Who is this for?

Shoppers managing a food allergy

Check the exact pack for ingredients you need to avoid and for relevant precautionary warnings. A general claim on the front cannot answer that individual question.

Parents and carers buying a snack

A bar or small bag may suit the occasion, but check its current ingredients, allergen warnings and age information before giving it to someone else.

Vegan shoppers who also check allergens

Vegan status answers a different question from allergy suitability. M&S labels its Vegan Marshmallows unsuitable for people with milk, nut or peanut allergies.

What should you check first?

Start with the current pack’s allergen information, then consider whether its portion format suits the occasion. The Food Standards Agency’s online survey on 15–20 December 2023 covered adults aged 16–75 in England, Wales and Northern Ireland; the figures below concern two distinct groups, not all shoppers.

Priority What to check Your needs
Allergen information Read the full ingredients list and any “may contain” wording. Check the physical pack rather than relying on an earlier purchase or saved listing. I need to check both ingredients used in the recipe and warnings relevant to the allergy I am shopping for.
Vegan labelling Check allergen warnings separately from the vegan claim. Read any explicit statement that a product is unsuitable for a named allergy. A vegan label alone cannot settle my allergy check. In the Food Standards Agency survey, 53% of respondents with a food hypersensitivity to an animal-origin allergen and 50% of regular shoppers for someone with such a hypersensitivity were aware before the survey that vegan products might still be unsuitable because of cross-contamination risk.
Portion format Distinguish a single bar from a small bag or individually wrapped pieces. Compare the exact product’s ingredients and warnings regardless of its weight. I want a snack I can take with me, but a 35g bar, a 50g bag and a pack of separate pieces are different formats; none is an allergy assurance.

Assumptions to avoid

  • Assuming vegan means suitable for an allergy

    M&S says its Vegan Marshmallows are not suitable for people with milk, nut or peanut allergies, despite the vegan label.

    Use the vegan claim to assess animal-product avoidance, then check ingredients and allergen warnings separately.

  • Applying one marshmallow recipe to another pack

    Tesco’s 50g plain marshmallows list pork gelatine, while Waitrose & Partners lists wheat glucose syrup and beef gelatine in its Pink and White Marshmallows.

    Check the exact flavour, pack size and current label rather than carrying a decision over from another product.

  • Treating a single bar as a lower-risk format

    Waitrose & Partners lists milk and soya ingredients in the 35g Mallow & Marsh Double Chocolate Bar, plus “may contain” warnings for egg, nuts and peanuts.

    Decide whether the ingredients and warnings fit the allergy requirements before choosing the bar for its format.

  • Relying on an old online ingredient list

    Waitrose & Partners warns that recipe changes can affect nutrition and allergen information.

    Read the current physical pack before purchase and before serving, particularly when buying for someone else.

Product and retailer references

These examples show why the label on the particular product matters more than the retailer or the marshmallow format.

Mallow & Marsh

Waitrose & Partners lists a 35g Double Chocolate Bar as an individually portioned marshmallow snack.

  • The listed bar is a single-snack format.
  • Its listing names milk and soya ingredients and says it may contain egg, nuts and peanuts.

Tesco

Tesco lists a 50g pack of plain marshmallows, a small bag rather than a single bar.

  • The 50g pack offers a different portion format from a chocolate-coated bar.
  • Its listed ingredients include pork gelatine; check the current pack for the information relevant to your purchase.

M&S

M&S lists Plant Kitchen Vegan Marshmallows in a 140g pack, not a single bar.

  • The vegan designation is relevant when avoiding animal products.
  • M&S explicitly labels this product unsuitable for people with milk, nut or peanut allergies.

Waitrose

Waitrose & Partners lists both own-label Pink and White Marshmallows and the Mallow & Marsh Double Chocolate Bar.

  • The listings allow shoppers to distinguish a plain pack from a chocolate-coated bar.
  • Their ingredients differ: the plain marshmallows list wheat glucose syrup and beef gelatine, while the bar lists milk and soya ingredients. Check each current label separately.

Questions about labels and packs

Does a vegan marshmallow label settle a milk, egg or nut allergy check?

No. Vegan labelling does not replace ingredient and precautionary allergen information. The Food Standards Agency’s 2024 research cautions against using vegan labelling as a substitute for allergen labelling, and M&S says its Vegan Marshmallows are not suitable for people with milk, nut or peanut allergies.

What does the Mallow & Marsh Double Chocolate Bar label say about allergens?

The 35g bar’s Waitrose & Partners listing names milk chocolate and soya lecithin and says it may contain egg, nuts and peanuts. Check the current pack against the particular allergy requirements; its single-bar format does not change those ingredients or warnings.

What must a UK food prepacked for direct sale label show?

According to a 2023 evaluation by the Food Standards Agency and Food Standards Scotland, requirements in force since 1 October 2021 mean food prepacked for direct sale must show its name and a full ingredients list with the 14 regulated allergens emphasised. Check the label on the product you are considering.

Should I check the label again if I have bought the same marshmallows before?

Yes. Waitrose & Partners warns that recipe changes can affect allergen information. Read the current physical pack rather than relying on a past purchase or an earlier online listing.
