Under current FDA law and guidance, you must declare nine major allergens (milk, egg, fish, Crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame) on FDA-regulated packaged foods, either in the ingredient list or in a “Contains” statement placed right next to it. FDA’s Edition 5 guidance, issued in January 2025, changed how milk and eggs get interpreted and updated the tree nut list. If your label templates predate that update, they may already be out of step.
TL;DR:
- Manufacturers must declare all nine major FDA allergens, including sesame since 2023, with no exceptions for trace amounts or processing aids.
- The 2025 Edition 5 update requires explicit species and type declarations for fish, shellfish, and nuts, and specific mention of milk from goats or sheep.
- The “Contains” statement must always start with that word, include all allergens present, and be placed immediately after or near the ingredient list in legible type.
- Shared equipment and rework procedures need strict controls, such as dedicated lines, validated sanitation, and sequencing to prevent cross-contact and accidental contamination.
- Imported products must have their allergen information verified against FDA standards, regardless of foreign labels, and revised if necessary before relabeling for US compliance.

What Are the FDA Allergen Labeling Rules Under FALCPA and FASTER?
The legal foundation here is short but strict. Section 201(qq) of the Food, Drug, and Cosmetic Act names the major food allergens, and the FASTER Act added sesame to that list starting in 2023. That gives you nine allergens you’re legally required to flag, no exceptions for “just a trace” or “processing aid only.”
- Milk
- Egg
- Fish
- Crustacean shellfish
- Tree nuts
- Peanuts
- Wheat
- Soybeans
- Sesame
FDA’s Edition 5 update, released in January 2025, isn’t cosmetic. It expands how “milk” and “eggs” get interpreted on labels, and it revises the tree nut list to close gaps manufacturers had been relying on for years.
Species and type rules matter more than most labeling teams realize. Fish must be declared by species (think “cod” or “tilapia,” not just “fish”), Crustacean shellfish by type (shrimp, crab, lobster), and tree nuts the same way (almond, walnut, cashew). A vague “shellfish” or “nut” callout doesn’t cut it anymore, and under Edition 5, milk from goats or sheep needs its own explicit declaration since it’s no longer safely covered by an implied “milk” reference to cow’s milk.
Where and How Do You Declare Allergens on a Label?
FDA gives you two legitimate paths under section 403(w)(1), and the Food Labeling Guide spells out both. You can name the allergen source in a parenthetical right after the ingredient itself (say, “whey (milk)”), or you can put every major allergen in the food into a single “Contains” statement positioned immediately after or adjacent to the ingredient list.
A few formatting rules aren’t optional. The statement must start with the word “Contains.” Its type size can’t be smaller than the ingredient list’s type, and FDA guidance recommends keeping it in the same font family so nothing reads as an afterthought. Most importantly, the “Contains” statement has to list every major allergen present in the product, not just the one you happened to think of first.
Common mistakes we see across the industry:
- Using vague ingredient names (“natural flavor,” “spices”) without tracing back to the allergenic source
- Listing some allergens in the ingredient list but forgetting to repeat them all in the “Contains” line
- Assuming a supplier’s spec sheet covers your legal disclosure obligation
- Treating tree nut or fish species generically instead of naming the specific type
Pro Tip: Run your “Contains” statement side by side with your full ingredient list every time you tweak a recipe. It takes two minutes and catches the single most common labeling error we see in confectionery and snack production.
Which Products and Packaging Does FDA Allergen Labeling Cover?
The scope question trips up more manufacturers than the allergen list itself. FDA allergen labeling requirements apply to FDA-regulated foods, which includes packaged snacks, candy, chocolate, and dietary supplements. USDA regulates meat, poultry, and most egg products, along with catfish, so those fall outside FDA’s allergen labeling rules and follow separate USDA labeling requirements instead.
A few scope details catch people off guard:
- Bulk containers still require allergen declarations. A private label agreement or a purchase order promising downstream disclosure doesn’t exempt the manufacturer from labeling the container itself.
