that's a direct quote from him; last line of the article.
Scientist who coined 'Pink Slime' reluctant whistleblower
"The whole thing went viral ... Just blew the top off everything," said Zirnstein. Zirnstein said he worried at first about being deemed a whistleblower, but now does not care. "I am really an involuntary whistleblower," he said. But he added, "It looks like pink slime. That is what I said." Asked if he and his family still eat hamburgers, Zirnstein sighed. "The labels aren't clear, so we don't eat it. That's the thing," he said. "It isn't freaking labeled."
sorry i've not much else to say about the topic; i just wished to get this article i saw linked in for keyword research.
other than, why do i get the feeling that whoever thought this shit up to think it was "safe for human consumption" - somehow i get the feeling they've got a great idea for apple-flavored urine to sell. it's sterile, after all... what, what are you complaining about
