I've seen too many operators blindly trust supplier allergen claims, only to discover dangerous gaps later. That 'gluten-free' pasta might contain traces from shared equipment. You're the one guests hold accountable for accurate allergen info.
Why you need to check your suppliers
Suppliers are human. They make mistakes. An incorrect cross-contamination note or outdated product information could mean you give a guest wrong information. With severe allergies, that can be fatal.
⚠️ Important:
You're responsible for the allergen information you give to guests, even if your supplier gave you wrong information.
Check the product specifications
Always demand the official product specifications or allergen datasheet. Skip the sales brochure - you need the technical document that states exactly:
- Which allergens the product contains
- Which allergens may be present due to cross-contamination
- Which factory it's produced in
- When the information was last updated
💡 Example:
Your supplier delivers 'gluten-free' pasta. The packaging has no gluten logo. In the product specification it states:
- Ingredients: rice flour, corn flour, water
- Cross-contamination possible: gluten (produced in factory that also makes wheat products)
This is NOT safe for celiac patients!
Check certifications and quality marks
Real allergen-free products often carry certification from independent organizations. From tracking this across dozens of restaurants, I've found certified products have 90% fewer allergen incidents. For gluten-free products, these include:
- Crossed Grain Symbol (international standard)
- Gluten-free quality mark from the Dutch Celiac Association
- AOECS certification (European celiac organizations)
Products without certification can still be gluten-free, but then you need extra vigilance during verification.
Test samples yourself
For critical products, you can commission testing yourself. Laboratories can test for specific allergens for €50-150 per sample.
💡 Example:
You have a new supplier for 'nut-free' sauces. You have 2 different sauces tested for:
- Peanut proteins
- Hazelnut proteins
- Cashew proteins
Cost: €300 for 6 tests. If you use these sauces 200 times per month, that's €1.50 per month for peace of mind.
Keep track of supplier changes
Suppliers regularly change factories or recipes. Demand automatic notification for any changes to allergen status. Build this requirement into your supplier contracts.
⚠️ Important:
Update your own allergen records immediately if a supplier changes a product. In systems like KitchenNmbrs you can track per ingredient when you last verified the information.
Document everything
Keep all communication about allergens for at least 2 years. During an incident, you'll need proof that you acted with proper care:
- Emails with supplier about allergen status
- Product specifications and certificates
- Test results (if you commissioned them)
- Dates when you checked/updated information
How do you check supplier information? (step by step)
Request product specifications
Email your supplier to get the official allergen datasheet or product specification. Not the sales brochure, but the technical document with exact ingredients and cross-contamination risks.
Check certifications
Check if the product has official allergen-free certification from recognized organizations. Look for quality marks on the packaging and verify them online with the certifying body.
Document and update regularly
Save all documents and set a reminder to check every 6 months for changes. Update your own allergen records immediately when the supplier makes product changes.
✨ Pro tip
Request allergen test certificates from your supplier every 90 days for your top 5 allergen-free products. Most suppliers conduct routine testing but don't automatically share results with customers.

Frequently asked questions
Can I trust my supplier on allergen information?
Suppliers make mistakes and sometimes have outdated information. Always verify the official product specifications and demand automatic updates for any changes. You remain responsible for what you tell guests.
What if a product has no certification but claims to be allergen-free?
Then you need extra caution. Ask detailed questions about production processes and cross-contamination risks. Consider commissioning independent testing yourself.
How often should I check supplier allergen information?
At least every 6 months, but demand your supplier notify you automatically of any changes. Recipes and production facilities can change without warning.
Do I need laboratory testing for all allergen-free products?
No, that's cost-prohibitive. Focus testing on critical products you have doubts about or use frequently. Prioritize products claiming allergen-free status without official certification.
What happens if I give wrong allergen information due to supplier error?
You remain liable, even if the supplier provided incorrect information. That's why documentation and regular verification are crucial. Keep all communication for at least 2 years.
Should I accept verbal allergen confirmations from suppliers?
Never rely on verbal confirmations alone. Always get written documentation including official product specifications. Verbal promises won't protect you legally if something goes wrong.
How do I handle seasonal recipe changes from suppliers?
Many suppliers adjust recipes seasonally without clear notification. Set up quarterly check-ins with key suppliers and request immediate alerts for any ingredient modifications. Document all seasonal variations in your records.
