During the period from September to November 2014, occurrences of Aflatoxin B1, B2, G1, and G2 (AFB1, AFB2, AFG1, and AFG2) were determined in 76 pepper samples consisting black pepper (n = 40) and red pepper (n = 36) obtained from local markets of Isfahan province, Iran. Aflatoxins' (AFs') analyses were carried out by using the high-performance liquid chromatography (HPLC) method. AFB1 levels in 32 (88.9%) of 36 red pepper samples were higher than the Iranian and European maximum permitted level (>5 µg/kg). Total AFs were detected in 41 out of 76 samples (53.9%) while 25 pepper samples (32.9%) had levels of the toxin above the Iranian and European permitted level, that is, 10 μg/kg. This study shows that incidence of AFs' contamination in red pepper in Iran was significantly higher than black pepper (p < .05) and indicates a serious hazard for human health.
