Avian Influenza Outbreaks Return To British Columbia Poultry Flocks

The Fraser Valley is currently experiencing a rise in avian influenza cases as birds begin their autumn migration. Recent data indicates that nine commercial poultry flocks have tested positive for the virus within a two-week window. The initial case of the current season was identified on October 14 in Abbotsford, followed by eight additional confirmations starting last Thursday.

Regional Distribution Of Cases

The affected farms are concentrated in two primary areas. Six of the confirmed outbreaks are located on farms in the Chilliwack region, while the remaining three are situated in Abbotsford. These events are the first new instances of the virus appearing in the province since January of the previous year.

Long Term Effects On Poultry

The avian flu has caused significant losses in British Columbia over the last few years. It is estimated that approximately 8.8 million birds have either died or been culled to prevent the spread of the disease. The timing of the current surge aligns with the seasonal movement of wild birds, which often facilitates the transmission of the virus to domestic flocks.

Legal Battle Over Ostrich Cull

Beyond commercial poultry, an active outbreak remains at an ostrich farm in the southeastern part of the province, which was first detected on December 31. While standard protocols require the culling of affected animals, the owners of the farm have challenged this order. The matter has now reached the Supreme Court of Canada, which is deciding whether to allow an appeal against a lower court’s decision that supported the cull.
