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. All bird owners, whether commercial producers or backyard enthusiasts, should continue to practice good biosecurity, 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 can be found at www.aphis.usda.gov/animalhealth/defendtheflock.

Avian influenza, or "bird flu," is a respiratory disease of birds caused by influenza A viruses. These viruses can infect domestic poultry (such as chickens, turkeys, ducks, and geese) and are found naturally in wild birds (such as ducks, gulls, and shorebirds). Low pathogenic avian influenza (LPAI) occurs naturally in wild birds and can spread to domestic birds. In most cases, it causes few or no outward signs of infection. LPAI viruses are common in the United States and around the world. High pathogenic avian influenza (HPAI) is extremely infectious, often fatal to domestic poultry, and can spread rapidly from flock to flock. If HPAI is found in the United States, we must eradicate it to protect our country’s flocks and to keep trade flowing.

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service is launching a new outreach campaign focused on preventing the spread of infectious poultry diseases in both commercial and backyard poultry. Considering the devastating impact of the highly pathogenic avian influenza outbreak in 2014-2015, as well as this year’s outbreak of virulent Newcastle disease, the timing is right for everyone in the poultry community to work together to protect the health of our nation’s flocks. The “Defend the Flock” campaign to promote biosecurity combines and updates two previous campaigns that were each targeted at a specific segment of the poultry population.
