Authorities in the south-central Vietnamese province of Khanh Hoa have recorded an outbreak of African swine fever in the pig herd of a local household.

The outbreak was detected in the herd of 24 pigs belonging to Nguyen Van Kiem in Phuoc Dong Commune, Nha Trang City.

The provincial Department of Livestock and Veterinary Medicine confirmed on Sunday that three test samples collected from the herd had come back positive for African swine fever.

Local authorities previously examined Kiem’s swine herd on September 15 and noticed that three pigs were showing signs of the disease with such symptoms as hemorrhage, cyanosis of the skin, congested lymph nodes.

They collected samples for lab tests and disposed of the three animals.

The People’s Committee in Phuoc Dong Commune requested Kiem to monitor the condition of his remaining hogs.

However, the man did not comply with regulations on disease prevention and instead sold all of his pigs without reporting to local authorities.

Kiem claimed he had bought the swine herd from a seller in Suoi Dau Commune in Cam Lam District, Khanh Hoa, where an African swine fever outbreak occurred last year.

He gave the pigs foot and mouth disease vaccine shots on July 31 and the blue ear disease jab on August 22.

According to the Khanh Hoa Department of Livestock and Veterinary Medicine, the African swine fever epidemic previously appeared in the province on April 11, 2019.

The epidemic started going out of control in late September the same year, peaking in October, before becoming less serious.

As of December 15, 2019, African swine fever outbreaks had broken out in Dien Khanh, Cam Lam, and Khanh Vinh Districts, as well as Nha Trang and Cam Ranh Cities in Khanh Hoa Province.

More than 13,600 infected pigs weighing nearly 760 tons were destroyed in the province.
