Abstract

Cereals are one of the strengths of a proper nutritious diet. In fact, the Mediterranean diet considers them the basement of the food pyramid, and it suggests a much wider consumption. Mycotoxins are secondary metabolites produced by fungi, most of which belong to the genus Aspergillus, Penicillium and Fusarium. They are the main cause of contamination of cereal supply chain and they are both produced in the field, before harvest, or during storage in the presence of mechanical and environmental factors influencing fungal growth, including physical damage to the kernels by insects, high humidity and drought. The intake of toxic substances through the consumption of food obtained from the processing of cereals is one of the main and most current problems in the food industry, so, a special attention is given to mycotoxins. Approximately 300 toxins are known today, but the most widespread ones in our territories are five: Aflatoxins, Ochratoxin, Fumonisins and Trichotenes (DON, ZEA). Acute mycotoxicosis can cause damage to many systems of human body such as circulatory, respiratory, digestive, the excretory, the reproductive and the nervous systems. As for chronic mycotoxicosis, the most relevant toxicological aspect is mycotoxins have been directly correlated to extremely potent carcinogens, with the induction of different types of tumours in various organs, including the liver and the kidneys, that are the most affected parts of human body.
