"Closed or coded dates" are a series of letters and/or numbers and typically appear on shelf-stable products such as cans and boxes of food. There are no uniform or universally accepted descriptions used on food labels for open dating in the United States.As a result, there are a wide variety of phrases used on labels to describe quality dates. One source of food waste arises from consumers or retailers throwing away wholesome food because of confusion about the meaning of dates displayed on the label.To reduce consumer confusion and wasted food, FSIS recommends that food manufacturers and retailers that apply product dating use a "Best if Used By" date.
There are two types of bacteria that can be found on food: pathogenic bacteria, which cause foodborne illness, and spoilage bacteria, which cause foods to deteriorate and develop unpleasant characteristics such as an undesirable taste or odor making the food not wholesome, but do not cause illness.When spoilage bacteria have nutrients (food), moisture, time, and favorable temperatures, these conditions will allow the bacteria to grow rapidly and affect the quality of the food.The quality of perishable products may deteriorate after the date passes, however, such products should still be safe if handled properly.Consumers must evaluate the quality of the product prior to its consumption to determine if the product shows signs of spoilage. Open dating is found on most foods including meat, poultry, egg and dairy products.[Top of Page] Dating Infant Formula Federal regulations require a "Use-By" date on the product label of infant formula under inspection of the U. Formula must maintain an acceptable quality to pass through an ordinary bottle nipple.
The "Use-By" date is selected by the manufacturer, packer or distributor of the product on the basis of product analysis throughout its shelf life, tests, or other information.
Foods not exhibiting signs of spoilage should be wholesome and may be sold, purchased, donated and consumed beyond the labeled "Best if Used By" date.
[Top of Page] Safety After Date Passes With an exception of infant formula (described below), if the date passes during home storage, a product should still be safe and wholesome if handled properly until the time spoilage is evident (Chill Refrigerate Promptly).
Microorganisms such as molds, yeasts, and bacteria can multiply and cause food to spoil.
Viruses are not capable of growing in food and do not cause spoilage.
Food spoilage can occur much faster if it is not stored or handled properly.
