Poultry requires the highest internal cooking temperature of any food: 165°F (73.9°C). That applies to all chicken, turkey, and other poultry, whether you’re cooking a whole bird, individual parts, or ground poultry. No other common food category has a higher minimum safe temperature.
The Complete Temperature Hierarchy
Not all proteins carry the same risk, so safe cooking temperatures vary. Here’s how the major food categories stack up, from highest to lowest:
- Poultry (165°F / 73.9°C): Whole birds, breasts, legs, thighs, wings, ground poultry, giblets, and stuffing cooked inside the bird.
- Leftovers and casseroles (165°F / 73.9°C): Any previously cooked food being reheated, plus meat or poultry casseroles.
- Ground meats (160°F / 71.1°C): Hamburgers, meatloaf, and any ground beef, pork, lamb, or veal.
- Egg dishes (160°F / 71.1°C): Quiche, egg casseroles, and any cooked egg mixture.
- Whole cuts of beef, pork, lamb, and veal (145°F / 62.8°C): Steaks, chops, and roasts, with a three-minute rest time after removing from heat.
- Fish (145°F / 62.8°C): Finfish should be opaque and flake easily with a fork.
Why Poultry Tops the List
Poultry is especially prone to harboring harmful bacteria like Salmonella throughout the meat, not just on the surface. Unlike a beef steak, where bacteria typically sit on the outside and get killed the moment the surface hits a hot pan, chicken and turkey can carry pathogens deep in the tissue. That’s why every part of the bird needs to reach 165°F: at that temperature, dangerous bacteria are destroyed almost instantly.
This is also why ground poultry sits at 165°F while ground beef only needs 160°F. Grinding any meat mixes surface bacteria throughout, raising the stakes compared to whole cuts. But because poultry starts with a higher bacterial risk, ground chicken and ground turkey still need that extra five degrees.
Why Ground Meat Needs More Heat Than Steak
A common source of confusion is why a beef steak is safe at 145°F while a hamburger needs 160°F. The answer comes down to what grinding does. When beef is ground, any bacteria on the surface get folded into the center of the patty, where they’re protected from heat. A whole steak only needs its exterior seared because that’s where the contamination lives.
Color is not a reliable guide here. Ground beef can turn brown well before it reaches 160°F, and some patties stay pink even after they’re fully safe. The USDA is clear on this: visual cues like meat color or juice color are not accurate indicators of doneness. A food thermometer is the only way to know.
Leftovers and Reheating
Reheated leftovers share the top spot with poultry at 165°F, regardless of what the original food was. Even if you’re reheating a pork chop that only needed 145°F the first time around, it needs to hit 165°F when you warm it up. Bacteria can multiply on cooked food during storage, so the higher reheating temperature provides an extra margin of safety.
This applies whether you’re reheating in an oven, on a stovetop, or in a microwave. If you use a microwave, keep heating until the thermometer reads 165°F throughout, since microwaves heat unevenly and can leave cold spots where bacteria survive.
Stuffing Inside a Bird
Stuffing cooked inside a turkey or chicken must also reach 165°F at its center. This is trickier than it sounds, because the stuffing sits in the cavity where heat penetrates last. It’s possible for the bird’s breast and thigh to hit 165°F while the stuffing is still dangerously undercooked in the middle. If both haven’t reached temperature, the whole thing needs to go back in the oven.
For this reason, the USDA recommends cooking stuffing separately for the most consistent results. If you do stuff the bird, check the center of the stuffing with a thermometer independently from the meat.
Where to Place the Thermometer
Getting an accurate reading depends on where you insert the probe. For a whole chicken or turkey, check three spots: the thickest part of the breast, the innermost part of the thigh, and the innermost part of the wing. Avoid touching bone, gristle, or the pan, all of which can give a falsely high reading.
For breasts and ground poultry patties, insert the thermometer from the side rather than the top. This positions the sensor in the center of the thickest section and gives a more accurate reading. Every spot you check should read at least 165°F before the bird is safe to eat.
