In 2019, as every year, the Italian National Reference Laboratory for pesticide residues in products of animal origin and commodities with high fat content (NRL-AO) organized in cooperation with the IOC (International Olive Council) a new proficiency test in olive oil named COIPT-19. Laboratories invited to participate in these PTs are Mediterranean laboratories of IOC and European laboratories (NRLs, official control laboratories and private laboratories), involved in the National and European monitoring programs for pesticide residues in food. The exercise consisted in the determination of unknown six different pesticides in a spiked olive oil sample, chosen from a target list of twenty-six compounds. Forty participating laboratories submitted results thirty-five of which analysed all the six spiked compounds. The majority of participants obtained a satisfactory performance (z-score) for all tested pesticides.
