Sushi is a popular Japanese delicacy that is enjoyed by many all over the world. It is made with raw fish, vegetables, and rice wrapped in seaweed or served as a roll. However, sushi leftovers are not as enjoyable as the fresh meal. The question often arises as to how long is leftover sushi safe to eat? In this article, we will explore the factors that influence sushi’s shelf life and how to properly store and reheat leftover sushi.

Factors Affecting the Shelf Life of Sushi

Freshness of Ingredients

The freshness of the ingredients used in sushi plays a crucial role in its shelf life. The rice used in sushi should be cooked fresh and should be free from any contaminants. The fish and vegetables used in sushi should also be fresh and of high quality. If the ingredients used in sushi are not fresh, there is a higher chance of bacterial growth, which can result in spoilage and Food poisoning.

Storage Temperature

The storage temperature of sushi is another important factor that affects its shelf life. Sushi should be stored at a temperature between 0 – 5°C (32 – 41°F). If sushi is stored at room temperature, the growth of bacteria increases, which can lead to the spoilage of the Food.


The time sushi is left out of refrigeration also affects its shelf life. Sushi should not be left at room temperature for more than 2 hours. If the sushi has been left out for more than 2 hours, it is best to discard it.

The shelf life of leftover sushi depends on various factors such as storage temperature, freshness of ingredients, and duration of storage. Generally, leftover sushi can only be stored for a maximum of 24 hours. After this period, there is an increased risk of bacterial growth, which can lead to Food poisoning.

How To Store Leftover Sushi

To properly store leftover sushi, it should be placed in an airtight container and refrigerated immediately. If the sushi will not be consumed within 24 hours, it is best to freeze it. Frozen sushi can last up to 2 months if stored correctly. It is important to note that frozen sushi may not retain its original flavor and texture, and it is always best to consume sushi fresh whenever possible.

How To Reheat Sushi

Reheating sushi is not recommended as it can result in the loss of flavor and texture. However, if you must reheat sushi, it should be done in a microwave or oven. The sushi should be heated until it reaches an internal temperature of 75°C (165°F) to ensure that any harmful bacteria are destroyed. It is important to note that reheating sushi may not be safe and, in some cases, can increase the likelihood of Food poisoning.


In conclusion, leftover sushi should be consumed within 24 hours of its preparation to avoid the risk of Food poisoning. The freshness of ingredients, storage temperature, and duration of storage all have an impact on sushi’s shelf life. Proper storage and reheating techniques are essential to minimize the risk of bacterial growth. Whenever possible, it is always best to consume sushi fresh and avoid reheating it.
