Rav Vaye in the 8 page letter published on YW quotes John Smith, M. Joie and B. Berland (presumably a scientific research paper) as saying in my translation back to English “The worm hatches from its egg on the floor of the sea and exits the egg at a microscopic size and it is impossible to see without a microscope. The worm when it hatches from its egg and is swallowed by the shrimp is 200-300 microns (.3mm) long and 14 microns wide, by way of illustration if one would cut a mite into 12 pieces would it be possible to see a single piece?
Rav Falk’s main reason to be matir seems to be to be:
???? ?????”? ????? ?? ?? ???? ???? ?? ???? ?? ???? ?? ?? ???? ????? ?? ???? ???? ????? ??? ????? ???? ???? ??? ????? ???? ?? ?? ??? ????. ????? ?????? ???? ?? ?? “??? ????” ?? “??? ????” ?? “??? ????” ????? ?? ????? ?? ?? ??? ?? ?? ???? ???? ????? ??? ????. ??? ??? ??”? ? “? ??’ ?”? ??”? “?????? ??????? ?? ????? ????? ??”? ??????? ??? ???? ?? ?????? ??? ?? ????? ????? ?????? ????, ???? ?? ?????? ???? ???? ??? ?????? ?????? ??? ??? ?????? ????? ?? ?? ?????? ???? ??? ???? ???? ?????? ????? ???? ???? ?????.
In other words, the Rema permits ????? ???? ????? all worms that grow in meat, fish and cheese, since they don’t grow from the ground they are not considered ???? ?? ????. According to this, the Sefardi Poskim should be more ?????.
He uses this as a ????? with two other considerations:
????? ???????? ????? ??????? ???? ???? ?????? ????? ?????? ?? ????? ????? ??? ??? ??? ????? ????? ????? ?? ???? ????? ??? ???? ?? ???? ?????. ?’ ???? ??? ?”?. [?] ???? ?????? ?? ???? ?? ???? ?? ?????? ?? ???? ?? ?? ?? ???? ?? ???? ????? ?? ???? ?????? ???? ?????? ??? ?????? ???? ?? ??? ????? ???? ?? ????? ????, ?’ ???? ??? ?”?.
It’s surprising that no one quotes this ???? from Rav Falk, as this ????? is clearly not new. It is addressed to Rav Tuvia Weiss as a Rav in Antwerp, and he has already been the Gavad of the Eidah HaChareidis in Yerushalaim for a number of years. Actually at the end of the teshuva it is dated ???”? with a current addition.
He also writes:
????? ??? ??’ ?’ ??? ?”? ????? ??’ ?”? ?”? ?’???? ????? ???”? ???? ???? ?????, ???’ ??”? ???? ????? ?? ?? ???? ???? ??? ??????.
