Mycotoxins in feed: testing, limits and mitigation
Mycotoxins are the single most under-managed feed hazard. A working program combines representative sampling, quantitative testing, ingredient rejection thresholds and validated binders/deactivators — not any one of these alone.

The toxins that matter
Aflatoxin B1, deoxynivalenol (DON), zearalenone, fumonisin B1+B2, ochratoxin A and T-2/HT-2. Multi-mycotoxin exposure is the norm, not the exception.
Sampling
The largest single source of error. Draw 100+ incremental samples from a truck or silo (GAFTA / GIPSA / ISO 24333 protocols) and composite before subsampling to the lab.
Testing options
Rapid lateral-flow strips at intake for high-risk lots; HPLC-MS/MS confirmation quarterly and for disputes.
Mitigation
Rejection thresholds first, then physical cleaning, then binders (bentonite, activated carbon) for polar toxins and deactivators (enzymes, yeast cell wall) for trichothecenes.
