With the founding of the Food and Agriculture Organization (FAO) in 1945 and the World Health Organization (WHO) in 1948, they took the responsibility of covering food and health related issues, in the light of the international food standards.

At the World Health Assembly, held in 1953, it was confirmed that the broad usage of chemicals in food production and processing imposed itself as a new public health problem that required special attention.

On its 11^th session, held in 1961, the conference of FAO decided to establish the Codex Alimentarius Commission. In 1962 the Joint Conference of FAO and WHO for food standards requested from the Codex Alimentarius Commission to implement their Joint FAO/WHO program for food standards and at the same time create the Codex Alimentarius.

The World Health Assembly formally accepted the joint program of FAO/WHO for food standards, completely accepting the responsibility in relation with all food health aspects, on its 16^th session, held in May 1963, and accepted the Statute of the Codex Alimentarius Commission.
