Extensive use of pesticides in agriculture can lead to contamination of fruit harvests and an increased risk of toxic effects on humans. A total of 123 fruit samples harvested in 2012 in the north-eastern region of Poland were analysed for pesticide residues as part of the national monitoring programme, and as part of research commissioned by private customers. Pesticide residues were found in 64.2% of the samples. There were pesticide residues below the maximum residue level (MRL) in 63 (51.2%) of the samples, while 16 (13%) exceeded MRLs set by Regulation (EC) 396/2005. The gooseberry, currant, and strawberry samples showed the most contamination. The most frequently detected pesticides were dithiocarbamates (54) followed by difenoconazole (22), boscalid (17), and alpha-cypermethrin (15). More than half of analysed samples had multiple residues (up to 8 residues), with multiple residues most common in gooseberry and currant samples. This study shows cases of non-authorised pesticide use by farmers who are trying to protect certain fruit.
