Based on epidemiological information collected by CDC, a total of 12 people infected with the outbreak strain of Listeria have been reported from 4 states. Sick people's samples were collected on dates ranging from March 6, 2023, to June 2, 2026. Of the 10 people interviewed, 9 reported eating any cheese. Two people (33%) reported eating requeson made by Clover Hill Dairy. There have been 10 hospitalizations, and one death reported.
