South Korea has confirmed its fifth African swine fever(ASF) case of the year.

The government said on Tuesday that the latest case was confirmed in the southeastern city of Andong in North Gyeongsang Province at a pig farm raising about 190 pigs. 

This comes just 17 days after a case of ASF was reported in Yeongcheon, in the same province, on June 15. 

The disease control authorities sent an initial response team and epidemiology experts to the Andong farm, implementing control measures such as restricting access to non-farm personnel, livestock and vehicles. The authorities are culling the pigs at the farm as a preventive measure.

The government also issued a 24-hour standstill order from 8 p.m. Tuesday for pig farms and related facilities in Andong and six neighboring cities and counties.