- Flavors, colors, and incidental additives are not exempt from allergen disclosure. If a flavor system contains milk protein, FDA requires it declared just like any other ingredient, regardless of how small the amount or how “incidental” it seems.
- Dietary supplements follow the same major allergen declaration rules as conventional foods, so gummy vitamins and supplement powders aren’t a loophole.
How Do CGMP and Preventive Controls Prevent Allergen Cross-Contact?
Most allergen violations FDA documents aren’t deliberate mislabeling. They come from manufacturing practices that let an allergen sneak into a product that isn’t supposed to contain it. That’s where 21 CFR Part 117, covering current good manufacturing practices and preventive controls, comes into play. Investigators look at shared equipment, rework handling, and sanitation validation as the usual suspects.
Practical controls worth building into your operation:
- Dedicate lines or equipment to allergen-containing products wherever your production volume allows it.
- Validate your sanitation procedures with actual swab testing, not just a visual “looks clean” check.
- Set firm rework rules: only add rework back into a batch that shares the exact same allergen profile.
- Schedule allergen-free runs before allergen-containing runs whenever a shared line is unavoidable.
- Verify allergen declarations from every ingredient supplier before that ingredient enters your facility, especially compound ingredients.
Pro Tip: If you run shared equipment across multiple SKUs, a strict “allergen-free to allergen-heavy” production sequence beats almost any cleaning validation shortcut. Sequencing is often cheaper and more reliable than an extra deep clean.
Get this wrong, and you’re not just risking a labeling problem. Cross-contact caused by insanitary conditions can render a product adulterated under section 402(a)(4), a much more serious enforcement category than a simple missing “Contains” line.
What Should a Compliance Checklist Cover Right Now?
A structured audit beats scrambling after an inspector flags something. Break it into three workstreams:
Label review:
- Inventory every current label template across your product lines.
- Audit each ingredient declaration against the actual formulation, not the original recipe card from three years ago.
- Update every “Contains” statement to reflect Edition 5’s expanded milk and egg interpretations.
Supply chain verification:
- Require signed allergen declarations from every ingredient supplier, updated annually at minimum.
- Review multi-ingredient inputs like flavor blends and coatings for hidden allergen sources.
- Consider periodic spot testing or certificates of analysis for high-risk suppliers.
Operations and recordkeeping:
- Update SOPs for cleaning, rework, and production scheduling to reflect the controls above.
- Keep inspection-ready records showing when each control was performed and by whom.
- Set a firm timeline (most manufacturers target 60 to 90 days) for rolling updated label artwork across all SKUs.
Space-man’s own allergen labeling requirements guide walks through this audit process in more detail if you want a longer-form reference to hand to your labeling team.
How Do You Petition FDA for an Allergen Labeling Exemption?
Section 403(w)(6) and (7) give you two routes if you believe an ingredient doesn’t warrant a major allergen declaration. The petition route requires submitting scientific evidence for FDA review, with no fixed timeline since it depends on the complexity of the science involved. The notification route moves faster: it runs on a 90-day clock, after which you may introduce the product unless FDA objects.
Either way, FDA expects real evidence, not assertions:
- Validated analytical methods showing the allergenic protein isn’t detectable
- Data demonstrating the manufacturing process removes or denatures the allergenic protein
- Any relevant premarket approvals tied to the ingredient in question
Approved notifications get posted publicly, so you can check precedent before filing your own.
What Triggers FDA Enforcement for Allergen Violations?
FDA’s enforcement approach is risk-based, meaning inspectors and compliance staff prioritize cases with the highest potential harm to allergic consumers rather than treating every infraction identically. That said, two categories carry very different weight. Misbranding covers an undeclared allergen sitting right there on the label, an ingredient list gap, or a “Contains” statement that’s missing something. Adulteration covers cross-contact caused by insanitary conditions, which CPG Sec 555.250 treats as a more serious category tied to section 402(a)(4).
