Pinnacle Foods Group has announced a voluntary recall of Aunt Jemima frozen pancakes because they may have been cross-contaminated with soy protein.

The recalled varieties were distributed nationwide in cardboard boxes and have a "use by date" of Nov. 1, 2011 through Oct. 16, 2011. 

The company said affected varieties include:

• Aunt Jemima Pancakes Buttermilk Low Fat, 12/14.5oz., UPC 19600-05100
