The U.S. Food and Drug Administration and the Centers for Disease Control and Prevention said on Monday the agencies were investigating a multi-state outbreak of listeria infections linked to frozen supplemental shakes manufactured by Prairie Farms Dairy Inc.

According to a CDC food safety alert, an outbreak of Listeria infections has affected 38 people across 21 states. Of those infected, 37 have been hospitalized, and 12 have died.

In the second major foodborne illness outbreak of 2025, the FDA has announced the recall of certain supplement shakes used at long-term care facilities.
