A multistate Listeria outbreak has been tied to soft requeson and ricotta cheese supplied by Clover Hill Dairy. As of June 9, 2026, nine people in three states were infected, eight hospitalized, and one death was reported in Maryland. DNA fingerprinting matched the same Listeria strain in repackaged retail cheese and in an unopened 18-pound bucket of requeson from the dairy. Clover Hill Dairy and Nelson and Isa Lacteos have recalled the product, which was sold through late May in North Carolina, New York, Virginia, Maryland, New Jersey, and Washington, DC, often relabeled or repacked. Maryland has suspended the dairy's operating license. Sources: CDC, FDA.
