Avian influenza outbreak prompts prevention zone
© Tim Scrivener A fourth case of avian influenza has been confirmed in Norfolk, escalating concerns as the UK prepares for the Christmas season.
The latest case of highly pathogenic avian influenza (HPAI) H5N1 was detected at a premises near Cranworth, south of Dereham.
All birds at the site will be humanely culled, and a 3km protection zone has been implemented to limit further spread.

This marks the fourth case in Norfolk this month, following previous outbreaks in Watton and Dereham.
Defra has swiftly enacted an avian influenza prevention zone (AIPZ) across Norfolk, Suffolk, Lincolnshire, and parts of Yorkshire.
Effective from 13 December, the AIPZ mandates strict biosecurity measures for all bird keepers in the affected areas.
These include the prevention of contamination from wild birds, thorough cleaning of equipment, and separation of captive birds from external risks.
Although housing of birds is not currently required unless within a designated 3km protection zone, Defra warns this measure is under constant review.
Since November 2024, when the first case of HPAI H5N1 was confirmed, the disease has significantly impacted the UK poultry sector.
Six cases of H5N1 and one of H5N5 have been confirmed in England this season.
Neighbouring regions, including Wales, Scotland, and Northern Ireland, have not reported any cases this winter.
‘Stay vigilant’
UK chief vet Christine Middlemiss said: “Bird keepers must exercise robust biosecurity measures, remain alert for any signs of disease and report suspected disease immediately to the Animal and Plant Health Agency.”
Defra has also launched informational webinars to assist commercial and backyard bird keepers in managing risks effectively.
The public health risk remains low, and properly cooked poultry and eggs continue to be safe for consumption, according to the UK Health Security Agency and the Food Standards Agency.
