At the request of Codex, FAO and WHO held a series of expert meetings on the risk assessment of food allergens since 2020 and published the meeting reports, including Part 1: Review and validation of Codex Alimentarius priority allergen list through risk assessment; Part 2: Review and establish threshold levels in foods for the priority allergens; Part 3: Review and establish precautionary labelling in foods of the priority allergens; Part 4: Review and establish exemptions for the food allergens; Part 5: Review and establish threshold levels for specific tree nuts (Brazil nut, macadamia nut or Queensland nut, pine nut), soy, celery, lupin, mustard, buckwheat and oats.
In response to the request from Codex for scientific advice on reference dose (s) (RfDs) and concentration for cereals containing gluten and gluten, FAO and WHO are convening an expert consultation to provide recommendation on the level of RfDs and concentration for cereals containing gluten and gluten.
