Pablo,
Have had more bouts of botulism as well as other stomach problems in US of A than India, so there goes the hygiene theory, I also remember a ABC channel expose that most salad was being cut by homeless guys in expensive NYC joints.
Point is Sushi and other Japanese stuff is really expensive affair so the clientele who comes wield influence, mostly 5 stars and exclusive restaurants serve Japanese and if anyone gets sick,there will be price to pay in every sense. India being a peninsula gets abundant fresh fish,,most exported to EU and US, so that in itself is not a problem.Actually the idea of raw fish was abhorred and its only now that the younger generation here in India has accepted Japanese to an extent, some for being stylish rather than taste, some for taste as well.Usually people here were apprehensive about food from anywhere else than India as the presumption was that the others eat almost everything living.
