Take a moment to let that gag reflex subside. Now consider this: it's already been taste-tested, approved, and could eventually become a practical solution to sewage treatment. Someday "bowel burgers" may even provide an easy source of protein for the hungry.
The steaks were first envisioned by Japanese researcher Mitsuyuki Ikeda after he was approached by Tokyo Sewage to come up with a solution for the city's overabundance of sewage mud. Although "eating it" probably wouldn't have occurred to most people, Ikeda recognized that the mud was chock full with protein-rich bacteria.
