Claim:
1. A system for tracking the shelf life status of one or more perishables removed from and/or returned to a container, containing a plurality of perishables, said system comprising: an ID label associated with each of said plurality of perishables; one or more sensors in the container operative at periodic sensing periods to sense the temperature of each of said plurality of perishables in a container; a tracking device, communicatively coupled to said container operative to calculate and/or record at each periodic sensing the shelf life status of said plurality of perishables in the container using the sensed temperature and responsive to the movement of a perishable exiting said container to calculate and/or record the exit shelf life status for the associated perishable based upon the exit temperature of the perishable, the elapsed time since last sensing and spoilage characteristics of said perishable; said perishable being moved to a position where there is no temperature monitoring; said tracking device being operative to sense the temperature of said perishable entering a container, calculate the shelf life, using the temperature sensed and the spoilage characteristics of the perishable for the time that the perishable was not temperature monitored, and subtract an away freshness shelf life status, which is defined by the time the perishable was not temperature monitored, from said exiting shelf life status, wherein the difference identifies the amount of remaining shelf life if greater than zero.
