A total of 1965 fecal samples from pigs from 44 farms nationwide were investigated during 2012-2013 in Korea. Three to four farms per province were randomly selected from all nine provinces of Korea. Altogether, 30 conventional farms and 14 organic farms were studied. Conventional farms were characterized by unrestricted use of antimicrobials for prevention and treatment of diseased pigs at the farm level. Whereas, the organic farms used organic feed and used antimicrobials only on prescription by veterinarians for treatment of diseased pigs.

In each farm, five pig fecal samples per age group were collected. Pigs were selected for sampling at random, and only one isolate per pig was used. The 1965 fecal samples were collected from single animals from pen floor. About 5-10 g of fecal sample was collected from the middle of freshly passed feces with a sterile spatula in 50 ml sterilized polypropylene conical tubes.
