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.
Place the pork on a rack in a pan and put it in the oven at 500 deg F. Immediately set the oven to 170 deg F. Roast for several hours until the internal temp of the pork is 165 deg F. This might take 4 hours. If you need to, you can increase the temp to 350 deg F at the end to finish it.
