Analysis of pesticides, veterinary drugs, and environmental contaminants in goat and lamb by the QuEChERSER mega-method

Ederina Ninga et al.

Summary: The analysis of chemical residues in foods is a major challenge for developing countries due to limited resources, but implementing simple multiclass, multi-residue methods in monitoring programs can provide significant benefits. This study investigated a streamlined mega-method for analyzing fatty muscle matrices of goat and lamb, which proved to be an effective and efficient approach to replace multiple methods currently used for the same analytical scope.

High-Throughput Mega-Method for the Analysis of Pesticides, Veterinary Drugs, and Environmental Contaminants by Ultra-High-Performance Liquid Chromatography-Tandem Mass Spectrometry and Robotic Mini-Solid-Phase Extraction Cleanup plus Low-Pressure Gas Chromatography-Tandem Mass Spectrometry, Part 2: Catfish

Ederina Ninga et al.

Summary: This study developed and validated a new method for simultaneous determination of a wide range of veterinary drugs, pesticides, and PCBs in fish, below regulatory levels. The method, named QuEChERSER, was successfully validated for 98% of veterinary drugs and their metabolites, and 91% of pesticides, metabolites, and PCBs, demonstrating its applicability for regulatory monitoring and other purposes in fish analysis.

Validation of a high-throughput method for analysis of pesticide residues in hemp and hemp products

Nicolas Michlig et al.

Summary: The study aimed to evaluate and validate the QuEChERSER method for pesticide residue analysis in hemp, using UHPLC-MS/MS and ITSP+LPGC-MS/MS. The results showed that the method is effective for detecting pesticide residues in different matrices of hemp.
