Some stores can be fined for selling out of date products; most if not all would have to mark such products down as wastedresulting in a financial loss.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 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. Most medications continue to be effective and safe for a time after the expiration date. A rare exception is a case of renal tubular acidosis purportedly caused by expired tetracycline.

Food and Drug Administration covered over drugs, prescription and over-the-counter.

Joel Davis, a former FDA expiration-date compliance chief, said that with a handful of exceptions - notably nitroglycerin, insulin and some liquid antibiotics - most expired drugs are probably effective.

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.

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. Cold chain Nearly all chemical reactions can occur at normal temperatures although different reactions proceed at different rates.

However most reactions are accelerated by high temperatures, and the degradation of foods and pharmaceuticals is no exception.

The same applies to the 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 products soften and get crispy, and lose their elasticity as they age. However, as with many rules of thumb, there 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 other 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.

Just as temperature 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 extended by temperature control: Since such storing of such goods is temporal 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.

Online introduction services Ina variation of the online dating model emerged in the form of introduction sites, where members have to search and contact other members, who introduce them to other members whom they deem compatible.

Introduction sites differ from the traditional online dating model, and attracted a large number of users and significant investor interest. Such sites earn revenue from a mix of advertising and sale of additional options. This model also allows users to switch between free and paying status at will, with sites accepting a variety of online currencies and payment options.

Since advertising revenues are modest compared to membership fees, this model requires a large number of page views to achieve profitability. However, Sam Yagan describes dating sites as ideal advertising platforms because of the wealth of demographic data made available by users. While some sites conduct background checks on members, many do not, resulting in some uncertainty around members' identities.

For instance, some profiles may not represent real humans but rather "bait profiles" placed online by site owners to attract new paying members, or "spam profiles" created by advertisers to market services and products. Profiles created by real humans also have the potential to be problematic. For example, online dating sites may expose more female members in particular to stalkingfraudand sexual violence by online predators.

Some online dating service providers may have fraudulent membership fees or credit card charges. Furthermore, different functionalities may be offered to members who have paid or not paid for subscriptions, resulting in some confusion around who can view or contact whom.

Consolidation within the online dating industry has led to different newspapers and magazines now advertising the same website database under different names. In the UK, for example, Time Out "London Dating"The Times "Encounters"and The Daily Telegraph "Kindred Spirits"all offer differently named portals to the same service—meaning that a person who subscribes through more than one publication has unwittingly paid more than once for access to the same service.

Imbalanced gender ratios On any given dating site, the sex ratio is commonly unbalanced. When one gets into the specialty niche websites where the primary demographic is male, one typically gets a very unbalanced ratio of male to female or female to male.

There is some evidence that there may be differences in how women online rate male attractiveness as opposed to how men rate female attractiveness. Discrimination Gay rights groups have complained that certain websites that restrict their dating services to heterosexual couples are discriminating against homosexuals.
