“Over the past ten years a large body of peer-reviewed science has raised concerns that fluoride may present unreasonable health risks, particularly among children,
at levels routinely added to tap water in American cities.”
— Environmental Working Group, July 2005

Numerous studies have shown serious, adverse health consequences from fluoride ingestion.  Symptoms of fluoride poisoning found in industrial workers have included osteosclerosis, ossifications of ligamentous attachments, sinus trouble, perforation of the nasal septum, chest pains, coughs, thyroid disorders, anemia, dizziness, weakness and nausea.

According to the U.S. Department of Agriculture, fluorosis symptoms in domestic animals include “dental mottling, respiratory distress, stiffness in knees or elbows or both.”  There have also been several reported cases of livestock death. The same USDA handbook points out that human beings are “much more sensitive than domestic animals to F [fluoride] intoxication.”
