Danone North America has recalled 3,521 cases of Greek yogurt for a possible peanut allergy risk. The Light & Fit Greek Crunch Nonfat Yogurt & Toppings S’Mores Flavor may contain peanuts in the topper ingredients, which were not disclosed on the label.

The recalled Greek yogurt has an expiration date of December 30, 2018, stamped on the top of the topper as well as on the side of the cup. The product was sold in single-serve 5 oz cups with a clear plastic topper with mix-in ingredients. It has a UPC code of 36632 03825.

The recalled yogurt was distributed throughout Connecticut, Illinois, Iowa, Maryland, Massachusetts, Michigan, Missouri, New Jersey, New York, Ohio, Pennsylvania, Texas, and Wisconsin.

To get a full refund of the recalled Greek yogurt, consumers can return them to the place of purchase. The company is also urging consumers that have a peanut allergy not to consume the yogurt. Questions about the recall can be directed to Danone at 1-877-326-6668.

According to the company, consumers with peanut allergies may run the risk of a serious or life-threatening reaction if they consume the recalled yogurt.

The peanut contamination of the yogurt was discovered after some of the products included the wrong topper ingredients. Danone said this is the only product affected by the recall.
