Seasonal ingredients often hide allergens you'd never expect to find. That fresh asparagus might've been processed alongside celery, or your artisanal mushroom blend could carry traces from shared equipment. Here's your safety protocol for staying compliant with EU allergen rules.
Check all 14 EU-mandated allergens
Every seasonal product needs screening against all 14 EU allergens, regardless of how 'natural' it appears:
- Gluten (wheat, rye, barley, oats, spelt, kamut)
- Crustaceans
- Eggs
- Fish
- Peanuts
- Soy
- Milk (including lactose)
- Tree nuts (8 types: almond, hazelnut, walnut, cashew, pecan, Brazil nut, pistachio, macadamia)
- Celery
- Mustard
- Sesame seeds
- Sulfur dioxide and sulfites (>10 mg/kg)
- Lupine
- Mollusks
⚠️ Heads up:
Even 'natural' products can contain allergens due to cross-contamination during transport, storage, or processing at the supplier.
Request information from your supplier
Suppliers must legally provide allergen data. Don't accept orders without these documents:
- Product specification with complete ingredient list
- Allergen declaration per product
- Cross-contamination risks in their production process
- Processing methods (washed, cut, packaged)
💡 Example:
You're buying white asparagus for the first time from a new supplier:
- Product looks 'clean' → but is washed in water where celery is also washed
- Risk: cross-contamination with celery
- Result: you must list celery as a possible allergen
Always ask first, then order.
Register in your system
Document allergen information immediately in your recipe management system. From tracking this across dozens of restaurants, I've seen too many seasonal ingredients slip through without proper documentation. Record these details for each product:
- Present allergens (according to supplier)
- Possible cross-contamination risk
- Registration date
- Supplier information
Digital systems automatically apply this information to all dishes containing the product.
💡 Example registration:
New seasonal mushrooms (chanterelles):
- Supplier: Farmer Johnson
- Allergens: none directly, but cross-contamination risk with celery
- Registered: March 15, 2024
- Used in: risotto, pasta, sauce
All 3 dishes now automatically get 'may contain celery' in their allergen list.
What if information is missing?
Small suppliers often lack detailed allergen declarations. You can't just wing it - here's your action plan:
- Ask specifically about processing methods
- Check the production facility - what other products are processed there?
- Be cautious - if in doubt, list the allergen as 'may be present'
- Look for alternatives if the supplier can't provide information
⚠️ Heads up:
If you're unsure, always list the allergen as 'may be present'. Better safe than sorry with guest allergic reactions.
Inform your team
Your service staff needs immediate updates about new seasonal products. They should confidently explain to guests:
- Which new dishes contain the seasonal product
- Which allergens are involved
- Alternatives for guests with those allergies
💡 Example team communication:
"Starting today, we have fresh morels in 3 dishes:"
- Risotto with morels → may contain celery due to cross-contamination
- Veal with morel sauce → may contain celery
- Appetizer mushroom soup → may contain celery
Alternative for guests with celery allergy: risotto with zucchini.
How do you register allergens for seasonal products? (step by step)
Request allergen information from your supplier
Before you order, ask for a product specification with all 14 EU allergens and cross-contamination risks. Do this in writing (email/WhatsApp) so you have proof.
Register in your recipe system
Record the seasonal product as a new ingredient with all allergen information. Add the date, supplier, and any cross-contamination risks.
Update all existing recipes
Check which dishes will contain the new seasonal product and update their allergen lists. Inform your team about the changes and possible alternatives.
✨ Pro tip
Send new suppliers a standard allergen questionnaire covering all 14 EU allergens within 48 hours of first contact. This prevents last-minute surprises and ensures you never miss critical allergen data.

Frequently asked questions
Do I need to list allergens if they 'may be present' due to cross-contamination?
Yes, EU regulations require you to list cross-contamination risks as well. Use phrases like 'may contain traces of' or 'may be present'.
What if my supplier doesn't have allergen information?
You shouldn't use the product without risk assessment. Find another supplier or list all possible allergens as 'may be present' based on the production environment.
How often should I update allergen information from the same supplier?
Check at least once per season if anything has changed in their production process. Contact them immediately if you have any doubts or guest complaints.
Can I be less strict with allergens for organic products?
No, organic products fall under the same EU regulations. Organic products can also have cross-contamination or unexpected allergens.
What happens if I forget to list an allergen?
If a guest has an allergic reaction, you face liability risk and possible fines from food safety authorities. That's why it's always better to be overly cautious than too lax.
Should I test seasonal products myself for allergens?
No, rely on official supplier documentation and certifications. Home testing isn't legally valid and can give false results.
How do I handle allergen info for foraged ingredients?
Foraged ingredients carry the highest risk since processing history is unknown. List all potential allergens based on the foraging environment and preparation methods you'll use.
