dc.description.abstractMycotoxins are secondary metabolites of fungi that cause toxic and carcinogenic outcomes in humans exposed to them1. Mycotoxins affect several commodities including cereal grains and their finished products, infant formula and baby foods2. This study aimed to determine the incidence and levels of 20 mycotoxins and metabolites (AFB1, AFB2, AFG1, AFG2, AFM1, OTA, NIV, NEO, DAS, FUS-X, DON, 15-AC-DON, 3-AC-DON, HT-2, T-2, VER, T-2 TETROL, T-2 TRIOL), in breakfast cereals and cereal based baby foods available in the Portuguese market, and compare the results with the maximum limits established by the EU. Breakfast cereal samples (n=26), including corn, wheat, oat, rice and multigrain, and twenty cereal based baby foods (n=20) were collected from supermarkets in Lisbon region and analyzed by HPLC-FLD, LC-MS/MS and GC-MS. Results showed that 88 % breakfast cereals samples and 50 % of cereal based baby foods were contaminated with mycotoxins (with values above the detection limit), although all samples presented levels below the maximum limits established by the Commission Regulation 1881/20063. Regarding breakfast cereals samples, OTA and DON were the most commonly detected mycotoxins, with 88% and 73% of samples revealing values above the LOD, respectively. The co-occurrence of different mycotoxins in the same sample was observed in 92% of the analyzed samples. From these, 46% include mixtures of 3 or 4 mycotoxins. Regarding cereal based baby foods, OTA and AFM1 were the most commonly detected mycotoxins with 50% and 40% of samples revealing values above the LOD. The co-occurrence of mycotoxins was observed in 35% of the analyzed samples. These results are accordingly to those reported by Juan et al (2014)4 and Iqbal et al (2014)5. These results contribute to the increased knowledge on mycotoxin contents in cereal based foods marketed in Portugal, and they highlight the deep need of further studies to overcome the absence of legislated limits for mycotoxins in breakfast cereals other than DON and FB1 and the absence of legislated limits for mycotoxin mixtures in food. The last issue is particularly important considering the potential synergistic effects that could occur between mycotoxins and its potential impact on human and, mainly, children health.pt_PT
