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)

Summary

The survey results represent samples sent in for surveillance testing only and does not include any sample submitted following clinical signs. In the report we discuss preliminary trends of each of these feed ingredients regarding mycotoxin prevalence and contamination levels.
