Resumen

Monitoring pesticide use in food is essential for the health safety of consumers so that concentrations above the allowed limits can cause side effects in humans. Hence, the objective of this work was to validate a spectroscopic method for qualitative/quantitative pesticide residues in vegetables through UPLC-ESI-MS/MS, presenting a case study for samples of Trujillo-Peru popular markets. Seven varieties of vegetables were submitted to QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) extraction and evaluated by the validated method. Dimethoate, dissulfoton, methomyl, methylparathion and phorate were above the FAO limits, which highlight the need for suitable measures for pesticide control in foods available to the local population.
