TreeHouse Foods issued a voluntary recall last week for its frozen waffle products that are sold at many retailers in the U.S. and Canada.

Treehouse Foods, which makes the waffles, is voluntarily recalling some of its products—including select Kodiak Cake, Harris Teeter, and Good & Gather waffles—due to the potential to be contaminated with Listeria monocytogenes.

Wegmans has issued a recall for a variety of frozen waffles and pancakes due to potential listeria contamination. The local recall comes amid national concerns over Listeria in frozen breakfast products and in meat.
