Food allergen labeling: what to include on labels (and menus)

Food allergen labelling helps customers avoid allergens and helps food businesses stay compliant. A complete allergen declaration usually combines three things:

If you’re building labels for packaged foods, menus, or PPDS items, MenuSano can help you move from a quick check to compliance-ready outputs using our allergen labelling software and allergen compliance workflows.

“Contains” & “may contain” statements, and precautionary allergen labelling

A “contains” statement is used to clearly declare major allergens present in the product (for example: Contains: Milk, Eggs, Wheat). A “may contain statement” (also called an allergen advisory statement) is different: it’s used for potential cross-contact risk, such as:

These are all forms of precautionary allergen labelling. They should be used carefully and consistently; overusing precautionary allergen labelling can reduce trust, but underusing it can increase risk.

Allergen labeling requirements by country (US, Canada, UK)

US allergen labeling (Top 9 allergens)

In the United States, FDA allergen labelling rules require clear identification of major food allergens on packaged foods. Many businesses follow FALCPA allergen labelling principles and current FDA guidance for the top 9 allergens (including sesame allergen labelling FDA updates).

If you’re trying to confirm allergen labelling requirements in the US or looking for allergen labelling examples, the safest approach is to standardize your ingredient list + “Contains” statement format across every SKU and every recipe revision.

Canada allergen labelling

In Canada, CFIA allergen labelling and Health Canada allergen labelling guidance focus on a clear declaration of priority allergens in Canada. Many products also need bilingual considerations, including allergen declaration bilingual Canada, where required.

If you’re handling cross-contact risk, precautionary allergen labelling Canada (including “may contain labelling Canada”) should be applied consistently and backed by real process controls.

UK allergen labelling (Natasha’s Law, PPDS, 14 allergens)

UK allergen labelling requirements apply across packaged foods and food sold direct to consumers. Natasha’s Law allergen labelling (PPDS) requires clearer allergen information for PPDS allergen labelling, and many businesses standardize around the UK 14 allergens labelling list (aligned with EU/FIC concepts like EU allergen labelling 14 allergens and food information regulations allergens (FIC)).

If you run a bakery, café, or takeaway, your process often needs both:

Allergen information for restaurants: menus, allergen matrix, and customer guides

If you serve food (restaurants, catering, bakeries, meal prep), you’ll often need allergen info in more than one format:

allergen menu labeling (menu icons, disclosures, or printed statements)
allergen chart for restaurant (front-of-house friendly)
allergen matrix template (kitchen + compliance team friendly)
allergen guide for customers (simple, readable, consistent)

This is where software helps: instead of maintaining spreadsheets manually, you can generate consistent outputs from a single ingredient + recipe source of truth.

The Proof is in the Pudding

Simple Interface, Good Feature Set, Excellent Price. Very easy to use, and comes with a short tutorial.

Trevor Nawalkowski - Trevor's Pizza

Sending our recipes to a nutritionist, or out to a lab and having to wait three weeks for results is timely. Instead we use MenuSano, a web-based nutritional calculator. It really has made this journey easier for me.

Thao Nguyen - BonBon Collections

MenuSano delivered on all fronts; nutrition labeling, ingredient sourcing, and all kinds of applications we hadn't even thought of. Sooo intuitive and easy to use, not sure where we would be without them!

Eric Krautheim - Township 27

I was immediately impressed by their expertise and openness to feedback.

Caroline - Boundary Labels

MenuSano allows us to calculate our recipes with accuracy and instantly, it checks potential variations in the recipe.

Kevin Harbison - Bridgehead

The one thing we were surprised to find out is how much sodium our recipes contain. We thought we used minimal salt but Menusano helped us discover that some of our recipes contained a surprising amount, which made us change some of our recipes.

Grace Willows - Windmill Bakery

The best software by far for food companies. This software saved me. I had a deadline and the person I usually get to do my nutritional was not available. Thanks to this software, we will be doing it all ourselves from now on.

Jessica Otano - Jessica's Gourmet

MenuSano was able to adapt, use creativity, grow, and even assist in projects to ensure our company met our client requests.
