The National Academy of Nutrition and Dietetics says that if you enjoy meat rare or medium-rare this may still be fine, but the only safe way to tell if meat that's a little less done is safe, is with an inexpensive instant-read meat thermometer. Relying exclusively on the color or texture of meat is insufficient — specifically a brown color doesn't always confirm safety, while a pink color doesn't necessarily mean that a meat is undercooked and unsafe.
