    Clariant's TOXISORB™ product line is a range of specially developed feed additives that help bind fungal mycotoxins and help prevent them from being resorbed into animals bodies, where they may produce damaging effects. According to the United Nations Food and Agriculture Organization, 25% of feed worldwide is contaminated with different mycotoxins. Mycotoxins are poisonous compounds which are formed by various mold fungi belonging to the species of Aspergillus, Penicillium and Fusarium. These globally found fungi grow on grain and crops and can occur either before/after harvest, during storage, on/in the food itself often under warm, damp and humid conditions.
