    Over time, agricultural practices have evolved from traditional methods based on natural elements (water, sunlight, soil, manure) to industrial agriculture employing new technological resources, such as machinery and increasingly sophisticated chemical products. Consequently, pest control methods have also changed, with some farmers using pesticides that eliminate any type of pest. However, the indiscriminate use of these substances is causing contamination of water, soil, and food due to pesticide residues. The present research aimed to determine the presence of organophosphorus pesticides in Solanum tuberosum L. var. Yungay (“potato”). Samples were collected in January 2015 at the wholesale market of Santa Anita, located on Av. La Cultura, district of Santa Anita. A total of 10 samples of 1 kg each of Solanum tuberosum L. var. Yungay (“potato”) were collected equitably from different potato stalls according to the distribution map of the market. All safety measures were taken during transport to SENASA for subsequent analysis by the GC/MS method. The results showed traces of the pesticide Fipronil in one of the samples, with a concentration of 0.002 mg/kg, corresponding to 10% of the samples. It was concluded that this concentration does not exceed the maximum residue limit established by the FAO.
