賣場購物使用的購物推車,在手把隱含許多不為人知的細菌,其中可能隱藏的細菌包括金黃色葡萄球菌與大腸桿菌,通常可輕易地藉由雞肉或啤酒溢出的液體、髒的尿布或帶有細菌的手傳播。在國外有許多賣場開始提供濕巾供客戶擦拭手推車,甚至已推動立法強制商家必須定期清洗購物推車。然而,提供大量的免洗濕巾可能會衍生另一種環境危害。雖然有許多的消毒、殺菌方法被發明,但對大面積、大空間的物體表面殺菌及空氣消毒,紫外線卻是首選的方法。

The handles of shopping carts can contain numerous bacteria, including Staphylococcus aureus and Escherichia coli. These can easily be transmitted through the liquid from raw chicken or beer, dirty diapers, or contaminated hands. Many shopping centers in various countries have begun providing customers with wet wipes to wipe shopping carts. Legislation has also been passed that requires purveyors to regularly clean shopping carts. However, mass distribution of one-use wet wipes may cause another form of environmental crisis. While there are many methods for sterilization and disinfection, ultraviolet light is the preferred method for large surfaces and air sterilization.
