What is the most important rule of food storage?

Following the first in, first out (FIFO) rule is crucial in food storage primarily to ensure safety and minimize waste. This method emphasizes using older stock before newer stock, which helps reduce the risk of food spoilage and the growth of harmful bacteria. By using older items first, you ensure that foods are consumed while they are still within their safe consumption period, decreasing the likelihood of eating spoiled or expired food.

Additionally, implementing FIFO aids in inventory management, allowing for easier tracking of product freshness and avoiding excess stock of products that could go bad. It is a widely accepted best practice in food safety protocols, particularly in environments like restaurants, grocery stores, and food pantries, where maintaining the quality and safety of food is paramount.
