QuEChERS method was applied and validated for the multi-residue analysis of pesticides in eggs and egg
products. The method includes extraction with buffered acetonitrile and clean-up with dispersive sorbents,
followed by LC–MS/MS analysis. The validation parameters were used based on the guideline of
SANCO/12495/2011. Recoveries were within the range of 71–108%, and the relative standard deviations
were 2–13% at the 3 different concentrations evaluated for eggs and egg products. The limits of quantification
for the target compounds ranged from 0.3 to 6 ng/g. Monitoring of 100 domestic eggs and 50
imported egg products were performed to verify the adaptability in real samples. No samples contained
residues exceeding the maximum residue limit (MRL). Carbendazim, dimethoate, and pirimicarb were
each found in egg yolks at the level of 2 ng/g, in the same sample, well below their MRLs of
50–100 ng/g.
