How long does sushi last before spoiling?

Sushi, a delicacy often prepared with fresh and raw ingredients, has a limited shelf life, making proper storage crucial for enjoyment and safety. Experts advise that sushi should not be left at room temperature for more than two hours.

Sushi fresh should smell mild, like the sea or almost have no smell. If it gives off a strong, sour, ammonia-like or clearly unpleasant odor, do not consume it

The duration for which sushi remains safe to eat depends heavily on its preparation and storage method. Sushi containing raw fish or seafood, such as sashimi, is best consumed within one to two days after refrigeration. Sushi with tempura or cooked ingredients generally lasts longer; tempura sushi can be kept for three to four days in the refrigerator, while sushi with fully cooked protein like shrimp might last up to a week, though cooked salmon or tuna sushi should be consumed within two days. Sushi made with cooked meat or chicken can last up to two months if frozen.

The fish should have a bright and uniform color, typical of its species

The U.S. Department of Agriculture emphasizes keeping fish and seafood dishes out of the "danger zone" – temperatures between 4 and 60 degrees Celsius where bacteria multiply rapidly. The Spanish Agency for Food Safety and Nutrition (AESAN) suggests that visual and olfactory cues are key indicators of spoilage. Fresh sushi should have a mild or no smell. A strong, sour, or unpleasant odor, slimy or sticky fish, dry or sour-smelling rice, or any signs of mold indicate that the sushi is no longer safe for consumption.

If the fish or seafood is slimy, sticky or excessively soft, it is a sign that it is not fit for consumption

To extend sushi's usability, AESAN recommends using the freshest ingredients possible, especially for rolls containing fish or seafood. Storing sushi at a refrigerator temperature of -18 degrees Celsius until consumption is also advised to minimize risks.

The rice should remain compact and moist, not dry or with a sour smell. If you notice mold or unusual color changes, discard it
