After testing positive for bird flu, authorities in Canada said on Tuesday that they have quarantined two poultry farms in British Columbia.
"Preliminary testing by the province of British Columbia has confirmed the presence of H5 avian influenza on two farms in the Fraser Valley" region of the province, said a statement released by the Canadian Food Inspection Agency (CFIA).
The tests were conducted Monday at the two infected sites - a turkey farm and a chicken breeding facility, said officials.
The testing was undertaken after both farms experienced an unexpectedly high number of sudden bird deaths over the weekend.
Officials said infected poultry would be euthanized and discarded in accordance with international health and safety protocols.
