Can Sushi Go Bad

As with all perishable food, sushi can go bad when they pass their shelf life. To know “how long can sushi stay out of the fridge?”You need to learn what’s inside sushi. As the traditional Japanese cuisine often includes raw and light fish meat, it is also one of the popular toppings on a sushi roll, from raw salmon, tuna to scallops and bluefin belly.

It is commonly known that sushi contains raw fish, which can be dangerous to consume as fish meat is easily spoiled. That’s why many people tend to shy away from sushi, but sushi has more than just raw meat.

Unlike sashimi, a piece of raw fish meat dipped with soy sauce; most sushi types will have vinegar rice as the base. The block of seasoned white rice is packed evenly with mixed seaweeds inside. The toppings options of sushi are various as you can find avocados, egg omelet, tempura, cheese, cucumbers, carrots with different kinds of sauces on the menu to choose from.

How To Tell If Sushi Has Gone Bad

To know how long does sushi stay good, you need to know how to tell if sushi has gone bad to avoid food poisoning. Normally, you can check the freshness of the food by observing its color, texture, and smell.

Here are some common tips for you to spot when going to a sushi restaurant:

When checking bad sushi, you should check their exterior first to spot any signs of spoilage. In particular, a good sushi roll should have a compact structure. The block of rice should be firm and white to hold the toppings on top. If you find the rice falling apart or has any gray discoloration, it indicates spoiled cooked rice, which you should discard right away.

Regarding the toppings, there are many signs you need to look at for each type of topping.

For fishes, the meat should have a fresh look with a firm yet soft texture. If the color of the fish is dull and pale, it possibly loses its freshness. You can also poke the meat to check. If the texture falls apart or is too dry, there is a high chance of spoiled fish meat.

Another sign to look for when you’re having fish sushi is slimy fish. If a slimy film or milky discharge is coming off the fish, that’s a clear sign of spoiled and rotting fish. At this point, you should throw away the whole batch for your safety.

Suppose the toppings are fruits and vegetables; they should have a certain level of moisture and freshness. If there is any discoloration on the leaves, noticeable black or brown spots on them, the sushi might not give you an overall good taste, but they can still be edible.

In case you’re uncertain after looking at the sushi exterior, check the state by smelling it. Normally, spoiled food or rotten ingredients give off a sour smell. But you should not mistake the sour smell of rotting food with the intense and sharp aroma of vinegar or lime, which are normal in sushi rolls.
