so I was reviewing tolaim today and I’m wondering the following. How do we know that the worms which we witness migrating from the stomach to the flesh did not originate in the flesh and migrate to the stomach and then back? If that is the case, they are muttar.
(I generally assume that unless we can show that there is a metzius which the shulchan aruch does not address, that the metzius of the shulchan aruch is correct.)
