USDA confirms HPAI in five additional states

Must read

WASHINGTON — The USDA’s Animal and Plant Health Inspection Service has confirmed the presence of highly pathogenic avian influenza in a non-commercial, mixed-species backyard flock (non-poultry) in Berkshire County, Mass.; a non-commercial, mixed-species backyard flock (non-poultry) in Johnson County, Wyo.; a commercial poultry flock in Johnston County, N.C.; a non-commercial, backyard chicken flock (non-poultry) in Franklin County, Ohio; and a non-commercial, backyard chicken flock (poultry) in Kidder County, N.D.

Samples from all the flocks were first tested at state laboratories that are part of the National Animal Health Laboratory Network. Results were subsequently confirmed at the APHIS National Veterinary Services Laboratories (NVSL) in Ames, Iowa. Samples from the Massachusetts flock were tested at the Connecticut Veterinary Medical Diagnostic Laboratory. Samples from the Wyoming flock were tested at Wyoming State Veterinary Laboratory. Samples from the North Carolina flock were tested at the Rollins Diagnostic Laboratory. Samples from the Ohio flock were tested at the Animal Disease Diagnostic Laboratory. Samples from the North Dakota flock were tested at the Veterinary Diagnostic Laboratory.

APHIS is working closely with state animal health officials in both states on a joint incident response. State officials quarantined the affected premises, and birds on the properties will be depopulated to prevent the spread of the disease. Birds from the flocks will not enter the food system.

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 all poultry and eggs to an internal temperature of 165 degrees F is recommended as a general food safety precaution.

As part of existing avian influenza response plans, Federal and State partners are working jointly on additional surveillance and testing in areas around the affected flocks. The United States has the strongest AI surveillance program in the world, and USDA is working with its partners to actively look for the disease in commercial poultry operations, live bird markets and in migratory wild bird populations.

Anyone involved with poultry production from the small backyard to the large commercial producer should review their biosecurity activities to assure the health of their birds. APHIS has materials about biosecurity, including videos, checklists, and a toolkit available at http://healthybirds.aphis.usda.gov/

USDA will report these findings to the World Organization for Animal Health 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. OIE trade guidelines also call on member countries to not impose bans on the international trade of poultry commodities in response to notifications in non-poultry.

In addition to practicing good biosecurity, all bird owners should prevent contact between their birds and wild birds and report sick birds or unusual bird deaths to State/Federal officials, either through their state veterinarian or through APHIS’ toll-free number at 866-536-7593. The Animal Health Protection Act authorizes APHIS to provide indemnity payments to producers for birds and eggs that must be depopulated during a disease response. APHIS also provides compensation for disposal activities and virus elimination activities. For more information, visit aphis.usda.gov.
