How long can takeaway sushi be stored? Leaving it in the wrong place risks spoilage sooner than expected.

Japanese cuisine like sushi is a favorite for many, but since it contains fresh, raw ingredients with delicate textures, taking it home requires special care regarding temperature and cleanliness.

How long can takeaway sushi be left outside the fridge?

According to food safety principles, temperatures between 4 and 6 degrees Celsius are considered the "Danger Zone," where bacteria can multiply rapidly.

• Typical room temperature (international): Should not be left out of the fridge for more than 2hours.
• In Thailand’s climate (hotter than 32°C): The safe time decreases to no more than 1 hour. Beyond this, the risk of bacteria like Vibrio parahaemolyticus or Salmonella multiplying is very high. How many days can sushi be stored in the fridge? (Raw vs Cooked)
