The third outbreak of blue-ear disease in Vietnam was confirmed September 8, according to Thanh Nien Daily. The disease has killed at least 400 pigs in a breeding farm in the Mekong Delta province of Bac Lieu.
Precautions were taken to control the disease when the first 30 pigs died, but to no avail, according to Lam Tri Thong, head of the provincial Animal Health Department.
To prevent further spread, the farm has been shut down and pigs have not been allowed to be sold from the affected area, the official said.
Vietnam suffered from a nationwide outbreak of blue-ear disease five months ago, and the disease re-emerged in the central province of Quang Nam in July.
