This study was designed to investigate the occurrence and exposure assessment of multiple mycotoxins in corn-based food products from Shandong Province, China. Results demonstrated that the mean level of total mycotoxins in test samples was 197.2 mu g/kg. The most frequently found mycotoxins were deoxynivalenol (96.7%) and fumonisin B-1 (94.4%), with mean contamination levels of 65.24 and 128.2, respectively. Among these corn-based food products, thin corn pancake had the highest mean contamination (886.7 mu g/kg), followed by wotou (143.7 mu g/kg), corn cake (135.4 mu g/kg) and mantou (63.73 mu g/kg). The average exposure values to total fumonisins and deoxynivalenol were 0.05 and 0.02 mu g/kg bw/day, which were lower than the provisional maximum tolerable daily intake values of 2 and 1 mu g/kg bw/day, respectively, as established by the Joint FAO/WHO Expert Committee on Food Additives. In the future strict control and systematic monitoring are needed to secure food safety and human health.
