Mycotoxins, toxic metabolites of molds elaborated during their colonization of foods and feeds, pose a threat to human and animal life. Molds are the diverse group of fungi, which grow in compatatively dry and warm environments, produce copious amount of spores and promote the elaboration of these mycotoxins. Mycotoxigenic fungi, which are unique their sporulating apparatus and exhibit wide variation in their morphology, poses a challenge in their identification. There are numerous examples of their misidentification leading to wrong conclusions. Precise information on taxonomy of these fungi is lacking. Therefore, this book fulfills the need of providing comprehensive information and keys helpful for the accurate identification of these moulds. The book also provides comprehensive account of morphology, mycotoxins produced and factors leading to the elaboration of mycotoxins. Information on their molecular detection, anamorphic and teleomorphic relationships is also included.

Mycotoxins are toxic secondary metabolites produced by fungi. They cause deleterious effects on humans, animals, and plants. More than one hundred mycotoxins are known which contaminate food and feed raw materials. Fungal infection and mycotoxin contamination can occur directly in fields (pre-harvest stage), during storage, or during industrial processing (post-harvest stage). Given the proven toxicity of mycotoxins and their widespread distribution, it is necessary to prevent their occurrence in food and feed. To limit mycotoxin contamination, several techniques can be adopted at the pre-harvest or post-harvest stages. These techniques can reduce mycotoxin concentration through fungal growth reduction or mechanisms leading to mycotoxin degradation or mycotoxin detoxification (i.e., reduction of the toxicity). Until very recently, fungicides were favored to limit mycotoxin contamination by reducing fungal growth. Nonetheless, the sanitary and environmental impacts of these products and their effects on food quality encourage the development of alternative strategies based on biocontrol agents (BCAs) or natural compounds. Moreover, in some cases, fungal growth reduction can stimulate mycotoxin production. The focus of this Special Issue of Toxins is to gather the most recent advances related to reducing mycotoxin contamination in food and feed using BCAs and natural compounds. In this context, two main types of approaches can be proposed: Preventive methods that could be applied in the field, during storage, or during industrial processing and curative methods that detoxify contaminated matrices by eliminating the produced mycotoxin.
