解藻朊酸弧菌食物中毒1起流行病學調查

[摘要] 目的 對南通市某區1起因農村家宴引起的解藻朊酸弧菌食物中毒進行凋查分析，為該類食物中毒處理、防治提供參考。 方法 對該起食物中毒進行現場衛生學調查、流行病學凋查，對采集標本進行實驗室分離培養，通過統計學處理和病例對照分析，找出食物中毒原因并提出針對性防治對策。結果 綜合現場衛生學調查、流行病學調查、實驗室培養結果，確定該起食物中毒為1起解藻朊酸弧菌食物中毒，中毒原因可能為切菜刀、砧板生熟不分，食物加工不徹底。 結論 解藻朊酸弧菌與副溶血性弧菌生物特性相似，本地既往從未有相關報道，各地對解藻朊酸弧菌食物中毒報道也很少，衛生行政部門及疾控機構應加強對該類食物中毒的鑒別和研究，做好該類食物中毒的防治工作。
