Allergen Statement Supplements

Allergen statement & cross-contact control is the dual brand-side / facility-side regime that prevents undeclared-allergen recalls. Brands are responsible for accurate label declaration of every major allergen present in the product (either via 'Contains:' statement or parenthetical naming in the ingredient list). Facilities are responsible for cross-contact controls — preventing unintended allergen carryover from one product to another via shared equipment, shared air-handling, shared utensils, or shared personnel.

FALCPA permits two declaration methods (brand picks one — both is permitted but not required):

• 'Contains:' statement — immediately after the ingredient list. Example: 'Contains: Milk, Soy.' All major allergens in the product must be listed; the order does not matter.
• Parenthetical declaration — major allergen named in plain English in the ingredient list itself. Example: 'lecithin (soy)' or 'casein (milk)'. Common name (e.g. 'milk') must appear, not the technical name alone (e.g. 'casein' without parenthetical is non-compliant).

Tree nuts and fish/shellfish require the specific type (e.g. 'almonds', not just 'tree nuts'; 'shrimp', not just 'shellfish'). Sesame follows the same rules as the original eight.

Cross-contact prevention sits in 21 CFR 117 Subpart C (Hazard Analysis and Risk-Based Preventive Controls, allergen preventive controls). Supplement facilities under Part 111 cross-reference these requirements via §111.55 (sanitation) and §111.80 (component receipt / quarantine). The controls divide into:

• Engineering / physical — dedicated equipment for high-risk allergens (e.g. dedicated peanut line), physical segregation in storage (allergens below non-allergens, never above), separate utensils colour-coded by allergen status.
• Procedural — line scheduling (allergen-containing products run at end of shift, then full sanitation; non-allergen products start fresh shift), changeover SOPs with documented sanitation verification, allergen-status colour-coded labels on intermediates and bulk containers.
• Sanitation validation — swab + ELISA testing for residual allergen protein after changeover sanitation; documented LOD for each allergen ELISA; validated reduction to below threshold (typically 5 ppm for high-risk allergens).
• Supplier qualification — incoming-material allergen verification; supplier-disclosure of facility cross-contact risk (e.g. ingredient produced in shared facility with peanuts must be flagged).
• Training — all personnel trained on allergen identification, cross-contact prevention, changeover SOP, sanitation verification. Annual refresher with competency check.

Undeclared allergens are a leading cause of food and supplement recalls. Common root causes:

• Label error — wrong label applied to product (most common; ~40% of undeclared-allergen recalls). Prevented by line-clearance and label reconciliation (Part 111 Subpart H).
• Formulation change without label update — ingredient swap that introduces a new allergen, label not updated. Prevented by change-control workflow that triggers label re-review.
• Supplier substitution — supplier ships an alternate ingredient containing an allergen not in the original spec. Prevented by incoming-material identity verification (§111.75) + supplier qualification.
• Cross-contact carryover — shared equipment runs an allergen-containing product followed by a non-declared product without adequate sanitation. Prevented by changeover SOP + swab verification.
• Sesame-specific — post-FASTER Act 2023, sesame-undeclared recalls spiked as facilities and brands worked through ingredient-level discovery (e.g. 'spices' or 'natural flavour' that included sesame derivatives).

• Component allergen profile: per-component flags for all 9 major allergens + 'shared-facility' precautionary risk.
• BOM allergen roll-up: finished-SKU allergen profile automatically computed from BOM; surfaces every allergen present (any component contributing).
• Supplement Facts auto-generation: 'Contains:' statement generated from BOM roll-up; brand reviewer signs off as last gate before MMR release.
• Change-control hook: any BOM change that adds or removes an allergen triggers automatic label re-review workflow + sticker re-approval.
• Line scheduling: WO scheduler flags when next WO has different allergen profile from current; requires changeover + sanitation evidence before release.
• Changeover SOP linkage: per-allergen changeover SOP attached to WO; operator must complete + sign all steps.
• Swab + ELISA verification: post-changeover allergen swab results entered + attached to changeover record; below-LOD = pass; above-LOD = re-clean + re-swab.
• Label reconciliation: incoming label count + applied count + reject + remaining count reconciled per Part 111 Subpart H; any allergen-statement discrepancy locks WO release.
• Recall pre-flight: if undeclared-allergen exposure is detected, V5 generates downstream-lot recall scope (forward genealogy) + customer notification list + FDA Reportable Food Registry submission prep.
• FASTER Act sesame audit: one-click report listing every component flagged as sesame-source (including 'natural flavour' / 'spice' inheritances) to support post-Act discovery work.
