Campbell Soup Co. is recalling nearly15 million pounds of canned "SpaghettiOs with Meatballs" because of possible under-processing, the U.S. agriculture department said.

The recall includes 14.75-ounce cans with a use-by date between June 2010 and December 2011 of three varieties of the product: "SpaghettiOs with Meatballs," "SpaghettiOs A to Z with Meatballs" and "SpaghettiOs Fun Shapes with Meatballs (Cars)."

Consumers who have purchased those products with a plant code of "EST4K" should not eat them and should return them to the store where they were purchased for an exchange or full refund, Campbell Soup said.
