The children complained of uneasiness after consuming the meal at Senduari Middle School, and were admitted to Sadar hospital at Hajipur, district headquarters of Vaishali, a district official said.

"All the children are now safe," he said. "All of them, except two, were discharged after preliminary treatment at the hospital," he added.

Samples of the meal have been collected by police for forensic examination. According to officials, some children said a lizard was found in the mid-day meal served to them.
