The world needs a global coalition with grass-root involvement; not insular and impractical initiatives imposed by a privileged few.
Agencies such as the World Health Organization/CODEX Alimentarius, United Nations, the World Trade Organization, the World Food Program, etc., already exist to drive needed harmonization. Education needs to be provided along with enforcement but education needs to be given higher priority.
All nations already subscribe to international law that provides a basis for any required enforcement of civility. This international law does not preclude the enforcement of each country's national laws. The call is for a true global consideration in the enforcement of national laws with a strong sense of deliberate global collaboration in all aspects pertaining to the production, provision and protection of food for the benefit of consumers everywhere.
One thing appears certain: World food problems (food supply inequity, food distribution constraints, food fraud, food safety problems, etc.) are continuing to mount and some things now seen as grand global initiatives will soon be small talk. What the world needs are truly collaborative, non-exclusive, broad scoped strategies that are free of counter-productive hidden agendas.
