The avian flu, specifically the H5N1 or H5-HPAI strain, has been detected in the Fraser Valley wetlands, from Delta to Chilliwack, including Langley. It was first identified in October at various locations such as Mill Lake in Abbotsford, West Creek Wetlands in Langley, and Roberts Bank Foreshore and the Reifel Bird Sanctuary in Delta. The Canadian Food Inspection Agency later confirmed the virus in three commercial poultry farms in the area. In response, B.C.'s chief veterinarian, Dr. Theresa Burns, issued a general order prohibiting the commingling of poultry in the Lower Mainland to prevent the spread of the virus. The order, which includes a list of places where birds cannot be taken, is in effect until it is rescinded.
