Your staff's allergen knowledge can save lives. A wrong answer to a guest with an allergy can lead to a life-threatening reaction. You need systematic testing to maintain your team's allergen knowledge.
Why testing allergen knowledge is crucial
In the Netherlands, approximately 3% of adults and 8% of children have food allergies. An allergic reaction can develop within minutes and in the worst case can be fatal. Your staff is the last link between a safe or dangerous meal for the guest.
⚠️ Note:
Restaurants are legally required to provide correct allergen information upon request from the guest. This is EU legislation that applies throughout the Netherlands.
The 14 mandatory allergens your team must know
Your staff must know all 14 EU-mandatory allergens by heart:
- Gluten (wheat, rye, barley, oats, spelt, kamut)
- Crustaceans (shrimp, crab, lobster)
- Eggs
- Fish
- Peanuts
- Soy
- Milk (including lactose)
- Nuts (almond, hazelnut, walnut, cashew, pecan, brazil nut, pistachio, macadamia)
- Celery
- Mustard
- Sesame seeds
- Sulfur dioxide and sulfites (>10 mg/kg or liter)
- Lupin
- Mollusks (mussels, oysters, squid)
Practical testing methods for your team
1. Weekly allergen quiz
Organize a short quiz of 5-10 questions each week during briefing. Alternate between theory and practice.
💡 Example questions:
- Which allergens are in our Caesar salad?
- A guest is allergic to nuts. Which dishes can they NOT eat?
- What do you do if a guest asks if there's gluten in the fries?
- Which allergen is in Worcestershire sauce?
2. Mystery guest scenarios
Have colleagues take turns playing an allergic guest. Test how your staff responds to questions like "I'm allergic to crustaceans, what can I eat?"
3. Ingredient list blind test
Give your staff an ingredient list for a dish and have them name all allergens. This tests whether they also recognize hidden allergens.
💡 Example: Carbonara ingredients
- Spaghetti (contains: gluten)
- Eggs (contains: eggs)
- Bacon (may contain: sulfites)
- Parmesan cheese (contains: milk)
- Black pepper
Allergens: gluten, eggs, milk, possibly sulfites
What to do about wrong answers
If a team member makes a mistake during the test, it doesn't mean they're bad at their job. It means there's a knowledge gap that needs to be filled. I've seen this mistake cost the average restaurant EUR 200-400 per month in comped meals, negative reviews, and potential legal issues.
- Repeat the correct information immediately: Explain why the answer was wrong
- Have them review the allergen list for that dish again
- Test that same question again next week
- Pair them with an experienced colleague for extra guidance
Digital tools for allergen registration
Handwritten lists get lost and are hard to maintain. A digital system helps you record allergen information per dish and search it quickly. Your staff can then check on a phone or tablet which allergens are in a dish.
⚠️ Note:
An app doesn't register automatically. You're responsible for correctly entering the allergen information per dish.
Signs your team needs more training
Watch for these warning signs:
- Staff say "I'll go ask" for every allergen question
- They give different answers to the same question
- They guess or estimate instead of knowing for sure
- They forget to mention cross-contamination (e.g., fries in the same oil as fish)
Monthly evaluation and refresher training
Plan a monthly evaluation to discuss:
- Which allergen questions came up in the past month?
- Are there new dishes that contain additional allergens?
- Have suppliers changed recipes?
- Which team members need extra support?
How do you test allergen knowledge systematically? (step by step)
Create a question bank of 50+ questions
Gather questions about your own dishes, hidden allergens, and practical situations. Mix theory questions with practical scenarios like 'A guest calls and asks if you have gluten-free pasta'.
Test 5-10 questions weekly during briefing
Make it part of your standard briefing. Alternate between oral questions and practical simulations. Note who got which questions wrong for targeted refresher training.
Organize monthly mystery guest tests
Have colleagues take turns playing an allergic guest. Test realistic scenarios like 'I'm allergic to nuts, which dessert can I have?' This tests their practical skills.
Track results and plan refresher training
Note which topics are most frequently wrong and plan targeted training. Team members who consistently score well can help guide others.

Frequently asked questions
What do I do if an employee consistently gives wrong answers?
Provide extra guidance and have them work with an experienced colleague. If it doesn't improve, consider not having them talk to guests until their knowledge is up to standard. Allergen mistakes are too dangerous to tolerate.
Should I also test kitchen staff who don't have guest contact?
Yes, definitely. Kitchen staff must know which allergens are in each dish to prevent cross-contamination. They also need to know when to alert the chef if they're unsure.
How do I test knowledge about cross-contamination?
Ask practical questions like 'A guest is allergic to fish. Can you serve the fries?' or 'How do you prevent gluten-free pasta from getting contaminated?' Test both the theory and the practical steps they need to take.
