Blue ear disease has been discovered in Ho Chi Minh City, prompting local agencies to destroy 194 pigs in District 12, the city's Animal Health Agency announced Friday.
The southern city has yet to be listed as an official outbreak site because the virus has only been found in healthy pigs, Tuoi Tre newspaper quoted Hoang Van Nam, chief of the Department of Animal Health under the Ministry of Agriculture and Rural Development as saying.
As of Friday the disease, known as Porcine Reproductive and Respiratory Syndrome, has hit 16 provinces across the country, according to the department.
Since late last month over 43,000 pigs have been sickened, half of which have been destroyed, Duong Van Ky, an official from the department said.
In June 2009, the department annouced that Vietnam had successfully curbed the spread of foot-and-mouth disease, bird flu and blue ear disease.
On April 3, however, blue ear cropped up again in the northern province of Hai Duong.
