but I support this law.. although perhaps not to be strictly applied.
The thing is, when I go into a restaurant, I expect all relevant safety procedures to have been followed to ensure my food is safe to eat. If it's between getting a worm parasite or eating frozen fish, I'd gladly have my fish frozen.
Perhaps a compromise could be reached:
1) Sushi restaurants offer both the frozen and non-frozen varieties. There must be no price difference, and all varieties offered non-frozen must have a frozen equivalent. The menu/waiters must inform patrons of the potential dangers of eating the fresh fish (sort of like cigarette warnings..)
2) Or, allow restaurants to only serve "fresh" fish.. but require they must provide directions to a sushi restaurant within a reasonable distance that serves frozen fish.. as well as the warnings as above.
The point is, consumers should know the heath risks associated with the food they eat. They should have an easily accessible alternative (ie. so they don't feel forced to simply accept what they deem an unreasonable risk just because there are no other options)
