However, improper storage of milk may result in bacterial contamination or spoilage before the expiration date.

The expiration date of pharmaceuticals specifies the date the manufacturer guarantees the full potency and safety of a drug.

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.

Some companies use induction sealing and vacuum/oxygen-barrier pouches to assist in the extension of the shelf life of their products where oxygen causes the loss.

The Do D Shelf-Life Program defines shelf-life as The total period of time beginning with the date of manufacture, date of cure (for elastomeric and rubber products only), date of assembly, or date of pack (subsistence only), and terminated by the date by which an item must be used (expiration date) or subjected to inspection, test, restoration, or disposal action; or after inspection/laboratory test/restorative action that an item may remain in the combined wholesale (including manufacture's) and retail storage systems and still be suitable for issue or use by the end user.

For some foods, health issues are important in determining shelf life.

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.Most medications continue to be effective and safe for a time after the expiration date. Food and Drug Administration covered over 100 drugs, prescription and over-the-counter.A rare exception is a case of renal tubular acidosis purportedly caused by expired tetracycline. The study showed that about 90% of them were safe and effective as long as 15 years past their expiration dates.There is a widespread impression, for instance in industry, that "triple time" can be simulated in practice by increasing the temperature by 15 °C (27 °F), e.g., storing a product for one month at 35 °C (95 °F) simulates three months at 20 °C (68 °F).This is mathematically incorrect (if the rule was precisely accurate the required temperature increase would be about 15.8 °C (28.4 °F)), and in any case the rule is only a rough approximation and cannot always be relied on.Some stores can be fined for selling out of date products; most if not all would have to mark such products down as wasted, resulting in a financial loss.
