In 2017, an outbreak regarding the release to the market of contaminated eggs with fipronil, alerted all EU authorities as to monitor and take relevant measures. In Greece, a total of 40 samples of poultry fat and eggs taken from the primary production (poultry farms) were analyzed, as to investigate the occurrence of fipronil residues. For the analysis of the samples, a simple and cost effective sample preparation procedure using freezing as the cleanup step was used, in conjunction with liquid chromatography with electrospray ionization‐tandem mass spectrometry, to identify and quantify fipronil and its sulfone metabolite in poultry fat and eggs. Mean recoveries in the range 69.3–120.3% with all relative standard deviations <18.8% were obtained for both analytes and both matrices. The limit of quantification of the method was set at 0.0025 mg/kg −1 . The matrix effect was evaluated and the quantification of the analytes was conducted using matrix matched calibration standards.
