別買抗菌肥皂了。 用普通肥皂洗手足夠了。
FDA正在重新審核市麵上的抗菌肥皂。目前沒有科研證據證明所謂抗菌肥皂有抑製細菌傳播的作用，相反，主要成份三氯生(triclosan)可能促進耐藥菌和導致激素紊亂。2016年為止生產商如未能提交證據則禁止銷售。
CDC: Handwashing
In fact, there currently is no evidence that over-the-counter (OTC) antibacterial soap products are any more effective at preventing illness than washing with plain soap and water, says Colleen Rogers, Ph.D., a lead microbiologist at FDA.
Moreover, antibacterial soap products contain chemical ingredients, such as triclosan(三氯生) and triclocarban(三氯卡班), which may carry unnecessary risks given that their benefits are unproven.
"New data suggest that the risks associated with long-term, daily use of antibacterial soaps may outweigh the benefits," Rogers says. There are indications that certain ingredients in these soaps may contribute to bacterial resistance to antibiotics, and may have unanticipated hormonal effects that are of concern to FDA.
In light of these data, the agency issued a proposed rule on Dec. 16, 2013 that would require manufacturers to provide more substantial data to demonstrate the safety and effectiveness of antibacterial soaps. The proposed rule covers only those consumer antibacterial soaps and body washes that are used with water. It does not apply to hand sanitizers, hand wipes or antibacterial soaps that are used in health care settings such as hospitals.
