Authorities in central China detained two bosses of a catering company and are investigating four government officials after dozens of students were hospitalised after eating a school lunch last week.
The incident increased scrutiny on the caterer, the Henan branch of Beijing Zhihong Catering Company, and officials discovered it did not have a required food business licence.
Two officials from the local education authority and two from the market supervision authority are under investigation.
