Fumonisins are thermostable toxins produced by Fusarium spp. These fungi commonly contaminate corn and other types of cereal; nevertheless, they rarely contaminate hay, and when contamination occurs, it is uncommonly a toxic strain. These mycotoxins were first described by a study group in South Africa after 20 years of searching for the substance produced by F. moniliforme that causes leukoenc...

Mycotoxins are secondary metabolites produced by fungi on almost all agricultural crops. Mycotoxin contamination of crops may cause economic losses at all levels of food and feed production. Mycotoxins are known to be either carcinogenic (e.g., aflatoxins, fumonisins), dermatotoxic (deoxynivalenol), neurotoxic (fumonisins), estrogenic (zearalenone) or immunosuppressive (aflatoxins, deoxynivalen...

Mycotoxins are secondary metabolites of fungi that grow on a variety of grains, feedstuffs and animal feed. Feed containing moderate to high levels of mycotoxins cause clinical symptoms in most animals, ranging from organ damage to acute mortality. Consumption of low levels of contaminated feed may result in subclinical problems such as immunosuppression. More than 500 mycotoxins have been iden...

BACKGROUND Fumonisin B1 (FB1), fumonisin B2 (FB2), and overall mycotoxins feed contamination may cause several effects on crops production and animal health. The contamination occurred predominantly in corn and corn-based foods and feeds. AIMS This survey intends to provide the occurrence of fumonisins in swine and equine mixed feeds in Portugal, making an overview from 2007 to 2010. METHOD...

Mycotoxins are naturally occurring toxic substances in foods, posing considerable health risk to humans. Microbiological decontamination of mycotoxins using microorganisms is one of the well-known strategies for the management of mycotoxins. Numerous organisms, including bacteria, fungi and yeasts have been tested for their ability in reducing mycotoxigenic fungi and resultant mycotoxin contami...

Fumonisin B1 (FB1) and FB2 were isolated from corn cultures of both Fusarium moniliforme and Fusarium proliferatum. Respective concentrations in culture materials of FB1 and FB2 ranged from 960 to 2,350 and 120 to 320 micrograms/g for F. moniliforme and from 1,670 to 2,790 and 150 to 320 micrograms/g for F. proliferatum. Thin-layer chromatography, gas chromatography-mass spectroscopy, high-perf...
