Questions
- What does 21 CFR part 182 cover?
- 21 CFR part 182 is Substances Generally Recognized as Safe. It runs to 85 sections across 7 subparts and sits in subchapter B of chapter I, Food for Human Consumption.
Every section of part 182 is a clause somebody has to produce evidence for at their next audit. Krolda maps supplier documents to the clause they satisfy in FSSC 22000, IFS Food and 21 CFR 117, and routes the corrective action when the evidence is missing.
Early accessRecall records come from the openFDA food enforcement API, published by the U.S. Food and Drug Administration in the public domain. Krolda adds the hazard classification and the clause mapping; neither is an FDA determination. Always check the FDA notice before acting on a recall.
