On. Jan. 22, the U.S. Food and Drug Administration (FDA) elevated a recall of some Cal Yee Farm chocolate products to its most serious level, Class I, for some products — Dark Chocolate Almonds, Dark Chocolate Apricots and Dark Chocolate Walnuts — that contain milk not listed in the ingredients, according to the New York Post.

Chocolate- and yogurt-covered snacks made by Cal Yee Farm LLC could cause allergies not indicated on the label, the FDA warns.
