Abstract BACKGROUND Maize is one of the most important cereals worldwide used for different purposes and industries. This cereal is prone to contamination with mycotoxins, such as zearalenone (ZEN) produced mainly by Fusarium graminearum, F. culmorum and F. equiseti. Toxin production under high moist conditions (aw > 0.95) is optimized with temperature alternations between low (12‐14°C) and...

Abstract Mycotoxins are difficult to monitor continuously, and a tool to assess the risk would help to judge if there is a particular risk due to the inclusion of certain feed ingredients. For this, the toxin contents of 97 commercial fish feeds have been estimated, and the most prominent toxins in fish feed are calculated to be deoxynivalenol, zearalenone, fumonisins and...
