What's the difference between a Codex standard and a private standard like ISO?
Codex, as an inter-governmental organization, prepares documents to assist governments in their statutory and regulatory work to protect their citizens from health hazards caused by food consumption. Compliance with applicable Codex standards is recommended. ISO, as a non-governmental organization, develops standards that are driven by marketplace needs. As a result, ISO standards describe products, services, process, materials and systems, and conformity assessment. Compliance with ISO standards is mandatory to the extent of fulfilment of certification requirements and is beyond meeting the legal requirements.
Codex and ISO activities are complementary. Codex, as a governmental organization, prepares documents to assist governments in their statutory and regulatory work to protect their citizens from health hazards caused by food consumption. ISO prepares standards in particular on test methods to assist stakeholders along the whole food chain to fulfil both the statutory and regulatory requirements, as well as the requirements of consumers of these products.
