Sushi is delicious, but because it often contains raw fish and rice, it’s also one of the most perishable foods you can eat. If you’ve ever brought home sushi or had leftovers from a restaurant, you might wonder: how long can sushi sit out? Knowing the answer is important for both food safety and taste.
Quick Answer
Sushi should not sit out at room temperature for more than 2 hours. If the room is above 90°F (32°C), the safe time drops to just 1 hour. After that, bacteria can grow quickly, making it unsafe to eat.
Why Sushi Spoils Quickly
- Raw Fish: Highly perishable and can harbor harmful bacteria if not kept cold.
- Cooked Rice: Sushi rice is seasoned with vinegar, but it’s still moist and prone to bacterial growth.
- Warm Temperatures: Bacteria multiply rapidly between 40°F and 140°F (the “danger zone”).
Safe Sushi Storage Times
| Storage Condition | How Long It Lasts |
|---|---|
| Room Temperature | 1–2 hours |
| Refrigerator (below 40°F) | 24 hours (best quality within same day) |
| Freezer | Not recommended (alters texture of rice & fish) |
How to Tell If Sushi Has Gone Bad
- Smell: Sour, fishy, or ammonia-like odor.
- Texture: Slimy fish or hard, dry rice.
- Appearance: Discoloration or dull, grayish fish.
- Taste: If it tastes “off,” don’t eat it.
Tips for Keeping Sushi Fresh
- Eat sushi as soon as possible after purchase or preparation.
- If storing, refrigerate immediately in an airtight container.
- Place a damp paper towel over sushi before refrigerating to help keep rice moist.
- Never leave sushi sitting out overnight.
Difference Between Raw and Cooked Sushi
- Raw fish sushi (sashimi, nigiri, raw rolls): Most perishable, best eaten immediately.
- Cooked sushi (shrimp, tempura rolls, veggie rolls): Slightly safer, but still should not sit out longer than 2 hours.

FAQ
Can I eat sushi that sat out for 4 hours?
No. Sushi left out that long is in the danger zone and could cause foodborne illness.
Is it safe to eat day-old sushi from the fridge?
Yes, if it has been stored properly in the refrigerator and still smells fresh. However, the quality will decline.
Can I freeze leftover sushi?
Not recommended. Freezing changes the texture of both rice and fish, making it unpleasant.
Why does sushi rice go bad so quickly?
Because it’s seasoned and slightly warm when prepared, it provides an ideal environment for bacteria if not cooled quickly.
Conclusion
Sushi should never sit out at room temperature for more than 2 hours. For best safety and flavor, eat it fresh, or refrigerate leftovers immediately and eat within 24 hours. Sushi with raw fish is the most perishable, while cooked or vegetarian rolls last slightly longer but still require prompt refrigeration.
To keep leftovers fresh, use a good airtight container and always refrigerate as soon as possible.
