Shopping cart handles are the most bacteria-infested items among some commonly used objects while doorknobs on public bathrooms are not as bad as might be expected，according to a survey conducted in South Korea.
The Korea Consumer Protection Board tested six items that are commonly handled by the public and ran tests for their bacteria content.
Shopping cart handles led the way with 1，100 colony forming units of bacteria per 10 sq cm（1.55 sq inches）followed by a mouse used on computers in Internet cafes，which had an average of 690 colony forming units.
“The reason that shopping cart handles had so much bacteria is because the area is larger than the others and people have more space to place their hands，”Kwon Young-il，an official at the consumer body，said by telephone.
Hand straps on buses were next with 380 units，followed by bathroom doorknobs at 340.
Rounding out the list were elevator buttons at 130 colony forming units and hand straps on subways at 86.
The report released this week said washing hands with soap removes almost all of the bacteria.（Agencies） |
韓國一項調查顯示：在人們經常使用的物品中，商店購物車扶手最容易滋生細菌，而公廁的門把拉手並不像人們想象得那樣可怕。
韓國消費者保護委員會檢驗了六項公眾經常觸摸的物品，並測試出這些物品的細菌附著量。
商店購物車扶手上的細菌最多，每10平方厘米（1.55平方英寸）就聚集著1100個菌落；其次是網吧的鼠標，每10平方厘米就有690個菌落。
韓國消費者保護委員會的一位官員權永逸在電話採訪中說：“購物車扶手上的細菌多，是因為購物車扶手比其它物體大，人手在上面的接觸面積比其它物體大。”
細菌附著量排在第二位的是公交車的拉手，每10平方厘米有380個菌落；其次是公廁的門把手，每10平方厘米附著菌落340個。
電梯按鈕上的菌落是130個，地鐵拉手上的菌落個數是86，這兩樣物體在細菌繁殖場排名中居後。
這份報告已于本週公佈，報告說用肥皂洗手幾乎可以除掉所有細菌。 |
