Codex STAN 193 General Standard for Mycotoxin Contaminants
The Codex STAN 193 General Standard for Mycotoxin Contaminants establishes limits and guidelines for mycotoxins in foodstuffs and animal feed. This standard aims to protect public health by providing a framework that ensures the safety of food products against these harmful contaminants. Mycotoxins are toxic secondary metabolites produced by fungi, which can contaminate crops during growth, harvest, or storage.
Food & Feed Testing focuses on ensuring the quality and safety of agricultural products reaching consumers. Codex STAN 193 is a critical component in this effort as it provides harmonized guidelines for the determination and control of mycotoxins across different regions and jurisdictions. By adhering to these standards, laboratories can ensure consistent and reliable testing results that meet international quality requirements.
The standard applies primarily to maize (corn), wheat, barley, rice, oats, soybeans, groundnuts (peanuts), pulses, and other cereal grains. It covers a range of mycotoxins including aflatoxins (Afla), deoxynivalenol (DON or vomitoxin), zearalenone (ZON), fumonisins (FUM), trichothecenes, and others.
The implementation of Codex STAN 193 is crucial for industries dealing with food safety. For example, in the food sector, it ensures that products are free from harmful levels of mycotoxins which could otherwise cause health issues such as liver damage, immunosuppression, and even cancer if consumed over extended periods.
The standard also plays a vital role in agriculture by providing guidelines for reducing contamination risks during crop cultivation. Farmers can use this information to implement practices that minimize fungal growth on their crops, thereby ensuring better quality produce at the time of harvest.
For the food & feed industry, compliance with Codex STAN 193 is essential not only for regulatory purposes but also as a means of maintaining consumer trust. Consumers expect high standards in food safety and are increasingly becoming aware of potential health risks associated with mycotoxin exposure.
Applied Standards
The Codex STAN 193 General Standard for Mycotoxin Contaminants is aligned with several international standards, including the ISO/TS 21957-4, which provides a harmonized approach to mycotoxin analysis in grains and oilseeds. These standards ensure that the testing methodologies used are accurate, reproducible, and consistent across different laboratories.
The standard also aligns with European Union (EU) legislation on food safety, particularly Directive 2002/32/EC which sets maximum levels for mycotoxins in various commodities. By adhering to these regulations, laboratories can ensure that their testing practices meet the stringent requirements set by regulatory bodies.
In addition, Codex STAN 193 supports compliance with World Trade Organization (WTO) agreements on sanitary and phytosanitary measures. This helps facilitate trade between countries while ensuring that exported products comply with local standards.
Scope and Methodology
| Test Method | Description |
|---|---|
| High-Performance Liquid Chromatography (HPLC) | Aflatoxins, fumonisins, trichothecenes, and zearalenone are typically analyzed using HPLC. This method involves extracting the mycotoxins from sample matrices followed by purification steps before injection into the chromatograph. |
| Enzyme-Linked Immunosorbent Assay (ELISA) | For rapid screening of DON, ZON, and other toxins. This method uses antibodies specific to mycotoxins bound to microtiter plates for detection. |
The scope of Codex STAN 193 covers the determination of mycotoxin levels in various foodstuffs and feeds. The methodology involves sample preparation, which includes homogenization, extraction, clean-up, and quantification using either HPLC or ELISA depending on the specific toxin.
The standard specifies acceptable limits for each type of mycotoxin based on risk assessment conducted by Codex Alimentarius Commission (CAC). Laboratories must ensure that their test results fall within these prescribed ranges to comply with the guidelines set forth in this document.
Benefits
