Kraft Foods is recalling about 6.5 million boxes of its signature Macaroni & Cheese because some of the boxes may contain small pieces of metal.
The recall applies to 7.25oz packs of original flavour boxes that have "best when used by" dates ranging from 18 September 2015 through 11 October 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.
Some 242,000 cases of the product are being recalled.
Kraft said it was aware of eight incidents of consumers finding metal in the boxes, but has not been informed of any injuries.
It told consumers not to eat the macaroni and return it to the store where it was purchased for a full refund.
"We believe a piece of stainless steel got wedged in a metal piece of equipment, which may have generated friction that resulted in small pieces of metal potentially falling into the product," Joyce Hodel, a Kraft spokeswoman, said in a statement.
"We deeply apologise to the consumers we have disappointed."
The recall comes at a time when Kraft's Macaroni & Cheese products, a staple for generations of Americans, face increasing competition from smaller brands with more natural ingredients.
