Japan: MAFF Confirms Classical Swine Fever Outbreak

Gifu Prefecture - Credit Wikipedia


Amid growing concerns over the spread of African Swine Fever (ASF) in China,  Japan - for the first time in 26 years - is reporting an outbreak of Classical Swine Fever (CSF) in Gifu Prefecture.
Often clinically indistinguishable from ASF, Classical Swine Fever is caused by a different virus (genus Pestivirus, family Flaviviridae).
Like ASF, CSF is highly contagious, and can be economically devastating for pork producers, although it tends to produce much lower mortality in pigs. Unlike with ASF, there is a vaccine for Classical Swine Fever.
Neither disease is considered zoonotic threat.
Japan is one of 35 countries (see map below) that has been certified by the OIE as being free of the disease, with their last outbreak reported in the early 1990s.

This (translated) announcement overnight from Japan's MAFF:
The determination of the corresponding policy in the "Ministry of Agriculture, Forestry and Fisheries swine fever epidemic prevention headquarters."

We'll have to wait to see whether this outbreak is quickly contained, and (hopefully) how it was introduced into this farm. As far as the history of CSF eradication in Japan is concerned, in 2007 MAFF produced the following summary:
The eradication of classical swine fever in Japan
Classical swine fever, which is an acute infectious disease in pigs, existed throughout Japan but the outbreaks had decreased sharply with the improvement of the disease control and herd management technologies and the implementation of a live vaccine from 1969. No outbreak has been observed since 1992.

Under such circumstances, eradication program has been introduced step by step since 1996 to establish control measures without vaccination and thus to fully eradicate this disease with the cooperation of prefecture and local governments, producers and all other related organizations.

As a part of the measures, we have completely banned vaccinations since April 1st, 2006, and watched the disease. One year had passed since then and we had reported the achievement of the eradication program to the Office International des Epizooties (OIE). According to the requirement of the OIE cod
e, Japan had become a classical swine fever free country on April 1st, 2007.

A reminder that while we watch and wait for one pathogenic threat, it is very easy to be blindsided by something different coming out of left field.
