Food Safety and Inspection Service recommends cooking whole chicken to a safe minimum internal temperature of 73.9 °C 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 poultry to higher temperatures.
