Does sushi have to be refrigerated?

Sushi with raw fish (nigiri, sashimi, maki with raw fish):

* Yes, it must be refrigerated. Raw fish is highly perishable and can spoil quickly at room temperature.

* Keep it in the refrigerator at 40°F (4°C) or below.

* It's best to eat it within 24 hours of preparation.

Sushi with cooked fish or other ingredients (vegetarian sushi, tempura sushi):

* It's generally safe to leave at room temperature for a few hours. However, the longer it's out, the higher the risk of bacteria growth.

* Refrigerate it if you're not eating it right away.

* Cooked sushi typically stays fresh for 3-4 days in the refrigerator.

Important Considerations:

* Always follow the specific instructions provided by the restaurant or sushi maker.

* If you see any signs of spoilage, such as a slimy texture, a sour smell, or a discoloration, throw the sushi away.

* Sushi rice can become hard and dry after being refrigerated. It's best to eat it as soon as possible after being made.

In general, it's always best to err on the side of caution and refrigerate your sushi, especially if it contains raw fish. This will help ensure its freshness and safety.
