Background[ edit ] Shelf life is the recommended maximum time for which products or fresh harvested produce can be stored, during which the defined quality of a specified proportion of the goods remains acceptable under expected or specified conditions of distribution, storage and display. If the cans look okay, they are safe to use. Discard cans that are dented, rusted, or swollen.

Most food is still edible after the expiration date. In most food stores, waste is minimized by using stock rotation , which involves moving products with the earliest sell by date from the warehouse to the sales area, and then to the front of the shelf, so that most shoppers will pick them up first and thus they are likely to be sold before the end of their shelf life. This is important, as consumers enjoy fresher goods, and furthermore some stores can be fined for selling out of date products; most if not all would have to mark such products down as wasted , resulting in a financial loss.
Shelf life depends on the degradation mechanism of the specific product. Most can be influenced by several factors: Product quality is often mathematically modelled around a parameter concentration of a chemical compound, a microbiological index, or moisture content. Bacterial contaminants are ubiquitous, and foods left unused too long will often be contaminated by substantial amounts of bacterial colonies and become dangerous to eat, leading to food poisoning.
However, shelf life alone is not an accurate indicator of how long the food can safely be stored. For example, pasteurized milk can remain fresh for five days after its sell-by date if it is refrigerated properly. However, improper storage of milk may result in bacterial contamination or spoilage before the expiration date.

The results showed that about 90 percent of the drugs were still effective far past their expiration dates. Fifteen years ago, the U. Sitting on a one billion dollar stockpile of drugs and facing the daunting process of destroying and replacing its supply every two to three years, the military began a testing program to see if it could extend the life of its inventory.
The testing, conducted by the U. Food and Drug Administration, ultimately covered more than drugs, prescription and over-the-counter. The results, never before reported, show that about 90 percent of them were safe and effective far past their original expiration date, at least one for 15 years past it. In light of these results, a former director of the testing program, Francis Flaherty, says he has concluded that expiration dates put on by manufacturers typically have no bearing on whether a drug is usable for longer.
Flaherty notes that a drug maker is required to prove only that a drug is still good on whatever expiration date the company chooses to set. The expiration date doesn’t mean, or even suggest, that the drug will stop being effective after that, nor that it will become harmful.
