A Black Earth company recalled about 99 pounds of beef tongue.
The U.S. Department of Agriculture said Black Earth Meat Market recalled the products because they may not have had the tonsils completely removed.
The recall involves various size cases of Black Earth Meats Natural Beef Tongues and Black Earth Meats Local Beef Tongues produced by the Black Earth-based company on Oct. 8, 11, 17 and 18.
The products were distributed to a restaurant in Wisconsin and a distributor in Illinois.
The USDA said the problem was discovered during a routine food safety assessment. Cattle tonsils have to be removed from food to avoid exposing people to mad cow disease. USDA said there is no indication that any of the cattle slaughtered showed any signs of the disease.
