Swine fever outbreak confirmed at pig farm in Gunma
Sep 27, 2020
The agriculture ministry said Saturday that classical swine fever (CSF) infections have been confirmed at a pig farm in the city of Takasaki, Gunma Prefecture, marking the first outbreak of the infectious disease among farmed pigs in the country in about half a year.
It is the first classical swine fever case at a pig farm in Gunma since the first outbreak in Japan in 26 years was confirmed in 2018. The Gunma Prefectural Government will slaughter all of the roughly 5,400 pigs at the farm in accordance with the law.
In the prefecture, vaccinations started for farmed pigs in October last year, following the discovery of an infected wild boar. But the animals found with the disease at the affected farm, all piglets, had yet to be vaccinated...
