From Tennessee Department of Agriculture:
The Tennessee State Veterinarian is reporting a third detection of highly pathogenic avian influenza (HPAI) in the state. The latest occurrence affects a commercial chicken facility in Bledsoe County.
Following a sudden spike in deaths in the flock, testing at the C.E. Kord Animal Health Diagnostic Laboratory in Nashville and the National Veterinary Services Laboratory in Ames, Iowa confirmed the cause was H5N1 highly pathogenic avian influenza.
“I cannot emphasize this enough—flock owners must be aware of the threat and focused on protecting their birds,” Tennessee State Veterinarian Dr. Samantha Beaty said. “HPAI is circulating in our environment and in the wild bird population. We anticipate more detections as we move through fall and into winter. Strong biosecurity is the best way to protect the health of backyard and commercial flocks.”
HPAI is a highly transmissible disease known to be deadly for domesticated fowl. Fowl can be exposed to HPAI through human interactions and through contact with wild birds. The cases this year in Tennessee have sickened chickens, geese, and ducks in Obion, Tipton, and now Bledsoe Counties.
Animal health officials have established a 10 kilometer (6.2 mile) control zone surrounding the affected facility. Within the zone, poultry will be tested and monitored for illness and poultry movement requires permitting until the zone is released. Animal Health staff members are visiting poultry owners in-person within the control zone to explain the situation, answer questions, and provide information. If you have concerns about your location, please email Animal.Health@tn.gov or call 615-837-5120 and staff will help determine if your flock is within the zone.
Although HPAI does not pose a food safety risk, no infected poultry will be allowed to enter the food supply. Poultry and eggs are safe to eat when handled and cooked properly. The risk of human infection with avian influenza during poultry outbreaks is very low. In fact, no transmission to humans was reported during the outbreak that affected commercial poultry farms in Tennessee in 2017.
Guidance for Bird Owners
- Wash your hands thoroughly before and after interacting with domesticated birds.
- Dedicate a pair of shoes to only be worn in coops or poultry houses and clean those shoes after each visit.
- Regularly disinfect any equipment used in coops or poultry houses.
- Deter wild birds from interacting with domesticated birds. Consider hanging pie pans or other noisemakers in trees or, if local rules allow, set off firecrackers intermittently or when you see vultures or geese on your property.
- Look for signs of illness and report a sudden increase in the number of sick birds or bird deaths to the Tennessee State Veterinarian’s office at 615- 837-5120 and/or USDA at 1-866-536-7593.

State officials and partners have extensive experience in effectively containing the virus. Control of avian influenza includes coordination of resources and response, and protocols for quarantine, testing, disposal, cleaning, disinfection, and monitoring.
In Tennessee, more than 600 family farms contribute to the commercial poultry industry. The state is a global leader for primary breeders, and an estimated 45 percent of the chicken consumed worldwide traces to genetics from Tennessee operations. Broiler chickens are among the state’s top agricultural commodities, generating $376.2 million in cash receipts in 2021.
From UT Extension, Poultry Specialist – Tom Tabler:
Backyard poultry producers MUST be on high alert regarding anything suspicious in their flocks and immediately report any sudden increase in the number of sick or dying birds to the Tennessee State Veterinarian’s office (615-837-5120) and/or USDA hotline at 1-866-536-7593. Commercial poultry growers should immediately report anything suspicious in the health condition of their flocks to their service technician.
Be aware that in some states, it is believed that bush hogging/mowing near the chicken houses or combining row crops near the houses stirred up virus-laden dust and the fans pulled the virus laden dust into the houses. We cannot control where the ducks and geese fly and large numbers of water fowl are carrying the virus right now. They secrete the virus in their nasal secretions and in their manure. If they drop manure near your poultry houses and you stir up the manure and the virus becomes airborne, the fans may pull the virus into the house. It is critical to use extra caution and rachet up what you already may consider a high level of biosecurity as we move deep into the fall and winter seasons. There is a large amount of virus out there right now and we may likely see more avian influenza cases in the coming weeks and months.
We cannot medicate or vaccinate our way out of the current HPAI outbreak in the U.S. Therefore, a strong biosecurity program is the best defense every poultry premises has to protect their flock. Poultry producers need to be careful when working in or near their flock and take every precaution to avoid tracking the avian influenza virus into their chicken coop, pen or poultry house. Avian influenza will not magically appear in a flock. It has to be put there somehow, often times by someone unknowingly tracking it into a facility. However, that is not the only method by which the virus moves. So, be extra careful and maintain a high degree of biosecurity for the foreseeable future. We will likely see more cases of HPAI as migration season continues for wild waterfowl and we move deeper into fall and winter.
