(NEXSTAR) – Potentially-contaminated popcorn that hit grocery store shelves in a number of U.S. states is now under recall, the Food and Drug Administration warns.

Snak King Corporation issued the voluntary recall after discovering that certain five-ounce packages of O Organics Sea Salt Organic Popcorn may have an undeclared milk allergen.

The recalled items were sold in Connecticut, Delaware, Maryland, New Jersey, New York, Pennsylvania, Virginia, Washington DC, Illinois, Indiana, Iowa, California, Hawaii, Nevada, Oregon, Washington, Alaska, and Idaho.

Popcorn bags, which all have the “best by” dates of 9/24/2022 – 9/25/2022, landed on shelves in ACME, Safeway, King’s, Balducci’s, Jewel-Osco, Andronico’s Community Markets, Vons, Pak ‘N Save, Albertsons, Eagle, Carrs-Safeway, Haggen and Pavilions locations.

The UPC number for the recalled items is 079893 403038.

While a milk allergen may be seriously harmful and even life-threatening for people who are allergic, as of Tuesday there were no reports of illness.

Anyone who bought a now-recalled O Organics bag of popcorn is urged not to eat it, and to return it to the store where it was purchased for a full refund.

Consumers can call the company with any questions at (626) 363-7711.
