Time to ACT-UP: Update on precautionary allergen labelling (PAL)

Area of Science:

• Food Science
• Allergen Management
• Regulatory Affairs

Background:

• Precautionary Allergen Labelling (PAL) communicates risks of unintended allergen presence (UAP) in food products.
• Inconsistent and unregulated PAL use, highlighted by the World Allergy Organization (WAO), reduces consumer utility.
• International bodies like WHO, FAO, and the Codex Committee on Food Labelling (CCFL) are addressing PAL regulation.

Purpose of the Study:

• To summarize current data on PAL to inform systematic application.
• To support the development of global food standards for allergen labelling.
• To identify challenges and prospects for a regulated PAL framework.

Main Methods:

• A non-systematic review of literature and expert consultations.
• Analysis of global legislation concerning allergen labelling and UAP.
• Examination of international efforts to rationalize PAL.

Main Results:

• While many countries regulate allergen ingredient declaration, few address UAP.
• Non-regulated PAL leads to interpretation difficulties and inconvenience for allergic individuals.
• Existing efforts to standardize PAL have shown mixed success.

Conclusions:

• Prospects exist for developing effective, homogeneous global legislation for PAL.
• Areas of uncertainty may impede international agreement on a regulated PAL framework.
• The CCFL's consideration of the FAO/WHO Expert Consultation is a critical juncture for PAL regulation.
