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 allergen is consistently the single largest recall category for dietary supplements (and for food generally). Root causes from FDA recall data:

• 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.
