FRESH PORK: Safe Cooking Chart. Cook all raw pork steaks, chops, and roasts to a minimum internal temperature of 145 Â°F as measured with a food thermometer before removing meat from the heat source. For safety and quality, allow meat to rest for at least three minutes before carving or consuming.
Report Abuse. A pork roast (other than a smoked ham) should be cooked to an internal temp of 160 degrees. Then take it out of the oven or off the grill, and let it rest for about 15 minutes. It will continue to cook for the first few minutes and the temp to serve should be 165 to 170.he roast should be removed from the oven when the internal temperature reaches 150Â° to 155Â° and then allowed to stand for 10 to 15 minutes before carving. The temperature of the roast will rise during this time and should reach a desired temperature of 160Â° to 165Â°.
