Fish with white flesh can be checked [after the skin is removed] on a light box, by shining a bright flashlight from underneath, or by holding up to a bright light. The worms may appear extended or coiled in a circle. Wild Salmon or other pink colored fish require an ultraviolet light and expertise to check.

*1 Generally not infested and does not require checking, however there have been instances that worms have been found.
*2 According to many Poskim. Recently there has been research done on a few of the herrings on the market and most (and possibly all) have been found to be less than a Miut Hamotzui- accordingly it would be Muttar according to all opinions.
*3 Norwegian Wild is actually “halachically” farm raised, since it is caged and does not feed on Krill
מיעוט שאינו מצוי Although it is possible for the upper area adjacent to the stomach to be infested, at the present time inspections have shown it to be a 4 which does not require checking.
*5 [*] These fish have been checked and appear to be clean but further research is continuing.
*6 Found near the neck [area of the stomach]. Alaskan halibut may be infested in other areas as well.
*7 Sometimes it is actually made from sea bass (see above).
