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