s when cut, thereby extending the limited shelf life of the sushi. Sushi bento boxes are a staple of Japanese supermarkets and convenience stores. As these stores began rising in prominence in the 1960s, the labor-intensive cut leaves were increasingly replaced with green plastic to lower costs. This coincided with the increased prevalence of refrigeration, which extended sushi's shelf life without the need for cut leaves. Today plastic strips are commonly used in sushi bento boxes and, to a lesser degree, in sushi presentations found in sushi bars and restaurants. In store-sold or to-go packages of sushi, the plastic leaf strips are often used to prevent the rolls from coming into early or unwanted contact with the ginger and wasabi included with the dish.

(especially Pacific bluefin tuna, bluefin) can harbor high levels of methylmercury, one of many toxins of marine pollution. Frequent or significantly large consumption of methylmercury can lead to developmental defects when consumed by certain higher-risk groups, including women who are pregnant or may become pregnant, nursing mothers, and young children. A 2021 study in Catalonia, Spain reported that the estimated exposure to methylmercury in sushi consumption by adolescents exceeded the tolerable daily intake. A 2011 article reported approximately 18 million people infected with fish-borne Trematoda, flukes worldwide. Such an infection can be dangerous for expecting mothers due to the health risks that medical interventions or treatment measures may pose on the developing fetus. Parasitic infections can have a wide range of health impacts, including bowel obstruction, anemia, liver disease, and more. These illnesses' impact can pose health concerns for the expecting mother and baby. Sashimi or other types of sushi containing raw fish present a risk of infection by three main types of parasites: * ''Clonorchis sinensis'', a Trematoda, fluke which can cause clonorchiasis * ''Anisakis'', a Nematode, roundworm which can cause Anisakiasis#Anisakiasis, anisakiasis * ''Diphyllobothrium'', a Cestoda, tapeworm which can cause diphyllobothriasis For these reasons, EU regulations forbid using raw fish that had not previously been frozen. It must be frozen at temperatures below in all product parts for no less than 24 hours. Fish for sushi may be Flash freezing, flash frozen on fishing boats and by suppliers to temperatures as low as . Super-freezing destroys parasites, and also prevents oxidation of the blood in tuna flesh that causes discoloration at temperatures above . Calls for stricter analysis and regulation of seafood include improved product description. A 2021 DNA study in Italy found 30%-40% of fish species in sushi incorrectly described. Some forms of sushi, notably those containing the fugu pufferfish and some kinds of shellfish, can cause severe poisoning if not prepared properly. Fugu consumption, in particular, can be fatal. Fugu fish has a lethal dose of tetrodotoxin in its internal organs and, by law in many countries, must be prepared by a licensed fugu chef who has passed the prefectural examination in Japan. Licensing involves a written test, a fish-identification test, and a practical test that involves preparing the fugu and separating out the poisonous organs; only about 35 percent of applicants pass.


Sustainable sushi

Sustainable sushi is made from fished or farmed sources that can be maintained or whose future production does not significantly jeopardize the ecosystems from which it is acquired.


Presentation

Traditionally, sushi is served on minimalist Japanese-style, geometric, mono- or duo-tone wood or lacquer plates, keeping with this cuisine's aesthetic qualities. Many sushi restaurants offer fixed-price sets selected by the chef from the catch of the day. These are often graded as , , , and , with the most expensive and the cheapest. Sushi restaurants will often have private booth dining, where guests are asked to remove their shoes, leaving them outside the room; However, most sushi bars offer diners a casual experience with an open dining room concept. Sushi may be served (sushi train) style: color-coded plates of sushi are placed on a conveyor belt from which diners pick as they please. After finishing, the bill is tallied by counting how many plates of each color have been taken. Newer restaurants use barcodes or Radio-frequency identification, RFID tags embedded in the dishes to manage elapsed time after the item was prepared. There is a practice called which entails serving sushi on the naked body of a woman.

, a box with small compartments that hold the various dishes of the meal. Soy sauce is the usual condiment, and sushi is normally served with a small sauce dish or a compartment in the bento. Traditional etiquette suggests that the sushi is turned over so that only the topping is dipped to flavor it; the rice—which has already been seasoned with rice wine vinegar, sugar, salt, mirin, and kombu—would otherwise absorb too much soy sauce and would fall apart. Traditionally, the sushi chef will add an appropriate amount of wasabi to the sushi while preparing it, and the diner should not add more. However, today, wasabi is more a matter of personal taste, and even restaurants in Japan may serve wasabi on the side for customers to use at their discretion, even when there is wasabi already in the dish.
