Abstract

This research aimed to quantify the pesticide residues on both maize and faba bean forage crops during the seasons of 2021 and 2022 at the Sides station in Beni Suef Governorate. In addition, the quality of the sampled meat from the buffaloes fed on these forage crops was assessed to determine its content of pesticide residues. After consuming maize and faba beans as fodder, pesticide residues that were transmitted to buffalo meat were observed for 3 consecutive months. Acetone was used for the extraction process. Clean- up of the extracts was accomplished by dividing saturated hexane with acetonitrile. Both Gas Chromatography (GC) with a flame ionization detector and High Performance Liquid Chromatography (HPLC) with an ultra violet detector were used to examine all samples for pesticide residues. Except for methomyl, which was higher than the ADI in all samples of maize and in samples of faba beans taken exclusively during the winter, other pesticides were below the values of the Acceptable Daily Intake (ADI) and the Maximum Residue Limits (MRL). Additionally, between 56% and 67% of the pesticides applied on faba beans and maize during the seasons of 2021 and 2022, respectively, were transmitted to buffalo flesh.
