By now you’ve probably heard about the massive recall of roughly 6.5 million boxes of original flavor Kraft Macaroni & Cheese Dinner. Kraft recalled the product due to the possibility that some boxes may contain small pieces of metal.

Kraft mac and cheese is a go-to convenience food found in many American households. If you have any 7.25-ounce boxes sitting on your pantry shelf, take the time right now to check if they’re part of the recall. Any box that lists a “best when used by” date between “18 SEP 2015” and “11 OCT 2015” and that also has a “C2” code right below the date is part of the recall.

If you bought the product in bulk — in three-, four- or five-pack boxes — and the boxes were packaged in shrink-wrap or a larger box, ignore the date on the outer packaging, says Kraft, and refer to the dates on the individual boxes.

And what if you have a box that’s been recalled? The Kraft website says do not consume the product. You can return it to the store where you purchased it for a full refund or exchange. To date, there’ve been eight consumer complaints “and no injuries reported,” says Kraft spokesperson Joyce Hodel.

The “what if” scenario

If a child unknowingly ingests mac and cheese with metal pieces, what’s the risk?

“Similar to when kids eat pennies, it [the metal] might pass right through without any problems and come out in your child’s poop,” says Tanya Remer Altmann, MD, American Academy of Pediatrics (AAP) spokesperson and co-author of the AAP’s “Caring for Your Young Baby and Young Child.”

“The metal could also make a stop at the valve at the bottom of the stomach, or if the pieces are sharp, get lodged into the stomach, causing a hole or perforation, which would be a surgical emergency.”

If you know your child has eaten the recalled product and develops a severe stomachache, is vomiting blood or has blood in his stool, get him to the ER right away, says Altmann. If a child has these symptoms and metal is suspected, she’ll be given an X-ray.

On an up note: “Kids are pretty sensitive to tastes and textures. If they detect something unusual, they often spit it out,” adds Altmann.
