The treat contains almonds, hazelnut and soya not listed on the label.
The Food Standards Agency website said: “Waitrose & Partners is recalling Waitrose No.1 Dominican Republic Milk Chocolate 49 percent because some products contain almonds, hazelnuts (nuts) and soya which are not mentioned on the label.
“Due to a packaging error, some products contain Waitrose No.1 Orange & Almond Chocolate instead.
“This means the product is a possible health risk for anyone with an allergy to almonds, hazelnuts (nuts) and/or soya.”
