<p>A method and device for ensuring the consumption of perishable food items before a safe storage lifetime for the items has elapsed. A base unit (10) is mounted near or removably attached to a food storage location such as a refrigerator and allows identification and timing of the stored food items. When an item is placed into the storage location, its name (20) and storage lifetime (27) are recorded on the base unit. For ease of later location the item may be optionally stored inside of food storage containers color coded (26) to the base unit. A numeric display (28) is provided so that the length of time an item has been stored can be determined and compared with the safe storage lifetime. The base unit also provides an electronic warning display for each stored item. The warning display gives visual warning when the elapsed time approaches and then reaches the safe storage time.</p> |
