Cleaning Up The Soap Industry

The FDA has admitted that antibacterial soap is probably no better than regular soap – and may even be bad for you:

In a draft rule that will be published Tuesday in the Federal Register, the agency calls for manufacturers of consumer antibacterial products to begin providing data that shows the ingredients are both safe for daily use, and also more effective than plain soap and water. Deep in the 137-page rule, it also raises the issue that’s most interesting to me: whether the routine use of these products causes bacteria to develop resistance against the active ingredients, and against antibiotics as an unintended side effect.

Kiera Butler relays scientists’ concerns over triclosan, the most common ingredient in antibacterial products:

[T]here is strong evidence that anti-bacterial soaps contribute to antibiotic resistance. In 2004, a team of University of Michigan researchers found that exposing bacteria to triclosan increased activity in cellular pumps that the bugs use to eliminate foreign substances. These overactive excretory systems “could act to pump out other antibiotics, as well,” says Stuart Levy, one of the study’s authors and a leading researcher on antibiotic resistance at the Tufts University School of Medicine. That’s a problem, since troublesome bacteria like streptococcus, staphylococcus, and pneumonia are already evolving defenses against our best weapons. Worse, there aren’t enough new drugs in the production pipeline. Over the past 15 years, the FDA has approved just 15 newantibiotics—in the preceding 15 years, it approved 40. The World Health Organization now views antibiotic resistance as “a threat to global health security.” And while triclosan’s contribution to the problem hasn’t been adequately studied, Levy believes it could be “significant.”
