    Mycotoxins are relatively small molecules characterized by a diversity of chemical structure and a diversity of biological activity. They are often genotypically specific for a group of species, but the same compound can also be formed by fungi belonging to different genera. Most of the mycotoxins known have been recognized as metabolic products of Aspergillus, Penicillium and Fusarium species. This review will be focused on aflatoxins, ochratoxins and fumonisins because of their hazard to animal and human health. The production of these mycotoxins have been usually associated with a small number of species but some recent studies have reported the production of these mycotoxins by some other species. These results show that mycotoxin production is broader than is normaly thought, so the possibility can not be ruled out that new species may be a new source of unexpected mycotoxins in their natural substrates.
