A recall of Lay’s potato chips was upgraded this week to the Food and Drug Administration’s most-severe level.
The agency on Monday assigned a Class I recall to 6,344 bags of Lay’s Classic Potato Chips due to “undeclared milk,” which means that milk wasn’t listed on the product ingredients.
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.
The affected bags also include those distributed to certain retail stores and e-commerce distributors in Oregon and Washington and have been available to purchase since Nov. 3.
The recall pertains to 13 oz. (368.5 grams) bags of Lay’s Classic Potato Chips, with a “Guaranteed Fresh” date of Feb. 11 2025. In addition to the “Guaranteed Fresh” date, corresponding bags must have manufacturing code 6462307xx or 6463307xx.
To date, no other Lay’s products, flavors or sizes have been recalled. Variety packs have also remained unaffected. The Daily News has reached out to Frito-Lay for comment.
Class I recalls are the most serious of the FDA’s three levels, and pertains to recalls involving “a reasonable probability that the use of, or exposure to, a violative product will cause serious adverse health consequences or death.”
The New York Times suspects the Class I upgrade might have something to do with the Trump administration pressing pause on health and science agencies’ public communications through Feb. 1, pending review by a presidential appointee or designee.
