The tomato (Solanum lycopersicon L.) crop has great economic relevance, being one of the most processed agricultural products worldwide. Some pesticides are chemically stable and can remain in food even after processing. In this context, the objective of this work was to analyze food products derived from tomatoes (extract, sauce and ketchup), regarding the levels of pesticide residues. Fifteen samples were acquired from Vale do Jaguaribe, Ceará, Brazil. Six pesticides (bifenthrin, chlorothalonil, chlorpyrifos, cyfluthrin, pyriproxyfen, trifluralin) authorized by Agência Nacional de Vigilância Sanitária (Anvisa) for tomato cultivation were selected for the study. QuEChERS (quick, easy, cheap, effective, rugged, safe) extraction and gas chromatography coupled to mass spectrometry (GC-MS) were used in method validation, according to the recommendations of SANTE 11312/2021 guidelines. Statistical analyses of linearity showed that the six pesticides studied were classified as heterocesdastic. Limits of detection (LOD) and quantification (LOQ) values (0.01-0.03 and 0.03-0.10 mg kg-1, respectively) were below the established maximum residue limits (MRLs) for tomatoes. Accuracy and precision (78-121 and 2.3-16.7%, respectively) were satisfactory. The results indicated that among the 15 analyzed samples, one active ingredient was detected (0.05 mg kg-1) in a tomato sauce sample, lower than MRLs (Anvisa 0.15 mg kg-1 and FAO 0.3 mg kg-1). The results show the relevance of monitoring pesticide residues in tomato-derived products and the validation of new methodologies for food control.
