Surge in Highly Pathogenic Avian Influenza Cases in the U.S. Poultry Industry

The United States poultry sector is facing renewed challenges with recent cases of highly pathogenic avian influenza (HPAI) reported on April 8. This resurgence has impacted commercial operations across the Midwest and Great Plains, signaling a troubling trend for poultry producers.

Details of the Recent Outbreak

In South Dakota, a flock of 65,800 meat turkeys in Hutchinson County tested positive for HPAI. Additionally, a separate case was identified in LaGrange County, Indiana, involving 19,500 meat ducks. These findings were officially reported by the United States Department of Agriculture through its Animal and Plant Health Inspection Service.

Previous Cases and Trends

This latest wave follows a brief lull in reported cases. The previous confirmed incidents occurred on April 3, impacting three flocks in Indiana, which included one group of table egg pullets and two meat duck flocks. The situation escalated after the infection of 18,000 meat ducks in Lancaster County, Pennsylvania, on March 27.

Impact on Affected States

These new cases contribute to a growing tally of affected poultry flocks across various states. Indiana remains one of the hardest-hit states, with a total of 40 commercial poultry flocks impacted by HPAI in 2026. South Dakota has also reported six affected flocks thus far this year.

Ongoing Risks and Challenges

The return of the HPAI virus, following several days without new cases, highlights the persistent threat it poses to the U.S. poultry sector, particularly in production-heavy regions. Poultry producers continue to navigate these challenging circumstances in efforts to safeguard their flocks and ensure the stability of the industry.
