Classical Swine fever reported in Japan 26 years after last outbreak
CSF is a notifiable disease and affects the international trade of pork, however, clinically it is usually considered less severe than ASF. Currently, it is considered endemic in many countries, including China, therefore it is a disease with potential direct and indirect effects to the US industry. Depending on the strain, extensions of outbreak, route of introduction and effectiveness of biosecurity measures to contain and prevent re-introductions, it could offer different levels of risk. Commercial vaccines are available for CSF control.
The last CSF outbreak in Japan was in 1992 in Kumamoto Prefecture, and in 2007 the use of vaccination was banned, and disease eradication was declared in the country. The Japanese swine industry is still recovering from the 2013-2016 PED epidemic. On July 9th-2018, APHIS published the official notice of the OIE exports pork, and it is in the top-10 pork producing countries in the world. FAS/Tokyo estimates Japanese swine slaughter held stable at 16.336 million head in 2017.
At this point, no other cases of CSF are suspected in Japan.
