The FDA and CDC, in collaboration with state and local partners, are investigating a multi-state, multi-year outbreak of Listeria monocytogenes infections linked to requeson, a soft cheese similar to ricotta, manufactured by Clover Hill Dairy, LLC of Mechanicsville, MD. On June 14, 2026, The Maryland Department of Health announced an expanded consumer advisory for all cheese products made by Clover Hill Dairy (Mechanicsville, MD), due to possible Listeria monocytogenes contamination. The FDA is working with Maryland state partners and Clover Hill Dairy to initiate an expended recall of all products made at the facility. As part of this investigation, FDA and state partners collected and analyzed samples. To date, six product samples of requeson cheese have tested positive for Listeria monocytogenes and matched the outbreak strain. Additionally, one environmental sample, collected by Maryland state partners, tested positive for Listeria monocytogenes and matched the outbreak strain. The FDA’s investigation is ongoing, and this advisory will be updated with more information as it becomes available. There are 9 ill patients,8 hospitalization, and 1 death due to the consumption of the product. States with cases are MD, NY, and VA. @ https://www.fda.gov/food/outbreaks-foodborne-illness/outbreak-investigation-listeria-monocytogenes-soft-cheese-june-2026?utm_medium=email&utm_source=govdelivery
