– The main components of your sushi will determine its overall shelf life and storage instructions. In general, the U.S. Food and Drug Administration (FDA) advises that leftovers should not be kept at room temperature for more than 2 hours, and for no more than 1 hour if you’re eating outdoors when the temperature is above 90 degrees Fahrenheit (32 degrees Celsius) ( 2 ).
- This recommendation applies to both raw and cooked sushi, such as sashimi, tempura, and California rolls.
- Raw fish and shellfish can be refrigerated for 1–2 days, but 3–4 days when cooked, according to the U.S.
- Department of Agriculture (USDA) guidelines for storing sushi ( 3 ).
- The objective is to keep sushi out of the “danger zone” of 40–140 o F (4–60 o C) to prevent rapid bacterial growth, which raises the risk of foodborne illness ( 3 ).
Summary Raw sushi can be stored at room temperature for up to two hours and in the refrigerator for one to two days, whereas cooked sushi can be stored in the refrigerator for three to four days.
Is eating sushi at room temperature preferable?
How should sushi be served? Traditionally, sushi is served at room temperature. This means that cold sushi is still edible, but the flavors are enhanced when the temperature is between 20 and 22 degrees Celsius (68–72 F). However, sushi should always be consumed immediately after preparation.
- If it contains raw fish and is older than 24 hours, you should avoid eating it, even if it has been refrigerated.
- Sushi rice is stored and consumed at room temperature, but must be transported or displayed at a much colder temperature.
- This is due to the spread of bacteria and fungi that could contaminate the rice.
In order to prevent this, sushi rice is always mixed with rice vinegar. This acidifies it and inhibits the proliferation of pathogens. In fact, the purpose of (ancient) sushi was to preserve the fish meat by using fermented rice. The meat would be preserved for weeks or months while the rice would be discarded prior to consumption.
How long does sushi remain edible?
Limitations For Room Temperature – The preceding is only valid if sushi is stored at a safe room temperature. If food becomes slightly rancid, there is a small chance of bacterial infection, but our bodies can still handle it. However, if the food is kept outside at temperatures between 39 and 140 degrees, the bacteria may multiply more rapidly, causing the food to spoil quickly.
- Therefore, the length of time sushi can be left out at a party also depends on the local climate.
- Sushi can last a few hours longer in a cold climate than it can in a normal environment.
- Sushi can last a few hours longer in a cold climate than it can in a normal temperature environment.
- However, if you live in a region with a hot and humid climate, food can spoil quickly unless you have a powerful air conditioner.
Sushi can be kept fresh for 4 to 8 hours if the room temperature is maintained at 20 degrees Celsius with the air conditioner operating. Even if the sushi does not have a foul odor, it must be discarded if it is left outside for longer than that period.
