Economic adulteration follows price
Adulteration concentrates in high-value ingredients: marine proteins, amino acids, vitamins and premix components. When a market tightens, non-protein nitrogen, mineral fillers and substituted species become the risk to design for.
Microscopy is still the most cost-effective screen
Feed microscopy identifies hulls, shells, soil, urea crystals, foreign seeds and unexpected animal material quickly and cheaply, and it is admissible evidence in most claim processes. It complements, rather than competes with, instrumental methods.
Qué verificar
- —Foreign matter and admixture limits in the contract
- —Microscopy on the retained sample for high-value ingredients
- —Species identification where regulatory species bans apply
- —Acid-insoluble ash as a soil and sand indicator
Riesgos habituales
- —Regulatory non-compliance on prohibited materials
- —Nutrient dilution
- —Equipment damage from stones and metal
Errores frecuentes
- —Relying on visual inspection of a single bag
- —Skipping retained samples, which removes any basis for a later claim
Preguntas frecuentes
How do buyers detect economic adulteration?
By combining an unexpected analytical pattern — protein that does not match amino acids, ash that does not match calcium — with microscopy and, where warranted, targeted instrumental confirmation on a properly retained sample.

Ash is the inorganic residue after complete combustion; it indicates total mineral content and, in protein meals, is a practical marker for bone, shell, sand or mineral adulteration.
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.
Independent verification means testing the delivered lot at an accredited third-party laboratory using the contractual reference methods, on a properly drawn and retained sample.
