Genetically modified crops have been used to feed livestock since the mid 1990’s, and now it accounts for around 90% if all the animal feed in the United States. Ever since its introduction, there has been massive controversy surrounding the safety of this practice.
Unfortunately, the conversation has been polluted by anecdotal evidence and “studies” in journals that are not subjected to peer review which claim that genetically modified food causes numerous physical ailments, even cancer.

The analysis took into account over 100 billion animals collectively eating trillion of genetically modified meals between 1983 and 2011, and it isn’t the first of its kind. Alessandro Nicolia of the University of Perugia in Italy published a review last fall of 1,783 papers over a 10 year period that sought to understand the risk of genetically modified crops on the environment. Ultimately, there was no evidence showing genetically modified food poses a significant risk.
