FDA expands Clover Hill Dairy recall as Listeria outbreak grows

Pull the cheese now, not after service. The FDA’s expansion of the Clover Hill Dairy recall turned a consumer alert into a kitchen-ordering problem for restaurants, with all cheese products from the Mechanicsville, Maryland, plant now included, from requeson and cuajada to hard cheeses.

The agency said restaurants, retailers and consumers should not eat, sell or serve the recalled cheese. It also said any surface, pan, bin or container that touched the product needs to be cleaned and sanitized, because Listeria monocytogenes can survive in refrigerated temperatures and spread to other foods and equipment. For cooks and managers, that means the recall does not stop at the label in the walk-in. It reaches prep tables, deli trays, slicers, storage tubs and anything else that handled the cheese before it hit salads, tacos, sandwiches, breakfast plates or sauces.

The public-health stakes are already serious. As of the Centers for Disease Control and Prevention’s June 18 update, the outbreak had sickened 9 people, hospitalized 8 and killed 1. CDC said the recalled cheese was sold at Clover Hill Dairy’s retail market, at farmers markets and through other distributors, and it was distributed in North Carolina, New York, Virginia, Maryland, New Jersey and Washington, DC. That reach matters in restaurant kitchens because an operator may not buy directly from the dairy and still end up with the product through a third-party supplier.

The recall also got broader because the cheese may not always look like Clover Hill Dairy cheese on the shelf. FDA said some recalled product may have been repackaged or relabeled under KESSO, QUESOS LA RICURA, IZALCO, DE MI PUEBLO and RIO LINDO, which raises the odds that a receiving clerk misses it if only one brand name is on the invoice. The agency said the outbreak strain matched requeson samples supplied by Clover Hill Dairy, along with a positive environmental sample tied to the same strain.

The timeline shows how long this can simmer before it reaches a kitchen. Illness samples in the outbreak date back to March 6, 2023. The investigation began after the Suffolk County Health Department in New York reported two related Listeria cases in one family on May 13, 2026. Maryland health officials issued a consumer advisory on June 3 and suspended Clover Hill Dairy’s operating license on May 30, after the earlier advisory covered its requesón and soft ricotta cheese products. For restaurant managers, the operational lesson is blunt: verify every lot, hold anything questionable, keep sanitation logs current and make sure delivery staff know a recall notice when they see one.
