Sushi-Any health risks?

Are there any significant health risk associated with eating sushi? I had some the other day and rather enjoy it, but when I mentioned it to my dad, he acted like I was nuts to eat raw fish and kept going on about how it’s not healthy to eat raw meat.

So what is the straight dope on this? I imagine that sushi resteraunts have to pass the same inspections as every other resturant in the nation(US) and if a significant portion of people were posioned by it, it would be all over the news. I know that raw chicken/pork isn’t considered good for you, so does fish have unique properties, or is there some other preperation going on that I’m not aware of?
