What to check before choosing
Start with the allergen you need to avoid and the exact bar you intend to buy. Then compare what its Fairtrade claim covers and which cocoa percentage you prefer.

What to check |
Your needs |
| Allergen wording |
Read the current ingredients, ‘may contain’ statement and any ‘not suitable for’ wording on the exact bar. The Food Standards Agency explains that precautionary wording signals possible unintended allergen presence through cross-contact. |
I need to distinguish an ingredient in the recipe from a warning about possible cross-contact, and avoid wording that conflicts with my allergy requirements. |
| Fairtrade claim |
Identify the mark and any named Fairtrade ingredient or mass-balance statement. The Fairtrade Foundation says its classic black-background mark covers all ingredients that can be Fairtrade-certified; its Fairtrade Sourced Ingredient mark identifies a specified sourced ingredient. A mass-balance claim does not establish physical separation in an individual bar. |
I want to know whether the claim covers all certifiable ingredients or a named ingredient, without treating sourcing information as an allergen clearance. |
| Cocoa and recipe |
Compare the stated cocoa percentage and the ingredients of the exact plain, filled or flavoured variant. Neither a higher percentage nor a shorter ingredient list overrides an allergen warning. |
I’m choosing a cocoa percentage to suit my taste, but I still need to assess this particular recipe and its precautionary wording. |

Tony's listing describes Fairtrade sourcing for cocoa, sugar and cocoa butter; check the current pack to see the precise claim.

Questions about labels and allergens
Does vegan dark chocolate clear a bar for a milk allergy?
No. Vegan describes the recipe, not every possible cross-contact warning. Divine’s vegan 70% bar says it may contain milk, and Lindt says its vegan-recipe 99% bar is not suitable for people with a milk allergy because it is made in a facility that uses milk.
What does ‘may contain’ mean on a UK food label?
It is a precautionary warning that an allergen may be unintentionally present. The Food Standards Agency explains that this can arise through cross-contamination; check the warning against the specific allergen you need to avoid rather than treating an ingredient list alone as clearance.
Do the Fairtrade marks cover the same ingredients?
No. The Fairtrade Foundation says its classic black-background mark indicates that all ingredients that can be Fairtrade-certified are certified. Its Fairtrade Sourced Ingredient mark identifies a specified Fairtrade-sourced ingredient, so check which ingredient the claim names.
Can I use online allergen information to choose a bar?
Use it to narrow your options, then read the current pack before buying. M&S advises shoppers that product information can change and that its online ingredients and allergen details should not replace the product label.
