China’s agriculture ministry on Sunday said a new case of African swine fever had been confirmed in the country’s northwestern province of Gansu. The outbreak occurred on a farm with 109 pigs in the city of Qingyang, with the viral disease infecting 44 of the pigs and killing nine, the Ministry of Agriculture and Rural Affairs said, citing a China Animal Disease Control Center report…Full Article: Xinhua Jan 2019

  • In late December 2018, scientists at Jilin University’s College of Animal Sciences developed transgenic CSF-resistant pigs by utilizing the CRISPR (clustered regularly interspaced short palindromic repeats)/Cas9 gene-editing tool with the RNA interference (RNAi) technique. Classical swine fever (CSF or hog cholera) and African swine fever (ASF) are highly virulent pig diseases that share near identical symptoms and death rates. As a result, laboratory tests are needed to distinguish between the two. In general, ASF is genetically “more complex” and is caused by an unrelated DNA virus in comparison to CSF.
  • On 25 December 2018, China’s General Administration of Customs (GAC) announced that it had detected ASFV in protein feed (derived from pig’s blood) from a subsidiary of Tianjin Baodi Agricultural Science and Technology. The contaminated protein feed, nearly 74 MTs worth, originated from 12 slaughterhouses in Tianjin Municipality. A ban on using pig’s blood in animal feed had been in effect since mid-September 2018.
  • On 21 November 2018, China instituted new rules and more stringent regulations regarding the movement of pigs. The new rules require farmers to report cases of African swine fever and incentivizes individuals to report outbreaks.
  • On 11 November 2018, Tangrenshen Group (SHE:002567) announced that African swine fever had been detected in animal feed samples procured by its subsidiary (51% owned) Shenzhen Bili Meiyingwei Nutrition Feed (aka Shenzhen Premix INVE Nutrition). In 2017, animal feed sales for Tangrenshen Group (SHE:002567) totaled CNY 12.6 billion (USD 1.81 billion). In 2016, Tangrenshen Group acquired Shenzhen Premix INVE Nutrition from INVE Belgium.
  • On 13 September 2018, the Ministry of Agriculture and Rural Affairs of the People’s Republic of China banned food waste and pig’s blood as raw materials for animal (pig) feed in provinces/regions and neighboring areas where African swine fever had been detected.
  • In mid-June 2018, roughly 400 pigs at a farm near Shenyang, Liaoning Province, China, began showing symptoms of African swine fever.
  • African swine fever virus (ASFV) is a highly contagious disease of pigs that has a near 100% mortality rate. The disease was first reported in Kenya in 1921 and was introduced to the Caucasus region when it spread to Georgia in mid-2007. Since this introduction, ASFV has spread to Armenia, Azerbaijan, Iran, and Russia. From 2007 to 2017, Russia reported more than 1,000 ASFV outbreaks that resulted in approximately 800,000 pigs being killed. From March to October 2017, there were outbreaks of ASFV in Siberia, causing concern that the disease could spread to China. In August 2018, the FAO noted that ASFV strain detected in China was “similar” to the strain detected in Russia in 2017.
