Quick answer
Vegan or plant-based does not mean allergen-free. A product can contain allergenic plant ingredients or have a risk of unintended transfer from animal-origin allergens. Check the actual ingredients, precautionary information and preparation method for the customer’s specific request instead of using the dietary description as a safety assurance.
Understand the different questions a claim answers
FSA technical guidance distinguishes vegan descriptions from free-from allergen claims. A vegan label communicates different information and can coexist with a justified precautionary warning. It does not establish the absence of milk, egg or another allergen through unintended transfer.
“Plant-based” also needs accurate, non-misleading use. Staff should not infer a specific absence standard from the phrase without checking the actual product and evidence. A dietary description is a starting point for questions, not the answer to every allergy request.
Check the allergenic plant ingredients
| Product type | Possible information to check |
|---|---|
| Alternative drinks | The specific soya, nut, oat or other ingredients and precautionary information. |
| Plant-based sauces or spreads | Recipe components such as mustard, sesame, nuts or soya. |
| Meat-alternative preparations | Cereals, soya and other compound ingredients in the actual specification. |
| Bakery and desserts | Flours, nuts, seeds, fillings, toppings and bought-in mixtures. |
These are prompts, not claims that every example contains an allergen. Recipes vary and a substitute brand can have a different declaration. Check current evidence rather than making assumptions from product type.
Check handling as well as composition
An ingredient that meets a vegan specification may be prepared on shared equipment or served using utensils that also contact other foods. Review storage, preparation, cleaning and service for the particular allergen. Removing an obvious ingredient does not remove residues already transferred.
FSA precautionary-labelling guidance explains when assessed residual-risk warnings are appropriate and why they may appear alongside vegan labelling. Staff should not tell a customer to ignore a warning because the item is described as vegan.
Use a precise service conversation
Illustrative example: a customer with a milk-allergy request asks about a plant-based hot drink. Check the actual alternative drink, any flavouring or garnish, and the equipment and preparation arrangements. Answer the milk-allergen question from those facts rather than saying “it is vegan, so it is fine”.
If reliable information or an appropriate preparation arrangement is unavailable, explain that limitation before accepting the request. Do not decide that a trace amount will be acceptable for the person. Staff should provide accurate food information, not individual medical advice.
Keep menu language and training aligned
Review menus, online filters, icons and staff scripts so they do not equate dietary categories with absence claims. Use an understandable key and keep the regulated allergen information available independently of a vegan filter.
When recipes or suppliers change, update both the dietary description and the allergen evidence. The existing recipe-change guide and allergy-order handover guide can help connect the information and preparation chain. Verify that staff use the current wording under real service conditions.
Next steps
- Identify the customer’s specific allergen question.
- Check actual ingredients, precautions and shared preparation routes.
- Answer from the evidence rather than the dietary description.
- Review menu filters, claims and staff instructions after changes.
