The method and system can include freezer and refrigeration units that are equipped with thermostats or modules for controlling and monitoring the temperatures inside the units. The thermostats may be communicatively coupled to a printer used for inventory labeling and date information. The thermostats may also include a variety of alarms that may be triggered. The method and system may provide a label that shows that any food products stored in the refrigeration and freezer units was maintained at a predetermined or desired temperature range during the storage period. The label can thus provide an indicator of “freshness” where one or more indicia may be printed thereon showing that the food product was properly stored, a temperature range during the storage period, duration of the storage period, expected shelf life of the food product, and the like.
