WASHINGTON, January 16, 2016 -- The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of H7 avian influenza in 9 flocks in southwestern Indiana. These new cases were identified as part of surveillance testing in the control area surrounding the initial highly pathogenic avian influenza (HPAI) case. Testing is currently ongoing at the National Veterinary Services Laboratories in Ames, Iowa to determine the pathogenicity of these new cases.
No cases of HPAI H7N8 virus infection have been reported in humans at this time, and no human infections associated with avian influenza A viruses of this particular subtype (i.e., H7N8) have ever been reported. As a reminder, the proper handling and cooking of poultry and eggs to an internal temperature of 165 ˚F kills bacteria and viruses, including HPAI.
APHIS continues to work closely with the Indiana State Board of Animal Health on a joint incident response. State officials quarantined the affected premises and depopulation of birds on the affected premises has already begun. Depopulation prevents the spread of the disease. Birds from the flock will not enter the food system.
As part of existing avian influenza response plans, Federal and State partners continue to work on additional surveillance and testing in the nearby area. The rapid testing and response in this incident is the result of months of planning with local, state, federal and industry partners to ensure the most efficient and effective coordination. Since the previous HPAI detections in 2015, APHIS and its state and industry partners have learned valuable lessons to help implement stronger preparedness and response capabilities. In September, APHIS published a HPAI Preparedness and Response Plan that captures the results of this planning effort, organizing information on preparatory activities, policy decisions and updated strategy documents.
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. To facilitate such a review, a biosecurity self-assessment and educational materials can be found at http://www.uspoultry.org/animal_husbandry/intro.cfm
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 USDA’s toll-free number at 1-866-536-7593. Additional information on biosecurity for backyard flocks can be found at http://healthybirds.aphis.usda.gov.
Additional background
Avian influenza (AI) is caused by an influenza type A virus which can infect poultry (such as chickens, turkeys, pheasants, quail, domestic ducks, geese and guinea fowl) and is carried by free flying waterfowl such as ducks, geese and shorebirds. AI viruses are classified by a combination of two groups of proteins: hemagglutinin or “H” proteins, of which there are 16 (H1–H16), and neuraminidase or “N” proteins, of which there are 9 (N1–N9). Many different combinations of “H” and “N” proteins are possible. Each combination is considered a different subtype, and can be further broken down into different strains. AI viruses are further classified by their pathogenicity (low or high)— the ability of a particular virus strain to produce disease in domestic chickens.
