More Idaho Dairy Cattle Hit With H5N1 Avian Flu

Jun 22, 2026

By Stephanie Soucheray

Recent updates from the US Department of Agriculture Animal and Plant Health Inspection Service (APHIS) show a spike of H5N1 avian flu activity in Idaho dairy cattle, with 33 cattle affected on dairy milking facilities in the past 30 days. Utah also reported three H5N1 detections among cattle this month.

So far this year, APHIS has tracked 54 H5N1 cases among cattle, far fewer than the 917 reported in 2024. Last year, 171 cattle were sickened with avian flu.

In bird news, another live-bird market, this one in Providence, Rhode Island, reported avian flu in 450 birds. The detection comes one week after a bird market in Passaic, New Jersey, reported 670 sick animals.
