  • The current prevention zone (PZ) in place requires heightened biosecurity measures to be put in place across all poultry and captive bird holdings, regardless of commercial activity.
  • Alongside the PZ requirement, the general licence for holding gatherings where galliforme or anseriforme poultry are present has also been taken out of general use.
  • This was based on the knowledge that outbreaks or cases of highly pathogenic avian influenza had been reported in the UK.
  • However, that situation has now changed and there have been no recent outbreaks of disease, all control zones have been lifted, there have been no reported findings in wild birds for over 6 weeks, the migration of wild waterfowl into the UK has stopped and the situation in Europe has improved in the last month.
  • Therefore it is reasonable to review the risk for such events taking place.
  • The purpose of this assessment is to assess the risk of infection of poultry premises primarily via resident wild waterfowl, but also considering other possible pathways.
