Can you eat day old sushi. Sushi is a popular Japanese dish that has become increasingly popular around the world.

However, one question that often arises is whether it’s safe to eat day-old sushi. While many people assume that sushi should be consumed fresh, the answer to this question is more nuanced than a simple “yes” or “no.”

In this article, we will explore the factors that can influence the safety and quality of day-old sushi, including the type of sushi, how it was stored, and the conditions in which it was prepared. We will also discuss some general guidelines for consuming sushi safely, whether it’s fresh or leftover.

Yes, you can eat day-old sushi, but whether or not it’s safe depends on how it was stored and the ingredients used.

Raw fish, which is the main ingredient in sushi, is highly perishable, and if it is not stored properly, it can cause food poisoning.

The rice used in sushi can also spoil if left unrefrigerated for too long. Therefore, it’s important to handle sushi with care to avoid foodborne illnesses.

Factors that Affect the Safety of Day-Old Sushi

Several factors affect the safety of day-old sushi, including:

1. Storage Temperature

The storage temperature plays a crucial role in determining the safety of day-old sushi. Sushi should be stored at a temperature below 40°F to prevent bacterial growth.

If sushi is left at room temperature for more than two hours, bacteria can multiply rapidly, leading to food poisoning. Therefore, it’s important to refrigerate sushi as soon as possible after it has been prepared.

2. Type of Fish

The type of fish used in sushi also affects its safety. Some fish, such as salmon and tuna, are less prone to spoilage and can be eaten after a day in the refrigerator.

However, other types of fish, such as mackerel and squid, spoil more quickly and should be consumed within a few hours of preparation. Additionally, some fish contain higher levels of mercury, which can be harmful if consumed in large quantities.

3. Preparation Method

The preparation method also affects the safety of day-old sushi. Sushi that is made with raw fish that has been frozen for a minimum of seven days at -4°F is generally safer to eat than sushi made with fresh raw fish.

Freezing kills any parasites that may be present in the fish, reducing the risk of foodborne illnesses.

4. Type of Sushi

Different types of sushi have varying shelf lives. For example, nigiri sushi, which consists of a piece of fish placed on top of a small ball of rice, can be eaten the next day if stored properly.

However, sushi rolls, which contain more ingredients, are more prone to spoilage and should be consumed within a few hours of preparation.

If you have leftover sushi, here are some tips for storing it safely:

1. Refrigerate Immediately

As mentioned earlier, sushi should be refrigerated as soon as possible after it has been prepared.

If you plan to consume the sushi the next day, store it in an airtight container and place it in the refrigerator immediately.

2. Keep Sushi and Rice Separate

Sushi and rice should be stored separately to prevent the rice from absorbing moisture from the sushi, which can cause it to spoil quickly. Store the sushi on one side of the container and the rice on the other side.

3. Cover with Plastic Wrap

Cover the container with plastic wrap to prevent air from entering and to keep the sushi fresh. Make sure the plastic wrap is tightly sealed around the edges of the container.

4. Use within 24 Hours

Sushi should be consumed within 24 hours of preparation. If you notice any changes in texture or smell, discard the sushi immediately.


How can you tell if sushi has gone bad?

Sushi that has gone bad may have a sour smell, a slimy texture, or a grayish color. If you are unsure whether your sushi has gone bad, it is best to err on the side of caution and throw it away.

Can you reheat day-old sushi?

No, it is not recommended to reheat sushi. Sushi is meant to be eaten cold, and reheating it can cause the texture and flavor to change.

How should day-old sushi be stored?

Day-old sushi should be stored in an airtight container in the refrigerator. If possible, it should be stored in a separate container from any other foods to prevent cross-contamination.

How long can you keep leftover sushi in the refrigerator?

Leftover sushi should be consumed within 24 hours of being prepared. If it has been left out at room temperature for more than two hours, it should be discarded.

What are some tips for safely consuming day-old sushi?

To safely consume day-old sushi, make sure to inspect it for any signs of spoilage before eating. Also, be sure to use clean utensils and plates when serving and eating sushi to prevent the spread of bacteria.


In conclusion, eating day-old sushi can be safe if it has been stored properly and kept refrigerated. However, it is recommended to consume sushi as soon as possible after it is prepared to ensure the best quality and freshness. Eating sushi that has been left out at room temperature for an extended period can increase the risk of foodborne illnesses. Additionally, sushi with raw fish should be consumed within 24 hours of being prepared to reduce the risk of bacterial growth. Ultimately, it is important to use your best judgment and consider the storage conditions and length of time the sushi has been sitting out before deciding whether to eat it or not.
