Abstract
The presence of pesticide residues and/or ochratoxin A in wine can affect the health of consumers. Fewwineries have taken control measures or have verified the effectiveness of the control measures they have taken.
It was of interest to evaluate the results for pesticide residues and ochratoxin A in wine samples taken by wineriesor by official inspection bodies.
All analytical results for pesticides and/or ochratoxin A in wine samples taken between 2008 and 2015 and available at the wineries in both districts, or in the official control samples, were considered. All in all, 20 analytical results on pesticide residues and 64 Ochratoxin A determinations.
No results exceeded the maximum limit of pesticide residue onwine grapes, since there is no legal limit onwine. The determination of pesticides in wine only makes sense when concentration or dilution factors during the winemaking process, with regard to the maximum limits of pesticide residueson wine grapes, are justified, but this did not happeninanycase. Two different pesticide residues were found in one sample, and a concentration of 5 mg kg-1 of iprodione (maximum limit of iprodione residue on wine grapes: 10 meaning kg-1) was found in an organic wine sample, which gives an idea of wrong agricultural practices.
No ochratoxin A result exceeded the legal limit for wine of 2 μg L-1(Commission Regulation (EC) No.1881/2006). Concentrations of up to 0.44 μg L-1 were obtained, which shows that ochratoxin A can occur inwine.
Wineries need to define and take effective control measures to deal with these two hazards.
