What does the science say?
An earlier literature review of studies assessing GMO safety came to a similar contradictory finding. While there were just as many studies claiming that GMOs are safe for consumption as not, the ones that found GMOs safe were, for the majority, funded by biotechnology companies responsible for bringing those GMOs to market.
What does this mean for me?
While the scientific evidence does not decisively conclude that GMOs are unsafe, they are not naturally occurring (by definition) and there is evidence for their harm both in consumption and for the environment. The truth is that many of the GMOs that are available today are regulated by the companies that have developed them and the governmental frameworks for regulation are weak. Until there is open, credible knowledge about the long-term effects of each individual GMO that has been created, there can be no blanket statement made on GMOs' impact on health, the environment and society. It looks like this will not be happening any time soon, so we have made the decision to use no genetically modified organisms.
