Thirty-one students at a vocational college in Fujian province have been infected with norovirus after eating at the school’s cafeteria, The Beijing News reported Monday.

The 31 students at Fujian Industrial School in the city of Fuzhou began showing symptoms of vomiting, abdominal cramps, and fever on Friday evening. The school cafeteria’s foodstuffs have since been sealed, pending an inspection. According to the World Health Organization, norovirus can be transmitted through contaminated food or water, or through contact with an infected person or a contaminated surface.

The norovirus outbreak follows last week’s high-profile campus food safety scandal in Chengdu, Sichuan province. The Chinese public has appealed for greater attention to school cafeteria quality control after several food products at the Chengdu primary and secondary school were found covered in mold.
