Are you helping to poison your children every time you give them a hamburger, a grill cheese sandwich, or a glass of milk?  Well according o many liberal activists like Lois Gibbs and the Citizens Clearinghouse for Hazardous Waste, the answer is yes because of the dioxin found in these foods.  But recent scientific reports indicate these charges are nothing but toxic hysteria.  One report of the National Cancer Institute found that at its present levels, dioxin poses no threat whatsoever to public health, while another showed that the average adult is only exposed to about 2 parts per quadrillion each day.  And just how small a dioxin exposure is that?  Well how about the equivalent of two human hairs out of all the hair on all the heads in all the world.
