All 209 PCB congeners were analyzed in cheese produced in Korea and Canada. 5 Korean and 10 Canadian cheeses were purchased in supermarket in their native countries. 93 PCB congeners were found in Korean cheese; 83 congeners were detected in Canadian cheese. Total PCB concentrations were 299.81 and 200.96 pg/g w.w. in Korean and Canadian cheeses respectively; PCB concentration was 1.5 times higher in Korean than Canadian cheese. Korean TEQ concentration (0.0067 pg-TEQ/g w.w.) in cheese was similar to in Canadian cheese (0.0064 pg-TEQ/g w.w.). These PCB concentrations range was low level compared with that of other cheeses globally. The correlation coefficient $(R^2)$ of regression was high (0.752) between each PCB congener concentration in both Korean and Canadian cheese.
