Pork reheats safely in both microwave and conventional ovens. It is important to reheat pork to an internal temperature of at least 160 degrees Fahrenheit to destroy microorganisms and make it safe for consumption.
The best way to reheat large quantities of pork is in a conventional oven set at 325 degrees Fahrenheit. The pork should be covered tightly to keep it from drying out, and then heated until the interior temperature reaches the appropriate level. An instant read thermometer makes it easy to take the temperature of the meat. Smaller quantities of meat can be covered and reheated in a microwave oven set at medium power.
