What is a fundamental requirement for food storage?

Labeling containers with the date received is essential because it helps ensure food safety and proper inventory management. By marking the date when items are received, employees can keep track of the shelf life and prioritize using older stock first, following the "first in, first out" (FIFO) principle. This practice helps to minimize waste, prevent the use of spoiled foods, and maintain quality standards. Proper labeling also facilitates better organization in storage areas, making it easier to identify what items need to be used or discarded based on their freshness and safety.
