This study was performed to evaluate antimicrobial resistance of food-borne pathogens isolated from retail meat in Korea. A total of 157 samples of beef, pork, and chicken were collected and analyzed for E. coli, Salmonella, Campylobacter. Resistances to tetracycline were declined in accord with reduced usage of tetracycline in live stock production. E. coli stains from chicken meat had higher multi-drug resistance ratio than strains from other meat. One extended spectrum beta lactamase (ESBL) producing E. coli and two ESBL producing Salmonella were identified in this study. ESBL producing Salmonella strains were confirmed to carry CTX-M-1 type genes.

New balloon flower (Platycodon grandiflorum) variety, ‘Jangbaek’, had been developed by pureline selection from some native cultivars collected in Milyang by the medicinal crops research team of the National Yeongnam Agricultural Experiment Station at 200

A new soybean variety “Geomjeongkong 3” was released by the National Crop Experiment Station, RDA, in 2001. This variety was derived from the cross between Shinano-kuro and SNU78010, the elite breeding line with large seed, in the summer season, 1990. The
