It is a three way machloqes -- (a) you can't even them at all, (b) only zeh
achar zeh and (c) they may even be eaten bevas achas.

But I think the issue is in how we define rov and whether the
probabilities add if we rely on them in one maaseh, if we rely in them
altogether, or not add at all. Can mi'ut be undone through recombination,
and if so, how?

To my mind, the parallel case in taaroves would be subjecting the
mixture to a cenrafuge. Now, eg, the top of the mix has too much issur
for bitul. Does one thereby undo the bitul?



We were talking about consuming the approved-but-not-certified product. I
believe it's really a case of both probability AND taaroves. After all,
we aren't relying on bitul for a substance we know to be there, we are
relying on bitul in order to not have to know -- the issur is itself only
"present" as a mi'ut (or perhaps even ruba) deleisa leqaman.

Tir'u baTov!
