Allergen Labeling in Restaurants: Legal Requirements & Best Practices

A guest sits down and asks: "Does your pasta contain gluten?" Another is severely allergic to peanuts and needs to know which dishes are safe.

These aren't casual questions—they're legal obligations. Since 2014, Swedish law requires restaurants and food businesses to provide accurate allergen information. Get it wrong, and you face inspections, fines, and potential liability if a customer becomes ill.

Here's what you need to know about the 14 major allergens, legal requirements, and practical solutions that won't overwhelm your operation.

Why Allergen Labeling Matters

Food allergies are serious. A person with peanut allergies can have a severe reaction from even tiny amounts. Someone with celiac disease cannot safely consume wheat, barley, or rye.

For these people, accurate allergen information is literally a matter of safety. For you as a restaurant owner, it's both a legal requirement and a matter of customer protection.

The 14 Major Allergens

EU Regulation 1169/2011 lists 14 substances that must be labeled as allergens. If any of these are in your food, you must inform customers:

1. Gluten (wheat, barley, rye, oats, and related grains)
2. Crustaceans (shrimp, crab, lobster)
3. Eggs
4. Fish
5. Peanuts
6. Soybeans and soy products
7. Milk (lactose and casein)
8. Tree nuts (almonds, hazelnuts, walnuts, cashews, pistachios, macadamia, pecans, Brazil nuts)
9. Celery
10. Mustard
11. Sesame seeds
12. Sulfur dioxide and sulfites
13. Lupine
14. Mollusks (snails, mussels, squid)

If any of these appear in a dish—or even in ingredients you use—you must be able to tell customers about it.

What Swedish Law Actually Requires

Since 2014, the law is clear:

• You must be able to inform customers about allergens in your food
• Information must be accessible (menu, signage, or trained staff)
• Information must be accurate and reliable
• You cannot simply say "it might contain allergens"—you must be specific

"This pasta contains gluten and dairy" is compliant. "We can't guarantee anything" is not.

Practical Ways to Provide Allergen Information

1. Allergen-Marked Menu

Mark allergens directly on your menu (printed or digital):

Advantages:

• Customers can read it before ordering
• Professional appearance
• Consistent information for all

Challenges:

• Menus get visually cluttered
• Time-consuming to update when recipes change
• Easy to miss updating certain items

2. Allergen Table or Chart

Create a separate table where customers look up allergens for each dish:

Carbonara — gluten, eggs, dairy
Caesar Salad — eggs, fish
Pad Thai — peanuts, fish

Advantages:

• Cleaner menu
• Easier to update
• Easy for customers to compare

Challenges:

• Customers must actively look it up
• Some people forget to ask

3. Staff as Information Source

Train your staff to answer allergen questions:

Advantages:

• Flexible—you can explain modifications
• Personal touch

Challenges:

• Requires well-trained staff
• Higher risk of mistakes
• Slower for customers

4. Digital Menu System (Recommended)

Modern digital menu systems (often integrated with your POS) can display allergen information instantly. Customers use their phone or a restaurant tablet to view the menu and can filter by allergens or see detailed information with one click.

Advantages:

• Always current—updates instantly
• Customers filter by their allergies
• Easy to update when recipes change
• Professional appearance
• Can show real-time availability changes

Challenges:

• Requires technology
• Some older guests may prefer paper

Common Mistakes Restaurants Make

Mistake 1: Trusting your supplier entirely

Your supplier says the pasta is gluten-free. But the pasta was made in a facility that also processes wheat. For someone with severe celiac disease, that's not safe.

Verify information independently and keep documentation.

Mistake 2: Relying only on staff memory

A server says "Yes, it's gluten-free" because she thinks it is. But the sauce contains flour. Staff memory is unreliable.

Keep a central, documented allergen database that everyone consults.

Mistake 3: Failing to update when recipes change

You switch tomato sauce suppliers. The new sauce contains dairy; the old one didn't. You forget to update the menu. A customer gets sick.

Create a process: whenever an ingredient changes, update your allergen database immediately.

Mistake 4: Over-disclaiming

Some restaurants say: "We can't guarantee anything because we share a kitchen."

That's overly cautious and poor customer service. Instead: "This dish contains these allergens. If you're allergic to something else, it's safe to eat."

Legal Consequences of Violations

Your municipality's food safety inspectors can:

• Issue warnings
• Mandate corrections
• Issue fines
• Shut down your operation in severe cases
• Create liability if a customer becomes ill

Allergen information is taken seriously by regulators.

Your Practical Checklist

Week 1:

• Review all recipes and identify all 14 allergens in each dish
• Document the source of each ingredient (supplier, packaging, label)
• Create an allergen database

Week 2:

• Update your menu with allergen information
• Train staff on allergen questions and proper responses
• Create an internal checklist for new ingredient purchases

Week 3:

• Test your system—have a staff member find allergen info on the menu
• Ask a customer to test it—can they quickly find allergen info?

Ongoing:

• Update your database immediately when ingredients change
• Train new staff on allergen procedures
• Review all recipes annually

Digital Solutions

Modern POS systems and digital menu platforms can automate this:

• Store allergen information centrally
• Update instantly across all platforms
• Provide customer-facing filters
• Generate compliance reports
• Flag cross-contamination risks

This eliminates much of the manual work and reduces mistakes.

Special Considerations

Cross-Contamination Risks

If your kitchen handles multiple allergens, there's always some risk of cross-contamination (tiny amounts of allergen from one dish mixing into another). You must inform customers about this risk.

"This dish is made in a kitchen that also handles peanuts—we cannot guarantee zero peanut residue" is honest and legally compliant.

Unlisted Ingredients

If you don't know what's in something, you cannot serve it. You must know every ingredient in every dish.

Changing Suppliers

When you switch to a new supplier, immediately verify allergen information in writing. Update your database before serving.

Building a Culture of Safety

Allergen compliance isn't just a legal box to check—it's about genuine customer safety. When your team treats allergen information seriously, you:

• Protect vulnerable customers
• Build trust and reputation
• Avoid legal problems
• Create peace of mind for yourself and your staff

Frequently Asked Questions

Must all 14 allergens be labeled?

Yes, all 14 from EU Regulation 1169/2011 must be labeled if present in your food.

Does "may contain traces of" count as allergen labeling?

Yes. If there's risk of cross-contamination, customers must be informed.

What if a customer claims an allergy that isn't medically verified?

You cannot judge. Treat all allergen information as serious. It's not your role to be skeptical.

Can we serve allergen-containing food without labeling?

No. The law requires you to inform customers. Serving without disclosure is a violation.

How reliable is supplier allergen information?

Partially reliable, but verify it. Request written confirmation from suppliers, and keep documentation. Don't assume.

What if we're unsure about an ingredient?

Don't serve it. You must know what goes into your food. Contact your supplier and get clarity.
