Mycotoxins in maize products of the 1994/95 marketing season.

The levels of mycotoxins found were generally lower the more refined the maize products were. The highest levels of deoxynivalenol, nivalenol and fumonisins were found in maize bran and maize screenings. Ochratoxin A was found in a defatted germ meal sample at 50 μg/kg. Zearalenone was found randomly in samples at low levels (50 - 100 μg/kg). All other mycotoxins tested for, except in maize bran and maize screenings, were absent above the detection limits.
