Abstract :In this research work, quality control analyses were conducted in order to monitor and evaluate the validated method for the determination of aflatoxins B 1 , B 2 , G 1 and G 2 in food by using immunoaffinity column and liquid chromatography with postcolumn derivation and fluorescence detection. Quality control analyses used in this study are, duplicate sampling, blank analysis, CRM, RM or QCTM material analyses, spike samples analysis, proficiency testing programs, calibration control and the use of quality control samples & control charts. In addition to these analyses, the OQ-PV test, the homogeneity of sample/sampling procedures, which can be considered as part of quality control analyses have also been used. Private and official food control laboratories should develop inner quality assurance programs for their validated methods and constantly monitor whether these programs have been functioning as specified. At the same time, as provided by the article 5.9 of TS EN ISO/IEC17025 all laboratories must also develop quality control systems in order to monitor the validation of methods and testing. At the same time, they should participate in proficiency tests from time to time.
