How to read chocolate allergen labels

Two different statements appear on every chocolate package, they answer different questions, and only one of them is legally required.

beginner

An invented, unbranded chocolate label in two panels. The first is an ingredients declaration in which the words MILK and SOYA lecithin are emphasised in bold, annotated as legally required with a defined scope. The second is a dashed panel reading may contain nuts and peanuts, annotated as voluntary, not standardised, and not a graded scale, with the note that its absence is not an assurance. — Two statements, two different questions. Only the ingredient declaration is a legal requirement, and the absence of a may-contain line is not an assurance. Generated from ChocolateHQ’s own records rather than drawn or photographed.

If you read nothing else

The ingredient list is a legal declaration about the recipe. 'May contain' is a voluntary, unstandardised statement about the equipment — and its absence proves nothing.

The ingredient declaration

In the EU and UK, a defined list of allergens must be declared and emphasised — typographically distinguished — wherever they are used as ingredients. Milk, nuts, peanuts, soya, cereals containing gluten and sesame all appear regularly in chocolate products.

This part is a legal requirement with a defined scope. If milk is in the recipe, it is in the list, and it is emphasised. That is a reliable statement about composition.

The precautionary statement

'May contain', 'made in a factory that also handles', 'not suitable for' — these are voluntary in most jurisdictions, are not standardised, and are not a graded scale. Two manufacturers with identical risk may label differently.

Crucially, the absence of a precautionary statement is not an assurance. It may mean a rigorous assessment found no material risk, or it may mean nobody wrote one. You cannot tell which from the package.

What this means in practice

For a preference or an intolerance, the ingredient list is generally what you need and it is reliable.

For a diagnosed allergy, the ingredient list answers only half the question, the precautionary statement is unstandardised, and the meaningful assurances come from dedicated facilities and manufacturer allergen policies. Loose chocolates from an open counter carry a risk that no packaging statement addresses.

What any of this means for an individual is a clinical question. This guide describes what the statements assert.
