China reported today its first outbreak of African swine fever, the World Organisation for Animal Health (OIE) said, and had destroyed 336 pigs as it tried to prevent the spread of the disease.
The notification on the OIE website said the outbreak in Shenyang, the capital of the northeastern Liaoning province, began on Wednesday and was ongoing.
African swine fever (ASF) is not harmful to humans but causes haemorrhagic fever in domesticated swine and wild boar that almost always ends in death within a few days.
There is no antidote or vaccine, and the only known method to prevent the disease from spreading is a mass cull of the infected livestock.
The report said 47 pigs had died from the disease and another 336 exposed animals had been put down and disposed of.
The report, made by the China Animal Disease Control Centre under the Agriculture Ministry, listed the origin of the infection as being unknown or inconclusive.
