Almost all Kellogg’s Cereals & Nutri-Grain Bars that currently bear a “K” are now O/U certified. Products with a plain “K” are certified O/U pareve and products with a KD or KDE are certified O/U dairy or O/U dairy equipment respectively. In coming months the O/U symbol will replace the “K” on new packaging of these Kellogg’s products. The only exception is Kellogg’s Mini-Wheats Unfrosted Cereal, which is NOT O/U certified, even when bearing a “K” on the package.
