Recent Evidence Confirms Risks of Horizontal Gene Transfer

Recent Evidence Confirms Risks of Horizontal Gene Transfer 

I-SIS Contribution to ACNFP/Food Standards Agency Open Meeting 13 November 2002

Horizontal gene transfer is one of the most serious, if not the most serious hazard of transgenic technology. I have been drawing our regulators’ attention to it at least since 1996 [1], when there was already sufficient evidence to suggest that transgenic DNA in GM crops and products can spread by being taken up directly by viruses and bacteria as well as plant and animals cells.

Predicted Hazard of Gene Therapie a Reality

Predicted Hazard of Gene Therapy A Reality

I-SIS was almost a lone voice warning of cancer from foreign genes inserting into the genome in ‘gene therapy’ and other exposures to transgenic DNA. Regrettably, this has now become reality.
Dr. Mae-Wan Ho calls for a comprehensive review of gene therapy and other transgenic technologies, for they carry similar risks.

The French team that made news in 2000 treating children with severe combined immune deficiency (SCID) had to call a halt to the gene therapy trial. One of the ten children treated has developed what looks like leukaemia.

Metabolism of  14C-Glufosinate and 14C-N-Acetyl-Glufosinate in lactating goats en laying hens.


Glufosinate ammonium (ammonium homoalanin-4-yl(methyl)phosphinate) and N-acetyl-glufosinate (the major metabolite in glufosinate resistant crops) were administered orally to lactating goats and laying hens. Goats were dosed with either glufosinate ammonium or N-acetyl-glufosinate for four and three days, respectively at approximately 92 ppm in the diet representing 60-75 times the maximum residue level expected in ruminant feed. Hens were dosed for fourteen days with either glufosinate ammonium or N-acetyl-glufosinate at approximately 26 ppm, representing 10 times the maximum residue level in poultry feed. Total radioactive residue levels were determined for tissues, eggs and milk (as appropriate). Glufosinate and N-acetyl-glufosinate were rapidly eliminated from ruminants and poultry, with a similar metabolic profile being found for each compound in both species. Glufosinate was metabolized to MP-propionic acid (3-methylphosphinicopropionic acid) with a minor amount of N-acetyl-glufosinate and MP-acetic acid. (2-methylphosphinico-acetic acid) N-acetyl-glufosinate was readily de-acetylated to glufosinate with further metabolism to MP-propionic acid and MP-acetic acid.
