Survey on Bacillus cereus, Staphylococcus aureus and Salmonella spp. in Dairy Products

本計畫自民國八十七年七月至八十八年三月間，由台灣北部地區抽購市售乳品100件，含鮮乳16件、保久鮮乳10件、調味乳14件、保久調味乳20件、乳粉10件及乾酪30件，進行仙人掌桿菌、金黃色葡萄球菌、沙門氏桿菌及其他衛生指標菌之檢驗，結果發現全部乳品在仙人掌桿菌、金黃色葡萄球菌及沙門氏桿菌之檢驗皆合格。在衛生指標菌中生菌數及大腸桿菌之檢驗皆合格，但大腸桿菌群之檢驗，僅有1件調味乳大腸桿菌群數為93MPN/mL超出我國衛生標準10MPN/mL為不合格，其他乳品在大腸桿菌群之檢驗皆合格，另所有乳品之標示亦皆符合規定。本調查係本局之比較檢驗，曾於八十九年八月十九日發佈新聞在案。

From July 1998 to March 1999, we purchased 100 dairy product samples from markets in northern Taiwan area. Included 16 pasteurized milk, 10 sterilized milk, 14 pasteurized flavored milk, 20 flavored milk, 10 milk powder samples and 30 cheese samples were purchased to detect Bacillus cereus, Staphylococcus aureus, Salmonella spp.. Routine analysis was also performed on these samples. The results demonstrated that all of the samples met the hygiene standard requirements in the detection of Bacillus cereus, Staphylococcus aureus, Salmonella spp. Though one sample of pasteurized milk was detected with 10CFU/mL of Bacillus cereus, it met the hygiene standard requirements, which Bacillus cereus should be below 100CFU/mL.In routine analysis of total plate count and Escherichia coli, all samples met the hygiene standard requirements. On the detection of coliform, only one of the flavored milk samples did not meet the hygiene standard requirements (＜10MPN/mL), which contained 93MPN/mL coliform bacteria. Other dairy products met the hygiene standard requirements in the detection of coliform.However, 50CFU/g of Bacillus licheniformis was isolated from one cheese sample, and 5CFU/mL of Staphylococcus auricularis was isolated from one pasteurized milk sample.
