The aim of this study was to investigate the amount of pesticide residues in fruits and vegetables from South America. A total of 724 samples of 46 different fruits and vegetables from eight South American countries were collected in 2007. In 19% of the samples no residues were found, 72% of samples contained pesticide residues at or below MRL, and 8.4% of samples contained pesticide residues above MRL. Thiabendazole, imazalil and chlorpyrifos were the pesticide most frequently found. Thirty-seven pesticides were found with frequencies higher that 1% in the samples. The results emphasize the need for continuous monitoring of pesticide residues, especially in imported fruits and vegetables.
