Every section of part 509 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.
