The following are the preliminary findings of various fish experts. We will update this list as new information is received.
The Anisakis worm is found in the following fish (frozen or fresh) and may not be eaten unless checked for worms. [Even with a hechscher]
Butterfish
Canned Salmon (wild)
Cod: Scrod, Hake
Flounder: Yellow Tail/ Wild Dabs/ Black Backs, Turbot, Yellow Fin Sole
Halibut
Pacific Red Snapper (Eastern or Atlantic Red Snapper is a different variety and is OK)
Fillet fish sticks or other breaded fish products
Red Perch
Sable a.k.a Black Cod [In NY, some smokehouses use Chilean Sea Bass but call it Sable (which is also a problem)
Sole
Yellow Fin Sole
The following fish do not require checking:
Carp
Farm Raised Salmon [E.g. Atlantic, Norwegian, Chilean, New Zealand, British Columbia)
Gefilte Fish
Herring fillet
Lox [Farm raised, if wild would state “wild”]
Minced Fish Sticks
Pike
Pollock – Atlantic
Sardines from Morocco, Philippines, Portugal
Tilapia
Trout
Tuna
Whitefish: Michigan – Lake Superior [Some allow the Canadian as well]
Whiting
Checking:Fish with white flesh can be checked [after the skin is removed) by shining a strong flashlight from underneath or holding up to a bright light. They may appear as extended worms or coiled in a circle. They are readily visible. Salmon or pink fish require an ultraviolet light and if infested cannot be removed.
