AVIAN INFLUENZA has been confirmed on two Norfolk turkey farms.

On 5 December, Defra said the strain on both sites was highly pathogenic H5N8 and set up a 3km protection and 10km surveillance zone in place around the farms.

One of the units to be confirmed was a turkey rearing farm close to King’s Lynn, while the second is close to Attleborough.

Birds on both farms will be humanely culled to stop the spread of disease.

Last week authorities confirmed H5N8 avian influenza on two linked turkey farms in North Yorkshire.

In light of the spread of avian influenza across the UK, Defra has announced a housing order for all captive birds that comes into force from 14 December.

High levels of biosecurity are also a legal requirement following the imposition of an Avian Influenza Prevention Zone across the UK.
