Dark meat has about 9% fat, 33% more than white meat. So, it tastes and feels best at about 170°F (76.7°C). White meat is very lean, about 6%, and it dries out quickly if it is overcooked. It is at its best texture and juiciness at about 155°F (68.3°C). But that’s 10°F (5.7°C) below the USDA recommendation and the risk is too great at that temp. So I will advise you to cook it to 160°F (71.1°C) and let the temp rise to 165°F (74°C) while it moves from cooker to carving. More on this below.
USDA wants to keep things simple for us in order to keep us safe. Admirable! What USDA doesn’t tell you is that microbes start croaking at about 130°F (54.4°C). The hotter the food gets, the faster the pathogens die. You can pasteurize your turkey at 130°F (54.4°C) in 2 hours or at 165°F (74°C) in 2 seconds, hence the USDA recommended minimum of 165°F (74°C). What the USDA doesn’t tell you is that you can kill them all if you heat the bird to 160°F (71.1°C) for 7 seconds, 155°F (68.3°C) for 23 seconds, or 145°F (62.8°C) for about 4 minutes.
