[Avodah] Worm-Infested Sardines II

As a follow-up to this post 
(<http://torahmusings.com/2011/06/worm-infested-sardines/>link), 
I obtained this Q&A of Daf HaKashrus  with permission to publish:

Question:

The note preceding the sardine article/ R’ 
Belsky’s teshuva/ stated that the new scientific 
DNA research proves that as “R’ Belsky Shlita 
concludes that these are the same anisakis worms 
which Halachah permits as being Darni D’Cavri. 
These worms have migrated from the flesh of the 
fish to its gut. R’ Belsky’s conclusion was 
scientifically borne out
”. How did the 
scientific research prove that they migrated from 
the flesh to the gut and not vice-versa?

The Daf responds:

Dear Rabbi ********,

We apologize for the confusion caused by the 
introductory note. You are correct that the DNA 
research only proves that the worms in the gut of 
the sardines are Darni D’Cavri (permitted flesh 
worms). It does not directly indicate the 
direction of the migration. However, Rav Belsky 
explained in a separate teshuva that anisakis 
enter the sardines when they eat infected fish 
(krill). These worms are permitted because they 
initially become visible inside of these very 
small fish and as such the worms were never 
rochesh in the water. Accordingly, the direction 
of the migration is irrelevant.

We should also point out that the fact that the 
worms first become visible inside of the fish is 
only a suggested explanation for the heter. The 
reason for the absolute certainty of the heter is 
that the Gemara says that Darni D’Cavri are mutar 
and the Shulchan Aruch says that worms in the 
flesh are mutar. If anisakis is assur then there 
are no worms in any fish that are mutar and this 
is against the Gemara and Shulchan Aruch.

(Sivan 5771, June 2011) at

It deals in detail with the issue of worms in fish.
