Abstract

A method of tracking and monitoring the temperature of a food product from point of origin until it is removed from the display case by the consumer for immediate transport to the point of sale. As a plurality of food products are delivered to a store and put into a storage facility, a sensor is associated with a group of food products. The sensor is adapted to simulate the temperatures of the associated products using “learning algorithms”. As the food products are removed from storage to the preparation area, the sensor is also moved to the preparation area. During preparation, the temperature data may be added to the product label. Then, the product is loaded into a display fixture. The display fixture has a network interface that activates a cooling system for the display fixture upon activation by the sensor.
