Seven countries have imposed trade restrictions on Canadian poultry as a fifth farm in British Columbia (B.C.) was put under quarantine for avian influenza, according to Fox Business.

More than 140,000 turkeys and chickens from the affected farms will be euthanized.

Avian influenza was first detected a week ago on a broiler-breeder chicken farm in Chilliwack.

The B.C. outbreak has the United States, Japan, South Korea, Taiwan, China, South Africa and Mexico issuing a ban on poultry products from B.C. or all of Canada.
