Shelf life is the recommended maximum time for which products or fresh (harvested) produce can be stored, during which the defined quality of a specified proportion of the goods remains acceptable under expected (or specified) conditions of distribution, storage and display.
One exception occurred during the 2010 Swine Flu Epidemic when the FDA authorized expired Tamiflu based on SLEP Data. [9]The US FDA is able to extend the shelf life of drugs throughout national, state, local, tribal, and territorial stockpiles through two legal means: by issuing an Emergency Use Authorization on using a drug past its expiration date (which is legally an unapproved use of a ...

Of the known chemical elements, 80 elements have at least one stable nuclide. These comprise the first 82 elements from hydrogen to lead, with the two exceptions, technetium (element 43) and promethium (element 61), that do not have any stable nuclides. As of 2024, there are total of 251 known "stable" nuclides.
Some packages contain desiccants or oxygen absorbers to help extend shelf life. Modified atmospheres [21] or controlled atmospheres are also maintained in some food packages. Keeping the contents clean, fresh, sterile [22] and safe for the duration of the intended shelf life is a primary function. A barrier is also implemented in cases where ...
