You'd turn the beef into totally unrecognizable meat paste that could come from any number of species. Pulverize the meat, wash it with solvents, and cook until there is nothing left of the original protein structures or flavor (i.e charcoal). Just unique enough in physical composition to say this lump of burnt paste is different from that lump of burnt paste but not enough information to say anything else about it or what it originally may have been.
