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.
2021 年，对来自摩洛哥苏斯-马萨地区（Souss-Massa）不同热门市场的 30 份青刀豆（Phaseolus vulgaris）样本进行了分析，以检测是否存在农药残留。我们采用 QuEChERS 提取（Quick，Easy，Cheap，Effective，Rugged，and Safe）结合液相色谱-质谱联用（LC-MS/MS）和气相色谱-质谱联用（GC-MS/MS）进行分析。该方法按照 SANTE 11312/2021 指南进行了验证。调查结果表明，30 个青豆样本中有 8 个呈阳性（0.015 至 0.112 毫克/千克）。唑菌酯是最常被检测到的农药，出现在 5 个样本中。对于授权农药，在青豆中没有一个样本超过欧盟最大残留限量（EU MRL），但在一个样本中检测到禁用物质氟虫腈残留，含量为 0.027 毫克/千克。因此，增加对当地市场上新鲜青豆的检查并使农业实践符合监管要求非常重要。
