The virus is deadly to pigs but harmless to humans.
The department of agriculture has reported the outbreak of African swine flu in the Mpumalanga.
The outbreaks were detected in the country last month, after various diseases attacked livestock in North West.
The two further outbreaks were detected in the central province of Gauteng and Mpumalanga, the department said.
“The affected areas have been placed under quarantine,” the department said in a statement.
“And the provincial veterinary services are applying the necessary disease control measures,” it said, adding it was investigating the source of the disease and what other farms could be affected.
It has spread across China since last year, causing major losses to the world’s largest hog herd.
