Sure it's propagated from a clean tested starter batch, etc. The problem is that what you don't know can kill you, and there's so much that is unknown, and so much that can kill you.
Do you know how much of the human genome is of recent (and ancient) viral and bacterial origin? Are you aware of how much modification goes on from such sources, and would you even consider such a thing as a risk? The conventional answers would likely be "no", but you might want to take a look at some of the recent discoveries on horizontal gene transfer and the activation of dormant sequences. The same factors in less similar meat, or the GMO's that the food hippies are so terrified of, might not be as risky or familiar to human tissue as the stuff in 'close' meat. Familiarity breeds danger. So there's that and the damaged proteins and their coding, prions, unknown triggers for cancers and other diseases, mutations, etc. I could go on and on here but for the sake of brevity let's just say that the gods simply do not approve. Someday maybe when genetics is completely understood and can be properly engineered, I might take a bite of that sandwich. But certainly not now. Rent the movie Gattaca from 12 years ago if you haven't seen it, and think about how incredibly complex life's coding is, and how little we really know about its processes and interactions. And I apologize for previously misspelling soylent, if there is a correct way to spell a made-up movie word. R.
