The main purpose of this third meeting was to review and evaluate the evidence in support of precautionary labelling.If conditions had permitted, this meeting would have been held at FAO headquarters in Rome, Italy. Because of the travel restrictions and lock-downs due to the COVID-19 pandemic in many countries, the joint FAO/WHO secretariat was unable to convene a physical meeting. Therefore, the meeting was held as a videoconference using a virtual online platform.In view of the time differences in the countries of origin of the invited experts, the time for a videoconference was restricted to a 3-hour time slot (12:00?15:00 CET) each day. To make up for the usual daily length (8?10 hours) of a joint FAO/WHO scientific expert meeting and efficiencies associated with in-person meetings, virtual sessions were held daily over the course of three weeks.Dr Stefano Luccioli served as Chairperson.Dr N Alice Lee served as rapporteur.An Expert Committee, comprising scientists, regulators, physicians, clinicians and risk managers from academia, government and the food industry were selected to participate in the series of meetings of the FAO/WHO Expert Consultation on Risk assessment of Food Allergens (FAO and WHO, 2020a).This document summarizes the conclusions of this meeting and is made available to facilitate the deliberations of the Codex Committee on Food Labelling (CCFL) and Codex Committee on Food Hygiene (CCFH).
