Scientist claims to have made an edible steak out of human feces. Huh?


Hearing about unexpected things, people used to say, "How do they think up these things? There must be something in the water…."


The Digital Trends web site, among others (see video), reports that a scientist has devised a way to make meat, of a sort, from feces:

Mitsuyuki Ikeda, a researcher from the Okayama Laboratory, has developed steaks based on proteins from human excrement. Tokyo Sewage approached the scientist because of an overabundance of sewage mud. They asked him to explore the possible uses of the sewage and Ikeda found that the mud contained a great deal of protein because of all the bacteria. The researchers then extracted those proteins, combined them with a reaction enhancer and put it in an exploder which created the artificial steak. The "meat" is 63% proteins, 25% carbohydrates, 3% lipids and 9% minerals. The researchers color the poop meat red with food coloring and enhance the flavor with soy protein. Initial tests have people saying it even tastes like beef.

We somewhat eagerly (and somewhat not) await confirmation of this.

The new development follows, in its way, the pioneering work of Mayu Yamamoto of the International Medical Center of Japan, who developed a way to extract vanillin - vanilla fragrance and flavoring - from cow dung. Yamamoto was awarded the 2007 Ig Nobel Prize in chemistry.

(Thanks to investigators Bruce Gellerman and Ron Josephson for bringing this to our attention.)

I did a little googling to try to figure out if anyone had exposed this as a hoax, nothing definitive but someone from slashdot wrote up a post here where they did a search on google news for archived stories involving either the supposed lead scientist, "Mitsuyuki Ikeda", or "Environmental Assessment Center, Okayama, Japan", and found stories on meat from human poop have cropped up periodically over the years, a bunch from 2009 and a few from back in 1993 (here's a 1993 story from the Philadelphia Inquirer and a 1993 story from "News of the Weird", and doing a similar search for "Mitsuyuki Ikeda" I also found a story from Deseret News). Of course it's possible that this guy does exist and that he's just sort of a lone crank who keeps pushing this story and every once in a while gets news organizations to bite, but I think it's more likely that the whole thing is a hoax and that the TV program above hired actors to do a fake story inspired by the written reports (the youtube video doesn't give any info on what show the clip came from, might have been a tabloid program or a tv equivalent of "news of the weird"...note at 1:34 the label on the fridge is "shit burger", definitely seems like a wink to the audience).
