Many illnesses, miscarriages and animal deaths were attributed to the toxin. At the time, dioxin was called “the most toxic chemical synthesized by man.” Pretty scary stuff, and even scarier when you realize everyone eats a certain amount of dioxin every day. That’s because dioxins are found in meat and dairy products, and most other foods.
