Sensitive and selective analysis of fipronil residues in eggs using Thermo Scientific GC-MS/MS triple quadrupole technology

Pesticides are chemicals used to protect crops and control a variety of pests such as weeds, fungi, rodents, and insects.

Because of their extensive use, pesticides can be found in the air, soils, water, and ultimately in the food chain. Although their use is highly regulated, the misuse of pesticides can lead to unwanted contamination of food and possible health impacts on humans and the environment. An example of such events of pesticide misuse was recently reported in Europe where fipronil, an acaricide authorized to treat pets or selected plant seeds, contaminated a large number of eggs and egg products.

This study demonstrates the excellent sensitivity, selectivity, and linearity achieved for the analysis of fipronil and its metabolites in eggs using the Thermo Scientific™ TSQ™ 8000 Evo triple quadrupole GC-MS system. System performance was tested using full scan acquisition and simple instrumental setup.
