The workers, including women, of Renuka Inc were found vomiting and fell unconscious due to nausea this afternoon.
They were rushed to the nearby Sarvoday Hospital in Sector-19 here, said R S Bhati, an official in the company's HR department.
The workers informed the hospital staff that they fell ill after drinking water from the RO system installed in the factory.
The workers used to drink this water on routine basis but have never complained of any problem, Bhati said.
He said that the workers were brought with same symptoms and have been given the required medication.
Later, all the workers were discharged except four, who are still being treated.
None of the cases brought were serious, he said.
Bhati said that the company used to provide RO water for the workers to take care of their health.
However, the reasons how the workers fell ill after drinking water from the same RO are still to be investigated.
