All genetically modified (GM) crops intended for use in food and feed must be assessed for their safety to humans and animals. The data and methodology used to conduct these assessments has been developed over many years. International organisations like the Food and Agriculture Organization (FAO) of the United Nations, the World Health Organization (WHO) and the Organisation for Economic Cooperation and Development (OECD) have been facilitating the harmonisation of food and feed risk assessment methodologies. The Codex Alimentarius Commission, established by FAO and WHO in 1963, has developed harmonised international food standards, guidelines and codes of practice and promoted coordination of all food standards work undertaken by international governmental and nongovernmental organisations.
