Evaluation of Emerging Pathogens from New Unidentified Risk Diets in Taiwan

107年度所執行產品後市場監測計畫，係針對新式不明風險飲食進行監測研究，共計抽驗以生食為主的不明風險飲食60件及販賣機商品40件，檢驗項目包含衛生指標菌（生菌數、大腸桿菌群及大腸桿菌）、病原菌（金黃色葡萄球菌、病原性大腸桿菌、仙人掌桿菌、單核球增多性李斯特菌及沙門氏桿菌），另水產品加驗腸炎弧菌、霍亂弧菌及創傷弧菌。檢驗結果顯示：衛生指標菌不符合衛生標準者共9件，其中販賣機茶飲料5件、酸肉2件、生食牛肉及月見冰各1件，不合格率為9％；另檢出病原菌者共9件，其中5件（酸辣生蝦及生蛋拌飯各2件、生乳酪1件）檢出仙人掌桿菌、2件酸辣生蝦檢出腸炎弧菌、1件生食牛肉檢出金黃色葡萄球菌、1件酸肉同時檢出沙門氏桿菌及金黃色葡萄球菌，上述檢驗結果均已函復轄區衛生局。本年度新式不明風險飲食潛藏病原之評估研究成果可瞭解市售新式飲食之衛生安全狀況及食因性病原菌污染情形，可作為輔導管理之參考，並督導業者改善及提昇產品品質。

This study focused on post-market survey of new unidentified risk diets. A total of 60 samples of raw ready-to-eat diets and 40 samples of vending machine products were tested for monitoring microbiology hygienic quality in 2018. In addition to hygiene indicators - aerobic plate count, coliform, and Escherichia coli - pathogenic microorganisms, such as Staphylococcus aureus, pathogenic E. coli, Bacillus cereus, Listeria monocytogenes, and Salmonella spp., were also examined in each sample. Moreover, marine products were additionally tested for Vibrio parahaemolyticus, Vibrio cholerae and Vibrio vulnificus. The results showed that there were 9 samples (9%) that failed to meet the sanitation standards, including 5 tea drinks from vending machine, 2 Naem (pork sausage in Thai cuisine), 1 ready-to-eat fresh beef, and 1 shaved ice with egg yolk and condensed milk. Among the 9 pathogen positive samples, 5 samples (including 2 ready-to-eat hot and sour raw shrimps, 2 steam rice with raw egg mixtures, and 1 raw cheese) were detected with Bacillus cereus; 2 samples of ready-to-eat hot and sour raw shrimps were detected with Vibrio parahaemolyticus; 1 sample of ready-to-eat fresh beef was detected with Staphylococcus aureus; and 1 Naem sample was found with both Salmonella and Staphylococcus aureus. All these above results had been forwarded to the local health authorities. Consequently, this evaluation not only revealed the condition of microbial quality in new unidentified risk diets but also provided specific consultations for the government and supervised manufacturers to improve and enhance product quality.
