In September 2022, the CDC, public health and regulatory officials in several states ant the FDA investigated an outbreak of Listeria monocytogenes infections associated with soft cheese manufactured by Old Europe Cheese, Inc. located in Michigan.

As of September 28, 2022, six people infected with the outbreak strain of Listeria had been reported from 6 states. Five people had been hospitalized. No deaths were reported. Sick people's samples were collected from August 6, 2017 to August 5, 2022.

State and local public health officials interviewed people about the foods they ate in the month before they got sick. Of the five people interviewed, four (80%) reported eating brie or camembert cheese. Most people did not remember the brand of the cheese they ate, but one person reported eating Lidl Premium Brand Brie. Old Europe Cheese is the only manufacturer of Lidl Premium Brand Brie.

FDA, with assistance from the Michigan Department of Agriculture and Rural Development, inspected the Old Europe Cheese facility in Michigan and collected samples for testing. WGS showed that the Listeria found in the cooling room was closely related genetically to Listeria from sick people’s samples. This provided more evidence that people likely got sick from eating cheese made by Old Europe Cheese. On September 30, 2022, Old Europe Cheese, Inc. recalled their brie and camembert cheese. The company has also temporarily stopped producing these cheeses
