How do you know if your sushi has gone bad?

There are several signs that sushi is spoiled! Pay attention to the smell, color, and texture of the sushi. A sour or unpleasant smell is a clear sign of spoilage! Sticky or slimy fish and hard rice are also indicators that it is time to discard the sushi! Wow! Sushi is one of the most delicious and healthy foods out there, but it’s important to make sure it’s fresh.

Keep an eye out for these six signs to determine if your sushi has gone bad: odor, appearance, texture, taste, temperature, and time.

  1. Smell: Fresh sushi should have a mild, fresh sea air odor that will make your mouth water. If you notice a strong, unpleasant, or sour smell, it’s a clear indication that the sushi is no longer fresh and it’s time to say goodbye.
  2. Appearance: When selecting fish for sushi, it is crucial to pay attention to its color and texture! Fresh fish should be bright and shiny, without any discoloration or slimy spots. If the fish appears dull or dry, or if there is any discoloration, it may indicate spoilage.
  3. Texture: Moreover, the texture of the fish should be firm and spring back when pressed lightly. If the fish feels mushy, it may not be fresh!
  4. Rice: The sushi rice should be sticky and moist, but not too hard or soft. If the rice is dry or overly sticky, it may be old.
  5. Expiration date and packaging: When purchasing pre-packaged sushi, always check the expiration date and packaging condition. Damaged or bloated packaging may indicate spoilage!
  6. Overall Quality: It is SO important to pay attention to the presentation of sushi! This can indicate the level of care taken in its preparation and potential freshness issues.

And if you’re unsure about the freshness of your sushi, don’t take any chances – it’s always better to be safe than sorry and discard it immediately! If you’re doubting whether sushi is still good to eat, it’s likely that it’s no longer fresh! It’s always better to err on the side of caution and avoid consuming it. Remember, it’s better to be safe than sorry!
