On July 7, 2026, the Codex Alimentarius Commission adopted new international guidance on precautionary allergen labelling (PAL) as an annex to the General Standard for the Labelling of Pre-packaged Foods (CXS 1-1985). The global standard-setter's 49th Session, held in Geneva from July 6 to 10, 2026, agreed that "may contain" statements should be used only after a science-based risk assessment and only when residual allergen risk cannot be controlled through good manufacturing practices.
Food allergies affect an estimated 4.3 percent of the global population, yet PAL use varies widely across products and countries and remains unregulated in many markets. The new text aims to make precautionary statements meaningful, consistent and risk-based for consumers and industry, complementing the existing Code of Practice on Food Allergen Management for Food Business Operators (CXC 80-2020).
What changed under the new Codex PAL guidance?
The annex establishes a harmonized, risk-based approach: PAL should not substitute for good allergen management, but should apply only after a food business has implemented appropriate controls and demonstrated through a scientific risk assessment that unintended allergen presence still poses a residual risk. The recommendations are underpinned by scientific advice from seven joint FAO/WHO expert consultations, giving governments and industry a common framework to decide when "may contain" warnings are warranted.
The guidance targets the inconsistency that today leads some consumers to avoid foods that are safe for them while others lose confidence in warnings and ignore them. By tying PAL to a documented risk assessment rather than precautionary default use, Codex raises the bar for when a statement is justified at all. The official FAO release frames the text as a step toward making "may contain" statements science-based and consistent worldwide.
Who is impacted, and is the guidance binding?
Codex texts are voluntary: they are not self-executing law and create no direct obligation until a national or supranational legislator transposes or references them. The immediate audience is therefore food manufacturers and compliance teams that align labelling practices with the international benchmark, together with regulators that rely on Codex as a scientific reference in national food labelling rules and in WTO SPS disputes.
Global food manufacturers, in particular the large confectionery, dairy and packaged-goods companies whose products share production lines and supply chains across allergens, are the most exposed. For them, the guidance sets the direction of travel that national regulators in major markets typically follow within one to three years of Codex adoption.
What should compliance teams do now?
Even before national transposition, manufacturers should audit current PAL use against the risk-based test the annex now codifies. The practical steps are to confirm that each "may contain" statement rests on a documented risk assessment, verify that good allergen management practices are in place beforehand, and retire precautionary labels that cannot be justified by residual-risk evidence.
Teams should also map where the guidance interacts with existing obligations. The General Standard for the Labelling of Pre-packaged Foods (CXS 1-1985) governs allergen declaration, while CXC 80-2020 sets the management-practice layer the new PAL test builds on.
| Obligation under the new annex | Trigger | Who acts |
|---|---|---|
| Conduct a scientific risk assessment of unintended allergen presence | Before applying any PAL statement | Food business operator |
| Implement good allergen management practices | As a prerequisite, not a substitute for PAL | Food business operator |
| Apply PAL only when residual risk remains | After controls and assessment show residual risk | Food business operator |
| Transpose into binding national labelling rules | Future, jurisdiction by jurisdiction | National regulators |
Continuous, per-jurisdiction monitoring surfaces this kind of benchmark shift the moment Codex publishes it, well before national transposition turns voluntary guidance into binding labelling rules.

What to do next
Check whether your product portfolio carries PAL statements that lack a documented risk assessment, brief your food safety and labelling teams on the risk-based test the annex codifies, and track which jurisdictions move first to transpose CXS 1-1985's new annex into national law. Obsidian follows Codex adoption and each national transposition as it lands, so the moment voluntary guidance becomes a binding rule you are already prepared.
