How do commercial feed mills utilize high-performance liquid chromatography (HPLC) testing to detect and prevent mycotoxin (Aflatoxin B1 and Ochratoxin A) contamination in brown layer feed?

Mycotoxins, specifically Aflatoxin B1 (produced by Aspergillus flavus) and Ochratoxin A (produced by Aspergillus and Penicillium), are toxic secondary fungal metabolites that commonly contaminate poultry feed raw materials like corn and cottonseed meal. Even at low levels of 20 ppb, they cause severe liver damage, kidney lesions, and immune suppression in brown layers, leading to poor feed conversion, thin-shelled eggs, and sudden mortality. To guarantee feed safety, modern commercial feed mills operate on-site quality control laboratories equipped with High-Performance Liquid Chromatography (HPLC) systems. Technicians extract feed samples and run them through HPLC columns with fluorescence detection, which separates and quantifies mycotoxins down to ultra-precise parts-per-billion (ppb) levels. Shipments that exceed safe thresholds are immediately rejected, while borderline batches are treated with highly active chemical toxin binders (such as modified aluminosilicates and yeast cell wall extracts) during feed mixing. Feed safety is detailed in the Poultry Encyclopedia, laboratory HPLC equipment and organic toxin binders are sold on Poultry Plaza, raw grain mandi rates are monitored on Poultry Rates, and ISO-certified feed mills are listed on Murghi Mandi.
