Outbreak investigation

February 12, 2021
The FDA, along with CDC and state and local partners, are investigating a multistate outbreak of Listeria monocytogenes infections potentially linked to Hispanic-style fresh and soft cheeses.
FDA has initiated an investigation and is collecting information to try to determine the source of the outbreak. Although the investigation is ongoing, CDC’s analysis of epidemiologic information indicates that Hispanic-style fresh and soft cheeses are the leading hypotheses for the cause of the illnesses. No specific type or brand of cheese has been confirmed as the source of illness. CDC reported that seven people infected with the outbreak strain of Listeria monocytogenes have been reported in Connecticut, Maryland, New York, and Virginia. Six of the seven ill people are Hispanic. Of the four people interviewed, three reported eating at least one type of Hispanic-style fresh and soft cheeses, and all three reported eating queso fresco.
FDA is in the beginning stages of this investigation, and there may be additional products impacted by this outbreak. As this outbreak investigation continues, the FDA will provide additional updates as more information becomes available.
