VITAL, the Voluntary Incidental Trace Allergen Labelling programme published by the Allergen Bureau and now in its third edition, is a structured method for deciding whether a precautionary allergen statement is justified. It takes the measured or calculated cross-contact level, compares it against published reference doses for the allergen, and returns an action level that maps to a labelling outcome.
Why it works this way
The Union sets no threshold for unintended allergen presence, so the decision to print “may contain” is left to the manufacturer. Without a framework that decision is made defensively, which produces statements on products that carry no meaningful risk and devalues the statement everywhere else.
VITAL supplies the missing quantitative step. It works from reference doses derived from clinical challenge data, expressed as an eliciting dose predicted to provoke a reaction in a small defined proportion of the allergic population. Combined with the serving size of the finished food, that dose becomes a concentration in the product, and the assessment places the calculated cross-contact level into Action Level 1, where no precautionary statement is indicated, or Action Level 2, where the defined statement is used.
Two limits have to be stated plainly. It has no legal force in the Union. It is industry guidance, and a VITAL assessment does not by itself make a label compliant. And it applies only to unintended cross-contact. Anything intentionally present is an ingredient and is declared under Annex II to Regulation (EU) No 1169/2011 regardless of quantity.
What follows in practice
Use it as the documented rationale behind a precautionary statement or its absence, keep the underlying cross-contact data current, and be prepared to show the assessment to a customer or an auditor. Allergen management in mixed facilities sets out the controls the assessment depends on, and EU allergen labelling requirements covers the mandatory side.
