The Food and Drug Administration is using its most severe notice in a recall of more than 6,000 bags of chips in two states because of “undeclared milk.”

Federal health authorities have upgraded their recall of 13-ounce bags of Frito-Lay potato chips over fears that consuming the products, which may contain undeclared milk, could potentially be fatal. Last month, the Food and Drug Administration announced that Frito-Lay was voluntarily recalling a limited batch of products.

December, some 6,000 bags of Lay’s chips were recalled over a health hazard listed by the FDA in its most serious category.

Class I, according to the FDA, means exposure to or consumption of the product could cause "serious adverse health consequences or death."

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 Frito-Lay voluntary recall on a limited number of Lay's Classic potato chips due to an undeclared allergen has been updated by the FDA to Class 1.

The oversight could result in “death,” at least for those with a milk allergy or sensitivity, says the FDA. FDA initiated the recall on Dec. 13 and announced three days later that it was recalling the chips due to a potential or undeclared allergen. At present, no allergic reactions have been reported.

A December recall on Lay’s Potato Chips sold in two states has been escalated to the FDA’s highest risk level, but no allergic reactions have been reported.

The Food and Drug Administration (FDA) has ordered the recall of Lay's potato chips in Oregon and Washington due to the presence of an undeclared ingredient that could be harmful to health. Consumers are advised to check their pantries and dispose of any bags of Lay's potato chips that match the description of the affected product.
