Antibacterial Resistance from Soap: Hazard or Hype?

Aiello et al. (2005) examined whether household use of antibacterial cleaning and hygiene products is an emerging risk factor for the carriage of antimicrobial drug-resistant bacteria on the hands of household members. Over 200 households were randomized to the use of antibacterial or non-antibacterial cleaning and hygiene products for one year, including the use of a handwashing soap containing 0.2 percent triclosan. The authors conclude that the use of antibacterial products did not lead to a significant increase in antimicrobial drug resistance, nor was there an effect on the bacterial susceptibility of triclosan.

The conclusions from a significant body of research strongly suggest that antibiotic resistant and antibiotic sensitive bacteria are equally sensitive to the in-use concentrations of antimicrobials. There is also evidence, in real world situations, that using antimicrobials such as antibacterial hand soaps does not select for antibiotic resistant bacteria. These products provide a public health benefit, and their use should not be discouraged.
