Some interesting info' on Dioxins:

Dioxin exposure causes a severe form of skin rash called chloracne, which results in small, pale yellow skin lesions that may last from weeks to years. Dioxins can cause short-term liver dysfunctions without any visible symptoms. These include changes in metabolism and enzymatic activity in the liver, which are similar to those resulting from the consumption of alcoholic beverages.
In animal studies, dioxins have caused nerve damage, birth defects, increased incidence of miscarriages and significant changes to the immune system. Studies have shown that reproductive, immune and nervous systems of the developing fetus and children are more sensitive and susceptible to dioxin toxicity. Exposure to large amounts of dioxins over a short period of time, or continuous low-level exposure over an extended period can cause cancer and other severe immune deficiency effects in animals; however, there is not sufficient information from human studies to establish these health effects in people. Although the U.S. Environmental Protection Agency has classified dioxins as a probable human carcinogen (cancer causing chemical); there is not sufficient evidence to prove that dioxins cause cancer from exposure to the low levels normally found in the environment. One dioxin, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is listed as a known human carcinogen and all the others as probable human carcinogens
