Pesticide residue in apples at Czech: do they comply with ´low residue production´ label?

Popis výsledku v původním jazyce

Apples represent an important item in the Czech consumers´ basket, nevertheless, a relatively frequent occurrence of pesticide residues is of concern. Czech producers have been focusing on minimizing residues through ´low residue production´, the practice based, among other factors, on the use of pesticides that rapidly decompose after their application. At present, some retail chains apply for the assessment of fruits / vegetables contamination so called ´action thresholds´, the highest acceptable concentration of pesticide residues in respective commodity not exceeding certain percentage of MRL, e.g., 25%. To obtain up-to-date information about the presence of pesticide residues in locally grown and imported apples and fulfilling MRLs for respective pesticides, we monitored residue profiles in a set of various authentic apple cultivares using both LC-MS / MS and GC-MS / MS methods during the years 2019-2021. 400+ compounds were monitored in this study using optimized method enabling to achieve very low limits of quantification (LOQ) with good repeatability. 265 samples of apples harvested in the Czech Republic were analysed (43.4% of total number of samples) and in other countries 56.6% of samples. Pesticide residues were found in 260 of them (98.10% of tested set). In total, 70 different pesticides were quantified. In general, contamination of apples was relatively low. A positive trend was observed when monitoring action threshold 25% MRL – it was not exceeded in 99.7% of domestic apple samples and in 99.3% of imported ones throughout the observed period. A positive trend was also observed when monitoring action threshold 1%MRL - for domestic apples 51.9% of samples in 2019, 60.7% in 2020 and 62.2% in 2021, respectively and for imported apples 39.7% of samples in 2019, 48.6% in 2020 and 57.3% in 2021).
