For example, in the US, a tampon was causing toxic shock syndrome in some women. Production was immediately halted, but the cause of illness was only found ten years later. The product was designed to be super-absorbent and longlasting. But, if the tampon had already absorbed blood, at temperatures of 37 ℃ it became a hotbed for staphylococcus, leading to toxic shock.
像美國某一廠牌衛生棉條導致婦女中毒、休克事件，在事件發生、衛生棉停產十年後才找出致病原因：是由於該廠牌衛生棉條強調吸水性超強，可以持久使用，然而沾血的棉花在攝氏三十七度的「保溫」下，成了培養細菌的溫床，使用者中毒、休克就是葡萄球菌導致的。
