if there are "bad" parasites in some fish, what are these parasites? surely science has names, other than worms and bugs for them. what is a parasite. name bad parasites. i do know that some warm water fish, particularly the large ones, are thought to have parasites that are not good.

but this is nonsense . fish make up a reasonable percentage of the american foodstuff, and we describe the problems as "worms and parasites". and they are bad!!! what are these thingies in the fishies? we spend a billion bucks to flash freeze and thaw all the fish. why? let's not talk to medical science, let's find a real science that can tell us what horrible posioning fish freezing is stopping.
