Cooking pork tenderloin to the correct temperature is essential for ensuring its safety and maximizing its flavor and texture. The ideal internal temperature for cooked pork tenderloin is 145 degrees Fahrenheit, as measured by a meat thermometer inserted into the thickest part of the meat. At this temperature, the pork will be cooked through but still remain tender and juicy.
Cooking pork tenderloin to the proper temperature also helps to prevent foodborne illness. Pork that is undercooked may contain harmful bacteria, such as Salmonella and E. coli, which can cause food poisoning. Cooking the pork to the correct temperature kills these bacteria, making it safe to eat.
