Canada's Food Inspection Agency ordered the cull of the Universal Ostrich Farms flock after two birds tested positive for H5N1 avian flu, following standard protocol to eradicate highly pathogenic strains that have wiped out millions of poultry globally and pose zoonotic risks. The entire exposed group must be depopulated to prevent potential spread or mutation, even if currently healthy, as partial measures risk outbreaks. US relocation offers were rejected to enforce biosecurity laws, prioritizing containment over exceptions despite the controversy.
