How long does it take for sushi to spoil unrefrigerated?

Sushi, especially raw fish sushi, is extremely perishable and can spoil very quickly at room temperature.

Here's a general timeline:

* Within 2 hours: Bacteria start to multiply rapidly, especially in warmer temperatures.

* After 4 hours: The risk of food poisoning increases significantly.

* After 6 hours: Sushi is no longer safe to eat.

Factors that affect spoilage:

* Temperature: Warmer temperatures speed up spoilage.

* Type of fish: Some fish are more prone to spoilage than others.

* Ingredients: Rice and other ingredients also contribute to the overall spoilage.

Important note:

Even if sushi looks and smells fine, it doesn't mean it's safe to eat. Bacteria can grow without visible signs. Always prioritize safety and discard any unrefrigerated sushi after 2 hours.
