AOAC 2000.03 Zearalenone Residue Profiling in Maize
The AOAC International method 2000.03 is widely recognized for its accuracy and reliability in quantifying zearalenone residues in maize. This method is particularly significant in the food & feed testing sector, as it ensures compliance with international standards and helps protect public health by minimizing harmful contaminants.
Zearalenone is a mycotoxin produced by fungi such as Fusarium species, which can contaminate crops like maize. High levels of zearalenone in feed can disrupt estrogenic pathways in animals leading to reproductive issues and reduced performance. In humans, it may cause hormonal imbalances similar to those seen during pregnancy.
The AOAC 2000.03 method involves sample preparation through extraction using acetonitrile followed by clean-up on solid phase extraction (SPE) cartridges prior to analysis via high-performance liquid chromatography (HPLC). The HPLC system equipped with a UV detector provides precise quantification of zearalenone concentrations.
This service is crucial for quality managers, compliance officers, R&D engineers, and procurement teams involved in ensuring food safety standards are met. By using this method, laboratories can provide accurate data on the presence and levels of zearalenone which helps stakeholders make informed decisions regarding product release or further processing steps.
The importance cannot be overstated as improper handling could lead to significant economic losses due to recalls or legal actions against non-compliance with regulations. It also aids in maintaining brand reputation by assuring consumers that the products they consume are safe and free from harmful contaminants.
Our laboratory adheres strictly to best practices outlined in the AOAC 2000.03 protocol, ensuring consistent results across all samples analyzed. This commitment translates into trustworthiness and reliability for our clients who rely on us for accurate testing outcomes.
By partnering with us, you gain access to state-of-the-art facilities staffed by experienced professionals dedicated to delivering high-quality services tailored specifically towards your needs in food & feed safety assurance programs.
Why It Matters
The presence of zearalenone in maize poses significant risks both for animal health and human consumption. For livestock, exposure can lead to reduced fertility rates, abortion, stillbirths, and increased mortality among young animals. In humans, chronic ingestion may result in reproductive disorders such as infertility or miscarriage.
Regulatory bodies worldwide have implemented strict limits on permissible levels of zearalenone in food products, including maize used for animal feed. Failure to comply can lead to product recalls, legal sanctions, and damage to company reputation. Thus, rigorous testing is essential not just for quality assurance but also to maintain regulatory compliance.
Implementing the AOAC 2000.03 method ensures that your organization stays ahead of these challenges by providing accurate data on zearalenone levels in maize samples. This information allows you to take proactive measures such as implementing corrective actions immediately or adjusting processing methods accordingly.
Applied Standards
| Standard Number | Description |
|---|---|
| AOAC 2000.03 | High-performance liquid chromatography with UV detection for quantification of zearalenone residues in maize. |
| ISO/IEC 17025:2017 | General requirements for the competence of testing and calibration laboratories. |

The combination of these standards ensures that our laboratory maintains the highest levels of precision, accuracy, and traceability in all our testing procedures.
Scope and Methodology
Our AOAC 2000.03 Zearalenone Residue Profiling service encompasses a comprehensive approach to sample preparation, analysis, and reporting. The process begins with thorough sample collection from the field or storage facility followed by detailed documentation of environmental conditions such as temperature and humidity.
The samples are then transported under controlled conditions to our laboratory where they undergo rigorous quality control checks before being prepared for extraction using acetonitrile. This solvent extracts the zearalenone present in the maize which is subsequently concentrated onto an SPE cartridge.
After elution, the extract is injected into the HPLC system equipped with a UV detector capable of detecting even trace amounts of zearalenone. The retention times and peak areas generated by the instrument are compared against calibration standards to calculate precise concentrations.
The results are presented in a detailed report including raw data, calculated values, and any relevant comments or recommendations based on our findings. These reports serve as valuable tools for decision-making processes related to product release or further processing steps.
