Fact of Myth? Antibacterial Soaps can help create resistant strains.
Answer: Possibly a Fact
The antibacterial triclosan is rinsed off before it can do all its work and then enters the water supply and resistant strains of bacteria have been created in labs using triclosan, although it remains to be seen if it will happen in the natural environment.
Accumulation of triclosan in the environment or chronic exposure to it on a long-term basis, especially for children, may have a long-term risk that we will not discover until later on.
And, studies show that antibacterial soap doesn't do enough to justify its use; regular soap rids germs from hands just as effectively as antibacterial soaps.
