Minimum Internal Cooking Temperatures for Meat: USDA Safe Minimums by Cut

Why the USDA Sets Minimum Internal Temperatures

The United States Department of Agriculture (USDA) publishes minimum internal cooking temperatures for meat to ensure that harmful bacteria, such as Salmonella, E. coli, and Listeria, are destroyed during cooking. These temperatures are based on scientific research showing the heat level needed to kill pathogens in a matter of seconds, making food safe to eat.

The USDA minimums are not about taste or doneness preferences; they are the legal and public-health threshold for safety. For many cuts, you may choose to cook beyond the minimum for texture or flavor, but you should never serve meat below these temperatures.

It is important to note that the USDA temperature guidelines apply to the internal temperature of the meat, not the oven or pan temperature. This is why using a food thermometer is essential—you cannot reliably judge safety by color, firmness, or time alone.

Whole Cuts vs. Ground Meat: The Critical Difference

The USDA draws a clear distinction between whole cuts of meat and ground meat. Whole muscle cuts, such as steaks, roasts, and chops, have bacteria only on the exterior surface. Cooking the outside to a safe temperature is sufficient, which is why a 145°F (63°C) steak with a warm red center is safe.

Ground meat, however, is different. Grinding distributes any surface bacteria throughout the entire batch, so the meat must be cooked all the way through. This is why ground beef, pork, and lamb have a higher minimum of 160°F (71°C).

This distinction explains why you can cook a whole chicken breast to 165°F (74°C) while a ground turkey patty also needs 165°F (74°C)—the poultry minimum is the same for whole and ground, but for red meats the ground version is higher.

Beef, Pork, Lamb, and Veal: 145°F with a Rest

For whole cuts of beef, pork, lamb, and veal—such as steaks, chops, and roasts—the USDA safe minimum is 145°F (63°C), followed by a three-minute rest time. The rest period is crucial because the temperature continues to rise during this time, and the sustained heat helps kill any remaining bacteria.

This temperature applies to pork as well, a change from older guidance that recommended 160°F (71°C). The lower minimum is safe because modern pork production has reduced trichinella risk, and the rest period ensures safety.

If you prefer your meat more well-done, you can cook beyond 145°F (63°C), but you should never serve it below this threshold. For roasts, the same minimum applies, but you should check the temperature in several spots to ensure even cooking.

Poultry: Always 165°F, Whole or Ground

All poultry—chicken, turkey, duck, and goose—must reach a minimum internal temperature of 165°F (74°C), whether it is a whole bird, breast, thigh, or ground. This higher temperature is necessary because poultry can carry Salmonella and Campylobacter, which are more heat-resistant than many other pathogens.

For whole birds, check the temperature in the innermost part of the thigh and wing, as well as the thickest part of the breast. For ground poultry, the same 165°F (74°C) applies, and there is no rest-time exemption—the temperature must be reached and held.

Cooking poultry to 165°F (74°C) will result in a juicy, safe product if you avoid overcooking. Using a thermometer is especially important for poultry because color is not a reliable indicator—pink meat can be safe if it has reached the temperature, and white meat can still be undercooked.

Ham, Fish, and Leftovers: The Exceptions and Extras

Ham has its own rules. Fresh or uncured ham should be cooked to 145°F (63°C) with a rest, like other pork. Pre-cooked or smoked ham, if it is from a USDA-inspected plant, can be eaten cold, but if you reheat it, the USDA recommends 140°F (60°C) for flavor and safety, though 165°F (74°C) is required for leftovers or if it was not stored properly.

Fish and shellfish have a lower safe minimum of 145°F (63°C) or until the flesh is opaque and separates easily with a fork. This is not a USDA meat guideline but is recommended by the FDA; the USDA does not regulate fish.

Leftovers, including meat dishes, should be reheated to 165°F (74°C) to ensure any bacteria that grew during storage are destroyed. This is a universal rule regardless of the original meat type.
