凍不死! 新冠病毒「負80度下」21天仍活躍

新冠病毒在零下80度C能活多久？答案是「至少21天」，新加坡一項研究把病毒和肉品一起放在4度、-20度和-80度C實驗，經過21天，三種溫度下病毒量都沒改變，同樣具有傳染性，這項研究等於證明冷凍食品會夾帶病毒，因此就算是鮭魚，醫師也建議熟食，另外摸過冷凍包裝的手，務必清潔！

此為新加坡杜克大學8月18日發表於「bioRxiv」平台的研究，但此僅為論文預印本，尚未經同儕審查。

1. 該研究將新冠病毒添加至魚、雞、豬肉立方體中，發現存放在4°C，–20°C和–80°C的環境下21天，病毒濃度都沒有顯著變化，且仍有感染力。研究認為：「國際食品市場龐大，有時甚至會發生非常不可能的事件」，因此消費者應增加預防措施，保持良好手部衛生並定期清潔廚房器具、檯面，接觸未煮過的產品後應洗手，並確保食物煮熟。

2. 杜克大學醫學院新興傳染病計劃副主任Ooi Eng Eong教授說，病毒確實可能通過處理不當的食物傳播，但風險可能很小。目前美國和世衛也均表示，尚沒有證據顯示冷凍食物可傳播新冠病毒。
