A total of five persons infected with the outbreak strain of Listeria monocytogenes have been reported from four states. The number of ill persons identified in each state is as follows: Illinois (1), Indiana (1), Minnesota (2), and Ohio (1).
All five ill persons were hospitalized. One death was reported in Minnesota. One illness in a pregnant woman resulted in a miscarriage.
A collaborative investigation by local and state public health and regulatory agencies, CDC, and the U.S. Food and Drug Administration indicates that Les Frères, Petit Frère, and Petit Frère with Truffles cheeses made by Crave Brothers Farmstead Cheese Company is the likely source of this outbreak.
On July 3, 2013, Crave Brothers Farmstead Cheese Company of Waterloo, Wisconsin voluntarily recalled its Les Frères, Petit Frère, and Petit Frère with Truffles cheeses with make dates of July 1, 2013 or earlier due to possible Listeria monocytogenes contamination.
The recalled cheeses were distributed nationwide through retail and foodservice outlets as well as by mail orders.
