Pesticide Residues
Despite strict regulation, the use of pesticides can sometimes lead to the contamination of grape juices [Ae1] and wines by residues with toxicological risks that are relatively high for the consumer.
In order to ensure food safety, European Regulation 396/2005/EC, applicable from September 1st, 2008 sets a Maximal Residual Limit (MRL) for pesticides for many food products, including grapes. A MRL has not yet been fixed by the European Community for wine, and therefore, it is accepted that the MRL for wine is the same as the one for grapes. However, some countries have already set a MRL for certain pesticide residues.
Why measure pesticide residues?
According to the European surveillance programme, on 24 tested food products, grapes are in 4th place for the greatest number of MRLs exceeded. In addition, France represents the leading European country using phytosanitary products. Thus, although no actual toxicological risk is associated with the presence of pesticide residues in wines, this problem is still a major concern for consumers.
In addition to requiring a certificate of analysis for export in some countries, as well as for releasing the product on the market, the determination of pesticide residues in wine is interesting for several practical and commercial reasons. It can be used to: Verify and ensure good practices concerning the phytosanitary treatment of vines Optimize the management of treatment programs (molecules, number of applications, etc.) Ensure the food safety of the finished wine Inform and reassure the consumers.
The SARCO offer Analytically speaking, more than 400 molecules associated with pesticide residues can be determined. Nevertheless, the study of the different selection criteria (active molecules allowed on the vine, renewal of approvals, grape to wine transfer rate) and the frequency of detection of these molecules in wines published in recent years (IFV pesticide mapping, PAN-EUROPE study, etc.) allows us to propose an extremely powerful method to simultaneously determine the key molecules that can be found in wine with a detection level below the allowable limits. With this very fast method we provide a result within 2 days.
