A sudden spike in avian influenza cases in British Columbia in the past week has now spread to seven farms and affected thousands of birds, according to the Canadian Food Inspection Agency.

Some 155,000 birds have either died or will be euthanized, the Associated Press reports.

The outbreak originated in the Fraser Valley near Vancouver last week, where turkeys and chickens from two farms tested positive for the H5N2 strain of the virus.

Although the bug does not pose a major threat to humans as long as the meat from these birds is cooked properly, its sudden resurgence a huge blow to the region’s poultry industry.
