As many as 148 employees of a garment company in southern Vietnam have been hospitalized shortly after a dinner at their work place on Wednesday, local media reported Thursday.

After showing symptoms of food poisoning, including stomachache and vomiting, the victims, who work for the Terratex Vietnam Limited Co. in Ho Chi Minh City, were sent to hospital Thursday morning.

The victims also included 20 pregnant women who suffered from headache and bellyache, the Voice of Vietnam reported.

Doctor Nguyen Xuan Hieu, who received the workers, said that some victims were discharged from hospital, but two others are currently in critical condition.

According to the report, the employees said they had eaten boiled eggs, toasted chicken, pork and sprouts.

Terratex Company reported several cases of food poisoning in 2007 and 2011, causing over 370 workers to be hospitalized. The cause of Wednesday's suspected food poisoning is under investigation.
