YoCrunch yogurt products are being pulled from store shelves nationwide due to a safety concern -- plastic in the dome -- its manufacturer announced Monday.

However, the plastic pieces are confined only to the dome topper, which contains candy or granola; no plastic has been found in the separate cup which contains the yogurt. The recall applies to all flavors and sizes of YoCrunch products, including the granola, Twix, and Oreo. The products are sold at grocery stores nationwide.

Danone U.S., parent company of YoCrunch yogurt, announced the voluntary recall Tuesday over plastic pieces reportedly found in the dome topper.