Common violations investigators document:
- Missing allergens in the ingredient list entirely
- Incomplete “Contains” statements that leave out one or more allergens actually present
- Inadequate GMP records showing no real cross-contact prevention plan
If you get cited, move fast: draft a corrective action plan, relabel or apply corrective stickers to existing stock, fix the supplier issue at its source, and set a realistic timeline for permanent label updates.
What Font Size and Format Rules Apply to Allergen Statements?
FDA doesn’t hand manufacturers a strict point-size number for allergen labeling the way it does for the Nutrition Facts panel. Instead, the rule is relative: your “Contains” statement type size can’t be smaller than the type used in your ingredient list, and FDA’s Food Labeling Guide recommends keeping both in the same font family so the allergen statement doesn’t read like an afterthought squeezed into a corner.
Placement matters as much as size. The “Contains” statement needs to sit immediately after or adjacent to the ingredient list, not buried near the nutrition panel or tucked onto a side panel disconnected from the ingredients. If you’re using the parenthetical method instead (naming the source right inside the ingredient list, like “casein (milk)”), that parenthetical needs to be legible at the same size as the surrounding ingredient text, not shrunk down to save label space.
A few practical formatting notes that trip up smaller manufacturers:
- Bold or all caps for “Contains” isn’t required, but many labeling teams use it anyway for legibility. Just don’t let styling choices shrink the actual type size below the ingredient list’s.
- If your package is small (think single-serve candy pouches), FDA still expects full allergen disclosure. Tiny packaging isn’t grounds for omitting the statement, though it may affect which type-size exemptions apply elsewhere on the label.
- Color contrast matters practically even where it isn’t spelled out as a numeric requirement. A “Contains” statement printed in white on a pale background technically meets a type-size rule but fails the actual purpose of alerting an allergic consumer.
The safest approach: treat your allergen statement as a legibility problem first and a legal minimum second. FDA’s compliance reviewers and your own customers are looking at the same line of text.
How Should Blended Ingredients and Processing Aids Be Labeled?
Compound ingredients cause more labeling headaches than straightforward single-source ones. A “natural flavor,” a seasoning blend, a chocolate coating, or a starch system can each carry an allergen buried three suppliers deep, and FDA holds you responsible for tracing it regardless of how many hands the ingredient passed through before it reached your facility.
The rule itself is simple: if a blended ingredient contains a major allergen anywhere in its composition, that allergen has to appear on your finished product’s label, either in the ingredient list parenthetical or the “Contains” statement. What’s not simple is getting the documentation. You need your supplier to disclose the full allergen profile of every compound ingredient they sell you, not just a general “may contain” disclaimer that shifts liability without giving you the specifics you need to label correctly.
Processing aids deserve particular attention because they sometimes disappear from ingredient lists entirely if they’re not present in the final product at a functional or technically significant level. That exemption does not extend to allergens. If a processing aid used earlier in manufacturing (a mold release agent containing soy lecithin, for example) leaves any allergenic protein residue, disclosure is still required. Treating a processing aid as automatically exempt because it’s “not really an ingredient” is one of the more common misunderstandings we see among newer confectionery manufacturers.
Practical fix: build a standing requirement into your supplier contracts that any compound ingredient or processing aid comes with a full allergen breakdown, updated whenever the supplier changes their own formulation. Natural colorants are a good example of where this gets tricky, since sourcing shifts (say, from one plant extract to another) can quietly introduce a new allergen without anyone flagging it. Wild Foodz’s guide to natural red colorant sourcing is a useful reference if you’re working with plant-based colorants and want to understand supplier disclosure practices in that category specifically.
What Should Importers Check Before Labeling FDA-Regulated Foods?
Imported products face the same nine-allergen standard as domestically manufactured goods, but the paper trail gets harder to verify. A foreign supplier’s label, written to satisfy that country’s own regulations, often uses different allergen terminology, different threshold rules, or a different required allergen list entirely. The European Union, for example, requires disclosure of allergens FDA doesn’t currently mandate the same way, and vice versa.
