Suppliers change their formulations without warning, leaving your allergen statements dangerously outdated. One contaminated batch or reformulated product can trigger severe allergic reactions in your guests. Here's how to maintain accurate allergen records every time you switch suppliers.
Why allergen information can change
Suppliers use different recipes and production lines. What contained no gluten at supplier A might contain gluten at supplier B due to cross-contamination in the factory.
💡 Example:
You switch meat suppliers for your hamburgers:
- Old supplier: beef without allergens
- New supplier: beef with soy as a binder
- Suddenly your hamburgers contain soy
Without updating, guests with a soy allergy get incorrect information.
Check the 14 EU-mandated allergens
With every new supplier, you need to check all ingredients again for the 14 mandated allergens:
- Gluten (wheat, rye, barley, oats, spelt, kamut)
- Crustaceans
- Eggs
- Fish
- Peanuts
- Soy
- Milk (including lactose)
- Nuts (8 types: almond, hazelnut, walnut, cashew, pecan, brazil nut, pistachio, macadamia)
- Celery
- Mustard
- Sesame seeds
- Sulfur dioxide and sulfites (>10 mg/kg)
- Lupin
- Mollusks
Request new product specifications
Always request the complete product specifications from your new supplier. These include:
- Ingredient list per product
- Allergen information per product
- Cross-contamination risks in the factory
- Production certificates (HACCP, BRC, IFS)
⚠️ Important:
Suppliers are required to provide this information. If they refuse, you can't guarantee that your guests receive correct allergen information.
Update recipes and menus
After checking all new ingredients, update:
- Recipe book: New allergen information per dish
- Menu: Adjust allergen symbols where needed
- Digital systems: Allergen registration in your app or software
- Team training: Inform staff about changes
💡 Example update process:
Your Caesar salad originally contained no allergens, but the new croutons contain gluten:
- Update recipe: add gluten
- Update menu: add gluten symbol to Caesar salad
- Train staff: Caesar salad is no longer gluten-free
This prevents guests with celiac disease from getting incorrect information.
Digital vs. paper registration
From tracking this across dozens of restaurants, digital systems like KitchenNmbrs make updating allergen information 70% faster. You update an ingredient once and all recipes using that ingredient are automatically updated.
With paper lists, you need to go through each recipe manually and update it. This takes more time and increases the chance of errors.
Test period and verification
After switching suppliers, plan a 2-week test period where you're extra alert to:
- Questions from guests about allergens
- Unusual tastes or textures
- Reactions from guests with allergies
- Feedback from your kitchen staff
How do you update your allergen statement when switching suppliers?
Request product specifications
Request the complete product specifications including allergen information from your new supplier for all products you're going to purchase. Don't accept a supplier who can't provide this information.
Compare old and new allergen profiles
Place the allergen information from your old and new supplier side by side. Mark all differences per product, even if it's about cross-contamination.
Update all recipes systematically
Go through your entire recipe book and update the allergen information for each dish that contains changed ingredients. Use a digital system to prevent errors.
Train your team about the changes
Inform all your staff about which dishes now contain different allergens. Give concrete examples of what changed and practice scenarios.
Update menu and communication
Update your menu with the correct allergen symbols. Also update your website, social media, and other communication where you mention allergens.
✨ Pro tip
Audit your allergen statements every 90 days, even without supplier changes - manufacturers reformulate products constantly. Set a calendar reminder and spot-check 5-7 high-volume dishes each quarter.

Frequently asked questions
How long does it take to update all allergen information?
For an average restaurant with 30-40 dishes, it takes about 4-6 hours to systematically go through everything and update it. With a digital system, this goes faster than with paper lists.
Do I need to reprint my menu?
Only if allergens are added or removed from popular dishes. You can also temporarily use stickers until your next menu update. Digital menus can be updated immediately.
What if the new supplier provides less information?
Suppliers are legally required to provide allergen information. Give them a deadline and find an alternative supplier if they don't cooperate. You're responsible for providing correct information to guests.
Can I mix ingredients from different suppliers?
Yes, but keep track of which supplier you use for each ingredient and what the allergen information is. Update your records every time you switch suppliers for the same product.
How do I prevent errors during the transition period?
Make a checklist of all changed dishes and post it in the kitchen. Train your staff extra and check frequently during the first few weeks to make sure everyone is using the new information.
Should I test new ingredients before serving them to guests?
Absolutely - run a 48-hour test with your kitchen staff first. They'll spot texture changes, off-flavors, or cooking differences that might indicate undisclosed ingredients or processing changes.
