Mycotoxins as secondary metabolites produced by fungi are capable of causing disease and death in humans and animals. T-2 toxin is a member of trichothecene mycotoxin. Fusarium sporotrichioides, is the important T-2 toxin production. AFB1 is the strong potent natural carcinogen known, and is usually the major aflatoxin produced by Aspergillus species fungi. In this paper, we reviewed recent studies in different scientific databases including Science Direct, PubMed, Springer, Magiran and Google Scholar for T-2 toxin and Aflatoxin B1 contamination in cereals and cereal based products. According to the result of the study, Aflatoxin B1 and T-2 toxin have been found in cereals and cereal-based products in Iran and worldwide and ELISA and HPLC techniques in determining the range of toxins are mostly used.
