can anyone tell me more info about some rumor i heard? is it true that fish heads even if farm raised can a worm problem?
yes. farmed Norweigan salmon is free of Anisakis worms in the flesh but has a skin parasite that invades the oral cavity. They hide in the gills, under the toungue ete. Carp and mullet have worms in their head, even when farmed.
See here more more resources regaring checking all of the Simanim http://shaareihoraah.org/wordpress/?p=655
can you please clarify in English? I checked the link and all the sources are in Hebrew. I already cooked my salmon heads. I washed them well but did not know to check for anything.
If the parasites are only in the heads, do I cut off the head before cooking it, and then eat what I cooked, or can I cook the fish whole, and dispose of the head before putting it on a plate?
Rav Vaye writes that you must split the head in half and remove the gills and all internal organs. Then rinse thoroughly and inspect. I don’t know if it helps to do this after cooking.
They are visible, not so small at all if you know how to look. If you cooked it with the head it will not make the entire fish Assur. You can cut it off afterwards.
Hello: Don’t we say that these worms are Kosher anyway because they grew inside the fish?
I just spoke to the head of Rav Revach’s fish department and he said salmon heads can be cleaned even after cooking. Also, they do not need to be split completely in two, just a slit on the bottom, remove the gills and rinse well
Sam2,
Kukiyani are assur.
I called the store and they said they check the heads. Also, I washed them very well and did a quick visual check. I just don’t know what to look for. There is nowhere to slit the bottom so I guess they do that at the fish store. thanx everyone for your help.
Sam: They are not worms and do not originate inside the fish. They are lice also called Argulus and migrate from th eskin to the mouth. They can range up to over an inch long.
Sam 2 – Nematode worms grow inside the flesh and are kosher. The salmon and carp lice are parasites that grow in the water and attach themselves to the fish for food. They are “Sheretz Hamayim” and would need fins and scales to be kosher! Since they haven’t got them they are osur like all non kosher sea creatures. The salmon louse is easy to detect, it is about 5-10mm long. Half of it is round and the rest is a tail. The carp louse is much smaller about 4mm long, oval, and translucent. It is best to watch an expert checking before attemting oneself.
So, besides the fish brain which is delicious, what part of the head do you actually eat?
