# Safe Internal Temperatures for Every Meat
The internal temperature of meat is the only reliable indicator of doneness and safety. Color, firmness, and cook time are all unreliable — a steak can be pink at 165°F or gray at 130°F depending on the cut, cooking method, and pH of the meat. A meat thermometer removes the guesswork entirely, and a good instant-read thermometer (like a Thermapen or ThermoWorks) costs $15-35 and will last for years.
Below are the science-backed temperatures you need to know, organized by protein.
Beef, Lamb, and Veal (Steaks, Roasts, and Chops)
USDA minimum safe temperature: 145°F (63°C) with a 3-minute rest.
The USDA revised their recommendation in 2011, lowering it from 160°F to 145°F for whole cuts of beef, pork, lamb, and veal. The key insight is that harmful bacteria (Salmonella, E. coli) live on the surface of whole muscle cuts, not inside them. Searing the outside to well above 160°F kills surface bacteria, which means the interior can safely be cooked to a lower temperature.
For steaks, most people prefer temperatures well below the USDA minimum:
- **Rare:** 120-125°F (49-52°C) — Cool red center. The proteins have barely begun to denature. Very soft texture.
- **Medium-rare:** 130-135°F (54-57°C) — Warm red center. This is the sweet spot for most high-quality steaks. The fat has begun to render but the proteins are still tender.
- **Medium:** 140-145°F (60-63°C) — Warm pink center. More fat rendering, slightly firmer texture.
- **Medium-well:** 150-155°F (65-68°C) — Slightly pink center. Significantly firmer. Much of the moisture has been driven out.
- **Well-done:** 160°F+ (71°C+) — No pink. Firm texture. Most of the fat has rendered and moisture has been lost.
**A critical concept: carryover cooking.** When you remove meat from heat, the temperature continues rising as heat from the exterior migrates to the cooler interior. For a thick steak, carryover can add 5-10°F. For a large roast, it can add 10-15°F. This means you should pull the meat off heat when it is 5-10°F below your target temperature and let it rest.
Ground Beef (Burgers, Meatballs, Meatloaf)
USDA minimum safe temperature: 160°F (71°C).
Ground meat has a higher minimum than whole cuts because the grinding process distributes surface bacteria throughout the interior of the meat. A pathogen that was on the surface of a whole muscle is now potentially in the center of your burger. This is why ground beef must be cooked to a higher temperature than steaks.
However, many restaurants serve burgers at 130-140°F (medium-rare to medium). They can do this more safely because they either grind their own meat from whole muscles with known sourcing, or they use irradiated beef. At home, if you grind your own beef from whole cuts (seared first) or use high-quality sourced ground beef, the risk at 145-150°F is lower — but the USDA recommendation remains 160°F. Use your own judgment based on your source and comfort level.
Poultry (Chicken, Turkey, Duck)
USDA minimum safe temperature: 165°F (74°C) for all parts.
Poultry is the one protein where there is no room for personal preference below the safety threshold. Salmonella can be present throughout poultry muscle tissue (not just on the surface), which is why the entire piece must reach 165°F. This applies to breasts, thighs, drumsticks, wings, and ground poultry.
That said, the science is more nuanced than the single 165°F number suggests. Pasteurization is a function of both temperature and time. At 165°F, Salmonella is killed almost instantaneously. But at 150°F, the same kill is achieved if held at that temperature for approximately 3 minutes. At 145°F, it takes about 8.5 minutes. This means that sous vide chicken breast cooked at 150°F for 90 minutes is just as safe as chicken cooked to 165°F — and dramatically more juicy and tender.
For traditional cooking methods where you cannot guarantee a hold time, stick with 165°F as your target.
**Dark meat (thighs, drumsticks) tastes better at 175-185°F.** Even though dark meat is safe at 165°F, the connective tissue (collagen) in thighs and drumsticks does not fully break down into gelatin until about 175°F. Chicken thighs cooked to exactly 165°F can have a rubbery, chewy texture. Cooking them to 180°F produces the tender, pull-apart texture that makes thighs and drumsticks so satisfying. This is why braised and slow-cooked dark meat tastes so much better than quickly cooked dark meat.
