A note typed into an app can be useful, but it is not automatically a confirmed safety conversation. The business needs accurate allergen information and a reliable process for carrying the requirement through preparation, packing and delivery.

Before you place the order

  • Check the current allergen information on the business’s own menu or website.
  • State the specific allergy clearly; do not rely on a vague phrase such as “no nuts” when peanut and named tree nuts need separate answers.
  • Ask about ingredients, substitutions and preparation practices relevant to cross-contact.
  • Confirm that the person answering can communicate the requirement to the kitchen.
  • If the information is incomplete or confidence is lost, choose another option rather than guessing.

The two information points required for takeaways

Before purchase

Information before you commit

The business must make information about regulated allergens available before the food is bought. This can be provided in writing on a menu or website, or through a clear telephone conversation.

At delivery

Information with the food

The information must be provided again when the food is delivered—for example through a label, written material or direct communication from the delivery person.

Third-party platforms

The ordering app is only one part of the chain.

Where a marketplace or delivery platform is involved, make sure the food business itself has received and confirmed the allergy information. A free-text note can be missed, truncated or separated from the kitchen ticket. Use the direct contact route where the business says a conversation is required.

When the order arrives

  • Ask the business to label the allergy order where several meals are being delivered.
  • Check the dish, label and any written allergen information before eating.
  • Reconfirm if packaging is unlabelled, a dish has been substituted or garnishes and sauces differ from what was agreed.
  • Do not assume removing a visible ingredient removes cross-contact or ingredients already used during preparation.
  • Keep the receipt and packaging if incorrect information or a reaction needs to be reported.

Emergency action

Suspected anaphylaxis needs immediate action.

Use an adrenaline auto-injector if available, call 999 and say you think it is an anaphylactic reaction. Follow your personal emergency plan.
