Vietnam has reported African swine fever (ASF) for the first time, and new cases in domestic pigs have been recorded in the past week in China, Italy, Mongolia, Poland, Romania and Zimbabwe.
First cases of ASF have been reported in Vietnam. Pigs at three farms in two provinces in the north of the country — Thai Binh and Hung Yen — have tested positive for the virus, reports Vietnam Plus, and the virus has subsequently been detected in neighboring backyard pig herds of the Thai Binh outbreak, but not at nearby farms. In Hung Yen, samples from other farms in the area are still being analyzed.
Culling of infected pigs and thorough disinfection of the premises have been ordered by the Ministry of Agriculture and Rural Development. Surveillance of all pig farms in affected communes is ongoing, and the transport and slaughter of pigs are being tightly controlled by the authorities.
Based on information from the World Organisation for Animal Health (OIE), this is the first time ASF has ever been reported in Vietnam.
