TreeHouse Foods has expanded a voluntary recall to include frozen toaster waffle, Belgian waffle and pancake products, due to potential listeria contamination, the company announced Thursday.

The recall of hundreds of frozen waffles has been expanded and now includes pancakes and Belgian waffles. TreeHouse Foods added more items on the list of recalled products to include all products made at a single facility that were still within the items’ shelf lives, the company said in a news release.

The private-label company said the recall now includes frozen toaster waffles, Belgian waffles and pancake products produced at an Ontario plant.
