New York - Kraft Foods is recalling 242 000 cases of original flavour Kraft Macaroni & Cheese because some of the boxes contain small pieces of metal.

The boxes have “best when used by” dates ranging from September 18, 2015, through October 11, 2015, and are marked with the code “C2”. They were sold throughout the US, Puerto Rico and in some countries in the Caribbean and South America.

The recall covers 7.25-ounce boxes that were sold individually and in packs of three, four and five.

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

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