If cooked meat and poultry look pink, does it mean that the food is not done?

The color of cooked meat and poultry is not a sure sign of its degree of doneness. For instance, hamburgers and fresh pork can remain pink even after cooking to temperatures of 160° F (71° C) or higher. The meat of smoked turkey is always pink because components within the smoke bind to the muscle pigment to form a stable pink pigment. Only by using a food thermometer can you accurately determine that meat has reached a safe internal temperature.
