Overview
RDC Nº 722 is Brazil’s framework resolution for maximum tolerated limits of contaminants in foods. The PDF in raw/regulatory contains the legal framework text; it points to Instrução Normativa IN Nº 160, de 1º de julho de 2022 for the contaminant-specific LMT tables. This page therefore records the regulatory framework and does not invent numeric food-by-contaminant limits from a companion document that is not present in the folder.
Key numbers
| Provision | Extracted source fact |
|---|---|
| Art. 1 | The resolution covers maximum tolerated limits (LMT) for contaminants in foods, general principles for establishing them, and methods of analysis for conformity assessment. |
| Art. 2 | The resolution applies to the whole food production chain. |
| Art. 3 | LMT means the maximum concentration of the contaminant legally accepted in the food. |
| Art. 6 | The contaminant LMTs are defined in Instrução Normativa IN Nº 160, de 1º de julho de 2022. |
| Art. 6, sole paragraph | LMTs apply to the edible part of foods and to the product as exposed for sale, except where IN Nº 160 specifies otherwise. |
| Art. 7 | For dehydrated, diluted, transformed, or compound foods made from listed ingredients, the LMT assessment considers ingredient proportions, concentration changes from processing, and analytical quantification limits. |
| Art. 10 | Methods used to verify LMT compliance must meet performance criteria in the current Codex Alimentarius procedural manual. |
| Art. 10, §1-2 | For inorganic arsenic LMT verification, total arsenic methods may be used first; if results exceed the corresponding LMT, inorganic arsenic testing must be performed. |
| Art. 13 | RDC 722 entered into force on 2022-07-01. |
The resolution incorporates MERCOSUR GMC Resolutions 103/1994, 25/2002, 12/2011, and 18/2021 into Brazil’s national framework.
Methods (brief)
This is a legal framework source. It is not a laboratory study and does not report sample measurements. The source’s method-relevant content is the conformity-assessment rule in Art. 10 and the iAs/tAs screening rule in Art. 10, §1-2.
Implications
Certification: The source identifies Brazil’s regulatory mechanism and basis rules but not standalone HMTc thresholds.
Courses: The source is useful for explaining how Brazil separates framework rules in RDC 722 from numeric LMT tables in IN 160.
App: The source can support Brazil jurisdiction labels only after the IN 160 numeric limits are ingested.
Microbiome: No direct microbiome endpoint.
