An expiration date or expiry date is a previously determined date after which something should no longer be used, either by operation of law or by exceeding the anticipated shelf life for perishable goods. Expiration dates are applied to selected food products and to some other manufactured products like infant car seats where the age of the product may impact its safe use. Arbitrary expiration dates are also commonly applied by companies to product coupons , promotional offers and credit cards. In these contexts, the expiration date is chosen for business reasons or to provide some security function rather than any product safety concern. The legal definition and usage of the term expiration date will vary between countries and products. Best before or best by dates appear on a wide range of frozen, dried, tinned and other foods. These dates are only advisory and refer to the quality of the product, in contrast with use by dates, which indicate that the product may no longer be safe to consume after the specified date. Eggs are a special case, since they may contain salmonella which multiplies over time; they should therefore be eaten before the best before date, which is, in the USA, a maximum of 45 days after the eggs are packed.

New technologies to predict spoilage time could slash the massive waste between farm and fork. In August , a can of Great Value peas joined the nonperishables in my pantry, one of several panic purchases as Hurricane Irene barreled toward my home on the northeast US coast. But the emergency passed, and the can, with its unassuming blue-on-white outline font, remains on my shelf seven years later.

Can canned peas go bad? How would I know if they had? Such confusion, common in many a cupboard, drives an enormous amount of food waste: About 40 percent of food in the US gets trashed, often due to belief that a gone-by date on a package means the food is not safe. Many countries have simplified food packaging to carry a use-by date for when a product might actually go bad or a best-before date reflecting when it might start to become less palatable.

US manufacturing groups recently announced voluntary guidelines to adopt such nomenclature. But this may not help much to reduce food waste. A better solution — and more effective waste reduction — could come from a flurry of progress in the science of determining and tracking shelf life , say Ross and other experts. Driven by advances in informatics, sensor technologies and chemical analysis, such improvements could lead to more accurate date stamps or one day even render them moot. Researchers have developed a thin, transparent sensor that could one day be used commercially to detect pathogens such as E.

Activation happens when the probes come into contact with the pathogen or with certain molecules it secretes. The fluorescence could then be scanned by a hand-held device or a smartphone to detect the bacterium without opening the package.

One principle is that the shelf life is a function of the distribution conditions and can be looked at as the percentage of consumers a manufacturer is willing to displease. Thus, one purpose of an open date is to give consumers enough time to purchase a food product and store it at home for a reasonable period of time before the product reaches the end of shelf-life in terms of some degree of quality change that is still acceptable.

Since the s, food consumers across the globe have demanded shelf life dates on food packages that help them decide both purchase and consumption.
