The city government of Hamamatsu, Shizuoka Prefecture, central Japan, said Friday that it has identified bread served in school as the cause of mass food poisoning that has sickened more than 1,000 children in the city.
The city ordered Hofuku, a company in Higashi Ward of Hamamatsu that made the bread, to suspend operations for the time being.
As a result of the municipal authorities’ inspection Thursday night of Hofuku’s plant where the bread was made, norovirus was detected from a doorknob of a restroom for female employees, according to officials of the municipal government and the city’s board of education.
Norovirus was found in nine students and eight teachers who ate bread that was made at the factory on Monday and served in school lunch on Tuesday, the officials said.
A seven-year-old boy of an elementary school in Higashi Ward was hospitalized after complaining of stomachache Wednesday night, becoming the first person hospitalized in the food poisoning incident.

A suspected norovirus outbreak has killed four people and infected almost 100 others at a hospital in the Japanese city of Yokohama south of Tokyo, officials said.
Four patients aged between 80 and 97 died of breathing problems and pneumonia between Wednesday and Friday after suffering vomiting and diarrhoea, officials at the city’s Denentoshi Hospital said late Saturday.
A total of 72 patients including the four and 27 hospital staffers have been infected since Tuesday, they said.
The norovirus, which strikes in winter and causes vomiting and diarrhoea, killed six elderly patients at a hospital in Miyazaki in the south and two others at a hospital in the western city of Osaka earlier this month.
It is highly contagious and typically transmitted from person to person.
The virus has been detected in stool samples from 11 of the infected people in Yokohama, the hospital’s director Seiji Shibuya told a news conference.
“Many patients are still suffering from the symptoms and we can’t see an end to the situation,” Shibuya said. “We apologise for our inability to prevent it.”
