hello99 – Watch what your implying; your comments are reminiscent of when PETA filmed the shchita process at the Rubashkin plant. After the film was shown, the amharatzim were crying that shchita is tzar bal chai, cruelty to animals, and that shchita should be banned.
All the great poskim and g’dolim of thousands of years had no problem with the shchita process or with these fish worms (which are delicious in gefilta fish and herring).
So be careful.
