Cherrybim: So now we’re supposed to follow whichever posek is followed by the majority, even if it’s only because it’s a name brand hechsher? Rav Elyashiv, Rav Vosner, and Rav Karelitz tower above any American poskim today. Also as I mentioned, Rav Belsky Shlit”a is arguing on the rishonim on the sugya. What a shame that Rav Elyashiv, Rav Vosner, and Rav Karelitz, not to mention the Rashb”a, Ramba”m (Sefer Hamitzvos),and Maggid Mishna, don’t work for a nationally recognized hechsher!
BTW, you misread my original statement about herring – I never said it’s dewormed, just that it’s not a problem. I said even if you saw someone eating wild salmon, you can’t assume they hold it’s mutor, maybe it was dewormed. I have no idea whether or not herring is dewormed.
Gefilte fish is not a problem because the worms are ground up, and they become botel (no longer a berya).
