Roundup, as many of you know, is a commonly used weedkiller linked to cancer, and traces of the chemical are now appearing in more than 80% of urine samples from kids and adults in the U.S., according to a new study. Alexis Temkin, toxicologist at the Environmental Working Group, said in a statement: “Glyphosate is the most widely used herbicide in the country, yet until now we had very little data on exposure. Children in the U.S. are regularly exposed to this cancer-causing weedkiller through the food they eat virtually every day.”
