Experts can't explain three avian flu outbreaks in B.C.'s Fraser Valley
Three of four of the most recent avian flu outbreaks in Canada have broken out in British Columbia's Fraser Valley but despite years of trying to figure it out, they still can't explain why the valley attracts the virus.
In the latest outbreak, 60,000 turkeys were culled on an Abbotsford, B.C., farm last week.
Tests so far indicate the virus has not spread to any other poultry producers within a three-kilometre quarantine zone.
