Police in the southern province of Binh Duong on Wednesday found around 40 tons of milk that had expired nearly a year and a half ago.
The Ancomilk-branded boxes, found at premises of the The Gioi Xanh (Blue World) Co. Ltd. that offers equipment and consultancy services for waste treatment, showed that it was produced in April 2008 and expired in October the same year.
Many of thousands of the milk boxes were left outdoors, some were torn and the stale milk was leaking, the Saigon Giai Phong newspaper reported Wednesday.
Nguyen Tri Binh, director of Blue World, said Phuong Nam Company in the province had between October and December last year hired it to transport the milk from a store at Song Than Industrial Zone to a wastewater treatment factory of Nam Tan Uyen Company for being disposed of. Binh didn't explain why the task has not been done.
According to the contract, the milk would be poured into a treatment lake and the boxes buried, Blue World said.
Last October, Binh Duong authorities discovered 105 tons of Ancomilk at the Song Than Industrial Zone contaminated with melamine. The milk had also expired in October 2008.
Police are carrying out further investigations to find out the origin of the milk in latest case and if it was milk from the previous case. Binh Duong's Department of Natural Resources and Environment said earlier that the milk from the previous case had been destroyed.
