While much of the rest of Asia continues to either prepare for, or battle against, the arrival of African Swine Fever (ASF) - Japan has, for more than a year - been dealing with the return of Classical Swine Fever (CSF) after an absence of 26 years.
What began with a single farm outbreak in Gifu Prefecture in September of 2017 has now expanded to 46 farm outbreaks (and wild boar detections) across 5 Prefectures, and (thus far, only) infected wild boar detected in two adjacent prefectures (Toyama & newly added Ishikawa).Much like ASF, CSF does not affect human health, but it can be devastating to the pork industry. Classical Swine Fever, however, is caused by a different virus (genus Pestivirus, family Flaviviridae).
We've the latest (translated) outbreak report from Japan's MAFF, followed by excerpts from the latest OIE report, detailing wild boar detections across 7 Prefectures.
Confirmation of suspected affected animals of swine fever in Saitama Prefecture, about (46 case was in Japan)
Ryowa first year October 11,
the Ministry of Agriculture, Forestry and Fisheries
Today, suspected affected animals of swine fever has been confirmed in wild boar positive confirmation point from there within 10km monitored which has been a Saitama Prefecture Honjo of the farm.
We are taken all possible measures for the quarantine measures for the disease.
Interview in the field, thank you for your cooperation as strictly refrain from such that there is a risk that cause the spread of the disease.
1. Overview of the occurrence farm
- Location: Saitama Prefecture Honjo
- breeding situation: 224 head
2. Background
From OIE 24/09/2019: Classical swine fever, Japan, (Follow-up report No. 36):(1) Saitama Prefecture, October 10 (Thursday), from the farm, received a report of a breeding pig has exhibited abnormal, we conducted a site inspection by animal health inspectors.
(2) the same day, because the suspicion of swine fever is caused by the inspection at the Livestock Hygiene Service Center, was subjected to a thorough examination, today (October 11 (Friday)), turned out to be a suspected affected animals of swine fever want did.
(3) For this reason, along with the epidemic prevention measures for feeding pigs of the farm, feeding pig farms (the prefecture Kamikawa-cho) the farm and feeding management who is the same also with the suspected affected animals of swine fever, take quarantine measures masu (suspected affected animals total: 2,084 horses (1 units 2 farm)).

While this territorial expansion of CSF wasn't entirely unexpected, it further complicates the eradication of this disease from Japan, and reinforces how difficult - once released - it can be to put a biological genie back into the bottle.
