免洗筷之衛生調查

AN INVESTIGATION ON THE SANITATION OF THE DISPOSABLE CHOPSTICKS

近年來，免洗筷已被消費大眾廣泛使用，免洗筷與重複使用筷之微生物污染調查比較顯示免洗筷比重複使用筷乾淨得多。目前市面上免洗筷可分為雙生筷與小黃筷， 其中小黃筷仍有被重複使用之虞，故本調查參照中國國家樣準針對雙生筷及小黃筷進行微生物檢驗，期比較此二種免洗筷之品質差異，並對重複使用竹筷進行微物檢驗，以茲比較免洗與重複筷子間之差異。本次調查以台北市及北部地區五縣市為主，抽驗各大飯店、餐館、小吃店等所使用之免洗筷，共計210件，其中小黃筷92件，雙生筷118件。其檢驗結果如表一大腸桿菌屬細菌均未檢出，葡萄狀球菌僅小黃筷檢出2件，至於每雙生菌數 0-30 CFU 之百分比，雙生筷（58.5%）略高於小黃筷（52.2%） ，300 CFU 以上之百分比，雙生筷皆低於小黃筷，兩者最高菌量均為103- 104 CFU/雙。另在抽樣之52件重複使用竹筷中，大腸桿菌屬細菌檢出率為32.7%，其生菌含量則有高達107-108CUF/雙者。

From Oct. 1986 to Feb 1987, 210 samples (including 118 twin style chopstickes and were examinated for total viable count, coliform bacteria and Staphylococcus spp. The results showed that all samples were coliform-negative; 2 samples of small round style chopstickes were staphylococci-positive. The percentage of speciemens whose total viable count were between zero and thirthy per pair were 58.5% and 52.2% for twin style chopstickes and small round style chopstickes, respectively. The highest count of both were 103～104CFU/pair. The positive percentage of coliform bacteria in anether 52 pairs of reusable was 32.7%, the total viable count was up to 108～109CFU/pair.
