How long can sushi remain out of the fridge and safe to eat?

Sushi, especially raw fish, should be kept refrigerated and consumed within two hours of preparation.

Here's why:

* Bacteria Growth: Raw fish is highly perishable and can quickly become a breeding ground for bacteria that cause food poisoning.

* Temperature Danger Zone: The "danger zone" for bacteria growth is between 40°F and 140°F (4°C and 60°C). Leaving sushi out at room temperature puts it in this danger zone.

Exceptions:

* Cooked sushi: Cooked sushi, such as tempura rolls or sushi with cooked fish, can last a bit longer, up to four hours, outside the refrigerator. However, it's still best to consume it as soon as possible.

* Sushi with rice vinegar: Rice vinegar in sushi rice can help to slightly slow down bacterial growth, but it's still important to keep it refrigerated.

Always err on the side of caution:

* If you're unsure about the safety of your sushi, it's always better to throw it out.

* Don't hesitate to ask your sushi chef about the freshness of their ingredients and how long the sushi has been out of the refrigerator.

Remember: Your health is important! Enjoy your sushi safely.
