Trace major food allergens from formula to final label

Why this review needs product evidence

A checklist based only on the finished ingredient names can miss allergens in flavors, spice blends, coatings, processing aids, or supplier substitutions. Sesame is included among the U.S. major allergens. Cross-contact controls and advisory statements are separate from the mandatory source declaration and need their own risk assessment.

Recommended review sequence

1. Create an allergen matrix for every direct ingredient, sub-ingredient, rework stream, and processing aid.
2. Verify supplier allergen statements against the exact item and revision purchased.
3. Choose a compliant declaration method and preserve the food-source names required for major allergens.
4. Check the ingredient list and any Contains statement for agreement, adjacency, type treatment, and completeness.
5. Assess shared equipment and cross-contact controls without using advisory language as a substitute for preventive controls.
6. Repeat the review after any formula, supplier, facility, or process change.

Evidence to keep with the released label

Retain supplier specifications, allergen questionnaires, certificates where relevant, the internal allergen matrix, sanitation and changeover records, label reconciliation, and approval history. The released artwork should be connected to the same source documents used for the manufacturing lot. Conflicting supplier records should block automatic acceptance.

What the pre-check cannot prove

Frequent problems include omitting an allergen contained in a compound ingredient, naming a tree nut too generically, failing to update for sesame, and assuming “may contain” cures an incomplete mandatory declaration. A visible Contains line proves only that text was detected; it does not establish that the underlying allergen inventory is complete.

Automatic extraction is accepted only when required text is present in two OCR passes, image quality and layout evidence meet the configured threshold, and the submitted product facts agree with the recognized text. Otherwise the upload is rejected for clearer, complete panels. This does not establish population-wide OCR accuracy or regulatory compliance.
