This episode covers new research on food allergen risks in processing environments, including studies on allergen recovery from environmental swabs, cross-contamination in shared frying oil, and dispersal of allergenic food powders. Also discussed is an EU proposal to harmonize precautionary allergen labeling (PAL) requirements.
Following Codex recommendations for risk-based allergen Precautionary Allergen Labeling (PAL) and thresholds, the European Commission has posted a forthcoming draft act to its public feedback portal on harmonized requirements for the use of voluntary PAL statements.
A new study quantified the allergen cross-contamination that occurs in shared frying oil and evaluated the efficacy of different filters in removing allergen protein residues from oil.
This episode of Food Safety Five discusses scientific recommendations around ultra-processed food (UPF) definitions and policy, a study demonstrating the antimicrobial efficacy of common sanitizers in potato wash water, and a review outlining the food safety risks of edible flowers. Also discussed are regulatory and standards developments in the U.S., EU, and at the international level.
At its December 2025 Board Meeting, the UK Food Standards Agency (FSA) recommended that the agency support Codex proposals on precautionary allergen labeling (PAL) and seek UK alignment with Codex PAL recommendations.
To support Codex committee deliberations, an ad hoc joint FAO/WHO committee convened to recommend a gluten reference dose (RfD) in a risk-based precautionary allergen labeling (PAL) framework to ensure food safety for people with both celiac and immunoglobulin E (IgE)-mediated wheat allergies.
In November 2025, FDA will host a three-day, virtual public meeting on food allergen thresholds and their potential applications. Input received during the public meeting will help FDA determine next steps, establish priorities, and develop food allergen threshold approaches.
Harmonization of precautionary allergen labeling (PAL) requires the acceptance of reference doses for priority allergens. A new study found that PAL based on specific FAO/WHO-recommended thresholds would only elicit mild to moderate reactions in a small proportion of the allergic population.
To improve upon the commonly used precautionary, hazards-based approach to allergen labeling, FAO and WHO have developed a scientific approach to food allergen labeling based on actual risk, such as the likelihood and severity of an allergic reaction occurring.
Harmonized food allergen regulation at the EU level, and systematic monitoring led by a European reference lab, are necessary to protect consumers, argue researchers.
