The shelf life of sushi is quite short. So, whether you have restaurant, store-bought, or homemade sushi, you must properly store it to make it last as long as possible.
The good news is that you can safely enjoy day-old sushi (and older) with the proper precautions!
The following explains different types of sushi and how long sushi leftovers are good for. I also cover how to keep your leftover sushi fresh and how to know if it has gone bad.
Sushi Food Safety Concerns
Since sushi uses ingredients that need to be handled carefully, there are some concerns about its safety. But if you use food safety precautions, you can enjoy this delicious food and its leftovers!
Risk of Bacterial Growth
Sushi left at room temperature for too long can be a breeding ground for bacteria, leading to food poisoning. I will outline ways to keep your leftover sushi safe from harmful bacteria.
Raw Fish Concerns
Raw fish in sushi is particularly susceptible to bacterial growth and should be consumed as soon as possible after being made. If not eating it immediately, you want to wrap it and get it in the fridge as quickly as possible.
Vegetable and Egg Concerns
Vegetables and eggs in sushi can also become unsafe if left at room temperature for too long. They are less susceptible to bacterial growth than raw fish, but you want to get them in the fridge within two hours.
Is It Safe to Eat Leftover Sushi?
Yes, it is safe to eat leftover sushi if you refrigerate it quickly. The USDA’s rule of thumb is to not leave any perishable leftovers out for more than 2 hours. However, if it contains raw fish, the sooner, the better. If you refrigerate the sushi within that timeline, it should be safe to eat later.
How much later?…
How Long Is Leftover Sushi Good For?
It’s recommended to eat sushi within 24 hours for best quality, but it can last a little longer if stored properly. How long depends on whether it’s raw or cooked. Raw sushi can be good for 2 days, and cooked sushi for 3-4 days. However, you’ll need to watch for signs of spoilage from day one.
(Remember, these timelines are only if the sushi is refrigerated within 2 hours. You should throw it away if it’s left out at room temperature or above 40 F for more than 2 hours.)
How to Safely Store Leftover Sushi
Whether you buy sushi at the grocery store or from one of the best sushi restaurants in town, you need to store it properly to enjoy it later. The best way is to wrap it properly and refrigerate it as soon as possible.
Leftover sushi should be appropriately wrapped to prevent contamination and preserve its freshness. When wrapping leftover sushi, use an airtight container or plastic wrap to prevent air and bacteria from entering and affecting the quality of the sushi.
Do not store it in the styrofoam box it may have come in as that does not have an airtight seal.
Label the container with the date and time the sushi was made to track how long it has been stored. Proper wrapping and storage will help ensure the sushi remains fresh and safe for longer.
Leftover sushi should be stored in the refrigerator as soon as possible, ideally within two hours of being made. It should be kept below 40°F to prevent bacterial growth that could lead to food poisoning.
Should I Heat Up Leftover Sushi?
Sushi is usually best served at room temperature or slightly chilled, and reheating can result in dry leftover sushi rice and dulled flavors. However, you can reheat leftover sushi if you so desire. Here’s how to easily reheat it without drying it out…
- Put leftover sushi on a microwave-safe plate
- Place it in the microwave WITH a glass of water
- Reheat it in short bursts of 15-30 seconds at a time until you reach the desired temperature.
The glass of water creates steam in the microwave, which keeps the sushi moist. This trick works for reheating pizza, bread, and more.
How to Tell If Leftover Sushi is Good or Bad
If you follow all food safety precautions, your sushi should last a few days in the fridge. But the best thing you can do is double-check your food for spoilage to avoid eating bad sushi.
The following are ways to check your sushi for safety:
- Check the date: Look for the date the sushi was made and ensure it has been stored in the refrigerator for no more than 2-3 days. Store-bought sushi should have an expiration date on the packaging. Otherwise, use the date you ate at the restaurant as your starting date.
- Check the temperature: Ensure the leftover sushi temperature has been maintained below 40°F in the refrigerator. If the sushi sat above 40°F for more than 2 hours, it is best to discard the sushi.
- Check the appearance: Check for any visual signs of spoilage, such as discoloration. If the different components don’t look like their natural color, it is best to give it a hard pass.
- Check the odor: Give your extra sushi the sniff test. While raw sushi may have a slightly fishy smell because it contains raw seafood, it should not have an unpleasant odor. If it has an overly fishy odor, that may indicate bacteria growth.
- Check the texture: If the surface of the sushi appears to have changed, such as the rice being dry or the fish being mushy or slimy, it’s best to discard it.
By following these steps, you can determine whether leftover sushi is safe to eat and minimize the risk of foodborne illness. However, it’s always better to err on the side of caution and discard the sushi if you have any doubts about its safety.
Is Sushi Always Rolled?
Sushi is a traditional Japanese delicacy consisting of bite-sized portions of vinegar rice combined with various ingredients, such as raw fish, vegetables, and egg. The components are generally rolled up in seaweed (nori sheet) and served with soy sauce and wasabi. But it’s not always rolled…
Sushi can also refer to dishes that don’t involve rolling, such as chirashi, a bowl of sushi rice topped with various ingredients. There are many variations of sushi, with new and creative combinations constantly being created.
It is important to note that while raw fish is a common ingredient in sushi, not all sushi contains raw meat. Many cooked, vegan, and vegetarian sushi options are available.
