The amounts of pesticide residue in the samples were detected with LC-MS/MS and GC-MS by taking into consideration the values of tolerance of Turkish Food Codex (TGK). According the results, chlopyrifos residue, which is prohibited, was determined at 34 μg/kg in a sample of orange, 17 μg/kg in a sample of mandarin and 34 μg/kg in a sample of grapefruit that the limit value given as 10 μg/kg in Turkish Food Codex. Diazinon and Pyrimiphos residues, which are prohibited, were also found in the same grapefruit sample as 3 μg/kg and 7 μg/kg levels, respectively. Chlorpyrifos, Diazinon ve Pirimiphos ethyl residues, which are prohibited, were determined at 23 μg/kg, 2 μg/kg and 5 μg/kg levels in a sample of mandarin, respectively. Thiabendazol, which is prohibited, was determined at 7 μg/kg, 31 μg/kg and 31 μg/kg levels in three pieces of examined banana samples. The pesticide residue was not detected in examined kiwi, fresh figs, pomegranates, gold strawberries, pepino, pasiflora samples.
