If you’re a Frosted Mini-Wheats fan, then listen up.

Kellogg Co. has recalled 3.2 million boxes of Mini-Wheats Bite Size cereal due to the possibility of metal contamination. The company said “fragments of flexible metal mesh from a faulty manufacturing part” could be in the cereal.

Kellogg said the only cereals impacted in the recall are Frosted Mini-Wheats Bite-Size Original and Mini-Wheat Unfrosted with use-by dates from April to September 2013. The recall concerns some 3.2 million boxes of “Mini-Wheats” cereal sold in the United States, Canada and Mexico, according to Kellogg.
