About 40 girl students in a school in Pune fell ill after they ate dinner in the hostel mess and were admitted to a hospital.
The girls, aged between 10 and 16, are students of 'Sevasadan'. They complained of stomach ache and nausea after having their meal on Saturday night and were taken to the hospital yesterday for treatment, school and hospital officials told news agency PTI.
Out of those treated, 17 girls were discharged and remaining students were stable and out of danger, they added.
