La Choy Bean Sprouts, Chop Suey Vegetables and Fancy Mixed Chinese Vegetables in 14 oz. cans are produced at a non-Kosher facility and are NOT Kosher. Some 14 oz. cans, with lot numbers beginning with 21019, were mistakenly labeled with the O/K symbol. All other sizes, when bearing the O/K symbol are correctly labeled and Kosher certified. This includes #10 cans (102 oz.) of all 3 items and 28 oz. cans of Chop Suey Vegetables.
