Hi again, Cherrybim.
I don’t imagine the halochos of miut hamotzui follow he FAO’s definition of “often” (I’m not sure why you’re so caught up on herring).
My point about not being the same worms is not to reject any other explanation as illogical, but rather to explain why Rav Elyashiv, Rav Vosner, Rav Karelitz, etc. are not swayed by the argument that the worms must be mutor, since everything is still the same. I would like to hear Rav Belsky’s pshat in “mino gavli”. Please explain, I’m open to listen.
Thanks.
By the way, the psak to assur the fishworms could even be misofeik. Since they are nikor, they are not botel, and we are dealing with an issur d’oraiso.
