Los productos agrícolas dominicanos con fines de exportación se analizan constantemente en busca de residuos de plaguicidas. Algunos de estos agroalimentos presentan elevadas concentraciones de plaguicidas que sobrepasan los niveles máximos de residuos establecidos (LMR), convirtiéndose en una preocupación de seguridad alimentaria. El objetivo de este estudio fue identificar la presencia, tipos y concentraciones de 70 residuos de plaguicidas de uso común en el sector hortícola, en dos cultivares de ajíes, mediante la técnica de cromatografía de gases acoplada a espectrometría de masas (GC-MS), en mercados alimenticios seleccionados de la provincia San José de Ocoa y del Gran Santo Domingo. Desde enero del 2018 hasta junio del 2019, se recolectaron 117 muestras de ajíes dulces y estos fueron analizados utilizando la extracción de residuos múltiples QuEChERS, seguida de GC-MS. Se encontró que solo el 62 % cumplía con los LMR, siendo el clorfenapir y la cihalotrina los más frecuentemente detectados (27 y 19 muestras, respectivamente). También, se demostró la presencia de 19 variedades de plaguicidas, entre ellos dos organoclorados no permitidos: dicofol y diclorodifeniltricloroetano (DDT). Los altos niveles y la amplia variedad de residuos de pesticidas detectados en este proyecto sugieren la necesidad de promulgar regulaciones sobre el uso adecuado de pesticidas.
Dominican agricultural products for export purposes are constantly tested for pesticide residues. These agro-foods present high concentrations of pesticides that exceed the established maximum residue levels (MRLs), becoming a food safety concern. The objective of this study was to identify the presence, types and concentrations of 70 pesticide residues commonly used in the horticultural sector in two cultivars of peppers using the gas chromatography technique coupled to mass spectrometry (GC-MS), in selected food markets from the San José de Ocoa province and Gran Santo Domingo. Between January 2018 and June 2019, 117 sweet pepper samples were collected and were analyzed using the QuEChERS multiple residue extraction, followed by GC-MS. It was found that only 62% complied with the MRLs, with chlorphenapir and cyhalothrin being the most frequently detected (27 and 19 samples, respectively). Also, the presence of 19 varieties of pesticides were identified, including two illegal organochlorines: dicofol and dichlorodiphenyltrichloroethane (DDT). The high levels and wide variety of pesticide residues detected in this project suggest the need to enact regulations on the proper use of pesticides.
