The Food and Drug Administration (FDA) says a previously announced recall of certain bags of Lay’s potato chips in Oregon and Washington now falls into “Class I” status, its highest risk

The Food and Drug Administration has issued a Class 1 alert after Frito-Lay issued a recall for bags of Lay’s potato chips sold in Oregon and Washington.

The U.S. Food & Drug Administration has recalled a popular brand of potato chips saying the product may be high risk for some consumers.

Frito-Lay is recalling bags of Lay’s Classic Potato Chips after the FDA increased the risk level of the product to its highest level of risk classification.

OREGON & WASHINGTON -- Frito-Lay has issued a recall on 23-ounce bags of Lay's Classic Potato Chips for containing undeclared milk. "Those with an allergy or severe sensitivity to milk run the risk of a serious or life-threatening allergic reaction if they consume the recalled product," the FDA said in the release.

The FDA has classified a previous Frito-Lay potato chip recall under its highest risk level after some bags of Lay's Classic Potato Chips were found to potentially contain undeclared milk ingredients.

Frito Lay issued the recall in December after it was found that there was a potential or undeclared allergen, specifically milk, in the chips.

The FDA has upgraded a recall of Lay’s Potato Chips to the highest level possible, meaning consuming the chips will cause adverse health consequences. In December, Texas-based food manufacturer Frito Lay recalled a limited number of Lay’s Classic 13oz because the product could contain undeclared milk ingredients.

Lay recall on Lay's Classic Potato Chips across Oregon and Washington was updated to a Class 1 recall by the FDA on Thursday.

The Food and Drug Administration just raised the recall level of Lay’s Classic Potato Chips to the highest risk classification. Frito Lay issued a recall on Dec. 16 through the FDA for over 6,000 bags of Lay's Classic Potato Chips that contained "undeclared milk.

The FDA recalled Lay's Classic Potato Chips in two states under a Class 1 recall, meaning eating the product could have serious health risk for people with a milk allergy.
