Rotation of food storage in order to use the oldest inventory first.

• A. Flow of Food
• B. FAT TOM
• C. First In First Out
• D. FIFO (First In First Out)

Answer: (D)

Using oldest stock first is applying the FIFO method. FIFO, or First In, First Out, means you rotate stock so items received earlier are used before newer ones. This helps keep perishable foods within safe time frames and reduces waste by preventing items from sitting too long. In practice, label items on receipt, place older products in front or at the front of storage, and move newer stock to the back so the oldest are used first. Flow of Food describes the path food takes through a operation and doesn’t address rotation; FAT TOM lists factors that affect microbial growth, not inventory management. The term that captures this rotation practice is FIFO.
