Nothing can shatter those visions of a Norman Rockwell Thanksgiving faster than illness caused by an improperly roasted turkey. Here are some tips from the U.S. Department of Agriculture to keep your holiday dinner wholesome:
• For optimum safety, stuffing a turkey is not recommended. For more even cooking, it is recommended you cook your stuffing outside the bird in a casserole.
Use a food thermometer to check the internal temperature of the stuffing. The stuffing must reach a safe minimum internal temperature of 165 °F.
• If you choose to stuff your turkey, the ingredients can be prepared ahead of time; however, keep wet and dry ingredients separate. Chill all of the wet ingredients (butter/margarine, cooked celery and onions, broth, etc.).
Mix wet and dry ingredients just before filling the turkey cavities. Fill the cavities loosely. Cook the turkey immediately. Use a food thermometer to make sure the center of the stuffing reaches a safe minimum internal temperature of 165 °F.
• A whole turkey is safe when cooked to a minimum internal temperature of 165 °F as measured with a food thermometer. Check the internal temperature in the innermost part of the thigh and wing and the thickest part of the breast.
For reasons of personal preference, consumers may choose to cook turkey to higher temperatures.
• If your turkey has a "pop-up" temperature indicator, it is recommended that you also check the internal temperature of the turkey in the innermost part of the thigh and wing and the thickest part of the breast with a food thermometer. The minimum internal temperature should reach 165 °F for safety.
