USDA Confirms Highly Pathogenic H7N3 Avian Influenza in a Commercial Flock in Chesterfield County, South Carolina
from the USDA Animal and Plant Health Inspection Service (APHIS)
The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic H7N3 avian influenza (HPAI) in a commercial turkey flock in Chesterfield County, South Carolina. This is the first confirmed case of HPAI in commercial poultry in the United States since 2017. It appears this HPAI strain mutated from a low pathogenic strain that has been found in poultry in that area recently.
No human cases of this H7N3 avian influenza virus have been detected and there is no immediate public health concern. As a reminder, the proper handling and cooking of poultry and eggs to an internal temperature of 165 ˚F kills bacteria and viruses.
