I wonder why you can eat sushi raw though. Cooked sushi (and yes there is such a thing) is better than raw sushi, but both of them are right up there with eating insects to me.
I love sushi! When we lived in the big city there is only one place we would go for sushi because we trusted the quality...never opt for low quality sushi ick. You are able to eat it raw because the fish is supposed to be properly frozen to kill off the bad bacterias and such. Never eat sushi from fish that hasn't been properly chilled. There are some types of cooked sushi I like with eel sauce yummy. I find raw tuna and salmon especially tasty. Now I'm craving some mmmm.
