  2. 2. Structure of presentation1. What is ‘GM’?2. Potential risks for human health3. Experiment on rats fed with GM maize4. Food labelling5. Conclusions6. Resources7. Q&A 2
  3. 3. What is ‘GM’?Inserting genetic material into DNA Examples: ‘super pigs’ with human growth genes, fish with cattle growth genesSwitching on/off certain genes Examples: ripening fruits>70% of processed foods include GM ingredients 3 http://news.bbc.co.uk/1/hi/sci/tech/3711507.stm
  4. 4. Risks WHO (2012) ‘G Mfo o d s c urre ntly a va ila ble o n the inte rna tio na l m a rke t ha ve p a s s e d ris k a s s e s s m e nts a nd a re not likely to present risks for human health.

  5. 5. The Experiment rats fed for two years on:3 concentrations of non-GM maizeGM maize 30% male, 20%50% male, 70% female diedfemale died earlier some alsoPalpable tumours developed tumoursKidney disease and but later than the firstliver disease more groupcommon 5
  6. 6. Food Labelling84286 GM95413 organic8235 conventionally grownhttp://www.gmo-compass.org/features/zoomimage.php? image=/data/imagescontent/regulation/050_dressing_label_zoom.jpg&width=500&height=332 6
  7. 7. Conclusionsno data showing that GM is not harmfulbe up-to-date with EU food regulationsmore research needed in this field 7
  8. 8. Resources Séralini G, Clair E, Mesnage R et al. Long term toxicity of a Roundup herbicide and a Roundup-tolerant genetically modified maize.
