Defra - Avian Influenza Latest Situation - 2 December 2021



New Avian Influenza guidance issued for vets dealing with wild birds and backyard poultry


New Cases in England

  • Highly pathogenic avian influenza (HPAI) H5N1 has been confirmed in birds at the following premises:
  • sixth premises near Thirsk, Hambleton, North Yorkshire
  • near Tutbury, East Staffordshire, Staffordshire
  • near Leominster, North Herefordshire, Herefordshire
  • A 3km Protection Zone and 10km Surveillance Zone has been put in place around each of the premises.


Northern Ireland

  • No cases of avian influenza have been confirmed to date in Northern Ireland. However, a Temporary Control Zone (TCZ-B) has been declared in Northern Ireland effective from 21:00 on the 30 November 2021, following the confirmation of Avian Influenza H5N1 at a third premises in County Monaghan in the Republic of Ireland. As the location of the premises lies close to the border between County Monaghan and County Armagh, the boundary of the 10km zone extends into Northern Ireland. See the DAERA website for further information.


Keepers can check where disease control zones are located in GB and if they are in zone on the Animal and Plant Health Agency (APHA) interactive map, and in Northern Ireland on DAERA’s interactive map


For further information on these cases and details of the measures that apply in the disease control zones currently in force see:

Bird keepers are reminded that an Avian Influenza Prevention Zone (AIPZ) including housing measures is in force across the UK. See GOV.UK for further information.


High standards of biosecurity must be maintained as good practice for the health of your birds, and that good biosecurity is an essential defence against diseases such as avian influenza and is key to limiting the spread of avian influenza in an outbreak.


Keepers must keep a close watch on their birds for any signs of disease, and seek prompt advice from a vet if they have any concerns. Clinical signs indicative of avian influenza must be reported in England to Defra Rural Services Helpline on 03000 200 301. In Wales, contact 0300 303 8268. In Scotland, contact to the local Field Services Office. Failure to do so is an offence.
