Fifth Iowa outbreak of bird flu confirmed in a backyard Warren County flock

Iowa confirmed another incident of bird flu, this time in Warren County, marking the fifth outbreak found in the state since the start of the month.

The most recent outbreak was found at a non-commercial, backyard mixed flock of about 50 birds, the Iowa Department of Agriculture said Sunday.

"No cases of bird flu affecting humans have been detected in the United States," Chloe Carson, spokesperson for the agriculture department, said. "It is not a human health risk and poultry products remain safe to eat."

Gov. Kim Reynolds signed a disaster proclamation for Buena Vista County, which had outbreaks confirmed among commercial operations on March 6 and 17.
