Federal health officials are warning consumers in New York, Virginia, Maryland, and the greater Mid-Atlantic region to check their refrigerators immediately. A multistate Listeria monocytogenes outbreak linked to requesón and soft ricotta cheese made by Clover Hill Dairy LLC has killed one person and sent seven others to the hospital, the Centers for Disease Control and Prevention announced on June 5, 2026.
A total of nine people have now been confirmed ill across Maryland, New York, and Virginia. The most alarming detail: illness samples were collected as far back as March 2023, meaning this outbreak may have been active — and undetected — for more than three years before a formal recall was issued.
