How are humans exposed to dioxins?
Dioxins are also found in animal tissues, including humans. Most of the dioxins found in humans come from food. Diet is estimated to account for about 95 percent of dioxin exposure in the general community. For example, traces of dioxins in the soil are swallowed with grass when cattle graze, and passed on to humans in dairy products and meat. Dioxins accumulate in fats and oils because they are more soluble in fats and oils than in water.
