"WASHINGTON -- After more than 40 years of study, the U.S. government says it has found no evidence that common anti-bacterial soaps prevent the spread of germs, and regulators want the makers of Dawn, Dial and other household staples to prove that their products do not pose health risks to consumers."

"Scientists at the Food and Drug Administration announced Monday that they are revisiting the safety of triclosan and other sanitizing agents found in soap in countless kitchens and bathrooms. Recent studies suggest triclosan and similar substances can interfere with hormone levels in lab animals and spur the growth of drug-resistant bacteria.

The government's preliminary ruling lends new support to outside researchers who have long argued that the chemicals are, at best, ineffective and at worst, a threat to public health."
