To ensure that a turkey is safe to eat, it must be cooked to a minimum internal temperature of 165°F (73.9°C) according to the USDA. This temperature should be measured with a meat thermometer, and it is best to check the temperature between the thigh bone and the breast for the most accurate reading. Its important to note that letting the turkey reach 165°F (73.9°C) ensures that harmful bacteria are killed, making the turkey safe to consume. Cooking the turkey to this temperature will also help to keep the meat moist and juicy. Therefore, when cooking a turkey, it is crucial to use a meat thermometer to accurately measure the internal temperature and ensure that it reaches 165°F (73.9°C) for safe consumption and optimal taste.
