I gave sushi a chance but didn't like it much. Just posting a 'becareful' as my daughter and husband both got hepatitis A (last fall) from eating sushi. Hep A is not long lasting, like the other hep strains, nevertheless they were both quite ill. I am 100% positive this is what made them ill as we don't eat out often and that would be the only thing they consumed that the 3 other members of the household did not. My daughter only ate the california rolls. I was adamant she did not consume any raw meats at her age. I guess it didn't matter as all the various rolls share the same prep areas.
Sushi, when prepared correctly with the right quality of fish, really doesn't offer any higher chance of food poisoning than any other food. It _can_ happen, but you can also get food poisoning from peanut butter, spinach, eggs or ground beef (just to name a few...)
If you like sushi, I'd say go for it - just make sure you buy it from a well-run restaurant or make sure the fish is cooked, not raw (you will usually find cooked fish in sushi sold in grocery stores, for example). And it's best not to try to make your own sushi with raw fish at home.
Edited to add: All that said, there is _some_ risk of food poisoning anytime raw meat is involved. The vinegar used in the preparation of sushi is meant to combat bacterial growth, as is the freezing process required for commercial-grade sushi fish. Someone probably wouldn't want to be eating sushi on a daily basis (espcially since some species - tuna, especially - tend to have high levels of mercury that can accumulate in the body if the fish is consumed frequently). Sushi's not for everyone - I happen to love it as an occasional "treat" and have never gotten ill.
