Distribution is extremely heterogeneous
Mycotoxin contamination occurs in hot spots. Most of the total error in a mycotoxin result comes from sampling, not from the laboratory. A statistically valid incremental sampling plan is more important than the analytical method chosen.
Screening versus reference methods
Lateral flow and ELISA are appropriate for intake screening and are fast and inexpensive. LC-MS/MS is the reference for contractual disputes, regulatory positions and multi-toxin profiles, including masked and emerging toxins.
Limits are species- and jurisdiction-specific
Legal maxima and guidance values differ between destination markets and between target species. The binding limit is the one in force where the feed will be fed, which is not necessarily where it was bought.
常见行业参考值
| Aflatoxin B1 | Strict statutory limits, dairy especially | Carry-over into milk as M1 |
| DON (vomitoxin) | Swine highly sensitive | Palatability and intake effects first |
| Zearalenone | Reproductive impact in swine | Gilts most sensitive |
| Fumonisins | Equine and swine sensitive | Maize and maize by-products |
Indicative industry reference values for orientation only — always contract against the delivered lot.

常见问题
Do binders remove the need for specification limits?
No. Binders and modifiers are a mitigation tool with toxin-specific efficacy. Contractual limits, sampling discipline and storage control remain the primary defence.

Moisture is water content expressed as a percentage; it dilutes every other nutrient, drives mould and mycotoxin risk in storage, and is the single most disputed parameter in bulk feed trade.
Sampling is the largest source of error in feed-ingredient testing; a valid result requires many small increments combined into a representative composite, taken to a written plan.
Microbiological specifications control Salmonella, Enterobacteriaceae, moulds and yeasts, protecting animal health, plant hygiene and — for several species — the human food chain.
Feed materials must comply with the rules of the country where the feed is fed — covering permitted materials, additive authorisations, contaminant maxima, labelling and species restrictions.
