Anti-Bacterial Soap No Better Than Plain Soap

eldavojohn writes to advise us to stop buying antibacterial soap, as it's no more effective than the regular stuff. And, using it introduces a risk of mutation of bacteria. From the article: "The team looked at 27 studies conducted between 1980 and 2006, and found that soaps containing triclosan within the range of concentrations commonly used in the community setting (0.1 to 0.45 percent wt./vol.) were no more effective than plain soaps. Triclosan is used in higher concentrations in hospitals and other clinical settings, and may be more effective at reducing illness and bacteria. Triclosan works by targeting a biochemical pathway in the bacteria that allows the bacteria to keep its cell wall intact. Because of the way triclosan kills the bacteria, mutations can happen at the targeted site... a mutation could mean that the triclosan can no longer get to the target site to kill the bacteria because the bacteria and the pathway have changed form."

Over the last few years it's become harder to find hand soap (at least the liquid type) that isn't antibacterial. The fad has pushed the added chemicals into all the major brands.

I've Been Saying This for Years

I've been saying for years that plain soap is good enough, and that it's bad for us as a species to use anti-bacterial soap. I have "body wash" in my soap dispenser in the bathroom, because all the "hand soap" is anti-bacterial these days.

Just goes to show that even an uninformed, loud-mouthed, opinionated jerk is right sometimes.
