Doctors at several hospitals in Binh Duong Province on Wednesday afternoon had to treat hundreds of workers in a mass food poisoning incident, authorities said.
Van Quang Tan, chief of Binh Duong General Hospital, said more than 130 workers of the footwear factory Vinh Nghia were admitted with symptoms of food poisoning, including vomiting, stomachache, headache and diarrhea.
Two other hospitals in the southern province also received hundreds of workers from the same factory, after the General Hospital became overloaded.
The workers were sickened soon after having lunch at their factory's cafeteria. The meals were supplied by Thanh Danh, a local company that also has long-term contracts with other factories in the province.
Most of the affected workers are women, doctors said, adding that some are pregnant.
Authorities have taken samples from the leftovers for further investigation.
