Haloxyfop Determination by Gas Chromatography-Tandem Mass Spectrometry in Eggs.

CONCLUSIONS: The determined limit of quantitation was 2.5 ng/g, and the method successfully identified haloxyfop residues in five of six batches of the chicken eggs, with nonzero values ranging from 2.7 to 14.5 ng/g. These values were consistent with flaxseed incorporation into the diet at 4 - 7% and known excretion into eggs at 2-3% of daily haloxyfop exposure, and establish the utility of the method in identifying regulatory noncompliance and adulteration of food sources.
