On 16 November the Chief Veterinary Officer for the UK confirmed an outbreak of highly pathogenic avian influenza on a duck breeding farm in East Yorkshire.    The Office of the UK’s Chief Veterinary Officer restricted the premises when the case was first reported to them on the 14 November and a restriction zone has been put in place around the farm, which bans all unlicensed movements of all poultry and poultry products in the zone.  The 6000 ducks on the farm are being humanely destroyed today. The Animal and Plant Health Agency laboratory in Weybridge has confirmed today that the exact strain of the disease is H5N8 and investigations are ongoing to determine the source of the outbreak and whether it is linked to the outbreaks in the Netherlands and Germany.
