Researcher takes deeper look into how avian flu spreads

Coughing, sneezing, runny beaks and diarrhea are signs a flock is sick, and avian influenza is likely the cause. When signs are present, producers can have samples from the flock sent to the provincial laboratory for testing to confirm that bird flu is responsible and to determine whether it is a high-pathogenic or low-pathogenic variety.
