Research Articles

The papers below relate only to the direct and indirect effects of the consumption of GM food and feed — ie evidence of (1) GM plant toxicity (this would include all animal feeding, immuntoxicity, inhalation etc trials) and (2) evidence of potential harm from the indirect effects of GM plants through inseparable or unavoidable production methods (e.g. the effects of added Roundup residues which are unique to Roundup Ready plants or possibly other HT plants). Some papers discuss the survival of DNA from GM plants in the mammal digestive system, since there are obvious health implications.

We do not include papers which show environmental damage, relating to GM plant toxicity to animals in the food web (these may result in environmental harm or increase the evidence of potential human toxicities) and relating to potential harm to the food web from the indirect effects of GM plants through inseparable or unavoidable production methods (this could include the rise in glyphosate resistant weeds that also increase the chance of their toxins contaminating human food supplies).

The papers towards the end of the list are recommended reviews which summarise earlier published raw data — and look for cause and effect relationships — but which do not necessarily report new experimental data.
