A Kentucky company is recalling about 215,660 pounds of frozen stuffed pepperoni pizza sandwich products, known as Hot Pockets Pepperoni Pizza.

Nestlé Prepared Foods Co. said the Hot Pockets may contain foreign materials.

Spokeswoman Roz O'Hearn said the reported foreign substance -- hard red plastic as well as clear flexible rubber-like material -- might have splintered off from a testing device and some of it could be buried inside with sharp edges.

The recall includes 54-ounce, 12-pack cartons of "HOT POCKETS PEPPERONI PIZZA" brand stuffed sandwiches. Printed on the side of each carton is "8157544614D," "EST 7721A," and "BEST BEFORE JAN2010." Each carton bears the USDA mark of inspection.

The products were produced on June 5 and distributed to retail establishments nationwide.

The problem was discovered after the company received consumer complaints. Anyone concerned about an injury from eating the products should contact a doctor.

Consumers with questions about the recall should contact Nestlé Consumer Services Center at (800) 350-5016.
