FDA Investigates Antibacterial Soaps

Some companies have gone to great lengths to manufacture germ-killing products, like antibacterial soaps. In the United States, a federal agency recently called on the makers of such soaps to prove they are more effective than traditional soap and water. The Food and Drug Administration said the widespread use of antibacterial soap may be partly to blame for an increase in rising rates of drug-resistant bacteria.
Some evidence has suggested the products may even be harmful to your health.
The FDA has proposed that manufacturers be required to prove that antimicrobial soaps lower rates of disease more than other soaps. It also would require the companies to show how these cleansers do more good than harm.
