The biological activity of mycotoxins ranges from weak and/or sometimes positive effects, such as antibacterial activity (see penicillin derivatives derived from Penicillium strains) to strong mutagenic (e. g. aflatoxins, patulin), carcinogenic (e. g. aflatoxins), teratogenic, neurotoxic (e. g. ochratoxins), nephrotoxic (e. g. fumonisins, citrinin), hepatotoxic, and immunotoxic (e. g. ochratoxins, diketopiperazines) activity. Nowadays, many laboratories around the world are specialized in the detection of mycotoxins in food products and contaminated material found in housing. In this volume, a focus on the most important classes of mycotoxins is provided and their chemistry of the last ten years is discussed. In each Section, the individual biological impact is outlined. Sections are arranged according to mycotoxin classes (e. g. aflatoxins) and/or structural classes (e. g. resorcinyl lactones, diketopiperazines). The biology of mycotoxins is also described.

This new book presents the most important data relating to mycotoxins giving basic information on their taxonomic classification, production and biosynthetic pathways, physical and chemical properties, biological effects and biochemical modes of action as well as the threat they pose to animal and human health. The first six chapters present general discussions involving toxigenic fungi and their toxins, the chief biosynthetic pathways of mycotoxins, their biological activities, modes of action, structure-activity relationships, and environmental aspects of mycotoxins and mycotoxicoses. More than 200 individual mycotoxins are then described in detail in the remaining twelve chapters. Extensive tables and indexes as well as a full bibliography for each chapter make this an invaluable reference text. The book is written for students and researchers in the fields of microbiology, mycology, biochemistry, chemistry of natural products, toxicology, pharmacology, human and veterinary medicine, food and agriculture, and environmental sciences.

Abstract: The toxic products from moulds, mycotoxins, are a serious and environmental hazard. They cannot be entirely eliminated. Study of fungal toxins began with the discovery of Aspergillus flavus (parasiticies). Naturally occuring aflatoxins are found in groundnuts, cereals, cotton-seed, and meat and dairy products. The toxins may be synthetically produced. The chemistry and biological assay of toxins are discussed. The toxins produce tumors and biochemically affect nucleic acid and protein synthesis. Control of aflatoxins is possible through mould prevention by control of crop contamination, harvest precautions, and screening. Foods may be detoxified by: 1) removing toxin by extraction; 2) destruction of toxin in situ through heat, radiation, biological degradation, or chemical inactivition. The simplest, most cost-effective method of preventing aflatoxins is by preventative use of good, agricultural methods.

A mycotoxin is a toxin produced by a fungus under special conditions of moisture and temperature. These fungi are aerobic and microscopic and, moreover, may colonize many kinds of food from the field to the table. Mycotoxins are not only a spoilage issue for food, but in high doses can be a serious health threat for humans. The book will be similar to Weidenborner’s previous two books - “Mycotoxins in Feedstuffs” and “Mycotoxins in Foodstuffs” - in that it will be a review of the literature to create a comprehensive reference for mycotoxin levels. It will be his third (and last) book on the topic, this time focusing on the incidence of a mycotoxin in humans and/or animals (natural or artificial incidence). Each entry will include contamination, concentration rate, mean concentration of organs (humans and animals) with a mycotoxin, as well as sample constitution (where possible) and country of origin of the sample.

An indispensable reference, this book provides an overview of the main mycotoxins in food. It is the first complete reference dedicated to toxin producing fungi in foodstuff. The book lists the degree of contamination, concentration of the toxins, and the country of origin and/or detection for each case of contamination presented in the book. Moreover, the book discusses whether a foodstuff is predisposed for mycotoxin contamination. It is written for professionals in the food industry, agriculture, control agencies, food processing, food chemistry, microbiology, and mycology.

The first book to cover this fast developing field, Masked Mycotoxins in Food will provide a full overview of the issues relating to the toxicology of masked mycotoxins present in food products. Mycotoxins are naturally occurring chemicals produced by moulds that can grow on crops and foodstuffs. Masked mycotoxins are modified mycotoxins, due to this modification many cannot be detected using standard analytical techniques, for example HPLC and ELISA, and further research is needed to understand the health risks and threats from these modified compounds.Masked mycotoxin research is an area of toxicological research that has gained significant interest and momentum in recent years. The aim of this book is to provide a full picture of the topic, from the masked mycotoxin formation in plants to their catabolic fate in humans. The book also provides new insights and will highlight possible gaps in the knowledge base of this relatively new area. Edited and written by World renowned experts working within the field, this book is of interest to toxicologists and biochemists, but also food scientists and agricultural researchers working in industry and academia.

Control of Mycotoxins provides information pertinent to the fundamental aspects of the control of mycotoxins. This book provides a review of the toxicology of aflatoxins in the food industry. Organized into 13 chapters, this book begins with an overview of the significant association between tumor-bearing and alpha-foetoprotein when a sensitive immunoautoradiographic method was used. This text then examines the methodology of assay of aflatoxins in food and feed products, as well as their application to the control of mycotoxins. Other chapters review some areas of research at the Northern Regional Research Laboratory involving the effects of insecticide treatment of sterile and unsterile wheat on the formation of aflatoxin and ochratoxin. This book discusses as well the methods for the extraction and determination of aflatoxins from cereals. The final chapter deals with the toxicological study of Fusarium toxicoses. This book is a valuable resource for chemists, microbiologists, biologists, toxicologists, nutritionists, scientists, and veterinarians.

Mycotoxins are secondary metabolites produced by fungi in a wide range of foods (cereals, peanut, tree nuts, dried fruits, coffee, cocoa, grapes, spices...) both in the field and after harvest, particularly during storage. They can also be found in processed foods of plant origin, or by transfer, in food products of animal (milk, eggs, meat and offal). Mycotoxins are of major concern since they can cause acute or chronic intoxications in both humans and animals which are sometimes fatal. Many countries, particularly in Europe, have set maximum acceptable levels for mycotoxins in food and feed. The book reviews the latest literature and innovations on important aspects of mycotoxins, e.g. mycotoxin producing fungi and the related ecosystems, mycotoxin occurrence, toxicity, analysis and management. Quantitative estimations of impacts of climate change on mycotoxin occurrence have been made recently, using predictive modelling. There is also a growing interest in the occurrence and toxicity of multiple mycotoxins in food and feed, including emerging or modified forms of mycotoxins. Innovative tools were also developed to detect and quantify toxinogenic fungi and their toxins. In order to reduce the use of chemicals that are harmful to the environment and health of consumers, alternative methods of prevention and decontamination of mycotoxins were tested in pre- and post-harvest, using microorganisms, natural substances or radiation treatments.
