In a brutal battle for food and space, two fungal cousins are currently duking it out across the nation's cotton fields. Thanks to biological control strategies developed by the Agricultural Research Service (ARS), the better of these two microscopic relatives is winning. Plant pathologist Peter Cotty, who is part of the ARS Food and Feed Safety Research Unit at New Orleans, La., but is located at the University of Arizona-Tucson, instigated this competition. By pitting a benign strain...

In a previous paper (Spring and Fegan, 2005), we presented information reviewing current knowledge of mycotoxins as they relate to aquaculture species. Since then, awareness of mycotoxin-related issues within the industry has grown as feed manufacturers and producers realize the importance of mycotoxins other than aflatoxin and their potential to impact production as well as the prevalence of mycotoxins in many raw materials. While it remains true that the majority of mycotoxin issues are...

Mycotoxins are a group of structurally diverse secondary fungal metabolites that occur as contaminants of grain worldwide. Aspergillus, Fusarium, Penicillium, and Claviceps species of fungi are ubiquitous in nature and under ideal conditions often infect economically important crops and forages in the field, during storage, transportation and processing. The most important mycotoxins found in the United States are aflatoxin B 1 , fumonisin B 1 , ochratoxin A, vomitoxin,...

Mycotoxins are secondary metabolites secreted by various moulds such as Aspergillus, Penicillium and Fusarium. They are synthesised during the production, transport and storage of food supplies in certain environmental conditions. Detectable levels of nearly 300 potentially toxic metabolites secreted by moulds contaminate 25 to 40% of the cereals and cereal products worldwide (Pittet, 1998; Yiannikouris and Jouany, 2002). Despite recent food crises (e.g., bovine spongiform...

Mycotoxins are secondary metabolites secreted by moulds, mostly belonging to the three genera Aspergillus, Penicillium and Fusarium produced in cereal grains as well as forages before, during and after harvest. Forages and cereals naturally come into contact with fungal spores. The fungal contamination of plants and the biosynthesis of toxins depend on the state of health of the plant before harvest, meteorological conditions, harvesting techniques, delays and hydrothermal...

Grain production in South Africa has undergone major changes over the past 10 years. The major driving force behind these changes has been the deregulation of the grain industries and the demise of the various commodity control boards. The single desk marketing system has been replaced by a free market system in which grain prices are determined by local supply and demand, international grain prices and the respective exchange rates. Grain trading on the Agricultural Futures Division...

The Aflatoxins are a chemically related group of compounds that are important hepatotoxic mycotoxins. They are produced by fungi, and can contaminate several important crops including corn, peanuts, and tree nuts under favorable environmental conditions. These toxins can cause liver disease in humans and animals, a decrease in milk and egg production, and are immunosuppressive, carcinogenic and mutagenic. The most commonly occurring and most potent of the aflatoxins is Aflatoxin B1....

With summer just around the corner, thoughts of another season of drought and in turn the increased presence of mycotoxins are crossing many equine owners' minds. "The global climate change has resulted in climatic extremes which are increasing the frequency of mycotoxin contamination of cereal grains, forages and silages," said Trevor Smith, animal science specialist at the University of Guelph. Plants stressed by drought and high temperatures are commonly invaded by mold spores...

The Indian feed and poultry industry is already aware of the possibility of various mycotoxin contaminations of the feed. This holds true not only for mycotoxins like aflatoxins, but to other mycotoxins as well as ochratoxin A, T-2 toxin, zearalenone,...

Fusarium fungi thrive in temperate climates around the world and Fusarium mycotoxins are the mycotoxins most commonly found in feed grains and forages (Wood, 1992). There are numerous pathologies characteristic of Fusarium mycotoxicoses and this is due to the several chemically distinct groups of Fusarium mycotoxins, which have very different effects on animal metabolism and behavior. Swine are usually considered to be the most sensitive species to feed-borne mycotoxins both with respect to...

As we learn more about mycotoxins and make new discoveries in this area, we begin to realize that there are many unanswered questions involving these toxins. Mycotoxins are produced by molds, which are aerobic unicellular organisms. Mold growth can occur in environments that contain lower available water than would be needed to support bacterial growth. For example, bread will support mold growth but not bacterial growth under normal conditions. Just as there are beneficial bacteria and...

The analysis of mycotoxins has become an issue of global interest, in particular because most countries already set up regulative limits or guideline levels for the tolerance of such contaminants in agricultural commodities and products. Approximately 300 to 400 substances are recognized as mycotoxins, comprising a broad variety of chemical structures produced by various mould species on many agricultural commodities and processed food and feed. Globalisation of the trade of...

Introduction Silages made from a variety of forage crops constitute important components of ruminant diets in many areas of the world. New estimates for Germany, for example, indicate that silage production is the biggest on-farm preservation operation (Weissbach, personal communication). In 2000, a total of 76.2 million tonnes of silage were produced compared to only 2.3 tonnes of hay (based on fresh matter). Maize silage represents the major proportion (about 58%), followed...

Introduction Whether grain is produced in temperate, subtropical or tropical climates, if high rainfall and humidity are experienced in the harvest season, infection of the grain by mould is likely. The range of ingredients affected by mould includes grains, oilseeds, roughages and milling by-products. Where there is mould growth, the likelihood of mycotoxins being present is significant. Moulds are tremendously adaptable organisms, able to metabolise a...

Introduction Mycotoxins are metabolites produced by fungi which are toxic to livestock when consumed in biologically significant amounts. The resulting diseases are referred to as mycotoxicoses. Mold growth and mycotoxin production on feed grains are influenced by many factors but the most important of these is moisture. Stored grains should contain less than 15% moisture to minimize mold growth. Fusarium fungi are commonly found in temperate climates; and Fusarium mycotoxins are...

Introduction Mycotoxins are secondary products of fungal metabolism that may beproduced in contaminated feeds during production and storage. Thesemetabolites are generally associated with a group of ubiquitous fungibelonging to the Fusarium, Aspergillus, Penicillium and Claviceps speciesthat grow on forages and grains in the field and during storage (Ledoux andRottinghaus, 1999). It has been estimated that at least 300 fungal metabolitesare potentially toxic for man and...
