Ah yes. Good point. However, as Abd points out you can avoid this by
not eating the brain or spinal chord. And remember, this is cultured
meat, which has big advantages in this regard:
* You start with a single donor cell. So don't use a brain cell!
* You can produce any number of samples from the cell and then test
them for prions or genetic problems such as proteins that do not fold
properly (as you mentioned).
Once you are sure the meat is okay, then you produce a lot of it. I
think I read that a single cell could produce a significant fraction
of the world supply of meat, although it runs out eventually. (Stops dividing.)
These advantages are similar to the ones derived from cloning. In
fact, it is more or less the same thing, except that cloning is
natural after the first step, and you only get one animal. The point
is, you know beforehand how much meat the animal will have, and what
the quality will be. It also resembles cloning in that concerns about
the safety of cloned animals have been raised. I think these concerns
are reasonable and should be tested for, both for cloning and cultured meat.
