104年度綠島地區供食生蠔造成食品中毒事件調查與處置

Investigation and Administrative Action on Foodborne Disease Outbreaks Caused by Consuming Raw Oyster in Ludao Township in 2015

104年6月25日至30日間食品藥物管理署（以下稱食藥署）陸續接獲臺東縣衛生局通報轄內發生7起疑似食品中毒案，計102名遊客出現噁心、嘔吐、腹痛及腹瀉等中毒症狀，食藥署初步判斷數起疑似食品中毒案非單獨偶發事件，即建議臺東縣衛生局進行食品中毒調查，後依據調查結果，於6月30日建議臺東縣衛生局命轄內綠島鄉餐廳暫時停止供應生蠔，且自7月1日起未有新增通報病例。本案食藥署針對可疑食品及用餐環境進行食品中病原菌及病毒檢驗，其中2件生蠔檢體皆檢出諾羅病毒，為避免有衛生安全疑慮之生蠔繼續危害消費者健康，由地方政府衛生局命業者回收有安全疑慮之生蠔產品並予以封存。另疾病管制署取得患者檢體共17件，10件驗出諾羅病毒陽性，經流行病學調查結果，食用生蠔與中毒事件有顯著統計相關。綜合本案檢驗及調查結果，顯示封存之生蠔已受到諾羅病毒污染，臺東縣衛生局爰依食品衛生管理法第15條1項4款規定：「染有病原性生物，或經流行病學調查認定屬造成食品中毒之病因」，對供應問題生蠔餐食業者依同法44條1項2款處以新臺幣10萬元罰鍰，併依同法第52條，問題生蠔予以沒入銷毀。

Food and Drug Administration was informed by Taitung Health Bureau of 7 cases of suspected foodborne disease in Taitung County in June 2015. A total of 102 consumers had symptoms of nausea, vomiting, and diarrhea with abdominal cramps. The restaurants in Ludao Township were asked to stop the supply of raw oyster since 1^(st) July, then no further informed cases. Forty three samples including 2 oysters, other foods and 22 environmental samples were screened for pathogenic bacteria and enteric viruses. Two oyster samples were found contaminated with norovirus. Seventeen human specimens were also collected and ten were positive for norovirus. According to epidemiological investigation, the correlation between foodborne disease outbreaks and oyster is significant. The investigation concluded that the oyster contaminated by norovirus was the etiological agent that should be destroyed according to the Act Governing Food Sanitation.
