Avian Influenza incursion risk raised to medium ahead of winter migration season

Wild birds migrating westward from mainland Europe during the winter period can spread the disease to poultry and other captive birds. However, the UK has robust biosecurity measures and monitoring in place to prevent the disease spreading in this country and the risk of transmission of avian influenza viruses to the general public in Europe remains very low.

A statement from the UK’s four Chief Veterinary Officers said:

Following two confirmed cases of H5N8 avian influenza in the Netherlands we have raised the risk level for incursion to the UK from migratory birds to medium ahead of the winter migration season. The risk of the disease being introduced to poultry farms in the UK remains low.

We are monitoring the situation carefully and bird keepers should remain alert for any signs of disease, report suspected disease immediately and ensure they are maintaining good biosecurity on their premises.

There are some simple measures that all poultry keepers, whether they are running a large commercial farm, keeping a few hens in their back garden, or rearing game birds, should take to protect their birds against the threat of avian flu in the coming winter months.

These include:

  • Keeping the area where birds live clean and tidy, controlling rats and mice and regularly cleansing and disinfecting any hard surfaces
  • Cleaning footwear before and after visits
  • Placing birds’ feed and water in fully enclosed areas that are protected from wild birds, and removing any spilled feed regularly
  • Putting fencing around outdoor areas where birds are allowed and limiting their access to ponds or areas visited by wild waterfowl
  • Where possible, avoid keeping ducks and geese with other poultry species.

This strain of the disease can be very virulent in birds. There are no recorded cases worldwide where it has caused disease in humans.

The UK was previously declared free of avian flu in September 2017 and has remained free of highly pathogenic avian influenza since then. However, a low pathogenic H5N3 strain of the disease, which poses no threat to human health, returned in December 2019 and was quickly dealt with by Government action. The UK declared itself free from avian influenza in June 2020.

The Government continues to monitor for incursions of avian flu and is working with the poultry and game bird industries; hen rehoming and pure and traditional poultry breeds stakeholders to help reduce the risk of disease.
