Japan MAFF: Farm Outbreaks Of CSF Expand To 6th Prefecture (Nagano)

#14,304

For a second day in a row (see yesterday's blog) a new Japanese Prefecture is reporting their first farm outbreak of Classical Swine Fever; today it's Nagano, which is the 6th Prefecture struck since the virus re-emerged a year ago after an absence of 26 years.  

This is the 42nd farm outbreak reported, although more than 900 wild boar have been found to be positive across at least 7 Prefectures.  The last OIE update (#34) was a month ago, and so those numbers will be changing.

For the first 10 months of this year-long outbreak, only two prefectures reported farm outbreaks (Gifu & Aichi).  In less than 60 days we've seen farm outbreaks expand to 4 new prefectures; Mie, Fukui, Saitama, and Nagano.

While CSF doesn't pose a human health hazard, it - very much like African Swine Fever (ASF) - can be devastating to the pork industry.
