Short description of the discussion topic:   

The method of sampling plant commodities for the determination of pesticide residues has been established. The purpose of the method was compliance assessment of fruit and vege-table samples taken in primary production with the requirements of EU Regulation 396/2005.The sampling protocol was designed to overcome the problem of high variability of pesticide content in berries grown in large orchards. Two samplers sampled strawberries in eight fields. The fully ripe berries were selected by walking a W shape through each field. A duplicate sample was taken for each field in a way that represented the variation that could occur due to the ambiguities in sampling protocol. The pesticide content in the sam-ples was determined by a standard accredited method in accordance with HRN EN 15662:2018. The reproducibility of the sampling was calculated from the obtained results and the measurement uncertainty was estimated.
