Mycotoxins in by-products of cereal processing industry

Based on a literature review, it was demonstrated that wheat bran is often more highly contaminated with deoxynivalenol (DON) and zearalenone (ZON) than the original wheat due to higher mycotoxin concentrations in the outer layers of the wheat grain. This is also due to the fact that dust from wheat cleaning is added finally to the bran. Model calculations revealed that care must be taken if contaminated wheat or bran produced from it are used in feeding of pigs, especially in so-called "mycotoxin-years" where higher concentrations of DON and ZON can be expected than in "normal" years.
