Fortyeight school students in this Haryana district fell ill after having contaminated mid-day meal Thursday, health officials said.
The incident happened in two government-run primary schools in two villages - Doda Khedi and Gobindgarh, a health official said.
"After eating the food, students started complaining of vomiting and dizziness," he said.
"At least 48 students were immediately rushed to the nearest hospital. Ten students were administered glucose while others were discharged," he added.
"We have sealed the food sample and sent it to the laboratory for testing. If we find any kind of contamination, then strict action will be taken against the guilty," the official said.
Mid-day meal is supplied in over 100 government schools here by a local NGO.
Sources in the district administration said an official found a dead lizard in the food and thereafter schools were told not to serve the food.
"However, this information could not reach the schools of Doda Khedi and Gobindgarh. Students ate contaminated food and fell ill," said a district administration official, on condition of anonymity.
Under the Mid-day Meal Scheme, free lunch is provided in government schools.
