Overview

• DATCP confirmed HPAI H5N1 in a commercial poultry flock in Jefferson County and is coordinating with USDA animal health officials.
• The affected farm is under quarantine with restrictions on the movement of poultry and poultry products.
• All birds on the property will be depopulated, and none from the flock will enter the food supply.
• Authorities established a 10‑kilometer control area to limit poultry movement, and producers can check their status using DATCP’s mapping tool.
• Livestock owners are urged to strengthen biosecurity and report unusual illness or deaths via DATCP’s Animal Disease Reporting webpage, while health officials monitor exposed workers and say public risk remains low.
