Evaluation of maize contamination by Fusarium and mycotoxins plays an
important role in food safety control systems in the World, including Poland. In
2012 we collected 106 samples grain of 30 maize varieties of different earliness
type (9 early-type FAO 230-240, 9 of medium-early FAO 240-260 and 11 of
medium-late type FAO 260-290) from 10 experimental stations of Research
Centre for Cultivar Testing. Fusarium incidence, species profile and content of
most important mycotoxins : deoxynivalenol (DON) and fumonisins (FUM) were
analyzed. In 33 samples fumonisins level exceeded level 250 ppb (mean value
1210 ppb, maximum 5990 ppb). In 79 samples DON level exceeded 250 ppb (
mean value 560 ppb, maximum 4770 ppb), and in 3 samples DON content was
higher than EU guidance level (1750 ppb). Of 10 experimental stations, most
favorable conditions for both FUM and DON production were found in
Subcarpathian Province, Southeastern Poland. In this region FUM cumulation in
early varieties was lower than in medium-early and medium late ones ( 1060,
1700 and 1580 ppb respectively), whereas DON content ranged from 570 and
660 ppb to 1250 ppb in early, medium-early and medium late types respectively.
Very high variability in mycotoxin content between varieties and locations was
found.
