Description
Summary:Glyphosate (GLYP) is an effective and low-cost broad-spectrum herbicide. However, this herbicide and its primary degradation product, aminomethylphosphonic acid (AMPA), have been linked with adverse human health effects. The global use of glyphosate has significantly increased in recent years, resulting in more direct and indirect human exposure. In this context, GLYP and AMPA are often detected in fresh and processed foods for adults and infants, as well as in drinking water worldwide. Diverse extraction and quantification methods for GLYP and AMPA from foods have been developed. Solid-phase extraction and QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) are the most frequently employed cleanup strategies, while LC-MS/MS is one of the most sensitive and selective techniques for detecting GLYP and AMPA in food products. Although most studies show that GLYP and AMPA concentrations in foods remain within established maximum residue limits, occasionally they exceed legal limits. Thus, the widespread presence of GLYP and AMPA in foodstuffs is a public concern that may lead to consumers exceeding the acceptable daily intake due to prolonged dietary exposure, even if levels remain within thresholds. Therefore, this review explores the different approaches and techniques used in the extraction, detection, and quantification of GLYP and AMPA in foods.
