Contamination of animal feed with mycotoxins still occurs very often, despite great efforts in preventing it. Animal feeds are contaminated, at low levels, with several mycotoxins, particularly with those produced by Aspergillus and Fusarium genera (Aflatoxin B1, Ochratoxin A, Zearalenone, Deoxynivalenol and Fumonisina B1). In animal feed, to date, only Aflatoxin B1 is limited through EU regulation. Consequently, mycotoxins cause serious disorders and diseases in farm animals. In 2009, the European Union (386/2009/EC) approved the use of mycotoxin-detoxifying agents, as feed additives, to prevent mycotoxicoses in farm animals. The present review gives an overview of the problem of multi-mycotoxin contamination of feed, and aims to classify mycotoxin adsorbing agents (minerals, organic, and synthetic) for feed decontamination, focusing on adsorbents with the ability to bind to multiple mycotoxins, which should have a more effective application in farms but they are still little studied in scientific literature.

Mycotoxins comprise a family of fungal toxins, many of which have been implicated as chemical progenitors of toxicity in man and animals. The most thoroughly studied are the aflatoxins. A variety of physical, chemical, and biological methods to counteract the mycotoxin problem have been reported, but large-scale, practical, and cost-effective methods for detoxifying mycotoxin-containing feedstuffs are currently not available. The most recent approach to the problem has been the addition to the animal's diet of nonnutritive sorbents that sequester mycotoxins and reduce their gastrointestinal absorption, avoiding their toxic effects on livestock and toxin carryover into animal products. This review comments on the in vitro efficacy of several of the adsorbents assayed, and their in vivo applications in a range of animals will be discussed. The sorbents reviewed are activated charcoal, bentonite, zeolite, hydrated sodium calcium aluminosilicate (HSCAS) and a wide variety of clays and synthetic ion-exchange r...
