中西式速食餐飲店微生物之調查

MICROBIOLOGICAL STUDY ON FAST FOODS

自七十五年十月至七十六年五月底止，分三季（七十五年十～十一月、七十六年一～三月、五月）自本省北、中、南、東四區定點抽樣調查713件市售「中西式速食」檢體。其中中式速食計116件，西式速食計597件，其檢驗結果為：檢出金黃色葡萄球菌28件（3.9%），葡萄狀球菌165件（23.1%），大腸桿菌29件（4.1%），沙門氏桿菌2件（0.3%）。總陽件數為179件（25.1%）。三季之檢出件數分別為51件、65件、63件，其檢出率分別為22.3%、25.5%、27.4%。以卡方分析顯示檢出率具季節差異性。由檢驗結果得知：葡萄狀球菌分佈最普遍，而沙門氏桿菌之污染最少。依卡方分析：中式與西式速食之檢出率並無顯著差異；依變方分析，各檢體間之檢出率在全省各區間並無顯著差異；但中式速食中以涼拌類（62.5%）被細菌污染最嚴重；西式速食以沙拉（48.2%）被細菌污染最嚴重。

From Oct 1986 to May 1987, 713 samples of marketed fast foods (Chinese style and American style) were collected from the fast food stores of four areas in Taiwan, tested for the microbial survey. 116 samples were Chinese style, and 597 samples were American style. The results were: Staphylococcus aureus was detected 3.9% (28 samples), Staphylococci 23.1% (165 samples), E. coli 4.1% (29 samples), Salmonella spp. 0.3% (2 samples). Above all, 25.1% of the samples failed to meet the Food Hygienic Standard. During the autumn, winter, and spring seasons, the detection frequencies were 22.3% 25.5% and 27.4%. With the analysis of variance, the detection frequency showed seasoal vairance, and there is no positive stastistical correlation occurred between the detection frequency and Chinese/ Western style of fast food.
