A proficiency test (PT) for the determination of copper and zinc in compound feed was organised by Wageningen Food Safety Research (WFSR) between January and May 2021 in accordance with ISO/IEC 17043. WFSR is accredited for the organisation of proficiency tests in the field of contaminants, pesticides, mycotoxins, plant toxins and veterinary drugs in feed and feed ingredients according to ISO/IEC 17043 (R013). The primary goal of this proficiency test was to give participants the opportunity to evaluate and demonstrate their competence for the analysis of copper and zinc in compound feed.
