A validated chromatographic method was developed for monitoring organochlorine pesticide residues in sesame seeds using QuEChERS sample preparation coupled with gas chromatography–tandem mass spectrometry (GC–MS/MS). The results demonstrate that QuEChERS combined with GC–MS/MS in multiple reaction monitoring (MRM) mode provides a robust, efficient, and reliable chromatographic solution for routine food safety monitoring and regulatory compliance in sesame seed analysis.
