Aim and purpose: To analyse food samples on pesticide residues using multiresidue methods to define which pesticide has the most occurrence in analysed samples and why. Materials and method: Analysed samples were fruit and vegetables taken in official controls. Samples were prepared using Quechers method according to HRN EN 15662/2008 and analysed with GC-MS/MS. Results: In total, 554 samples were analysed using multiresidue method. From 554 samples 13 samples had pesticide residue concentrations above MRL. Pesticides identified and quantified above MRL were Bromopropylate and Chlorpyrifos. Quantified pesticide residues concentrations were in range from 0.026 - 1.35 mg/kg. Samples that contain pesticides above MRL were pear (1), dried wild apples (1) leek (2) and apples (10). Conclusion: It is evident that chlorpyrifos concentrations above MRL occur more than other pesticides. In case of leek manufacturer was using the product with active substance chlorpyrifos wich not complied for usage on leek. In case of dried wild apples manufacturers mix wild apples with conventional ones. The MRL for Chlorpyrifos on apples changed in 2016 from 0, 05 mg/kg to 0, 01 mg/kg. Apple manufacturers didn’t aware about MRL change, or didn’t have proper education on pesticide usage.
