A minimum internal temperature is important while cooking for several reasons. First, it helps to ensure that the food is cooked evenly. If the internal temperature is too low, the food may be overcooked on the outside while remaining raw on the inside. Second, a minimum internal temperature helps to kill any bacteria that may be present in the food. This is especially important when cooking meat, poultry, and fish, which can contain harmful bacteria that can cause food poisoning. Finally, cooking food to a minimum internal temperature helps to preserve its flavor and texture.
