There are ways to handle and prepare most meats so that they're reasonably safe. And even the "safe temperature" people generally see are the instantaneous temperature (if they hit that, the most common sources of food borne illness they carry are dead), but you can achieve the same results if you can keep the internal temperature at a lower temperature for longer.
