Authorities are investigating a suspected case in Naju, 355 kilometres south of Seoul, according to the Ministry of Agriculture, Food and Rural Affairs. The samples were gathered from a slaughterhouse.
The farm had killed all of its 22,000 ducks to be sold at market, but they were discarded after the suspected case.
Another duck farm from the same town confirmed a highly pathogenic bird flu case the previous day. The farm was raising 8,000 birds.
Later in the day, South Korea also identified a separate suspected case from a duck farm in Jangseong, about 310 kilometres south of Seoul.
If both suspected cases are found to be seriously contagious via tests, South Jeolla Province alone would have four confirmed infections.
So far, South Korea has reported seven highly pathogenic avian influenza cases from poultry farms across the country, including two from Gyeonggi Province that surrounds the capital city.
There were also infection cases from North Chungcheong, North Gyeongsang and North Jeolla provinces.
South Korea completed the culling of more than 4 million poultry from affected farms late Wednesday, covering 2.42 million chickens, 1.01 million quails and 572,000 ducks.
Authorities culled poultry within a 3-km radius of infected farms. Birds at farms with suspected cases are also destroyed.
Highly pathogenic avian influenza is contagious and can cause severe illness and even death in poultry.
The country reported its first highly pathogenic case in 32 months in late October in Cheonan, 92 kilometres south of Seoul, from wild birds.
Since then, a total of 22 cases have been found from wild bird habitats across the country, according to the latest data provided by the ministry. Health authorities are investigating more than 10 suspected cases among wild birds.
