The temperature of a turkey drumstick should be measured in the thickest part of the meat without touching the bone. This ensures an accurate reading to confirm the drumstick is cooked safely and thoroughly. The thickest part of the drumstick is where the temperature will be the coolest, so measuring there helps avoid undercooking. For safe cooking, the internal temperature in the thickest part of the drumstick should reach at least 165°F (74°C) according to food safety guidelines, although some cooks prefer to go higher (up to about 175-180°F) for better texture in dark meat.
