March 7, 2017: USDA’s National Veterinary Services Laboratories (NVSL) has confirmed the full subtype for the highly pathogenic H7 avian influenza reported in Lincoln County, TN. The virus has been identified as North American wild bird lineage H7N9 HPAI based upon full genome sequence analysis of the samples at the NVSL. All eight gene segments of the virus are North American wild bird lineage. This is NOT the same as the China H7N9 virus that has impacted poultry and infected humans in Asia. While the subtype is the same as the China H7N9 lineage that emerged in 2013, this is a different virus and is genetically distinct from the China H7N9 lineage.
January 15, 2016: The United States Department of Agriculture Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic H7N8 avian influenza (HPAI) in a commercial turkey flock in Dubois County, Indiana.
This is a different strain of HPAI than the strains that caused the 2015 outbreak. There are no known cases of H7N8 infections in humans.
Yes, food is safe. Always be sure to properly handle any food.
Properly cooked and handled poultry is not a source of infection for avian influenza viruses of any strain. Furthermore, the likelihood of infected poultry entering the U.S. food supply is extremely low due to import restrictions, extensive disease testing, and federal inspection programs. Properly prepared and cooked poultry is safe to eat. Cooking poultry to an internal temperature of 165 degrees F. kills the avian influenza virus, as well as other organisms. While most human illnesses have resulted from direct contact with sick or dead birds, a small number have resulted from eating raw poultry or poultry products, so proper cooking is important in areas where avian influenza might be present

Scientists See Long Term Threat
In this 2015 article
published in Emerging Infectious Diseases researchers suggested H5N2 and other descendants of the H5N8 avian flu virus that arose if the previous year in Asia may pose a long term threat to poultry and wild waterfowl in the Northern Hemisphere.
The researchers from The US Geological Survey's National Wildlife Health Center in Madison, Wisconsin traced the emergence of H5N8 and its offspring including H5N2. Their data suggests H5N8 arose from reassortment of HPAI H5N1 with LPHAI viruses. Since first detected the virus has been found in poultry and wild waterfowl in Europe, Taiwan, Japan, Canada and the United States (west and central). The scientists further posture the persistence of H5N8 and reassortments that have maintained high pathogenicity in poultry and adaptation to wild waterfowl means they could be present for a time to come.
To those that are familiar with the nature of these viruses also recognize as the threat persists so does the chance these viruses will reassort with viruses from other species such as swine, which could then pose a threat to human health.
