日常生活工作中,很多人爱用“吸管杯”喝水,尤其是办公室里用吸管杯随时吸一口,既方便还能防止洒漏。不少人还觉得,用吸管杯喝水,不知不觉能喝进更多水。
不久前,家住北京朝阳的张女士(化名)发现,孩子腹泻不止并伴有咳嗽,排查发现根源竟是孩子每天都在使用的吸管水杯。尽管每天都会冲洗,但吸管内与水杯接口处布满霉菌。

A Beijing child developed persistent diarrhea and a cough after mold was found inside a reusable straw cup, prompting doctors to warn of the hidden hygiene risks posed by poorly cleaned drinkware.
The child's family said the cup had been rinsed daily, but mold was later discovered inside the straw and around its connection to the cup.
爱用吸管杯喝水的人
可能天天在喝细菌“洗澡水”
很多人觉得,自己只拿吸管杯装白开水喝,又不装饮料,能脏到哪去?可现实是,哪怕只喝白开水,吸管杯依然容易“藏污纳垢”。
不少网友都表示自己使用的吸管水杯也存在这类问题,尤其是进入夏季,情况更加严重。

“吸管杯的清洁盲区,远比我们想象得多。”华中科技大学同济医学院附属协和医院感染科副主任赵雷接受采访时指出,吸管杯和普通敞口杯最大的区别有两点:
一是结构复杂,吸管内部细长、有弯折,咬嘴、密封圈、重力球等部件形成大量死角;
二是长期潮湿、难以彻底干燥,这恰好是微生物繁殖的“最佳条件”。
另外,我们每次喝水,口腔里的唾液、食物残渣、细菌都会顺着吸管“回流”到杯内,日积月累,在管壁上形成一层滑腻的生物膜。这就是杯子用久了会发黏、有异味的真正“元凶”。再加上夏天闷热潮湿,杯子内部长期处于“温暖湿润”的密闭环境,简直是微生物繁殖的“理想泳池”。
Doctors said straw cups are prone to trapping moisture and bacteria because of their complex design. Saliva and food residue can also flow back into the cup through the straw, forming a biofilm and creating favorable conditions for microbial growth, especially in hot and humid weather.
赵雷提醒,吸管内壁常见的致病性微生物包括:
大肠杆菌、金黄色葡萄球菌等肠道致病菌:随饮水进入消化道,可能引起急性胃肠炎,出现腹痛、腹泻、恶心等症状;
曲霉菌、青霉菌等霉菌:释放的孢子会随水雾或气流吸入呼吸道,诱发慢性咳嗽、打喷嚏、鼻塞甚至呼吸困难。
医生提醒
这4类饮品最易在杯子中滋生细菌
除了白开水以外,不少人习惯用吸管杯冲泡各种饮品,这会加剧水杯藏污纳垢的风险。赵雷医生提醒,这4类饮品最容易在杯中残留变质:
▌蛋白粉和奶制品:蛋白质在常温下极易附着在管壁上,凝固后很难冲掉,细菌繁殖速度快。
▌奶茶、含糖饮料:高糖分是微生物的“豪华大餐”,一旦残留,细菌会大量繁殖。
▌柠檬水、果汁:果酸和果糖残留不仅养菌,酸性成分还会加速硅胶密封圈老化,缩短使用寿命。
▌咖啡:咖啡因和油脂容易附着在吸管内壁,清洗不彻底就会产生异味,同时滋生细菌。
Medical experts warned that contaminated straw cups may harbor bacteria and mold that can cause gastrointestinal illness or respiratory symptoms. Sugary drinks, dairy products, fruit juice and coffee are more likely to leave residue that promotes microbial growth.
爱用吸管杯的人注意
每周深度清洁记住5步
使用吸管杯,最好做到“即用即洗”,每周至少深度消毒一次。具体操作可以按以下5步来:
① 拆:把吸管、咬嘴、硅胶密封圈、重力球等所有配件全部拆开,不留死角。
② 刷:用专用细长吸管刷反复刷洗,重点处理U形弯折处,确保刷毛覆盖内壁所有区域。
③ 泡:对付顽固污渍,可用10%白醋温水或食用小苏打溶液浸泡20-30分钟,软化生物膜后再刷。
④ 消:硅胶配件可用沸水煮3-5分钟消毒;塑料和杯体部件用40℃左右温水配合食品级清洁剂清洗,避免高温导致变形老化。
⑤ 晾:洗净后把所有配件倒扣在通风处彻底晾干,再重新组装。吸管和硅胶密封圈建议每3-6个月更换一次,一旦出现异味或变色,立刻淘汰。
It is recommended to wash straw cups immediately after each use and give them a thorough cleaning at least once a week. All removable parts should be taken apart, scrubbed with a dedicated straw brush, disinfected as appropriate for the material, and allowed to dry completely before reassembly.
It is also advised to replace straws and silicone seals every three to six months, or sooner if they develop an odor or become discolored.
