The following rules of safe food storage have two purposes:
To prevent contamination of foods.
To prevent growth of bacteria that may already be in foods.
Temperature control is an important part of food storage. Perishable foods must be kept out of the Food Danger Zone—40° to 140°F (4° to 60°C)—as much as possible, because these temperatures support bacterial growth. See Figure 2.1 for a chart of important temperatures.
