If sushi stays overnight, you'd better not eat it, because it is likely to go bad. Eating it again at this time is very bad for your health. At the same time, you should also pay attention to developing good living habits and eating habits, and be careful not to eat expired or overnight food. If it must stay overnight, it is best to put it in the refrigerator, so that the effect is better.
Extended data:
Usually, sushi is made of fresh ingredients. Except for a few ingredients such as vegetables, sushi made of fresh ingredients, such as seafood and meat, needs to be eaten within two days after it is made. Try not to stay too long, otherwise food deterioration will easily lead to gastrointestinal diseases, which is very bad for health. Vegetarian sushi is generally recommended to be eaten within 6 hours after it is cooked, so it is best not to eat sushi overnight.
At the same time, people who eat sushi should also go to a regular sushi restaurant to eat, because some unclean sushi may also cause illness.
