Kraft Macaroni & Cheese recalled due to metal fragments

Kraft Foods is recalling 242,000 cases of original flavor Kraft Macaroni & Cheese -- that's 6.5 million boxes -- because some of the boxes contain small pieces of metal.

The boxes have "best when used by" dates ranging from Sept. 18, 2015 through Oct. 11, 2015 and are marked with the code "C2." They were sold throughout the U.S., Puerto Rico, and in some countries in the Caribbean and South America. A complete list of affected products is posted on Kraft's website.

The recall covers 7.25 ounce boxes that were sold individually and in packs of three, four and five. The company says no other varieties, pasta shapes or package sizes are affected by the recall.

Kraft Foods Group Inc. says it is aware of eight incidents of consumers finding metal in the boxes, but hasn't been informed of any injuries.

The company says consumers shouldn't eat the macaroni and should return it to the store where it was purchased for a full refund.

A request for interview on the recall Tuesday night was declined by a company representative.

Consumers also can contact Kraft Foods Consumer Relations at 1-800-816-9432 between 9 a.m. and 6 p.m. Eastern time.
