Cases of highly pathogenic bird flu detected in Delaware and Michigan

Delaware and Michigan are the latest states to report cases of the highly pathogenic avian influenza, the U.S. Department of Agriculture confirmed. The virus, also known as the bird flu, does not pose an immediate threat to the public, according to the Centers for Disease Control and Prevention. 

Cases were confirmed in a commercial poultry flock in New Castle County, Delaware, and in a non-commercial backyard flock in Kalamazoo County, Michigan. Officials in both states have quarantined the affected premises. The birds will be "depopulated" in order to prevent the disease from spreading, and they will not enter the food system, the USDA said. 

The department's inspection service is working with Delaware and Michigan animal health officials.
