This study verified the origin of 346 defatted Korean and non-Korean pork samples via trace elements profiling, and C and N stable isotope ratios analysis. The analyzed elements were ⁶Li, ⁷Li, ¹⁰B, ¹¹B, ⁵¹V^{, 50}Cr, ⁵²Cr, ⁵³Cr, ⁵⁵Mn, ⁵⁸Ni, ⁶⁰Ni, ⁵⁹Co, ⁶³Cu, ⁶⁵Cu, ⁶⁴Zn, ⁶⁶Zn, ⁶⁹Ga, ⁷¹Ga, ⁷⁵As, ⁸²Se, ⁸⁴Sr, ⁸⁶Sr, ⁸⁷Sr, ⁸⁸Sr, ⁸⁵Rb, ⁹⁴Mo, ⁹⁵Mo, ⁹⁷Mo, ¹⁰⁷Ag, ¹⁰⁹Ag, ¹¹⁰Cd, ¹¹¹Cd, ¹¹³Cd, ¹¹²Cd, ¹¹⁴Cd, ¹¹⁶Cd, ¹³³Cs, ²⁰⁶Pb, ²⁰⁷Pb, and ²⁰⁸Pb. Content (mg/kg) of ⁵¹V (0.012), ⁵⁰Cr (0.882), ⁷⁵As (0.017), ⁸⁵Rb (57.7), and ⁸⁷Sr (46.3) were high in Korean pork samples whereas ⁶Li, ⁷Li, ⁵⁹Co, ⁵⁵Mn, ⁵⁸Ni, ⁸⁴Sr, ⁸⁶Sr, ⁸⁸Sr, ¹¹¹Cd, and ¹³³Cs were found higher in non-Korean samples. The results of discriminant analysis showed that the trace elements content and stable isotope ratios were significant for the discrimination of geographical origins with a perfect discrimination rate of 100%.
