In another food recall, Ben & Jerry’s Coconut Seven Layer Bar bulk tubs and Ben & Jerry’s Chunky Monkey pints of ice cream have been recalled for a possible nut allergy. Unilever (UN) recalled the ice cream because they may inadvertently contain tree nuts such as almonds, Brazil nuts, and hazelnuts, which were not declared on the label.

According to Unilever, the recalled ice cream does include a “contains walnuts” and a “may contain other tree nuts” on the label. However, the affected ice cream may cause a life-threatening allergic reaction if consumed.

The recalled products include Ben & Jerry’s Coconut Seven Layer Bar bulk product sold in a 2.4-gallon tub with a consumer UPC code of 076840104246. It has a best by date of SEP1520BJ4.

Also, recalled was Ben & Jerry’s Chunky Monkey sold in a pint tub (473 mL) with a consumer UPC code of 076840100354. It has best by dates of AUG2820BH2, AUG2920BH2, and AUG3020BH2.

The recalled ice cream was manufactured in the U.S. and sold nationwide. The Chunky Monkey pints were sold at retail locations while the recalled Coconut Seven Layer Bar tubs were sold wholesale and at scoop shops. The product was not shipped outside the U.S., Unilever said.

No other Ben & Jerry’s products were affected by the recall.

Unilever discovered the issue during its production operations as its investigation indicated that that the issue stemmed from an error with one of its nut suppliers. It has not received any reports of illness from the recalled ice cream. The company said it is making the recall “out of an abundance of caution” and has remediated the issue.

Consumers are urged not to consume the recalled Ben & Jerry’s products. They should retain the outer container and call 1-833-236-1237, 24 hours a day, seven days a week for more information.

Unilever has conducted the recall in accordance with the U.S. Food and Drug Administration.
