assisting Scotland’s response were an AI outbreak to occur, it is in everyone’s interest that every poultry flock, large or small, is included on the new Scottish Kept Bird Register. The deadline for compliance is 1 December 2024

“Scottish and GB poultry keepers have had to live with the heightened threat of AI at this time of year for several years now, linked to wild and migratory birds. Many will have already prepared for this eventuality and it’s crucial that everyone, including the public, remains vigilant and reports any signs of disease in birds at the earliest opportunity.”

The UK Health Security Agency (UKHSA) has stated that bird flu is primarily a disease affecting birds and poses little risk to human health.

In addition to this, the Food Standards Agency (FSA) has also confirmed that bird flu presents a very low food safety risk for UK consumers, assuring people that properly cooked poultry and poultry products, including eggs, are safe for consumption.
