The UK government has confirmed two cases of the highly pathogenic avian influenza (H5N1) virus on commercial turkey farms in Norfolk, prompting the declaration of protection and surveillance zones. All poultry on the affected farms will be culled. This follows the establishment of an 'AIPZ' restriction zone in East Yorkshire, Lincolnshire, Norfolk, and Suffolk, aimed at limiting the spread of the disease. This zone mandates strict biosecurity measures for bird keepers, including cleansing and disinfection of equipment and clothing, reduction of movement, vermin control, and regular disinfection of housing. The UK Health Security Agency reiterates that the risk to public health is low.
