Nobody makes any such claims for an emu.
The plus is that it doesn't have the calories or the cholesterol or the fat that beef does. In addition, emu meat is high in iron and vitamin C and is said to take on seasonings and other flavors unusually well. Others compare emu meat to ranch-raised venison, another red meat that is very low in fat. Most often cut into strips or medallions, emu can be substituted for beef, pork, chicken, or turkey in many recipes, and ground emu burgers have found a ready market at adventurous drive-ins in such scattered locales as Auburn and Hopland. But despite these attributes, emu remains an exotic novelty to most consumers, if they have heard of it at all.
