On January 30, The Food and Drug Administration (TDA) took a sample of the Amish Classic Colby from a store in Trenton, Tennessee. Tests conducted in the state lab confirmed the food was contaminated with Listeria monocytogenes.
Listeria monocytogenes is unlike many other germs because it can grow in a cold environment. Although healthy individuals may suffer only short-term symptoms, infection can cause miscarriages and stillbirths among pregnant women and may be fatal for individuals with weakened immune systems.
The TDA is currently investigating the source and extent of the contamination, urging anyone who purchased any of the items not to consume them.
The manufacturer, Deutsch Kase Haus, LLC, is instructing all wholesalers and retailers to discontinue selling their existing stock of Amish Classic Colby deli horns distributed by MDS Foods under the Amish Classic label with item number 55209 and sold as sliced deli cheese. They are also recalling lot numbers 110316V02, 110316V03 and 110316V04.
The company is also removing packaged Amish Classic Colby Cheese with item numbers 55241 and 55245 which were cut from the suspect 55209 product and wrapped at the MDS Foods manufacturing facility located in Tullahoma, Tenn.
No illnesses have been reported in Tennessee. Cooking and pasteurization are two methods to eliminate the bacteria from food.
