Thousands of cases of Wish-Bone Ranch Salad Dressing have been voluntarily recalled after a consumer found a bottle contained a different dressing than labeled, which includes an ingredient not declared on the bottle.

Pinnacle Foods Group LLC said in a statement, posted to the FDA’s website, that the bottle of ranch accidentally contained Wish-Bone Blue Cheese Dressing, which includes eggs and could pose a problem for people who have allergies. Pinnacle said it had not yet received reports of illnesses from the product.

A total of 8,678 cases of the 24 oz. dressings are involved in the recall; they were produced by a contract manufacturer in April with a Best Used date of Feb. 17, 2016. Customers who have bought the recalled product can return it for a full refund.
