Cuisinart is recalling some eight-million food processors. People have reported finding broken blades in their food. The consumer product safety commission says 30 people have cut their mouths or broken teeth on the blade pieces. The recall involves 22 food processor models. Conair, which owns Cuisinart, says the blade can crack over time. The company says that you can tell if you have a recalled model by looking at the blade. The defective blades will have four rivets.
