Kraft has voluntarily recalled roughly 242,000 cases of Original flavor Kraft Macaroni & Cheese Dinners due to the possibility that some boxes may contain small pieces of metal.

The recall only impacts select code dates and manufacturing codes, according to a release. The recalled product is limited to the 7.25-oz. size of the original flavor of boxed dinner with the “Best When Used By” dates of September 18, 2015 through October 11, 2015, and the code “C2″ directly below the date on each box.

Some of these boxes were sold in multi-packs that have a range of different code dates and manufacturing codes on the external packaging (box or shrink-wrap).

The affected dates of this product were sold in these four configurations:

  • 7.25 oz. box, Original flavor
  • 3-pack box of those 7.25 oz. boxes, Original flavor
  • 4-pack  shrink-wrap of those 7.25 oz. boxes, Original flavor
  • 5-pack shrink-wrap of those 7.25 oz. boxes, Original flavor

The product was shipped to customers in the U.S. and several other countries.

No other sizes, varieties or pasta shapes and no other packaging configurations are included in this recall, the company said.
