US and Canada Reports

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)
