Mycotoxins are a severe problem in the animal feed industry, as 25% of the world grain is contaminated with one or more mycotoxins. Besides the suffering of the animals, great economic losses are the consequence. Many companies therefore often mycotoxin binders, products that absorb these toxins from the feed. Most of these mycotoxin binders are based on clay. Also organic acids are often added to the feed to kill or inhibit the growth of mycotoxins (because of the reduction on pH).
