Eighty-three college students had food poisoning after eating sardine sandwiches from the canteen on Thursday.
Ten of the Maktab Rendah Sains Mara Kuala Berang students were admitted to the Kuala Terengganu hospital and 50 at the hospital here. The others received outpatient treatment.
Form Four student Siti Fatimah Sulaiman, 16, said those affected had eaten the sardine sandwiches served by the canteen.
The students were rushed to the Hulu Terengganu Hospital by their teachers after they complained of severe diarrhoea at 3am on Friday.
College principal Mohamed Sanuar Yusoff said the students were in stable condition.
