A recent affidavit from Canada’s deputy chief veterinarian has revealed that ostriches at a British Columbia farm facing a cull order were affected by a particularly dangerous strain of avian influenza virus. Dr. Cathy Furness of the Canadian Food Inspection Agency stated that further testing showed a unique and highly lethal form of the virus in the birds, with enhanced pathogenicity that even proved fatal to mice in low doses.
The affidavit expressed concerns over the unknown status of the infection in the ostriches at the Edgewood farm, raising questions about the potential risks to animal and human health. The CFIA is currently in legal proceedings to enforce the cull of approximately 400 ostriches, despite claims from the farm owners that the flock has developed immunity since the initial outbreak that resulted in the death of 69 birds.
Furness emphasized the urgency of the situation, highlighting the ongoing health risks associated with delayed action and the need for decontamination measures. The affidavit pointed out the challenges in accurately assessing the infection status and risks of reinfection due to gaps in scientific knowledge about avian influenza in ostriches.
The filing also addressed the farm owners’ non-compliance with quarantine regulations, which further complicates the containment of the virus. Avian influenza viruses have the potential to persist in the environment for extended periods, posing a continued threat of reinfection even after infected birds have recovered.
Universal Ostrich Farms continues to argue for the preservation of the birds, citing their scientific value and minimal threat posed. Legal battles have ensued, with the farm seeking stays and pursuing hearings in higher courts to prevent the culling of the ostriches.
