Frito-Lay is recalling a limited number of 13 oz. bags of Lay’s Classic Potato Chips after being alerted by a consumer contact that the product may contain undeclared milk.

The bags of chips affected by recall were distributed to certain retail stores and e-commerce distributors in Oregon and Washington and were available for sale beginning Nov. 3, 2024.

“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 Food and Drug Administration said in the recall notice posted Thursday.

No allergic reactions related to the recall have been reported, according to the recall. Additionally, no other Lay’s products, flavors, sizes or variety packs are affected. 

The recalled chips include Lay’s Classic Potato Chips, in flexible 13 oz. (368.5 grams) bags with UPC code 28400 31041, a “Guaranteed Fresh” date of 11 Feb 2025, and one of either two manufacturing codes: 6462307xx or 6463307xx.

General guidelines from the FDA advise consumers who have purchased any recalled food to dispose of the product or return it to the retailer for a full refund.
