A calibration curve using OD values was constructed from five standard concentra-tions between 0.1–6 mg kg−1for FBs, 1–20 g kg−1for AFsand 0.5–10 mg kg−1for DON. The limits of detection were0.1 mg kg−1for FBs, 1 g kg−1for AFs and 0.15 mg kg−1forDON. The mycotoxin concentrations in the samples weremeasured by interpolation from the corresponding calibra-tion curves.
