Sushi = under cooked.
Tilapia is not in sushi. But i will never eat tilapia again..even before this story.
Bingo.
Uncooked food has been known to be a health hazard for......thousands of years?? Especially protein.
All you sushi lovers — you deserve what you get.
As to where the food comes from, so what? Are our food inspections/certifications worthless? Looks like a YUP. Eat local or farmed in the US.
Commercially available sushi fish in the U.S. is frozen to kill any parasites. Beware, however, if you are traveling to another country, particularly Asia.
