BATTLE CREEK, MICH. — The Kellogg Co.  is recalling about 3.2 million boxes of Mini-Wheats in the U.S., Canada and Mexico due to possible fragments of metal mesh that may have gotten into the products. The company said the metal contamination may be due to a faulty manufacturing part.

The recall is expected to cost the company between $20 million and $30 million.

The recalled cereals include Frosted Mini-Wheats Bite Size Original and Mini-Wheats Unfrosted Bite Size with the letters KB, AP or FK before or after the “Best if Used Before” date, which ranges from April 1, 2013 to Sept. 21, 2013.

"Because our number one priority is the quality and safety of our foods, as a precautionary measure, Kellogg voluntarily recalled certain packages of Mini-Wheats Bite Size cereal," said Kris Charles, company spokesperson. "No other cereals are impacted and there have been no reports of any injuries associated with these foods."
