Always thought of Thai food, tasty as it is, as a kind of fusion food, combining Indian and Chinese elements. Yeah, you're crazy if you eat Thai dishes that include raw meat or fish, the risk of parasites is just too great, almost certain, I would've thought, if you do it regularly. I do wonder about Japanese sushi, though; I mean I'm as partial to sushi as the next man, and whilst in Japan they're pretty rigourous about their food hygiene, with only minimal cases of parasitic infection occuring, I'm not so sure about the stuff produced and sold here.
