A turkey farm in Norfolk has been placed under a temporary control zone and a surveillance zone, extending 3km and 10km around the farm respectively, following the confirmation of highly pathogenic bird flu on a nearby free range turkey farm. The second farm's birds will be culled, and all remaining poultry at the first farm will also be culled. The UK's avian influenza risk level in wild birds has been raised to 'high', and in poultry with suboptimal biosecurity, to 'medium. However, the risk to public health and food safety is reportedly very low. The government is reminding bird keepers to implement strict biosecurity measures to prevent further outbreaks.
