The Food and Drug Administration (FDA) has issued a warning to consumers about a potato chip recall. The FDA says Frito-Lay has issued a voluntary recall on some of its Lay's Classic Potato Chips. The FDA says the recall involves two bag sizes of the chips. Those are the 13-ounce Lay's Classic Party Size Potato Chips and the 15 and 5/8 ounce Lay's Classic Mix and Match Potato Chips. 

The FDA says some of the chips may have been contaminated with undeclared milk ingredients from the company's sour cream and onion potato chips. The agency says milk is a common food allergen.

At this time there have been no reports of any problems.
