African swine fever keeps spreading in Asia, threatening food security

And many of the newly hit countries are even less prepared to deal with ASF than China, they say, which has so far failed to end its outbreaks. Studies of 68 outbreaks in China concluded that 34% were caused by swill feeding, 46% by contaminated vehicles and workers, and 19% by the transport of live pigs and products. To stem outbreaks, China also culls all pigs in a 3-kilometer zone around an infected herd, sets up inspection and disinfection stations to control farm traffic within a 10-kilometer buffer zone, and closes live pig markets in the affected region.
