Natural occurrence of aflatoxins and cyclopiazonic acid (CPA) contamination in peanuts was investigated. Co-occurrence of CPA and aflatoxins was detected in two of 50 samples analysed. The levels of these toxins found in positive samples were 4300 and 493 μg kg-1 for CPA, 625 and 435 μg kg-1 for aflatoxin B1 (AFB1), and 625 and 83 μg kg-1 for aflatoxin G1 (AFG1), respectively. Levels of CPA contamination in the positive samples were similar to those registered in other substrates. This is the first report of natural co-occurrence of CPA and aflatoxins in Argentina.
