Aflatoxins (AF) and ochratoxin A (OTA) are frequent contaminants of foodstuff and low doses of these mycotoxins have been shown to co-occur in baby foods. Our objective was to investigate whether a combined intake of AFM1 and OTA could alter the cytotoxic and genotoxic effects of the single mycotoxins. These effects were assessed by the Neutral Red and the Comet assays, following exposure of Caco-2 cells to individual and combined doses of the two mycotoxins. A dose-dependent cytotoxic response was observed for OTA, whereas AFM1 was cytotoxic only at the highest dose (10BM). Among the several combinations of OTA (2.5, 5 and 10BM) and AFM1 (0.5, 1, 2.5, 5 and 10BM) tested for cytotoxicity, some displayed interactive effects. Noteworthy, combination of 2.5 BM of OTA and 0.5 BM of AFM1, significantly increased the cytotoxicity, as ...
