5. Salmonella
In the process of making your sushi, if unhygienic ally or improperly handled the consumer of the particular sushi could be in danger of contacting a bacterium called Salmonella. Any form of germs infested on the sushi could bring about this infection. Present in tunas. Freezing the tuna doesn’t kill the bacteria although exposing it to high temperatures such as cooking it could help, in as much as the infestation of the bacterium didn’t happen after the cooking. The major symptom happens to be stomach flu.
