What is the correct temperature of a whole turkey when thermometer placed in breast?

The safe internal temperature for a whole turkey, when measured in the thickest part of the breast, is 165°F (74°C).

It's important to note that the turkey should be cooked to this temperature throughout, not just in the breast. You should also check the temperature in the thigh to ensure it has reached 165°F as well.

Here are some additional tips:

* Use a meat thermometer: Always use a meat thermometer to ensure your turkey is cooked to the correct temperature.

* Don't rely on visual cues: A turkey may appear cooked even if it isn't. Don't rely on color or juices to determine doneness.

* Let the turkey rest: After cooking, let the turkey rest for at least 20 minutes before carving. This will allow the juices to redistribute, resulting in a moister bird.
