At least 55 girl students of Government Polytechnic College here were hospitalised following complaints of nausea and diarrhoea after they had food from the hostel, police said.
Some 25 students, staying in the college hostel, had consumed rice yesterday and they complained of nausea and diarrhoea and were immediately taken to government hospital late last night.
Another 30 students were taken to hospital with similar symptoms this morning and all the students were undergoing treatment, they said.
The hospital dean Edwin Joe said the students were admitted after they complained of nausea and diarrhoea and their condition was out of danger.
The samples of the food and drinking water the students had consumed were sent for testing, the official said.
District Collector T N Hariharan visited the students at the hospital and inquired about their health condition with the authorities.
