EN 17425 Mycotoxin Multi-Residue Testing in Animal Feed
The European standard EN 17425: Determination of mycotoxins and other contaminants in animal feed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) provides a comprehensive framework for the analysis of multiple mycotoxins present in animal feed. This service ensures that feed manufacturers, quality managers, compliance officers, and R&D engineers can reliably detect and quantify mycotoxin residues to meet regulatory requirements and ensure product safety.
Mycotoxins are toxic secondary metabolites produced by certain molds (fungi) under specific environmental conditions. Common mycotoxins include aflatoxins, zearalenone, ochratoxin A, and fumonisins, among others. These toxins can pose significant risks to animal health, productivity, and welfare, as well as human health when consumed through contaminated food products derived from affected animals.
Animal feed is a critical point of mycotoxin contamination in the food chain. Contamination occurs during various stages, including raw material sourcing, processing, storage, and handling. Ensuring that animal feed meets strict safety standards not only protects livestock but also supports sustainable production practices. The EN 17425 standard facilitates accurate detection of a wide range of mycotoxins, providing actionable insights for corrective measures.
The methodology prescribed in EN 17425 leverages liquid chromatography-tandem mass spectrometry (LC-MS/MS), which offers high sensitivity and specificity. This advanced analytical technique allows laboratories to identify and quantify multiple mycotoxins simultaneously, enhancing efficiency and reliability. The standard specifies detailed procedures for sample preparation, extraction, clean-up, and analysis, ensuring consistent results across different batches and laboratories.
Sample preparation is critical in achieving accurate results. Commonly used techniques include solvent extraction, solid-phase extraction (SPE), and QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) methods. Each method has its advantages depending on the feed matrix and mycotoxin type. SPE, for instance, is effective in removing interfering substances, while QuEChERS simplifies sample preparation with minimal equipment.
The LC-MS/MS instrumentation used for this service typically consists of a high-performance liquid chromatograph (HPLC) coupled with a tandem mass spectrometer capable of performing parent ion and product ion scans. This configuration allows the detection and quantification of target mycotoxins based on their unique fragmentation patterns. The system is equipped with automated sample injection, gradient elution, and data acquisition software to streamline the analytical process.
After analysis, results are reported in accordance with EN 17425, providing a detailed breakdown of detected mycotoxin residues. Reporting includes quantitative values for each identified toxin along with their respective limits of detection (LOD) and quantification (LOQ). This information is crucial for making informed decisions regarding feed formulation and quality control.
The service also offers a comprehensive suite of support services, including method validation, training sessions, and consultation on best practices. These resources ensure that clients can confidently implement the EN 17425 standard within their operations, enhancing overall compliance and safety standards.
Why It Matters
Mycotoxin contamination in animal feed poses significant risks to both livestock health and human food security. Aflatoxins, for example, are potent carcinogens that can induce liver damage and reduce immune function in animals. Ochratoxin A is nephrotoxic and immunosuppressive, while zearalenone has estrogenic effects that affect reproductive performance. Fumonisins cause hepatic necrosis and have been linked to cancer.
From a regulatory perspective, the European Union (EU) sets strict limits on mycotoxin concentrations in animal feed through Directive 2018/835/EU, which aligns with Codex Alimentarius standards. Non-compliance can lead to severe penalties and reputational damage for affected companies. By adhering to EN 17425, laboratories ensure that they are meeting these stringent requirements.
For quality managers and compliance officers, the service provides peace of mind by offering reliable data on feed safety. This information is essential for maintaining a consistent supply chain and ensuring product integrity. R&D engineers benefit from detailed insights into mycotoxin behavior in different feed matrices, which can inform formulation adjustments to mitigate contamination risks.
In addition to regulatory compliance, the service supports sustainability initiatives by minimizing the use of substandard raw materials and promoting best practices throughout the supply chain. This contributes to more efficient resource utilization and reduced environmental impact.
