[TD]One additional farm with clinical signs has been confirmed as infected with the H5N2 highly pathogenic avian influenza virus (ONT-2015-NAI-003). On 22 April 2015, the Canadian Food Inspection Agency (CFIA) announced the establishment of a second Avian Influenza Control Zone (AICZ) in Ontario to control the movement of poultry, poultry products and equipment in contact with poultry in the area to minimize disease spread. The boundary of this second AICZ covers a 10km radius from the ONT-2015-NAI-002 premises confirmed to be infected with avian influenza. The zone spans across a portion of Oxford County and Waterloo County, Ontario. Infected premises ONT-2015-NAI-003 is located in Oxford County within the second AICZ. All premises located within the AICZ have been placed under quarantine. The CFIA is monitoring these premises closely for any signs of disease. Humane depopulation of all susceptible animals was completed on infected premises ONT-2015-NAI-002 on 20 April 2015 and on infected premises ONT-2015-NAI-003 on 26 April 2015. The process for disposal in all barns has started. All activities on farm are under the direct supervision of the CFIA.[/TD]
