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.
