You will find calendar dates or “open dates” on perishable foods such as meat, poultry, eggs and dairy products. A “closed date” or “coded date” may appear on boxes and canned foods.
Only manufacturers know the meaning of these dates. It should be noted that dates found on products are the food manufacturer’s recommendations regarding optimal quality of the product.
