Food service establishments face 73% more allergen-related violations than packaged food manufacturers, primarily due to misunderstanding disclosure requirements. Restaurants must provide allergen information upon request, while packaged products display permanent labels. This creates distinct compliance challenges for food service operators.
The fundamental difference
For packaged products: all 14 EU allergens must always be visible on the label. For food service: allergens must be provided upon request and communicated correctly to the guest.
💡 Example:
A packaged pasta salad in the supermarket:
- Label shows: "Contains gluten, eggs, celery"
- Customer sees this before purchase
- No further questions possible
The same pasta salad in your restaurant:
- Listed on menu: "Pasta salad"
- Customer asks: "Does it contain allergens?"
- You must answer correctly: "Yes, gluten, eggs, and celery"
What food service operators MUST be able to do
As a food service operator, you're required to provide the following information upon customer request:
- Which of the 14 EU allergens are in the dish
- In which ingredients these allergens are found
- Risk of cross-contamination (for example: "Prepared in a kitchen where nuts are processed")
⚠️ Note:
You don't need to proactively list all allergens on the menu, but you must have them ready if a customer asks. Being unable to provide an answer violates regulations.
The 14 mandatory allergens for food service
These match packaged product requirements, but you register them differently:
- Gluten (wheat, rye, barley, oats, spelt, kamut)
- Crustaceans (shrimp, crab, langoustines)
- Eggs (also in mayonnaise, pasta, baked goods)
- Fish (also in Worcestershire sauce, anchovies in dressing)
- Peanuts (also peanut oil, satay sauce)
- Soy (also soy sauce, tofu)
- Milk (also lactose, butter, cheese)
- Tree nuts (8 types: almond, hazelnut, walnut, cashew, pecan, Brazil nut, pistachio, macadamia)
- Celery (also celery salt, bouillon cubes)
- Mustard (also mustard seed in spices)
- Sesame (also sesame oil, tahini)
- Sulfites (also in wine, dried fruit)
- Lupin (lupin flour in bread)
- Mollusks (mussels, squid, snails)
Practical differences in registration
💡 Example:
Caesar salad in your restaurant:
A packaged product would label:
- "Contains: fish, eggs, milk, gluten"
Your registration must be more specific:
- Anchovies in dressing = fish
- Parmesan = milk
- Croutons = gluten (wheat)
- Mayonnaise in dressing = eggs
Cross-contamination: the big difference
Packaged products use standard text like "May contain traces of nuts". In food service, you need to be more specific about your own kitchen:
- Same cutting board for bread and vegetables = possible gluten cross-contamination
- Fryer for fish and fries = possible fish cross-contamination in fries
- Same tongs for cheese and vegan dishes = possible milk cross-contamination
⚠️ Note:
A customer with a serious allergy gets more value from "We prepare this on the same grill as fish" than from "May contain traces of fish". Be specific about your kitchen processes.
Digital registration vs. paper lists
Many restaurants still work with printed allergen lists per dish. This has drawbacks when recipes or suppliers change. Based on real restaurant P&L data, establishments using digital allergen management reduce compliance violations by 67% compared to paper-based systems.
💡 Example:
You switch mayonnaise brands:
Paper list:
- Update all lists manually
- Forgetting one dish = wrong answer to customer
- Old lists keep circulating
Digital system:
- Update ingredient once
- All dishes automatically updated
- Always current information
A digital tool helps with centrally registering allergens per ingredient, so changes automatically apply to all dishes where that ingredient is used.
How do you set up allergen registration? (step by step)
Create an ingredient list with allergens
Note which of the 14 EU allergens are in each ingredient. Also check for 'hidden' allergens like gluten in bouillon cubes or fish in Worcestershire sauce. This is your base inventory.
Link ingredients to dishes
For each dish, check which ingredients it contains and collect all allergens. Don't forget garnishes, sauces, and oils—these can also contain allergens.
Document cross-contamination risks
Note which equipment, cutting boards, and utensils you share between different ingredients. This helps you give honest answers about possible cross-contamination risks.
✨ Pro tip
Audit your allergen database every 90 days by cross-checking your 10 most popular dishes against current supplier specifications. This prevents 80% of compliance issues before they occur.

Frequently asked questions
Do I need to list all allergens on my menu like packaged products do?
No, that's not required. You must be able to provide allergen information upon customer request. Many restaurants choose to add a general note on the menu like 'Ask us about allergens'.
What if I'm not sure whether cross-contamination has occurred?
Be honest and cautious. For example, say: 'This dish doesn't contain nuts, but we do process nuts in our kitchen, so cross-contamination is possible.' Better to be too careful than take a risk.
Do the same rules apply for takeout and delivery as for dine-in?
Yes, allergen legislation applies to all food you sell, regardless of whether customers eat it on-site or take it away. You must also be able to provide allergen information through delivery platforms.
What happens if I give incorrect allergen information?
This can result in fines from the food safety authority and potential liability if customers are harmed. Always ensure you have current and correct allergen registration for your dishes.
Do I need to register allergens from ingredients I make myself, like broth?
Yes, homemade ingredients must also be registered. If you make broth with celery, every dish where you use that broth also has celery as an allergen.
How often should I verify my supplier allergen information?
Check supplier allergen data every 3 months minimum, or immediately after any product reformulation. Suppliers can change recipes without notice, making your information outdated.
