Fifteen students of a primary school in southern Vietnam were hospitalized Thursday for stomach ache, headache, and nausea after eating lunches provided by a local company.

The third and fourth graders of Vo Thi Sau Primary School, located in My Phuoc Ward of Ben Cat Town in Binh Duong Province, were admitted to Ben Cat Health Center with food poisoning symptoms.

Five of them were in severe conditions and sent to the emergency ward.

They are all day-boarders at the school, displaying the symptoms just 30 minutes after having lunch.

Phu Nhat Hao, a Vietnamese firm, supplied the school with 388 lunch meals, said Huynh Thi Lang, principal of the primary school.

Lang added that the company, headquartered in Binh Duong’s Tan Uyen Town, has provided the school with meals since August last year.

Last month, the parents of students at Long Binh Primary School in the province’s Bau Bang District protested against the firm for providing stale food.    

According to the Food Safety Department of Binh Duong, Phu Nhat Hao now supplies meals to 18 schools in the southern province.

Chau Thi Bich, vice director of the Ben Cat Health Center, said she had sent staff to get food samples at Vo Thi Sau for testing to pool evidence for dealing with the case.
