Question: how long is it safe to eat leftover sushi?
Answer: If the sushi has raw fish, it is okay to take home some leftovers and store them in a refrigerator up to 24 hours. The taste and texture of the sushi may change (e.g. softer sashimi, limp seaweed paper, harder rice), but there should be no harm in eating it 24 hours after it was made.