Pork
USDA minimum safe temperature: 145°F (63°C) with a 3-minute rest.
This was updated in 2011 (from 160°F) because modern pork is much leaner and less likely to contain Trichinella spiralis than it was decades ago. Trichinella is killed at 137°F, so 145°F provides a significant safety margin.
Pork tenderloin and pork chops are best at 140-145°F — still slightly pink in the center, juicy, and tender. Overcooking lean pork cuts is the number one reason people think they do not like pork. A pork chop cooked to 165°F is dry and tough; the same chop at 145°F is a completely different eating experience.
Pork shoulder and pork butt (for pulled pork) are a different story. These cuts are packed with collagen and connective tissue that does not break down until 195-205°F. At 145°F they are safe to eat but tough and chewy. At 203°F, the collagen has converted to gelatin and the meat falls apart into tender, shredable strands. The same principle applies to pork ribs — low and slow to 195-205°F for the best texture.
Fish and Seafood
USDA minimum safe temperature: 145°F (63°C).
Most fish is considered done (by chefs, not just by food safety standards) at 130-140°F, depending on the species:
- **Salmon:** 125-130°F for medium-rare (translucent center), 140°F for well-done (opaque throughout). Many people prefer salmon at 125°F because the fat has rendered but the protein has not yet become dry and flaky.
- **Tuna:** 110-115°F for rare (seared outside, raw inside — the standard for ahi tuna). Cooking tuna to 145°F produces a dry, gray product that misses the point of the fish.
- **White fish (cod, halibut, sea bass):** 130-140°F. These lean fish dry out quickly above 140°F.
- **Shrimp:** Until they are pink, opaque, and curled into a loose C-shape. Overcooked shrimp curl into tight O-shapes and become rubbery.
Sushi-grade fish is typically flash-frozen to kill parasites and is safe to eat raw, but this is a separate category from cooking to temperature.
The Resting Rule
Resting meat after cooking is not optional — it is a critical step that affects both safety and quality. During cooking, the muscle fibers contract and push moisture toward the center of the cut. If you slice immediately, that concentrated moisture pours out onto the cutting board instead of staying in the meat. Resting allows the fibers to relax and the moisture to redistribute evenly.
General resting guidelines: - **Steaks (1-1.5 inches):** 5-8 minutes - **Thick steaks (2+ inches):** 8-12 minutes - **Roasts (3+ pounds):** 15-20 minutes, tented loosely with foil - **Whole turkey or large roast:** 20-30 minutes minimum
Tenting with foil slows heat loss but also traps steam, which can soften a seared crust. For steaks where crust matters, rest uncovered or on a wire rack.
How a Thermometer Actually Works in Practice
Insert the probe into the thickest part of the meat, away from bone (bone conducts heat differently and can give false readings). For irregular cuts, check multiple spots and use the lowest reading as your actual temperature. For thin cuts like chicken breasts, insert the probe from the side into the geometric center.
Digital instant-read thermometers give a reading in 2-3 seconds. Dial thermometers take 15-30 seconds and are less accurate. Oven-safe probe thermometers that stay in the meat during cooking are ideal for roasts and whole birds because you can monitor temperature continuously without opening the oven.
ButcherIQ can help you identify the right temperature targets for specific cuts — snap a photo of what you are cooking and get recommendations for temperature, rest time, and technique based on the cut, thickness, and your preferred doneness. The app accounts for the specific characteristics of the cut so you get a more precise target than a generic chart.
The Bottom Line
A meat thermometer is the most underused tool in the home kitchen. It costs less than a single steak and eliminates overcooking — which, in terms of wasted money on ruined meat, pays for itself in a few uses. Learn the key temperatures for your most-cooked proteins, understand that carryover cooking adds 5-10°F, and rest your meat properly. Everything else is refinement.
