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?

Answer 1

Natural wasabi actually has antimicrobial properties, it would kill any bacteria in traditional Japanese sushi. The fake green stuff, not so much. Otherwise, just normal food safety handling and keeping the fish chilled is enough.
