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.

An open date does not supersede a use-by dateif shown, which should still be followed. An expiration date on food differs from a best-before date.
According to the Canadian Food Inspection Agency "Expiration dates are required only on certain foods that have strict compositional and nutritional specifications which might not be met after the expiration date.
In Canada expiration dates must be used on the following food items list and comments copied from CFIA website :. The concern is that after the expiration date has passed, the food may not have the same nutrient content as specified on the packaging and for the listed regulated products, the nutritional content is quite important. The CFIA recommends that food should be discarded and should not be bought, sold or eaten beyond the stated expiration date. This contrasts with a best before date which is an indication of how long properly stored prepackaged food is expected to retain its "freshness, taste, nutritional value, or any other qualities claimed by the manufacturer.

Non-food items may also carry an expiration date. For example, in Canada, all children are required to be secured in an infant car seat while in a motor vehicle that is in motion.
Users are required by law to follow manufacturer's directions. There is no specific law that requires an expiration date, but all Transport Canada approved car seats sold in Canada carry a manufacturer applied expiration date that ranges between 6 and 9 years from date of manufacture.
Apr 01, Sec. Expiration dating. (a) To assure that a drug product meets applicable standards of identity, strength, quality, and purity at the time of use, it shall bear an expiration date. Mar 09, IVD products that are expiration dated will have the expiration date found on the product labels. When dating is indicated by month and year only and no specific date is otherwise stated on the label or elsewhere, the product is expected to meet specifications until the last day of the month. Recommended Retest Dated Products. § Expiration dating. (a) To assure that a drug product meets applicable standards of identity, strength, quality, and purity at the time of use, it shall bear an expiration date determined by appropriate stability testing described in §
The rationale is that car seats are subjected to heat, cold, sun exposure, abuse by the children, and long term storage between children, all of which can degrade the structure and function of the car seat and fail in a crash.
Further, beyond the expiration date the manufacturer will no longer be monitoring the safety of the seat through testing.
Transport Canada advises to destroy an expired car seat and dispose of it at a landfill or recycling facility, and never to give an expired seat to someone else or to charity. With the exception of infant formula, the laws that the Food and Drug Administration FDA administers do not preclude the sale of food that is past the expiration date indicated on the label. FDA does not require food firms to place "expired by", "use by" or "best before" dates on food products. This information is entirely at the discretion of the manufacturer.
Most expiration dates are used as guidelines based on normal and expected handling and exposure to temperature. Use prior to the expiration date does not guarantee the safety of a food or drug, and a product is not necessarily dangerous or ineffective after the expiration date.
If the cans look okay, they are safe to use. Discard cans that are dented, rusted, or swollen.

High-acid canned foods tomatoes, fruits will keep their best quality for 12 to 18 months; low-acid canned foods meats, vegetables for 2 to 5 years". Most food is still edible after the expiration date. In most food stores, waste is minimized by using stock rotationwhich 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.

Keep in mind that most products have a month shelf life. The best-by date is meant for the consumer.
EXPIRATION DATING (21 CFR ) A. Absence of an Expiration Date The absence of an expiration date on any drug product packaged after September 29, , except for those drugs specifically.
Rather, it just means that the item will be at its freshest or most effective before that date. If it smells good, looks good, and has been properly stored, it should still be safe to eat.
For example, a lotion might become lumpy or a liquid foundation might become tacky. Most over-the-counter medications are effective for as long as 10 years past the expiration date.
You can consume food items safely for at least days past the sell-by date, but most retailers will be ready to move the stock off of their shelves to make way for new shipments. For food items, it means to be on higher alert when you open the product, as it could have started to decay or go stale.
God! Well dating with an expiry date know, how necessary
Generally, the placing of three initial batches into the long term stability program is considered minimal to assure batch uniformity for establishing an expiration date. Since a dosage form is a complex unit and there are continued variables in the production process, such as change in personnel, raw material lots and suppliers, and equipment, it is imperative that stability studies are not limited only to initial production batches but a portion of annual production batches be the subject of an ongoing stability program.
When accelerated stability studies are performed, one batch may be adequate in order to establish a tentative expiration date. This is acceptable since it is not the purpose of an accelerated test to determine batch uniformity but rather to test for kinetic degradation.
The use of accelerated testing data to establish a tentative expiration dating period of greater than three years is discouraged when it is based solely on accelerated data. Combining data compiled at room temperature and at accelerated temperature is possible to justify an expiration dating period of over two years.
This can be done, as an example, by taking a sample product that has been at room temperature for one year and subjecting that sample to accelerated temperature conditions. The expiration dating period used would then be the sum of that justified individually at each storage condition.
Pity, dating with an expiry date rather
We do not believe it is reasonable to perform accelerated testing at very high temperatures for a very short time and expect to extrapolate results to a very long expiration dating period since the actual mechanism of degradation at high temperature may be different than at room temperature. It is commonly recommended that stability testing be performed initially, than every three months for the first year, then every six months for the second year, and then annually thereafter.
However, more frequent testing near the end of the anticipated expiration date is often likely to give better information about the actual stability of the finished product.
Nonetheless, testing at least annually is considered minimal for compliance with CGMPs. Some firms have chosen, for economical purposes, random dates to test all stability samples of a given product. As long as there is at least one test performed annually, this approach can be quite satisfactory. If a product was stored under controlled conditions, those actual conditions temperature and humidity should be recorded.
Merely stating that a product was stored at room temperature is not sufficient for purposes of determining stability. A product stored for stability at or near 15 C may have quite a different quality profile at its expiration date than a product stored at or near 30 C.
Based on published information, it appears that C is a reasonable reference for thermal exposure at room temperature. Stability studies should be conducted on product stored under normal storage conditions or, preferably, under exaggerated conditions.

Products liable to degradation by light or moisture should be stored either in a lighted area or under conditions of high humidity unless it can be demonstrated that the packaging will prevent deterioration by that condition of interest. For example, a product liable to degrade by light need not be stored in a lit area if it is normally packaged and stored for use in an opaque container.
