How do sushi chefs kill bacteria?

Question

I know that they do flash freezing to kill parasites. But flash freezing only kills parasites, not bacteria. How they kill salmonella and stuff?

Also, when it comes to sushi, you are far more likely to get sick from the rice than the fish. Like others here have said, the fish usually either needs to have parasites or be externally contaminated with bacteria/heat abused to make you sick. 

However, the rice can grow bacteria it Isn’t adequately acidified with sushi vinegar.  it can grow some nasty bacteria very quickly if not acidified and cooled correctly .
