New multi-toxin GMOs that produce their own poison carry ‘serious health and environmental risks’ scientific review finds

New strains of GM crops that produce pesticides in their own tissues are being approved without rigorous safety testing, even though they may carry “serious health and environmental risks,” according to a research review conducted by scientists from the Swiss Federal Institute of Technology and the German Federal Agency for Nature Conservation, and published in the journal Frontiers in Environmental Science on November 9.
The crops in question are engineered to carry pesticide-producing genes from the bacterial species Bacillus thuringiensis (Bt). In recent years, companies have increasingly turned to crossbreeding different varieties of Bt crops, producing crops that now carry numerous different strains of Bt toxin at once. These “stacked-trait” crops are being approved for planting and sale, based on several false assertions made by the genetically modified (GM) crop industry, the study found.
Hiding toxic effects
One such assertion is that each individual Bt toxin affects only a small number of insect pests, and has no effects on other species such as beneficial insect predators (“non-target” species). But the researchers found numerous studies showing the opposite to be true.
