A sixth suspected case of African swine fever was reported early Wednesday in Incheon's Ganghwa County, the same area that the fifth case of the disease was confirmed on Tuesday.
"At 8:05 on Wednesday morning, a suspected case of African swine fever was reported at a pig farm in Ganghwa County, Incheon. The suspected farm is 6-point-6 kilometers away from the farm in Gimpo where the third case of the fever was confirmed."
South Korea's Agriculture Ministry held a press briefing on Wednesday morning, and said it plans to inspect pig farms and livestock related facilities in 154 cities and counties,... in preparation for sterilization.
The ministry on Tuesday issued a 48-hour nationwide standstill for all pig farms, feed factories, and slaughterhouses.
The six tightly controlled zones in northern Gyeonggi-do Province were also expanded to the entire province, the city of Incheon, and Gangwon-do Province.
African swine fever is fatal to pigs, but is harmless to humans.
