Last September Classical Swine Fever (CSF) was detected in Japan for the first time in 26 years (see The eradication of classical swine fever in Japan), in Gifu Prefecture (see Japan: MAFF Confirms Classical Swine Fever Outbreak), and then in Aichi Prefecture the following December.
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. But neither virus infects humans.Since then we've seen 31 outbreaks in farms, all restricted to Gifu and neighboring Aichi Prefecture, along hundreds of infected wild boar detected in these two Prefectures. Additionally, some preventative culling was ordered in Osaka, Shiga, and Nagano Prefectures where pigs were shipped from the infected regions.
Today, however, after a two week lull in reported outbreaks we have the announcement of the first infected farm outside of Gifu and Aichi, this time in neighboring Mie Prefecture.This is the 7th farm outbreak in the past 42 days, and the 32nd overall. Although the last OIE update was a month ago, at that time more than 720 infected wild boar had been detected across Gifu and Aichi prefecture.
Today's (translated) announcement from Japan's MAFF:
About confirmation (the 32 domestic cases) of the pseudo-illness of pig cholera in Mie prefecture
Reiwa original year July 24
Ministry of Agriculture, Forestry and Fisheries
Today, a suspected case of hog cholera has been confirmed at a farm in Inabe, Mie Prefecture, which is within 10 km of the wild boar positive confirmation point and has been monitored.
We will make every effort on preventive measures against this disease.
We would like cooperation to refrain strictly from coverage on the spot as there is a risk of causing the spread of this disease.
1. Outline of outbreak farm
Location: Inabe, Mie Prefecture
The feeding situation: 4,058
2. HistoryWhile this territorial expansion of CSF wasn't entirely unexpected, it further dashes the hopes of a rapid eradication of the disease from Japan, and reinforces how difficult - once released - it can be to put a biological genie back into the bottle.
(1) Mie Prefecture, on Monday, July 22nd, received a report from the farm that the breeding pig died, and carried out an inspection by a livestock quarantine officer.3. Future response
(2) On the same day, there was suspicion of hog cholera by inspection at the livestock health and hygiene center, so we sent materials to the National Research Institute for Animal Health (Note) on Tuesday (Tuesday) and carried out genetic analysis. Because the clinical symptoms and test results were not consistent, we decided to conduct a re-examination based on the opinion of the disease subcommittee on cattle and pigs.
(3) When the test was conducted after collecting the sample again, it turned out that it was a suspected case of pig cholera today (Wednesday, July 24).
(Note) Japan's only specialized research institute on animal health
Based on "specific livestock epidemic disease prevention policy about pig cholera", we will make sure about the following epidemic measures.
(1) We will promptly and properly implement necessary epidemic prevention measures such as killing and burning of pig breeding on the farm, and setting of movement restricted area.4. Other
(2) About farms in movement restricted area, we carry out outbreak situation check examination immediately.
(3) In order to prevent the spread of infection, we will strengthen disinfection around the outbreak farm and establish disinfection points on major roads.
(4) We dispatch a national epidemiological research team to investigate the infection route.
(5) We will make thorough early detection and early notification of this disease.
(6) We will strive to provide accurate information to producers, consumers, distributors, etc. as well as working closely with relevant government agencies.
(7) We will thoroughly provide guidance on compliance with the management standards for sanitation such as disinfection of farms and prevention of invasion of wildlife to farms.
(8) Investigate the route of infection and prevent spread, assume all possibilities for investigation.
(1) Porcine cholera is a disease of swine and wild boar and does not infect humans. In addition, infected pig meat does not go on the market.
(2) We ask for your cooperation in the field of on-site coverage from the fact that it may cause the spread of the disease and that it may violate the privacy of farmers. In particular, coverage using a helicopter is an obstacle to epidemic prevention work, so please strictly refrain.
(3) Since we will continue to provide prompt and accurate information, we ask for your cooperation not to be confused by people such as producers or consumers due to groundless rumors.
