Claims made in a new report by the Rainforest Foundation and Future in Our Hands linking Brazilian soy companies Caramuru, Selecta and Imcopa to slave labor employment, violent land conflicts and illegal deforestation are "hard to believe, but very serious accusations,” Carlos Diaz, CEO of Danish feed giant BioMar told IntraFish.

The three companies are important suppliers of soy to European feed producers, since the Brazilian exporters are the only ones to supply non-genetically modified soy and therefore the only ones to meet EU regulations.
