Ehime Prefecture announced on the 7th that classical swine fever, a livestock infectious disease also known as CSF, was confirmed at a pig farm in Ozu City. Of the roughly 4,000 pigs being raised there, about 1,500 to 2,000 will be culled. The farm will apply the "selective culling" rule, under which pigs that have been vaccinated against CSF in advance are not culled. This is the sixth outbreak of CSF in Japan this year and the first in the prefecture since 2024. Previously, all pigs at a farm where CSF was detected were culled, but under the selective culling introduced by the revised Livestock Infectious Disease Prevention Act in May, unvaccinated pigs are culled while vaccinated pigs and others continue to be raised, in an effort to reduce the burden on pig farms.
CSF outbreak at an Ehime pig farm triggers culling of 1,500-2,000 pigs, reducing hog supply and weighing on Lean Hog Futures.
