Many restaurant owners think they can handle allergic reactions with just a quick apology and a replacement dish. But an allergic reaction creates both an immediate safety emergency and a legal documentation requirement. Both need your full attention.
Immediate action when an allergic reaction occurs
Speed matters when a guest reports an allergic reaction. Your first priority is always the guest's safety—paperwork comes second.
⚠️ Note:
For severe reactions (difficulty breathing, facial swelling): call 112 immediately. Registration comes later.
- Stop serving the dish in question immediately
- Ask the guest about the severity of symptoms
- Offer help (water, call 112 if needed)
- Note the time, dish, and symptoms right away
What you need to register
Your HACCP records must include every allergen-related incident. This documentation protects you during food safety inspections and provides legal coverage.
💡 Example registration:
Date: March 15, 2024, 20:15
- Dish: Caesar salad
- Reported symptoms: itching in mouth
- Possible cause: anchovies (fish) not mentioned
- Action: guest given new salad without anchovies
- Staff: chef John, server Maria
Keep these records for at least 2 years. During a food safety inspection, you'll demonstrate that you handle incidents seriously and make continuous improvements.
Investigating the cause
After ensuring the guest's safety, investigate what went wrong. This prevents future incidents and shows you're taking responsibility seriously.
- Check the recipe: are all allergens listed?
- Review the menu: are all allergens mentioned?
- Ask your staff: did cross-contamination occur?
- Check supplier information: new ingredients?
💡 Common causes:
- Anchovies in Caesar dressing (fish allergen)
- Sesame seeds on burger buns (sesame allergen)
- Cross-contamination via cutting board or fryer
- New supplier with different composition
Implementing corrective actions
An incident creates an opportunity to strengthen your processes. Don't just record what happened—document your response too. This is one of the most common blind spots in kitchen management: treating incidents as isolated events rather than learning opportunities.
- Update recipes with missing allergens
- Correct menu information if it's inaccurate
- Train staff on new procedures
- Introduce additional checks
💡 Example corrective action:
Problem: fryer cross-contamination (gluten in gluten-free fries)
- Solution: separate fryer for gluten-free products
- Training: all cooks trained on new procedure
- Check: daily verification of which fryer is used for what
Digital vs. paper registration
Many kitchens still rely on paper forms for incident registration. But paper gets lost, and searching through old records becomes a nightmare.
- Paper: Can get lost, difficult to search
- Digital: Always available, easy to find
Apps like KitchenNmbrs include incident modules where you can quickly record what happened. During a food safety inspection, you'll find all records within seconds.
⚠️ Note:
An app doesn't register automatically. You still need to enter the incident yourself. The advantage is in the ease of searching later.
Communication with the guest
Your response to an allergic reaction often determines whether a guest returns or leaves a scathing review online.
- Take it seriously, even with mild symptoms
- Apologize sincerely
- Explain what you'll do to prevent it from happening again
- Offer compensation (new dish, waived bill)
Many guests appreciate a follow-up call later to check how they're feeling. This shows you view the incident as more than just a business inconvenience.
How do you register an allergic reaction? (step by step)
Take care of the guest first
Help the guest immediately and call 112 for severe reactions. Registration comes only after first aid.
Note the basic information
Write down: date, time, dish, reported symptoms, and which staff members were involved. Do this as soon as possible after the incident.
Investigate the cause
Check the recipe, the menu, and ask your staff what went wrong. Document your findings.
Plan corrective actions
Determine what you'll do to prevent it from happening again. Update recipes, train staff, or adjust procedures.
Keep the registration
Save everything in your HACCP records. Keep it for at least 2 years for potential inspections or legal questions.
✨ Pro tip
Document the exact time and take photos of the dish within 15 minutes of the incident report. Ingredients can change between prep batches, and visual evidence helps identify the specific cause.
Calculate this yourself?

Frequently asked questions
Do I need to register every allergic reaction, even mild ones?
Yes, register every report of an allergic reaction. Even mild symptoms can reveal structural problems with your allergen information or kitchen procedures.
What if the guest doesn't want me to register it?
You register for your own HACCP records, not for the guest's benefit. You don't need personal details, just the incident facts.
How long do I need to keep incident records?
At least 2 years for standard HACCP compliance. For serious incidents or potential legal issues, consider keeping them longer.
Do I need to inform food safety authorities about every allergic reaction?
Only for serious incidents requiring hospitalization. For mild reactions, your internal registration is sufficient unless authorities request it during inspections.
Can I be held liable for allergic reactions?
Potentially, if you knowingly provide incorrect allergen information or fail to take reasonable precautions. Proper documentation helps protect your legal position.
What do I do if I can't identify what caused the reaction?
Register that the cause is unknown and document your investigation steps. Sometimes patterns emerge later that reveal the actual trigger.
