The differences in residue pattern between the main exporters of table grapes to the Danish market, Italy and South Africa, were investigated. The results showed no major differences with respect to the number of samples with residues, where residues were found in 54-78% of the samples. Excedances of EU-MRL were found in five samples from Italy. A number of samples were rinsed to study possible reduction of residues. For copper, iprodione, procymidone and dithiocarbamates significant effect of rinsing was found (20-49% reduction of residues). Significant no-effect was found for OPs and pyrethroids, whereas the number of samples with residues of benzilates, phenylamids and triazoles was insufficient to demonstrate any significant effects. Intake calculation showed that the average intake from Italian grapes was 3.9 µg/day for pesticides and 21 µg/day for copper. Correspondingly the intake from South African grapes was 2.6 and 5.7 µg/day. When the total exposure of pesticides from grapes were related to ADI, expressed as the sum of Hazard Quotients, the exposure were approx 0.5% for Italian samples and 1% for South African samples.
