Some stores can be fined for selling out of date products; most if not all would have to mark such products down as wastedresulting in a financial loss.
Shelf life depends on the Expiration dating period mechanism of the specific product. Most can be influenced by several factors: Product quality is often mathematically modelled around a parameter concentration Expiration dating period a chemical compound, a microbiological index, or moisture Expiration dating period. For some foods, health issues are important in determining shelf life.
Bacterial contaminants are ubiquitous, and foods left unused too long often be Expiration dating period 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
Expiration dating period days after its sell-by date if it is refrigerated properly. However, improper storage of milk may result Expiration dating period 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.
Most medications continue to be effective and safe for a time after the expiration date. A rare exception is "Expiration dating period" case of renal tubular acidosis purportedly caused by expired tetracycline.

Shelf life is not significantly studied during drug development [ dubious — discuss ]and drug manufacturers have economic and liability incentives to specify shorter shelf lives so that consumers are encouraged to discard and repurchase products. One criticism is that the U. The SLEP and FDA signed a memorandum that scientific data could not be shared with the public, public health departments, other government agencies, and drug manufacturers. Preservatives and antioxidants may be incorporated into some food and drug products to extend their shelf life.
Shelf-life is not to be confused with service-life defined as, A general term used to quantify the average or standard life expectancy of an item or equipment while in use.
When a shelf-life item is unpacked and introduced to mission requirements, installed into intended application, or merely left in storage, placed in pre-expended bins, or held as bench stockshelf-life management stops and service life begins.
Shelf life is often specified in conjunction with a specific product, package, and distribution system. Nearly all chemical reactions can occur at normal temperatures although different reactions proceed at different rates. However most reactions are accelerated by temperatures, and the degradation of foods and pharmaceuticals is no exception.
The same applies to
Expiration dating period breakdown of many chemical explosives into more unstable compounds.
Old explosives are thus more dangerous i. Rubber products also degrade as sulphur bonds induced during vulcanization revert; this is why old rubber bands and other rubber Expiration dating period soften and get crispy, and lose their elasticity as they age. Expiration dating period, as with many rules of thumb,
Expiration dating period are many caveats and exceptions.
It is often applied in shelf life estimation, sometimes wrongly. This is mathematically incorrect if the rule was precisely accurate the required temperature increase would be about The same is true, up to a point, of the chemical reactions of living things. They are usually catalyzed by enzymes which change reaction rates, but with no variation in catalytic action, the rule of thumb is still mostly applicable.
In the case of bacteria and fungithe reactions needed to feed and reproduce speed up at higher temperatures, up to the point that the proteins and Expiration dating period compounds in their cells themselves begin to break down, or denatureso quickly that they cannot be replaced. This is why high temperatures kill bacteria and other micro-organisms: On the other hand, 'elevated' temperatures short of these result in increased growth and reproduction; if the organism is harmful, perhaps to dangerous levels.
Expiration dating period increases speed up reactions, temperature decreases reduce them. Therefore, to make explosives stable for longer periods, or to keep rubber bands springy, or to force bacteria to slow down their growth, they can be cooled. That is why shelf life is generally by temperature control: Since such storing of such goods is Expiration dating period in nature and shelf life is dependent on the temperature controlled environment, they are also referred to as cargo even when in special storage to emphasize the inherent time-temperature sensitivity matrix.
Temperature data loggers and time temperature indicators can record the temperature history of a shipment to help estimate their remaining shelf life. According to the USDA"foods kept frozen continuously are safe indefinitely.
Passive barrier packaging can often help control or extend shelf life by blocking the transmission of deleterious substances, like moisture Expiration dating period oxygen, across Expiration dating period barrier. When oxidation is the primary concern, packaging with a low oxygen transmission rate and the use of oxygen absorbers can help extend the shelf life. Produce and other products with respiration often require packaging with controlled barrier properties.
The use of a modified atmosphere in the package can extend the shelf life for some products.
According to former UK minister Hilary Bennthe use by date and sell by dates are old technologies that are outdated and should be replaced by other solutions or disposed of altogether.
