85% of All Food in U.S. Now Contaminated: Toxic Pesticides Also Found in Drinking WaterModern agricultural practices have led to ever-increasing amounts of chemicals being used on our food, and whether we're talking about pesticides, herbicides or fungicides, most have deleterious effects on health. According to the latest report on pesticide residues in food by the U.S. Department of Agriculture (USDA), a mere 15 percent of all the food samples tested in 2015 were free from pesticide residues. In 2014, over 41 percent of samples had no detectable pesticide residues on them. That just goes to show how quickly our food is being poisoned. At that trajectory, we may eventually find out none of the non-organic food sold in 2016 or 2017 was pesticide-free. Recent news has highlighted a number of problems associated with this out-of-control use of agricultural chemicals, starting with atrazine.
