Midwest States Face Major Outbreak Of Avian Flu

MADISON, WISCONSIN - MARCH 24: Microbiologist Anne Vandenburg-Carroll tests poultry samples collected from a farm located in a control area for the presence of avian influenza, or bird flu, at the Wisconsin Veterinary Diagnostic Laboratory at the University of Wisconsin-Madison on March 24, 2022 in Madison, Wisconsin. The presence of avian influenza was recently discovered on a commercial egg farm near Palmyra, Wisconsin, forcing the farm to dispose of nearly 3 million chickens. To control the spread of the virus, the U.S. Department of Agriculture has mandated testing of all poultry in a control area established around the infected farm before it can be sold or transported.
