<br><br>
I [R. Noson Slifkin] recently received Rav Yisroel Belsky's formal
responsum on the anisakis worms that are found in fish (you can download
it

here</a>). It is an excellent, powerful responsum in which he makes two
main points:<br><br>
<ul>
<li>There is no significant difference between the phenomenon of anisakis
worms today and any other worms that have existed.
<li>No halachic authorities, from Chazal through Shulchan Aruch, have
ever given qualifiers on their permission to eat worms found in the flesh
of fish.
</ul>Rav Belsky draws the clear (and to my mind, undisputable) conclusion
that you either say that all worms have always been prohibited, or you
say that all worms have always been, and still are, permitted.<br><br>
Now, Rav Belsky's own conclusion is that Chazal were correct, and the
heter is based on the fact that the worm completes its growth in the
flesh of the fish, not that it spontaneously generated there. As I
discussed in an
<a href="http://www.rationalistjudaism.com/2010/04/worm-controversy.html">
earlier post</a>, I think it's clear that Chazal did mistakenly believe
in spontaneous generation. But, following Rav Herzog etc., I would say
that Chazal's ruling is still valid and thus all worms found in the flesh
of fish are kosher. In other words, I agree with Rav Belsky's conclusion,
while disputing a component of the reasoning. I can also understand
(although I dispute) those who take the approach of R. Lampronti and say
that, since Chazal's science was in error, the heter was invalid from the
outset. <br><br>
