JAPANESE scientists have turned raw sewage into a a protein-rich creation that resembles beef in texture and hope to make it also taste and smell like beef. Mitsuyuki Ikeda, a member of the team, said: "We wanted to show that what comes out of the body can be recycled to go back into the body."

Raw sewage is turned into rich mud to which soya bean, food additives and steak sauce are added to give it an appetising smell. Ikeda believes that one day, the refined burger might be used to feed livestock.
