Triclosan and Antibiotics resistance


Published on

Triclosan is added to many consumer goods such as cosmetics and detergents to kill microorganisms or inhibit their growth. It serves as disinfectant, preservative or antiseptic and is widely used in health care and animal husbandry.

There is concern that this widespread use of triclosan may lead to the emergence or proliferation of harmful bacteria that are resistant to both biocides and antibiotics.

In the light of current scientific evidence, can triclosan lead to antibiotic resistant bacteria?
