Level of Pesticide Contamination of Pineapple Fruit in a Region of the Côte d’Ivoire

This study focused on the analysis of 90 pineapple fruit samples, carefully collected during two field campaigns in three areas of the Adiaké department. The aim was to identify and quantify the pesticide residues present in pineapple fruit from these areas. The samples were prepared and analysed using a Shimadzu high-performance liquid chromatography system. The results revealed that the pineapple fruit was contaminated by several pesticides. The calibration curves showed excellent linearity and good reproducibility, with average correlation coefficients (R2 ≥ 0.996). Substance recovery ranged from 60 to 115%. Twelve pesticide residues were identified, including glyphosate, aldicarb, profenofos, metazachlor, cypermethrin, deltamethrin, lambda-cyhalothrin, isoproturon, cyanazine, prometryn, monuron and buturon, with concentrations ranging from 0.002 to 0.01 mg/kg. Glyphosate had the highest concentration, at 0.01 mg/kg. However, it should be noted that the levels of pesticide residues present in pineapple fruit from the three localities remain below the standards set by the FAO/WHO. As a result, pineapple fruit from these areas could be considered compliant with international food safety standards.
