Mycotoxins, which are natural toxic compounds produced by filamentous fungi, are considered major contaminants in the food and feed chain due to their stability during processing. Their impacts in food and feedstuff pollution were accentuated due the climate change in the region. They are characterized by their toxicological effects on human and animal health but also by their harmful economic impact. Mediterranean countries: Algeria, Egypt, Libya, Morocco and Tunisia are characterized by high temperatures and high relative humidity, particularly in littoral regions that provide favorable conditions for fungal growth and toxinogenesis. Many scientific papers have been published recently in these countries showing mycotoxin occurrence in different commodities and an attempt at bio-detoxification using many bio-products. In order to minimize the bioavailability and/or to detoxify mycotoxins into less toxic metabolites (bio-transforming agents), safe and biological methods have been developed including the use of lactic acid bacteria, yeasts, plant extracts and clays minerals from Mediterranean regions. The aim of this review is to present the pollution of mycotoxins in food and feedstuff of humans and animals and to discuss the development of effective biological control for mycotoxin removal/detoxification and prevention using bio-products. This review will also elucidate the new used natural products to be considered as a new candidates for mycotoxins detoxification/prevention on animal feedstuffs. [ABSTRACT FROM AUTHOR]
