The outbreak of African swine fever (ASF) in China surpassed the one-year mark this month since the virus was confirmed there. ASF continues to spread in China and into neighboring countries despite the best efforts of farmers, veterinarians and government officials to contain it. Estimates suggest China, the world’s largest pork producer with nearly a billion hogs, could lose anywhere from 30 percent to 40 percent of sows to the virus. Economists predict it could take China four to six years to get ASF under control. (FarmWeekNow)
