OTA was detected in 69% of the samples; 20% of them were above the EU limit of 3 μg/kg. Twenty percent contained CIT (1.5-42 μg/kg). FBs were detected, not only in cornflakes, but also in products containing oats or rice, in the range 1-1110 μg/kg. Some samples were contaminated by all three mycotoxins.
