Eight years of extensive research, including work at Kansas State University, has led to a disquieting scenario for swine producers: Feed and feed ingredients could potentially serve as means for the introduction and transmission of foreign animal diseases of swine. Research funding was provided by the National Pork Board. African swine fever, or ASF, is the most significant foreign animal disease threat to U. The primary goal of negative countries, such as the U.
New China swine fever strains point to unlicensed vaccines

BEIJING Reuters - A new form of African swine fever identified in Chinese pig farms is most likely caused by illicit vaccines, industry insiders say, a fresh blow to the world's largest pork producer, still recovering from a devastating epidemic of the virus. Two new strains of African swine fever have infected more than 1, sows on several farms owned by New Hope Liuhe, China's fourth-largest producer, as well as pigs being fattened for the firm by contract farmers, said Yan Zhichun, the company's chief science officer. Though the strains, which are missing one or two key genes present in the wild African swine fever virus, don't kill pigs like the disease that ravaged China's farms in and , they cause a chronic condition that reduces the number of healthy piglets born, Yan told Reuters. At New Hope, and many large producers, infected pigs are culled to prevent the spread, making the disease effectively fatal.
African swine fever - A review of current knowledge
The International Livestock Research Institute ILRI which is based in Nairobi, Kenya, has a comparative advantage to address African swine fever because it has research facilities located in the endemic areas of the disease which allows research activities with the causative virus at source. ILRI offices are located in some of the most affected African countries such as Kenya, Uganda, Tanzania, Burkina faso, Mali and Zimbabwe and also in regional offices where there is a current outbreak such as Vietnam. In early , ILRI commenced research on ASF with a focus on epidemiology and surveillance, diagnostics and assessing the socio-economic impacts of the disease.
African swine fever ASF is a notifiable, virulent swine disease, and is a major threat to animal health and trade for many European Union EU countries. Early detection of the introduction of ASF virus is of paramount importance to be able to limit the potential extent of outbreaks. However, the timely and accurate reporting of ASF primary cases strongly depends on how familiar pig farmers are with the clinical signs, and their motivation to report the disease.
