Canning does have limitations, and does not preserve the food indefinitely. [14] Lactic acid fermentation also preserves food and prevents spoilage. [15] Food like meat, poultry, milk and cream should be kept out of the Danger Zone (between 4 and 60 °C (39 and 140 °F)).
Food kept after the best before date will not necessarily be harmful, but may begin to lose its optimum flavour and texture. Eggs can be a special case, since they may contain salmonella which multiplies over time; they should therefore be eaten before the best before date. In Britain, this is 21 days from when they were laid. [10]

The decomposition of food, either plant or animal, called spoilage in this context, is an important field of study within food science. Food decomposition can be slowed down by conservation. The spoilage of meat occurs, if the meat is untreated, in a matter of hours or days and results in the meat becoming unappetizing, poisonous or infectious.
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. [8]
