The Agriculture Department’s Animal and Plant Health Inspection Service today confirmed the presence of highly pathogenic avian influenza (HPAI) in a commercial poultry flock in New Castle County, Delaware.

Samples from the flock were tested at the University of Delaware’s Allen Laboratory in Newark, part of the National Animal Health Laboratory Network, and confirmed at the APHIS National Veterinary Services Laboratories (NVSL) in Ames, Iowa. APHIS is working closely with state animal health officials in Delaware on a joint incident response. State officials quarantined the affected premises, and birds on the property will be depopulated to prevent the spread of the disease. Birds from the flock will not enter the food system.

Avian influenza has already been detected in several other states.

According to the U.S. Centers for Disease Control and Prevention, the recent HPAI detections do not present an immediate public health concern. No human cases of these avian influenza viruses have been detected in the United States. As a reminder, the proper handling and cooking of poultry and eggs to an internal temperature of 165 degrees F kills bacteria and viruses.

APHIS said, “USDA will report these findings to the World Organisation for Animal Health (OIE) as well as international trading partners. USDA also continues to communicate with trading partners to encourage adherence to OIE standards and minimize trade impacts. OIE trade guidelines call on countries to base trade restrictions on sound science and, whenever possible, limit restrictions to those animals and animal products within a defined region that pose a risk of spreading disease of concern.”
