 Mycotoxins pose a significant threat to the global feed supply chain with potential economic and trade implications. Research has found that many feed samples contain multiple mycotoxins at low concentrations, which can lead to adverse effects on animals when combined through synergistic or additive interactions. Additionally, mycotoxins are often concentrated into fractions that are commonly used as animal feed, leading to potentially dangerous levels of exposure. To mitigate this risk, it is important to understand how mycotoxins partition during food processing so that feed managers can conform to legislative requirements and minimize the risk of severe market and trade disruptions. Rapid testing methods should also be developed to quickly identify and quantify mycotoxin levels in feed. This article was authored by Luciano Canati, Matteo Aduboni, Carlotta Giromini, and others.
