The O/U certifies Cappiello Fresh Mozzarella Cheese. The certified cheese bears the “O/UD” (dairy) symbol and states that it is from Schenectady plant number #36-3893 on the front of the label. For about 2 months, Cappiello will make a non-certified Fresh Mozzarella Cheese at another facility. The non-Certified cheese does NOT include Schenectady, #36-3893 and the OUD symbol on the label. Consumers should be careful to look for the O/U symbol before purchasing this product.
