There are some things that taste better with time—a fine wine, an aged cheese, some leftovers. Sushi, however, is not one of them. We love repurposing leftovers, and our slew of recipes for leftover pulled pork and lamb and mashed potatoes will prove it. But sushi is one of those things that will always be best fresh. While it's hard not to finish an Alaska roll or spicy tuna roll, you might have found yourself wondering whether it's safe to eat leftover sushi, and for how many days.
According to Katie Heil, Seller/Server Learning Experience Design Manager at Certus, sushi with raw fish should be consumed within one to two days of preparation. Sushi without raw fish might be safe for almost a week.
Heil cites the Food Code from the USFDA which requires food prepared and refrigerated in a food establishment to be consumed, sold, or discarded within no more than seven days. (The day it was prepared counts as day one.)
"For example, if you made vegetarian sushi rolls on a Thursday, the rolls would need to be eaten or thrown out no later than the following Wednesday," she added.
But what about the rice in sushi? You may have heard that leftover rice can cause food poisoning.
"The rice is a factor in why sushi storage time is limited," said Heil. Cooked rice is what's called Time/Temperature for Safety (TCS) food, according to Heil. This means that it needs to be refrigerated at or below 41 degrees Fahrenheit to remain safe to eat.
But Heil says that sushi rice is a little more complicated because of the addition of vinegar. The use of vinegar can be a "method of preservation," or make it so it's no longer considered a TCS food. In this case, the restaurant would need to apply for a variance and create a safety plan which would determine length of storage.
"To be safe, it’s probably a best practice to eat sushi within a day or two of preparation, and be sure to refrigerate it in the meantime!" she said.
