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.
To check doneness, use a digital cooking thermometer. The National Pork Board follows the guidance of the U.S. Department of Agriculture. 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°
