After having lunch in the cafeteria of a private school in Xinjiang 21 students became unwell and were hospitalized.
The students at Zhongcheng Private School, in Wensu County, complained of sore heads, bellyaches and were vomiting after lunch on Wednesday, according to a local health official.
Nineteen of the students aged from six to 14 were discharged from hospital the same day after treatment, said the official. Two others were still in hospital but not in critical condition.
The school said undercooked beans may have caused the poisoning.
The county's health monitoring authorities have run tests on the students for further examination.
