The siblings, residents of Lawsohtun area in the city, started complaining of severe headache and vomiting soon after they consumed ready to eat noodles prepared by their mother yesterday afternoon, the officer at Laban police station said.
"Three of them were admitted to Ganesh Das Hospital and the other two were rushed to Shillong Civil Hospital for immediate medical attention," Deputy Commissioner of Food Safety S N Sangma said.
The Food Safety office immediately ordered an inquiry into the incident and the reports were awaited, Sangma said.
"Prima facie, they ate some noodles. We are to ascertain what kind of noodles, their date of manufacturing and whether they are safe," he said.
The incident was the first such case after Maggi was banned in the state last month for high content of MSG and lead.
At least 36 samples of various kinds of instant noodles imported from Singapore, Nepal and Thailand have been sent for tests at the Guwahati-based Public Health Laboratory for testing, state government officials said.
