Each sample was tested for 6 major mycotoxin groups of:

  • A-Trichothecenes (A-Trich): T-2, HT-2, Neosolaniol, Diacetoxyscirpenol

  • B-Trichothecenes (B-Trich): Deoxynivalenol (DON/Vomitoxin), Acetyl-deoxynivalenol, Nivalenol, Fusarenon X

  • Fumonisins (FUM): B1, B2, B3

  • Zearalenone (ZEN)

  • Aflatoxins (Afla): B1, B2, G1, and G2

  • Ochratoxin A (OTA)
