Now the USDA says it's safe to cook pork to 145Â°F, which is in effect, medium as opposed to well-done. Pork cooked medium might look a little bit pink in the middle, but that's perfectly all right. In fact, it's great. My own personal preference for cooking pork is 135Â° to 140Â°F.
The National Pork Board recommends cooking pork chops, roasts, and tenderloin to an internal. temperature between 145Â° F. (medium rare) and 160Â° F. (medium), followed by a 3 minute rest. Since large cuts increase approximately 10Â° F. while resting, remove them from the heat at 150Â°. F. followed by a 10 minute rest.