Before you relabel or repackage an imported product for the US market, verify the original formulation against the FDA’s nine-allergen list directly. Don’t rely on the foreign label’s own allergen callouts as a substitute, since a product compliant with another country’s rules can still be missing something FDA requires. This is especially common with sesame, since some markets didn’t require sesame disclosure before FASTER Act enforcement began in the US.
A few best practices for imported goods specifically:
- Request the original ingredient and allergen documentation in the source language plus a certified translation, not just a summary
- Re-verify allergen sourcing for any compound ingredient, since supplier substitutions happen more often across international supply chains
- Build in extra lead time for relabeling imported stock, since customs holds and import compliance reviews add unpredictable delays
- Confirm whether the product falls under FDA jurisdiction at all. Certain imported meat, poultry, or egg products fall under USDA rather than FDA
If you’re private-labeling or repackaging imported product domestically, the responsibility for accurate allergen labeling sits with whoever puts the final label on the package, not the original overseas manufacturer.
A Confectionery Manufacturer’s Take on Allergen Labeling Compliance
The manufacturers who struggle most with allergen compliance aren’t the ones ignoring the rules. They’re the ones running small-batch or private-label production where formulations shift often but label artwork doesn’t keep pace. Version control matters more in that environment than almost anywhere else in food manufacturing.
Our practical advice: treat every recipe change as a labeling event, not just a production event. Small-batch rework rules need to be explicit and written down, and supplier attestations should be collected before a new ingredient ever hits your line, not after. Space-man’s guide on food safety in candy manufacturing covers the operational side of this in more depth, and the federal and state labeling checklist is worth running alongside your next label audit.

Need Help Turning Compliant Labels Into Finished Product?
Space-man handles private label and co-packing production in Canada with allergen controls built into the workflow, not bolted on after the fact. If you’re a manufacturer trying to translate everything above into an actual production run, that’s the gap our private label, co-packing, and packaging services exist to close: dry food co-packing, pouch packaging, commercial freeze drying, and confectionery production handled under one roof, with label updates and allergen documentation reviewed before anything ships.
If you’re launching a private-label candy, chocolate, or freeze-dried treat line and need labels that hold up to FDA scrutiny from day one, request a consultation through the services page above. If you’re a retail buyer looking for finished, allergen-labeled product instead of a manufacturing partnership, browse the freeze-dried candy and treats collection to see current packaging examples. Either way, the next step is the same: get your formulation and label draft in front of a team that packages allergen compliance into the production schedule itself, not just the final proofread.

FAQ
What Are the Nine Major FDA Food Allergens?
The nine major allergens are milk, egg, fish, Crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. Sesame was the most recent addition, required under the FASTER Act starting in 2023.
What Allergens Need to Be Labeled on Food Packaging?
All nine major allergens above must be declared on FDA-regulated food packaging, either through a parenthetical in the ingredient list or a “Contains” statement placed next to it. This applies regardless of how small the amount is, including allergens introduced through flavors, colors, or other incidental additives.
What Are the New Food Labeling Requirements Coming in 2026?
The most significant recent change is FDA’s Edition 5 guidance, issued in January 2025, which expanded interpretations of “milk” and “eggs” and revised the tree nut list. There’s no separate major overhaul specific to 2026, but manufacturers who haven’t updated templates since Edition 5 should treat that as the priority.
What Are the FDA Requirements for General Food Labeling?
Beyond allergen disclosure, FDA requires an accurate ingredient list in descending order by weight, a Nutrition Facts panel, and net quantity statements, all governed under 21 CFR Part 101. Allergen labeling under section 403(w) sits alongside these as a distinct, mandatory requirement rather than an optional add-on.
Does Space-man Handle Allergen-Compliant Private Label Packaging?
Yes. Space-man’s private label and co-packing services are built around Canadian food safety and labeling compliance, covering confectionery, chocolate, and freeze-dried treat production for manufacturers who need packaging that reflects current allergen declaration rules.
