The first Nova Scotia case was in a backyard flock. CFIA said then that farmers ought to take biosecurity precautions, indicating that the disease is likely coming from wild birds.
The disease is deadly to poultry and highly contagious. Flocks that are infected are destroyed and the CFIA establishes a quarantine zone forbidding any traffic in or out.
