Highly-pathogenic avian influenza has sickened four poultry-farm workers in Washington State and broken out in five poultry farms in British Columbia.
The commercial poultry farms were three located in Chilliwack and two in Abbotsford.
The flocks will be destroyed and quarantine zones have been set up by the Canadian Food Inspection Agency.
The Washington State workers are at an egg farm in Franklin County; the flock was euthanized after an outbreak Oct. 15.
