Perak Health Department director Datuk Dr Juita Ghazalie said some of the students started showing symptoms of vomiting, nausea, diarrhoea, dizziness, fever and abdominal pain early on Sunday.
“The students sought outpatient treatment at Kampar Hospital and nearby government and private clinics.
“All are in stable condition and under close observation,” she said here yesterday.
Dr Juita said stool samples, oral swabs of the food handlers and samples of the food had been taken and sent for analysis to find out the cause of any possible contamination.
She said the cafeteria was ordered closed with immediate effect, pending the results of the tests.
The cafeteria operator, who had only just taken over the contract to supply food, has been slapped with a RM1,000 fine under Regulation 34 of the Food Act.
On Wednesday, some 53 students at the Malay College Kuala Kangsar went down with food poisoning after having meals at the dining hall.
