HP Hood, the maker of Almond Breeze almond milk, is recalling more than 145,000 cartons of its vanilla-flavored beverage because the product may contain actual dairy milk, the Daily Herald reports.

Any product that does not explicitly state that it contains an allergen—in this case, milk—is subject to recall. In fact, undeclared allergens are the most common reason given for food recalls in the U.S. The almond milk, which was shipped to stores in 28 states, could potentially pose a danger to people who have dairy allergies or are lactose intolerant. Otherwise, it’s safe to consume, according to the FDA.

The only products affected are Almond Breeze's refrigerated vanilla almond milk cartons with a use-by date of September 2 and a Universal Product Code of 41570 0562 on the side of the carton.

Consumers who have already purchased the affected product may return it for a full refund by filling out a form on Blue Diamond’s website.
