Des Moines, IA (KICD) — The High Pathogenic Avian Influenza that’s making domestic and wild birds sick across the country does not seem to be abating. Another case in a commercial turkey flock in Buena Vista County was confirmed Wednesday.

Iowa Ag Secretary Mike Naig just discussed the problem with KICD Farm News last week.

Standard procedure is to euthanize infected flocks and quarantine surrounding farms to monitor for HPAI.

During the previous outbreak in 2015 it was assumed the virus was being tracked from farm to farm. This time they’re not sure HOW it’s spreading.
