Requirements for allergen handling in meal software

This is the one area where a missing requirement has consequences beyond money. Evaluate it more carefully than anything else on your list.

Requirements in priority order

  1. Structured allergen fields

    Not free text. Text can only be read by a person who happens to look; structure can be checked automatically against every assignment.

  2. Validation of DEFAULTED meals

    The check most systems skip. A slot auto-filled at the cut-off is the assignment nobody reviewed, and therefore the most dangerous one.

  3. Warning at more than one point

    At assignment, on the production list, at packing, and on the label. A single warning gets missed on a busy morning.

  4. Customer-maintained records

    With changes taking effect on future assignments immediately. A record only the office can edit goes stale.

  5. Allergens on the printed label

    Derived from the recipe, not typed. The label is the only safeguard that reaches the person eating.

Test it with a defaulted meal

When evaluating, ask the vendor to demonstrate a customer with a dairy allergy whose slot is auto-filled at the cut-off with a dish containing dairy. Watch what happens.

A system that only validates customer-chosen meals will pass a normal demo and fail exactly where a real kitchen is most exposed, because nobody was watching when that meal was assigned.

What no software requirement covers

Cross-contamination, mislabelled supplier ingredients, and recipes whose ingredient lists were entered incorrectly. Software narrows one specific class of error and leaves those untouched.

They are process and training problems. Any vendor implying their software makes your kitchen allergen-safe is selling you something dangerous.

Common questions

What is the requirement most systems miss?
Validating meals that were assigned automatically at the cut-off rather than chosen by the customer. That is the assignment nobody reviewed and therefore the one most likely to cause harm.
Should allergen data be free text?
No. Free text can only be acted on by a person who happens to read it at the right moment, which on a busy morning is nobody. Structured fields can be checked automatically.
Does allergen software make a kitchen safe?
No. It narrows one class of error — a customer assigned a dish containing their allergen. Cross-contamination and incorrect recipe data remain process and training problems.
