Greater uses of antibiotic chemicals are causing random mutations in bacteria that allow them to survive exposure.
Many liquid soaps labeled antibacterial contain triclosan, an ingredient of concern to many environmental, academic and regulatory groups. Animal studies have shown that triclosan alters the way some hormones work in the body and raises potential concerns for the effects of use in humans.
Young people who are overexposed to antibacterial soaps containing triclosan may suffer more allergies, and exposure to higher levels of Bisphenol A among adults may negatively influence the immune system, a new study suggests. Antimicrobials are chemicals added to products with the intention of killing or inhibiting the growth of microbes.
