WASHINGTON — The United States Department of Agriculture’s Animal and Plant Health Inspection Service has confirmed the presence of highly pathogenic avian influenza in two non-commercial backyard flocks (non-poultry) in Connecticut and Iowa, a flock of commercial layer chickens in Cecil County, Maryland, a commercial mixed species flock in Charles Mix County, South Dakota, and a flock of commercial broiler chickens in Stoddard County, Missouri.
The cases were confirmed at the APHIS National Veterinary Services Laboratories in Ames, Iowa. APHIS is working closely with state animal health officials in each of these states on joint incident responses. 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 in birds 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 Fahrenheit kills bacteria and viruses.
Response
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 aphis.usda.gov/aphis/ourfocus/animalhealth/animal-disease-information/avian/defend-the-flock-program/dtf-resources/dtf-resources.
Reporting
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 member countries to not impose bans on the international trade of poultry commodities in response to such notifications in non-poultry.
APHIS will continue to announce the first case of HPAI in commercial and non-commercial backyard flocks detected in a state but will not announce subsequent detections in the state. All cases in commercial and non-commercial backyard flocks will be listed on the APHIS website at aphis.usda.gov/aphis/ourfocus/animalhealth/animal-disease-information/avian/avian-influenza/2022-hpai.
Precautions. 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 1-866-536-7593. APHIS urges producers to consider bringing birds indoors when possible to further prevent exposures.
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. Additional information on biosecurity for non-commercial backyard flocks can be found at healthybirds.aphis.usda.gov.
