Most of the victims had eaten the snacks last night and this morning. Within a couple of hours, they felt giddy and nauseous. Almost all the victims are from middle-class families living in Nathu Colony, New Seemapuri and Yamuna Vihar. GTB doctors refused to speculate on whether the atta was adulterated. They said all the victims were out of danger. Delhi Health Minister A.K. Walia, who visited the hospital, said an inquiry has been ordered.
