WASHINGTON (AP) — 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.
“The FDA is finally making a judgment call here and asking industry to show us that these products are better than soap and water, and the data don’t substantiate that,” said Stuart Levy of the Tufts University School of Medicine.
While the rule only applies to personal hygiene products, it has implications for a broader $1 billion industry that includes thousands of anti-bacterial products, including kitchen knives, toys, pacifiers and toothpaste.
