The only reliable way to know if meat is still raw or undercooked is to check its internal temperature with a food thermometer. Color, texture, and juice clarity can all mislead you. Meat can look brown and done on the outside while still being dangerously undercooked inside, and some fully cooked meat stays pink throughout. Understanding both the visual cues and their limitations will help you stay safe.
Why Color Alone Can’t Tell You
Most people rely on color to judge whether meat is cooked: red means raw, pink means underway, brown means done. This works as a rough guide for whole cuts of beef or pork, but it falls apart with ground meat and poultry. A Kansas State University study found that more than 25 percent of fresh ground beef patties turned brown before reaching a safe internal temperature. Some patties looked fully done at just 131°F, nearly 30 degrees below the safe threshold of 160°F.
The reverse problem is equally common. Ground beef with a higher pH (around 6.0 or above) can stay pink even after hitting 160°F or higher. Low-fat patties are especially prone to this. So a burger that looks pink in the middle might be perfectly safe, while one that looks brown throughout might not be. The USDA’s own assessment is blunt: color and texture indicators are not reliable for ground meat.
With whole muscle cuts like steaks and chops, color is somewhat more predictable. Beef gets less red as internal temperature climbs, with steaks cooked to about 150°F showing noticeably less pink than those at 130°F. But even here, factors like the animal’s age, diet, and the meat’s pH can shift the color at any given temperature.
Cured and Treated Meats Stay Pink on Purpose
If you’ve ever cut into a fully cooked ham or hot dog and wondered why it’s still pink, that’s by design. Curing salts contain nitrites, which convert to nitric oxide inside the meat. Nitric oxide bonds with the pigment in muscle tissue and creates a stable reddish-pink color that actually intensifies during cooking rather than fading. This is why deli ham, bacon, and corned beef look pink no matter how long you cook them. The pink color in these products is not a sign of rawness.
The Clear Juices Myth
A widespread kitchen rule says chicken is done when the juices run clear. This is unreliable in both directions. Poultry with lower muscle pH can produce clear juices at temperatures as low as 150°F, which is 15 degrees below the safe minimum for chicken. On the flip side, perfectly safe chicken can release slightly pink juices due to pigment from bone marrow, especially in younger birds. If you’re poking chicken to check for clear liquid, you’re using a method that can both overcook safe meat and undercook dangerous meat.
Pink meat near the bone in cooked chicken is another common source of worry. Bone marrow pigment can leach into surrounding tissue during cooking, tinting it pink even when the meat has reached a safe temperature. This is especially common in younger chickens and in thighs or drumsticks.
What Raw Meat Actually Looks Like
If you’re simply trying to identify whether a piece of meat has been cooked at all, there are some consistent visual and textural differences between raw and cooked meat:
- Beef and lamb: Raw cuts are bright red to deep purple on the surface (or brownish-red if they’ve been exposed to air for a while). The interior is wet, glossy, and soft. Cooked beef firms up considerably and shifts from red toward brown or gray, depending on doneness.
- Pork: Raw pork is pale pink and somewhat translucent, with a soft, slightly slippery texture. Cooked pork turns opaque and lighter in color, though it often retains a faint pink tinge even when fully safe.
- Poultry: Raw chicken and turkey are glossy, pale pink (white meat) or darker pink-red (dark meat), and very soft to the touch. Cooked poultry turns opaque white or light brown and has a firmer, drier texture.
- Fish: Raw fish is translucent or semi-translucent, with a jelly-like give when pressed. Cooked fish turns opaque white (for white fish) and flakes apart easily with a fork.
These visual cues tell you whether cooking has happened, but they don’t tell you whether cooking has happened enough. That distinction matters.
Safe Internal Temperatures by Meat Type
The USDA sets minimum internal temperatures based on the level of heat needed to destroy harmful bacteria. These are the numbers that actually determine whether meat is safe:
- Beef, pork, veal, and lamb (steaks, chops, roasts): 145°F, followed by a 3-minute rest
- Ground beef, pork, veal, and lamb: 160°F, no rest needed
- All poultry (whole birds, breasts, thighs, wings, ground): 165°F
- Fish and shellfish: 145°F
- Ham (fresh or smoked, uncooked): 145°F, followed by a 3-minute rest
Ground meat has a higher target than whole cuts for a specific reason. When meat is ground, bacteria from the surface get mixed throughout. A steak only needs to be hot on the outside to kill surface bacteria, but a burger needs to reach a safe temperature all the way through.
How to Use a Meat Thermometer Correctly
Insert the thermometer into the thickest part of the meat, avoiding bone, fat, or gristle, all of which conduct heat differently and will give you a false reading. For thin items like sausage patties or burger patties, push the probe in through the side until the tip reaches the center.
For whole poultry, check the temperature in the innermost part of the thigh, the thickest part of the breast, and the wing joint. These areas are the slowest to cook, so if they’ve hit 165°F, the rest of the bird is safe.
Keep in mind that meat continues cooking after you remove it from the heat. A steak or piece of chicken will typically rise another 3 to 4 degrees while resting. A large roast or whole turkey can climb 10 to 15 degrees. So pulling a roast at 135°F and letting it rest can bring it to 145°F or above without overcooking it.
What Happens If You Eat Undercooked Meat
Undercooked meat can carry several types of bacteria, and the symptoms and timing vary depending on which one you encounter. Salmonella, common in poultry and eggs, typically causes nausea, diarrhea, and fever within 6 to 48 hours. E. coli O157:H7, most associated with undercooked ground beef, can take 1 to 8 days to produce symptoms but can cause severe cramping and bloody diarrhea. Campylobacter, the most common bacterial cause of foodborne illness from poultry, shows up 2 to 5 days after exposure.
Most healthy adults recover from these infections within a week, but they can be serious for young children, elderly adults, pregnant women, and anyone with a weakened immune system. The risk is highest with ground meat and poultry, both of which harbor bacteria more readily than whole muscle cuts.
