What does "first in, first out" (FIFO) mean in the context of food storage?

In the context of food storage, "first in, first out" (FIFO) refers to the method where the oldest stock is used first. This practice is essential in managing food inventory effectively, as it helps to minimize waste and ensure that food items are consumed while they are still fresh and safe to eat.

By utilizing the oldest stock first, you reduce the risk of spoilage and ensure that the food maintains its quality and safety for consumption. This method is critical in maintaining food safety standards and helps businesses manage their inventory efficiently, thus reducing potential losses caused by expired products.

Other methods, such as using the last stock first or keeping stock indefinitely, do not adhere to food safety guidelines and can lead to issues with food quality and safety, which makes them less desirable for managing food inventory.
