Is the supposed safety advantage of GMO crops over conventional chemical pesticides a mirage?
According to biotech lore, the Bt pesticides introduced into many GMO food crops are natural proteins whose toxic activity extends only to narrow groups of insect species. Therefore, says the industry, these pesticides can all be safely eaten, e.g. by humans.
This is not the interpretation we arrived at after our analysis of the documents accompanying the commercial approval of 23 typical Bt-containing GMO crops, however (see Latham et al., 2017, just published in the journal Biotechnology and Genetic Engineering Reviews). More
