Across much of the world, people have overwhelmingly opposed the genetic modification of crops for food production. Yet production and use of genetically-modified crops continue to expand. Two little-known companies - Cargill and Archer Daniels Midland - have been instrumental in the introduction of the technology. These two companies, principally involved in distribution and primary processing of commodities, are responsible for around two thirds of US soya and maize exports. This report deals with the ways in which Cargill and ADM control the supply of GM vs non-GM crops, largely in industrialised countries (in North America, Europe and East Asia).
