Around 150 workers were admitted to the EPZ hospital. However, all of them were released before evening, hospital sources said.

Around 200 workers of sewing section of JSM Garment, a US-Bangladesh joint venture factory at sector no. 6 of EPZ, fell sick at around 11:00am due to drinking the water provided by the garment authority and began to feel severe abdominal pain, EPZ sources said.

Around ten of them were provided saline and others received first aid at the EPZ hospital.

EPZ General Manger Ataul Hoque told the Daily Star that the workers were supplied water from the garment's internal line, not from the EPZ line.

However EPZ authority formed a three-member probe committee led by EPZ Industrial Relation Manager Md Mahmud Hasan to investigate the incident.
