If worms in fish posed a serious health hazard, one would have expected that Japan, a country in which raw fish are consumed in huge quantities, would have seen severe health effects. But Japan has the healthiest people and the longest life expectancy in the world.
I will yield to the rabbis regarding kashrut, except to say that just this past Thursday I purchased scrod and salmon from my local kosher certified (Vaad of Riverdale) fish store and served them this past Shabat, and I’m cooking sole for a Purim seudah tomorrow. At such time as my local rabbis ban these fish I will abide by their ruling. (I buy all my fish from the same local kosher fish store.)
