hello99,
1) On the 18 minute audio which was (and probably is still) available on the OU website, Rabbi Belsky clearly says it’s considered part of the fish. This sevara was also referred to in the ou’s press released, which HIE quoted earlier in the coffee room.
2) It is not safe to assume it was below the microscopic level. It is beyond my expertise (above my pay grade) to delve into this, but I have hesrd that many poskim have rejected the microscopic heter based on the facts. We can hardly call a heter based on uncertain facts “compelling”.
3) I still don’t understand how the sevara attributed to R’ Dessler would have any bearing on anisakis. Lice appear to spontaneously generate. These worms do not, since they are found in abundance in the viscera and appear to migrate from there to the flesh.
4) I am sorry if I misunderstood the intent of your quote. Please explain; do you think the predation approach is the same as the heter of the S.A. or not?
I am in the US – east coast.
