How Long Does Sashimi Stay Fresh?
Safety and freshness guide for raw fish leftovers
Sashimi should be consumed within 1 day of purchase or preparation when kept in the refrigerator.
Sashimi is a delicacy consisting of thinly sliced raw fish or meat, prized for its delicate texture and clean flavor. Because these proteins are not cooked to kill pathogens, they are highly susceptible to rapid bacterial growth and enzymatic degradation. Maintaining a strict cold chain is essential for preventing foodborne illness. When storing leftover sashimi, it must be kept in an airtight container within the coldest part of your refrigerator. However, due to the high risk associated with raw seafood spoilage, the window for safe consumption is much narrower than most other leftovers. Prioritizing freshness is the only way to ensure both safety and quality.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
How long can I keep sashimi in the refrigerator?
Sashimi should be consumed within 1 day of purchase or preparation. Because it is a safety-critical raw seafood product, freshness is paramount for preventing illness.
What is the best way to store leftover sashimi?
To maintain quality, wrap the fish tightly in plastic wrap or place it in an airtight container. Store it in the coldest part of your refrigerator to slow spoilage.
Can I freeze sashimi for later use?
Freezing is not recommended for high-quality sashimi. The process significantly degrades the delicate texture and flavor, making it unsuitable for raw consumption.
Is it safe to cook sashimi that has passed its expiration date?
No. While cooking kills many bacteria, it does not eliminate certain heat-stable toxins produced by bacteria in spoiled fish. If it is past the 1-day window, discard it.
When dealing with raw fish, prioritize safety: if you have any doubt about its freshness, throw it out.
