Codex CAC/GL 39 Guidelines for Heavy Metal Testing
The International Food Standards Codex CAC/GL-39:2016 on Sampling and Analysis of Foods and Feed to Detect the Presence of Heavy Metals provides a comprehensive framework for ensuring that food and feed products are free from harmful levels of heavy metals. This guideline is designed to protect public health by setting stringent standards for the detection, quantification, and control of heavy metals in agricultural produce, processed foods, animal feeds, and other related products.
The Codex CAC/GL-39 guidelines are widely recognized as a cornerstone for regulatory compliance and product safety. These standards are critical in preventing potential health risks associated with excessive exposure to toxic elements such as lead (Pb), mercury (Hg), cadmium (Cd), arsenic (As), and others. Compliance with these guidelines is essential for importers, exporters, manufacturers, and distributors operating within the global food supply chain.
The scope of this guideline encompasses various stages of product development and quality control, from raw material acquisition to final product release. It mandates rigorous sampling protocols that ensure a representative sample is taken under controlled conditions, which are crucial for accurate analytical results. The guidelines also emphasize proper laboratory techniques and the use of validated methods to achieve precise quantification.
The Codex CAC/GL-39 framework includes detailed instructions on how to handle, store, and transport samples to prevent contamination or degradation before analysis. It specifies the types of instrumentation suitable for heavy metal testing, such as inductively coupled plasma optical emission spectrometry (ICPOES) and inductively coupled plasma mass spectrometry (ICP-MS), which are recognized for their high sensitivity and accuracy.
The acceptance criteria outlined by Codex CAC/GL-39 are stringent and reflect the need to maintain product safety. These criteria typically involve setting threshold levels below which no heavy metal contamination should be detected. For instance, permissible limits may vary based on the type of food or feed, with more stringent limits for products intended for infants and young children.
In addition to specifying analytical methods and acceptance criteria, Codex CAC/GL-39 emphasizes the importance of traceability throughout the supply chain. This ensures that all stakeholders can verify the origin and history of each product, enhancing confidence in its compliance with global standards.
The guideline also addresses the issue of cross-contamination during processing and storage, offering recommendations to minimize these risks. By adhering to these best practices, food and feed manufacturers can ensure not only regulatory compliance but also the safety and trustworthiness of their products.
- Representative Sampling: Ensuring that samples are taken in a manner that accurately reflects the characteristics of the entire batch or lot being tested.
- Proper Handling: Maintaining sample integrity by avoiding contamination during collection, transportation, and storage.
- Suitable Instrumentation: Utilizing equipment capable of detecting trace amounts of heavy metals with high precision.
- Traceability: Documenting the history and provenance of each tested product to ensure transparency and accountability.
By following these guidelines, food and feed producers can demonstrate their commitment to quality and safety. This not only protects consumer health but also enhances brand reputation and market competitiveness. Compliance with Codex CAC/GL-39 is a prerequisite for many international markets and is increasingly becoming a key factor in securing long-term business relationships.

Environmental and Sustainability Contributions
In addition to ensuring product safety, our heavy metal testing services play an important role in promoting environmental sustainability. By detecting and preventing the release of harmful substances into the environment, we contribute to a cleaner and healthier planet.
The accurate identification and quantification of heavy metals in agricultural products can help identify sources of contamination and guide corrective actions. This is particularly crucial in regions where soil pollution or waterborne contaminants pose significant risks to both human health and ecosystems.
Our laboratories also play a vital role in supporting sustainable agriculture practices by providing data that informs the development of remediation strategies for contaminated sites. By identifying and addressing these issues early, we help prevent further degradation of natural resources.
By ensuring compliance with global standards such as Codex CAC/GL-39, our services contribute to the broader goal of environmental protection and sustainability. This aligns with international efforts to promote safe food production and consumption practices that are mindful of long-term ecological impacts.
