Shelf-Life: What Do Expiration Dates Really Mean?

While regular milk expires within about a week or sooner, organic milk lasts much longer—as long as a month. So what is it about organic milk that makes it stay fresh so long?

All “organic” means is that the farm the milk comes from does not use antibiotics to fight infections in cows or hormones to stimulate more milk production.

According to food safety specialist Brian A. Nummer, Ph.D., unopened home canned foods have a shelf life of one year to two years while commercially canned foods should be able to retain their best quality until the expiration code date on the can.

In most food stores, shelf life is maximized by using stock rotation , which involves moving products with the earliest sell by date to the front of the shelf, meaning that most shoppers will pick them up first and so getting them out of the store. This is important, as some stores can be fined for selling out of date products, and most if not all will have to mark such products down as wasted , leading to a loss of profit.

Shelf life is most 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 acquire substantial amounts of bacterial colonies and become dangerous to eat, leading to food poisoning. However, the shelf life itself is not an accurate indicator to the food safety. For example, pasteurized milk can remain fresh for five days after its sell-by date if it is refrigerated properly.

In contrast, if milk already has harmful bacteria, the use-by dates become irrelevant. Most medications are potent and safe after the expiration date. A rare exception is a case of renal tubular acidosis purportedly caused by expired tetracycline.
