Avian Influenza H7 Outbreak 2017

Yesterday (3/5/17) the USDA confirmed the first case of highly pathogenic H7 avian influenza (HPAI) of the year for 2017. The strain was detected on a Tyson contracted chicken farm in Lincoln County, Tennessee. It is the first time HPAI has been detected in the state of Tennessee.

The facility with the confirmed case of HPAI has been placed under quarantine. Approximately 30 surrounding farms will also be placed under quarantine and tested for the strain. So far, 73,500 birds will be culled to stop the spread.

The USDA should have more information about the exact strain of the virus soon. Tyson is taking biosecurity precautions, such as disinfecting all vehicles entering farms and banning non-essential visitor access.

Symptoms of HPAI

Birds affected with Highly Pathogenic Avian Influenza may exhibit one or more of the following symptoms. Keep a close eye on your flock and if you suspect your birds have been affected by HPAI call the USDA Veterinary Service office at 1-866-536-7593.
  • Sudden death without showing clinical signs
  • Lack of energy and/or appetite
  • A decrease in egg production
  • Swelling of the head, eyelids, comb, wattles, and hocks
  • Purple discoloration of the wattles, combs, and legs
  • Soft-shelled or misshapen eggs
  • Nasal discharge
  • Coughing and sneezing
  • Lack of coordination
  • Diarrhea

Take Biosecurity Measures to Prevent HPAI

In the wake of the avian influenza outbreaks of 2015 and 2016, we are urging producers to assess their biosecurity measures. Make sure your facility is biosecure to prevent diseases, like highly pathogenic avian influenza, from infecting your flock.

Check out our Biosecurity Resource page for detailed information on keeping your facility biosecure.
