An obscure group of ultra-Orthodox rabbis has banned smoked salmon because of the presence of a parasitic worm.
Chevra Mehadrin, based in Monsey, N.Y., announced the ban late last month because of the presence of anisakis in salmon, the New York Post reported.
Rabbi Moshe Elefant of the mainstream Orthodox Union dismissed the claim, saying salmon is not a problem.
"The issue has been resolved in Jewish law for hundreds of years already," he said.
