A reader, Joseph, submitted the following comment, which I thought worthy of publishing as a post: Regarding the claim by R. Bleich that there are no poskim who subscribe to R. Slifkin's thesis regarding halachos based on mistaken factual premises, this is certainly mistaken. Just to give one example, Rav Hershel Schachter, in a recent Q&A session in London (in front of at least 50 people), discussed this exact case, and made reference to the Dor Revi'i. I asked him about the anisakis question, and he said that Chazal believed in spontaneous generation, in accordance with the common belief in that era, and that this is the basis for why they allowed anisakis worms.
