About 50 garment factory workers fell sick yesterday after eating lunch at their workplace in Ashulia, Savar.
Greenlane Shahria's sick workers were admitted to Ganosastha Samajbhittik Medical College Hospital.
According to sources, the authority provided rice, beef, chicken and lentil for lunch.
As soon as the lunch was finished, the garment workers started vomiting and many of them fainted.
Upon being informed, their supervisors rushed them to the hospital.
Doctors at the hospitals said the workers fell sick because of food poisoning.
However, their conditions started to improve gradually after receiving treatment at the hospital.
Production activities at Greenlane Shahria were suspended for several hours after the incident which created a panic wave in other factories situated in the area.
The district administration has formed a three-member committee to ascertain the actual cause of the incident.
