Japan’s outbreak of classical swine fever (CSF), or hog cholera, has spread to five prefectures, including Osaka, since the country reported the disease Sept. 9. Until then, the country had not reported a case of CSF for 26 years.
More than 15,000 pigs will be culled and buried as part of measures to prevent further contagion, the government said Wednesday.
In December, the first farm in the Gifu prefecture, reported the disease and culled 610 pigs at the farm. In January, the sixth case was reported, and the country sent additional 1,600 ground self-defense force troops to the farm to bury the pigs.
Pigs shipped from the farm in Aichi to pig farms in Osaka and three other prefectures were also found infected with CSF.
“In order to prevent the disease from spreading further, the government will do its utmost by having the agriculture ministry and relevant local authorities cooperate for speedy and thorough implementation of quarantine measures,” Chief Cabinet Secretary Yoshihide Suga said in a news conference, Reuters reports.
Wild boars are suspected to be the source of hog cholera infections, but local farmers are asking for widespread vaccinations.
This is a different strain from the deadly African swine fever sweeping through China. Swine fever is often deadly for pigs and wild boars, but is not infectious for humans.
