MOUNTAIN VIEW, Calif.
— A new study from the University of California, Los Angeles (UCLA) suggests that the Japanese and other Pacific Rim countries are getting better at keeping sushi rolls clean.
The study, which was published in the journal Science Advances, used data from over 2,500 sushi restaurants in the United States to analyze how sushi restaurants performed.
It found that sushi restaurants across the Pacific Rim, including Hawaii, California, New Zealand, Japan and Taiwan, have the highest levels of food safety standards among all regions studied.
The researchers looked at restaurant performance for two years, during which they collected data on the quality of food, the number of incidents of foodborne illness, the amount of food waste, the quantity of food in the food processing facility and the amount and type of food stored.
“We found that food quality, hygiene and waste are much better in Japanese restaurants compared to other regions,” said lead author Rakesh Ghosh, associate professor of public health at UCLA’s School of Public Health.
“This finding has been widely accepted in the public health community, but we haven’t yet documented this for sushi restaurants.”
The study found that Japanese restaurants performed about 10 percent better than other regions on food safety measures and waste reduction.
It also found that the sushi industry is one of the most environmentally conscious among food processing industries.
In addition to Japanese restaurants, other studies have found that some sushi-related industries also perform better on food quality and waste prevention than those in other regions.
These studies, Ghosh said, also showed that sushi was a food that people in many other regions ate as a way to enjoy the food.
“Sushi is not just for people who love sushi,” Ghosh explained.
“People are getting really sick from eating sushi.
They are getting sick from people who eat sushi.”
The researchers are hoping to conduct a larger study to see if the Japanese are more likely to eat sushi.
“In a survey of people, sushi consumption was the second most popular food item in Japan, after rice,” Ghoshes co-author and postdoctoral fellow Michael Fussell told Live Science.
“But sushi consumption has been linked to a host of health issues.
So, we think that we can also test whether sushi is good for people and health.”
In the United Kingdom, where sushi is considered a delicacy, the country has recently made it mandatory for people to eat only sushi rolls when dining out, and for people over the age of 18 to only eat sushi rolls if accompanied by an adult.
But this is not the case in Japan.
Ghosh and Fussel hope that their research will help other countries develop policies and regulations to help keep sushi safe.
They hope the findings will help countries such as the United Arab Emirates and India develop better food safety policies, and lead to better sushi dining experiences for consumers.
