Residual levels of pesticides in filet green beans from Souss-Massa, Morocco

A total of 30 samples of filet green beans ( Phaseolus vulgaris ) from various popular markets in the Souss-Massa region (Morocco) were analyzed during 2021 for the presence of pesticide residues. We performed a QuEChERS extraction (Quick, Easy, Cheap, Effective, Rugged, and Safe) combined with Liquid Chromatography-Mass Spectrometry (LC–MS/MS) and Gas Chromatography-Mass Spectrometry (GC–MS/MS). The method was validated in accordance with SANTE 11312/2021 guidelines. The results of this survey indicated that 8 out of 30 green bean samples are positives (0.015 to 0.112 mg/kg). Azoxystrobin was the most frequently detected pesticide, occurring in 5 samples. For authorized pesticides, none of the samples exceeded the European Maximum residue level (EU MRL) in green beans, but residue of fipronil-unauthorized substance was detected in one sample at 0.027 mg/kg. Hence, it is important to increase inspections for locally marketed fresh green beans and align agricultural practices with regulatory requirements.
