  1. A ‘high DON diet’ predominantly consisting of contaminated cereals was consumed during days 3–6 while days 1–2 and 7–8 were clearing periods.
  2. aDaily DON intake without taking masked forms (3-acetyl DON, 15-acetyl-DON, DON-3-glucoside) into account.
  3. bExpressed as DON equivalents.
  4. cExcretion rate was calculated as follows: Excreted quantity DON-3-sulfate in μmol/DON intake in μmol * 100.
