Table grapes repeatedly highly contaminated

The 34 samples were of 26 green grape varieties and eight samples of red grapes from 5 growing countries. Only one sample from Italy was from organic cultivation, but it contained traces of Metalaxyl and the insecticide active ingredient Chlorfenapyr at the analytical detection limit. The proportion of multiple residues of 88% of all contaminated samples is strikingly high. Due to resistance management, users are forced to use pesticides of different active ingredient classes during the growing season. Even if the prescribed waiting periods before harvesting are observed, the residues from the treatments can be reliably detected. However, it is unusual that a sample from Brazil contained 10 different active ingredients. 

YOUR PLUS: Competent and fast residue analysis for fruit and vegetables is offered by the QS- and BNN-approved AGROLAB food laboratories.
