Deoxynivalenol (DON) Testing in Animal Feed
Deoxynivalenol (DON), a mycotoxin produced by Fusarium molds, is one of the most prevalent contaminants found in animal feed. DON can negatively impact livestock health and productivity, leading to economic losses for farmers and processors. At our laboratory, we offer precise and reliable testing services to ensure your animal feed meets safety standards.
Our DON testing process begins with sample collection from various stages of the production chain. Proper sample preparation is critical; this involves homogenization followed by extraction using appropriate solvents. The extracted mycotoxins are then analyzed through a combination of liquid chromatography-tandem mass spectrometry (LC-MS/MS) and enzyme-linked immunosorbent assay (ELISA).
The LC-MS/MS method provides high specificity and sensitivity, allowing for accurate quantification even at very low levels. ELISA is used as a preliminary screening tool due to its simplicity and cost-effectiveness. Once the samples are prepared, they undergo rigorous analysis according to international standards such as ISO 13725 and AOAC International methods.
The results of DON testing are essential for several reasons. They help in maintaining compliance with regulatory limits set by organizations like the European Union (EU) and the World Health Organization (WHO). These limits aim at protecting both animal health and human health downstream when consuming meat or dairy products derived from treated animals.
Our team of experts ensures that all tests comply with relevant guidelines. For instance, EU Regulation 1823/2003 specifies maximum permissible levels for DON in feedstuffs intended for ruminants to prevent them from being fed contaminated material. Similarly, the Codex Alimentarius Commission recommends certain limits based on risk assessment principles.
Our laboratory employs advanced analytical techniques which not only provide accurate results but also minimize false positives or negatives by cross-verifying findings through multiple assays. This approach enhances reliability and trustworthiness of our reports among clients who rely heavily upon these analyses for decision making processes related to quality assurance programs within their organizations.

Why It Matters
The importance of DON testing cannot be overstated, especially considering its potential adverse effects on animal health and productivity. Prolonged exposure to low concentrations can lead to reduced feed intake, weight loss, impaired immune response, and reproductive disorders among livestock animals.
- Health Risks: Chronic consumption of DON-contaminated feeds may result in severe health issues including enterotoxicosis, immunosuppression, and mycotoxic nephropathy.
- Economic Losses: Affected animals often suffer from decreased performance metrics such as growth rates and reproductive efficiency. This translates into significant financial losses for producers and processors alike.
By implementing robust DON testing protocols, our clients can mitigate these risks effectively. Early detection allows for corrective actions to be taken promptly, thereby safeguarding both animal welfare and profitability.
Customer Impact and Satisfaction
- Enhanced Reputation: Providing high-quality feed ensures better animal health outcomes which in turn reflects favorably on your brand reputation.
- Better Decision Making: Reliable test results enable informed choices about raw material sourcing and processing methods leading to improved product quality.
Our customers appreciate the comprehensive nature of our service offering. They find comfort knowing that they are partnering with a reputable institution committed to delivering accurate, timely data crucial for maintaining compliance standards.
Use Cases and Application Examples
- Routine Quality Control: Regular testing ensures continuous monitoring of feed safety throughout the production cycle.
- New Product Development: Incorporating DON tests early in development helps identify potential contamination issues before scaling up operations.
Here are some specific scenarios where our DON testing services have made a tangible difference:
- A feed manufacturer discovered that one of its suppliers was delivering grain containing levels exceeding EU limits. Prompt testing enabled swift corrective measures to be implemented preventing further contamination from entering the supply chain.
- An importer faced concerns about the safety of imported corn shipments due to mold growth suspicions. Our tests confirmed presence of DON at acceptable levels thus avoiding unnecessary rejections and ensuring smooth import processes.
These examples illustrate how our laboratory plays a crucial role in maintaining quality standards across different stages of feed production and distribution.
