Safe food handling helps protect you from food-borne illness. Food must not only be cooked to the correct temperature, but also stored within specific temperature ranges and for limited periods of time to prevent harmful bacteria from growing. When stored properly, turkey soup will stay fresh for several days. If you're in doubt about it's freshness, though, chuck it immediately, regardless of how long the soup's been refrigerated.
Length of Storage
According to the U.S. Department of Agriculture, soups containing cooked turkey or other poultry may be kept in the refrigerator for three to four days. When using leftovers, you should be aware of the smell and taste of the soup. If the soup smells or tastes different after three days or fewer, you should not consume it.
Before putting leftover turkey soup in the refrigerator, divide it into smaller, shallow containers and cover them completely. Place the containers into a refrigerator that maintains a temperature of 40 degrees Fahrenheit or below. Leave space between the containers to allow for air circulation and efficient cooling.
When reheating turkey soup, bring the soup to a full boil in a saucepan or in the microwave. According to the USDA, the soup must reach a temperature of at least 165 degrees Fahrenheit to be safe for consumption.
