Last week, a temp server at a busy downtown bistro told a guest their salmon dish was nut-free—not knowing the chef had switched to almond-crusted preparation that morning. The guest ended up in the ER with anaphylaxis, and the restaurant faced a $15,000 lawsuit. Training new staff on allergens isn't just paperwork—it's about preventing disasters.
Create a simple allergen card per dish
New employees need a quick overview of all dishes with their allergens. Skip complicated lists—make one card per dish instead.
💡 Example allergen card:
Pasta Carbonara
- Gluten (pasta)
- Eggs (carbonara sauce)
- Milk (parmesan)
NOT: Nuts, fish, shellfish
Each card should clearly state what IS in it and what's NOT. Guests ask about both, and you'll save time with complete information upfront.
Train the 5 most risky allergens
Of the 14 EU-mandated allergens, 5 cause the most reactions and are most dangerous. Focus here first:
- Nuts: Almond, hazelnut, walnut, cashew, pecan, brazil nut, pistachio, macadamia
- Gluten: Wheat, rye, barley, oats, spelt (found in bread, pasta, beer, sauces)
- Milk: Also in butter, cheese, cream, chocolate
- Eggs: Also in mayonnaise, pasta, pastries
- Fish/shellfish: Also in Worcestershire sauce, fish stock
⚠️ Watch out:
Allergens hide in unexpected places. Worcestershire sauce contains fish, many breads contain milk, and most sauces use gluten as thickener.
Use the 'doubt means no' rule
Train staff in one non-negotiable rule: Any uncertainty means 'no' and ask the chef. Better to make guests wait 2 minutes than call an ambulance—the kind of thing you only learn after closing your first month at a loss.
💡 Example conversation:
Guest: "Does the steak contain gluten?"
Employee: "The meat itself doesn't, but let me verify the marinade and sauce ingredients. Give me just a moment."
Much safer than: "No, it's just meat" (while the marinade actually contains gluten).
Create a cross-contamination protocol
Allergens transfer between dishes through knives, cutting boards, and pans. Set these kitchen rules:
- Separate cutting board for bread (gluten)
- Rinse knives between different dishes
- Fryer oil: separate for fish and shellfish
- Change gloves after contact with nuts
Digital registration for quick lookup
Paper lists disappear and are impossible to search during rush periods. A digital system helps you record allergen information per dish and find it instantly.
💡 Digital advantage:
Staff can check tablets or phones immediately to see which allergens are in each dish. Even during peak hours.
Recipe changes update the allergen list automatically.
Test knowledge before they hit the floor
Every new employee takes a short test with your 10 most popular dishes. They need 9 out of 10 correct before they can answer guest allergen questions.
⚠️ Watch out:
In the Netherlands, business owners must provide accurate allergen information. Mistakes can result in fines up to €10,000 or liability if allergic reactions occur.
How do you train a temp worker on allergen policy? (step by step)
Give an allergen card per dish
Create a card for each dish with all the allergens it contains. Also explicitly state what is NOT in it, because guests often ask about both. Laminate the cards so they don't get damaged.
Train the 'when in doubt say no' rule
Explain that they should say 'no' at any doubt and ask the chef. It's better to make a guest wait 2 minutes than to give a wrong answer.
Test knowledge with your top dishes
Have them take a short test with your 10 most popular dishes. Only when they can correctly name allergens in 9 out of 10 can they independently answer guest questions.
✨ Pro tip
Post laminated allergen cards at 3 key spots: expediting station, server pickup area, and near the POS system. Staff can verify information in under 15 seconds without leaving their stations.

Frequently asked questions
What if a temp worker makes a mistake with allergens?
As business owner, you're ultimately responsible for accurate allergen information. Provide thorough training and clear protocols. Always have the chef double-check uncertain situations.
How much time does proper training actually take?
With good allergen cards and clear rules, you can cover basics in 30 minutes. The knowledge test takes another 15 minutes.
Do I need to explain all 14 EU allergens immediately?
Start with the 5 most common: nuts, gluten, milk, eggs, fish/shellfish. Once they master these, add the remaining 9 allergens.
What if we don't have a digital system yet?
Paper allergen cards work fine, but keep them current. Recipe changes mean manually updating all cards—which gets tedious fast.
How do I prevent cross-contamination in the kitchen?
Use separate cutting boards for allergenic products, rinse knives between dishes, change gloves after nut contact. Train kitchen staff on these protocols too.
Should temp workers handle severe allergy requests differently?
Yes—severe allergies require chef consultation every time, regardless of staff confidence. Some guests carry EpiPens for good reason, so never take shortcuts with their safety.
