Three Major GMO’s Approved for Food and Feed Found Unsafe

Int J Biol Sci 2009; 5(7), 706-726

Caen, 14 December 2009: In what is being described as the first ever and most comprehensive study of three major GMOs  about  assessing  the  effects on mammalian health, researchers  from CRIIGEN and Universities of Caen  and Rouen have highlighted a number of new sex  and often dose dependent side effects  linked  with  their  consumption.  Their  study  of  the  90-day  feeding  trials  data  of  insecticide producing Mon 810, Mon 863 and Roundup herbicide absorbing NK 603 varieties of GM maize clearly underlines adverse impacts on kidneys and liver, the dietary detoxifying organs, as well as different levels of damages  to heart,  adrenal  glands,  spleen  and haematopoietic system. Ironically,  the  confidential  raw data  of  Monsanto  about  feeding  trials  on  rats  that  these researchers  have  analyzed  allowed  the international authorization of these three commercialized GMOs in
different parts of the world.

Although different  level of adverse  impact on vital organs were noticed between  the  three GMOs,  the research done by J. Spiroux de Vendomois, F. Roullier, D. Cellier and G.E. Seralini and appeared  in the International Journal  of Biological Sciences shows specific effects  associated with consumption of each GMO, differentiated by sex and dose. Their research follows in the wake of European Governments obtaining the raw data related to feeding of rats for 90 days and making it publically available for scrutiny and counter-evaluation.

The  researchers  have  concluded  that  all  the  3 GMOs  that  they  have  studied  contain  novel  pesticide residues that will be present in food and feed and may pose grave health risks to those consuming them. They have, therefore, called for immediate prohibition on the import and cultivation of these GMOs and have  strongly  recommended  additional  long-term  (up  to 2  years) and multi-generational  animal  feeding studies on  at  least  three  species  to provide  true scientifically  valid data on  the  acute  and  chronic  toxic effects of GM crops, feed and foods.

CRIIGEN denounces  in  particular  the  past  opinions  of  EFSA, AFSSA and  CGB,  committees  of European and French Food Safety Authorities, and others who  spoke on the  lack of  risks on  the  tests which were conducted  just for 90 days on rats to assess the safety of these three GM varieties of maize. While criticizing their failure to examine the detailed statistics, CRIIGEN also emphasizes the conflict of interest and incompetence of these committees to counter expertise this publication as they have already voted positively on the same tests ignoring the side effects.
