  • United Kingdom - Low Pathogenic H5N3 bird flu confirmed in commercial poultry flock

    Wednesday 11 December 2019 Chief Veterinary Officer Dr Robert Huey has urged local poultry farmers to maintain good biosecurity following the confirmation that Low Pathogenic Avian Influenza (LPAI) of the H5 strain has been found in mid Suffolk.

    The strain was found in a flock of broiler breeder chickens at a commercial farm.

    Dr Huey commented: “In Northern Ireland the risk to poultry remains low, however Avian flu is a constant threat to all poultry. In the winter months there is always an increasing risk of disease incursion from migrating birds and were it to enter our Northern Ireland flock, it would have a significant impact on our poultry industry, international trade and the wider economy.

    “All poultry keepers, including those keeping game birds and pet birds need to act now and maintain good biosecurity at all times in order to reduce the risk of transmission of avian flu to their flocks.

    Avian influenza (bird flu) identified in Suffolk

    Published 10 December 2019


    Low pathogenic avian flu of the H5 strain has been confirmed at a commercial chicken farm in Mid Suffolk, on Tuesday 10 December 2019.


    All the birds will now be humanely culled and we have put in place a 1km restriction zone around the infected farm to limit the risk of the disease spreading.

    The advice from Public Health England (PHE) is that the risk to public health from the virus is very low and the Food Standards Agency has made clear that bird flu does not pose a food safety risk for UK consumers. Thoroughly cooked poultry and poultry products, including eggs, are safe to eat.
