抽購臺灣南部地區傳統市場及超級市場所販售有品牌且包裝完整之豆腐、豆花、豆漿等黃豆加工品及果凍檢體共計150件。均依據中國國家標準檢驗方法，進行仙人掌桿菌及大腸桿菌之檢驗。檢驗結果顯示：仙人掌桿菌之檢出率為4.67% （7/150），其中豆腐7.69% （2/26）、豆漿8.33% （1/12）、果凍3.96% （4/101）、豆花則未檢出（0/11）；含菌數範圍為1.1～24 MPN/g，均符合我國現行衛生標準之每公克應在100個以下。大腸桿菌則僅1件豆漿中有檢出，不合格率0.67% （1/150）。

To assess the degree to which Badllus cereus and Escherichia coli may contaminate Soy-bean and jelly products, 150 samples were randomly collected from traditional and commercial super-markets, in the southern region of Taiwan. R cereus was detected in 4.67% of the total samples collected (7/150); 7.69% of 26 tofu samples, 8.33% of 12 soy milk samples, 3.96% of 101 jelly samples, 0% of 11 soy yogurt samples. E. coli was detected in only one soy milk sample (0.67% of 150 total samples).
