A question of segregation: 'GM-free' maize Bread in Portugal. Eurochoices, 15(1), 59-63. doi:10.1111/1746-692X.121211746-692Xhttp://hdl.handle.net/10400.15/1462We describe the maize supply chain in Portugal for maize bread, a traditional bread type. As this bread is not labelled as ‘contains genetically modified organisms’ it should not contain more than 0.9 per cent genetically modified ingredients. On the basis of interviews we identify a general lack of documentation of the presence or absence of genetically modified ingredients along the complete supply chain (farmers, traders, mills and bakeries). Part of this deficiency is probably driven by a lack of awareness of the labelling rules at the end of the supply chain.engPãoFarinha de milhoMilhoOrganismo modificado geneticamenteAbastecimentoPreçoComercializaçãoPanificaçãoInquéritojournal article10.1111/1746-692X.12121
