First Expired, First Out (FEFO) is a term used in field inventory management to describe a way of dealing with the logistics of products that have a limited shelf life.
Foods and pharmaceutical drugs can be sold at a discounted price, and, near the expiration date, they can be destinated to humanitarian aids to the neighbours or to the more distant foreign countries.
The First expired, first out logic is a type of stock rotation that enable organizations to get a distribution process optimization, able to minimize the waste generation of finished and yet marketable products.
[1] Perishable goods (like foods and drugs) lose all their use value after the expiration date and can't be bought nor sold as their commercial price and value falls to zero.
But however, it doesn't concern about single items data, in order to become a database (a bank) of such perishable expiring products for humanitarian and charitative purposes.
