Studies in different parts of the world have shown that wine may contain ochratoxin A, a mycotoxin with nephrotoxic and carcinogenic characteristics. The aim of this study was to evaluate the presence of ochratoxin A in wines from different countries, including Brazil, using thin layer chromatography with charged-coupled device technique. The method was sufficiently sensitive for mycotoxin analysis, with mean recovery of 99%. The limits of detection and quantification were 0.2 and 0.4 µg.L- 1, respectively. It was not observed the presence of ochratoxin A in any of the 63 samples analyzed. The low occurrence of this mycotoxin is consistent with similar studies already undertaken and contributes to establish the quality of the wine, especially for the product from southern Brazil; besides ensuring the health of the population consuming these products.
