Preliminary survey of aflatoxins and ochratoxin a in dried fruits from Iran.

Forty five dried fruits, 30 dried apricots and 15 prunes were tested for aflatoxins and ochratoxin A contamination utilizing immunoaffinity column clean up and high performance liquid chromatography (HPLC) with fluorescence detection. 30% and 3.33% of examined apricot samples and 13.33% and 20% of examined prunes samples contained aflatoxin B(1) and ochratoxin A more than 0.2 ng g(-1). The average recoveries were found to be 91.1% and 98.5% for aflatoxin B(1) and ochratoxin A, respectively, while the detection limit was 0.2 ng g(-1) for both mycotoxins.
