Large pots of food like soup or stew or large cuts of meats like roasts or whole poultry should be divided into small quantities for refrigeration. Foods should be covered to retain moisture and prevent them from picking up smells from other foods. Leftovers should be reheated to at least 165°F (74°C) before serving. Foods that have dangerous bacteria in them may not taste, smell, or look different. Any food that has been left out too long may be dangerous to eat, even if it looks okay.
