  Genetically Modified Food and Feed - Reports and Studies - Study on long-term effects of cultivation of GMOs 2009slide

This 2009 study addressed potential long-term (10-20 years) effects on health and the environment (including biodiversity) of genetically modified plants through their marketing and cultivation in the EU.

Which crops did the study cover?

Focus was on the 4 genetically modified crops most relevant to the EU:

  • Insect-resistant maize - Bt maize;
  • Herbicide-tolerant oilseed rape and sugar beet;
  • Starch-modified potato.

What did the study analyse?

The study covers:

  • Likelihood of occurrence of effects;
  • Identifies uncertainties and ways of minimising them e.g. modelling and improving monitoring methodology;
  • Actions to increase knowledge e.g. research areas.

It used literature reviews, online surveys and a workshop to rank the likelihood of adverse long-term effects from crop-trait combinations.

The report does not consider the possible magnitude of the risks due to lack of quantitative information, nor measures to mitigate them.
