Hanoi  - Vietnamese authorities have fined a Philippines food processing company 6,000 dollars after a dyke break at a factory reservoir discharged untreated wastewater into a river, an official said Friday.

San Miguel Pure Foods Vietnam was fined for violating four separate environmental laws, said Pham Danh, director of the Department of Natural Resources and Environment in the province of Binh Duong, where the dyke break occurred on July 25.

The company was also ordered to pay 67,000 dollars in overdue environmental protection fees.

The dyke break discharged over 230,000 cubic meters of untreated wastewater into the Thi Tinh River. The polluted water killed fish and threatened drinking water supplies in Binh Duong province and nearby Ho Chi Minh City.

The company may also have to pay compensation to affected households, earlier news reports said.

San Miguel Pure Foods Vietnam is a subsidiary of Manila-based San Miguel Pure Foods Company. The company was already on Binh Duong province's black list of environment polluters before the accident, as well as a list of the top 25 polluters in Ho Chi Minh City in 2008, Danh said.

Vietnam last year halted the operations of Taiwanese-owned condiment company Vedan Vietnam for discharging untreated waste into a river through concealed pipes. The company was fined 5.5 million dollars. (dpa)
