    • Raw Fish Sushi: Sushi made with raw fish, such as salmon or tuna, should ideally be consumed within 24 hours of refrigeration for optimal freshness and flavor.
    • Cooked Fish Sushi: Sushi containing cooked fish, like eel or shrimp, can last slightly longer, typically up to 48 hours, when stored correctly in the refrigerator.
    • Vegetable Sushi: Vegetarian sushi, such as avocado or cucumber rolls, can maintain its freshness for about 48 hours if refrigerated properly.
    • Sashimi: Fresh sashimi, thinly sliced raw fish or seafood served without rice, is highly perishable. It should be consumed within 24 hours of refrigeration.
  2. Room Temperature Sushi: It is crucial to exercise caution when leaving sushi at room temperature, as bacteria can multiply rapidly in this environment. Sushi should not be left unrefrigerated for more than two hours. The warmer the room temperature, the shorter the safe duration.
    • If sushi has been left at room temperature for less than two hours, it can still be consumed, but it’s important to rely on your senses to assess its freshness before eating.
    • If sushi has been left at room temperature for more than two hours, it is best to discard it to avoid the risk of foodborne illnesses.

Remember, these timeframes are general guidelines, and it’s essential to use your judgment and assess the sushi’s appearance, smell, and taste before consuming it. Using the best-by date printed on the package of sushi is also a good way to tell how long your specific type of sushi lasts.

How to Tell if Sushi Is Bad?

Determining if sushi has gone bad requires attentiveness to the following signs:

  1. Visual Inspection: Observe the sushi closely. If you notice any discoloration, such as a faded or dull appearance, or if the rice looks dry or crumbly, it may be an indication of spoilage.
  2. Foul Odor: Fresh sushi should have a pleasant, seaweed-like aroma. If you detect a strong, unpleasant, or fishy smell, it is a sign that the sushi has gone bad.
  3. Texture Check: When you touch the sushi, the fish should feel firm and have a smooth texture. If the fish feels slimy, mushy, or overly soft, it’s a clear indication that the sushi is past its prime.
  4. Taste Test: The ultimate test is, of course, the taste. If the flavors are off, or if you experience any unusual or unpleasant tastes, it’s best to err on the side of caution and discard the sushi.

Remember, consuming spoiled sushi can lead to foodborne illnesses, so it’s crucial to prioritize your health and safety.
