Survey on Ochratoxin A in wines. More data concerning bottled red wines.

Research on Ochratoxin A (OA), the survey on bottled red wines dealt with in a previous note (Bulletin O.I.V., 2001, vol. 74, n° 849-850, pp. 772- 780), has been extended to cover 76 bottled red wines collected on the northern Italian market. The results show that 19 samples had an Ochratoxin A content below the quantitation limit, while, for the other 57 samples, the level of OA ranges between 0.06 and 2.90 μg/L. Taking into account the 94 bottled red wines analysed in this project and in the previous one, the percentage of the samples having an OA content exceeding 0.5 μg/L has been found to be 18%.
