Speaking to local media on Thursday morning, the vice chairman of Lang Chanh District People's Committee, Le Duc Tien, said they found no pigs left at the farm during a check on July 31.

"Some staff members were fixing the pollution issues at the farm, and there was no bad smell as of July 31," Tien said, adding that the local Department of Natural Resources and Environment would arrive soon to direct and monitor the work.

The move came after local authorities requested that the pig farm be suspended by July 30. Investigations showed that it was causing serious environmental pollution to surrounding residential areas.

In a decision sent to the company on July 2, Le Duc Giang, Vice Chairman of Thanh Hoa Provincial People's Committee, asked the company to conduct thorough checks on its operations and address all the processes causing pollution.

The farm, which the Agri-Vina Agriculture Investment Company has operated since early this year, was raising some 30,000 pigs.

Earlier, thousands of local households complained about severe environmental pollution caused by the large-scale pig farm since it began operations early this year.

Agri-Vina Agriculture Investment Company was given a licence in late 2023 to operate the farm, which has a capacity of 60,000 pigs and covers 52,000 square metres.

Although the company is currently only raising 30,000 pigs in its first stage, thousands of residents in Tan Phuc, Tam Van, and Lang Chanh Town communes have already complained about the foul odour that has badly affected their lives.

Investigations by local authorities showed that the farm had not adequately treated its waste, causing a foul odour in surrounding areas.
