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 are 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.
During the inspection of the Crave Brothers facility in July 2013, the FDA collected a sample of Petit Frère with Truffles that was found to contain Listeria monocytogenes with the same DNA fingerprint as the outbreak strain.
