进口车厘子、奶枣,啤酒、雪糕等频繁检出新冠病毒,还能安心吃吗? 张文宏:放心吃!

接二连三的食物外包装被检出新冠病毒核酸阳性,确实让人恐慌——

接二连三的食物外包装被检出新冠病毒核酸阳性,确实让人恐慌——进口食品还能放心吃吗?病毒从食物传染给人的概率有多大?

2020.6.20 当地相关部门抽检时从切割进口三文鱼的案板中检测到了冠病病毒,新发地市场的牛羊肉、猪肉、蔬菜、水果及其相关设施等抽检中暂未发现冠病病毒。见:北京连续新发新冠病例,三文鱼传播新冠?

2020.10.17,国家疾控中心对青岛疫情溯源调查中,从进口冷冻鳕鱼外包装中检测分离到活病毒,正式确认“冷链运输”是新冠传播途径。

2021.01.14 天津津南区在送检的雪糕样本中,发现3份雪糕新冠病毒核酸检测样本检测结果呈阳性。次日,用于生产雪糕的乌克兰进口原料乳清粉3份样本,新冠病毒核酸检测呈阳性。

2021.01.19 山东枣庄市从一企业用于生产奶枣的进口乳清粉仓库现场环境核酸检测结果阳性。多地通报涉疫奶枣流入情况,烟台流入奶枣产品2管标本新冠病毒核酸检测结果阳性;贵州6地奶枣样品中检出阳性;浙江丽水已测出9份阳性产品。

2021.01.21 广东省中山市一批来自巴西冻鸡翅中外包装核酸检测结果呈阳性。见:深圳龙岗1份进口冻鸡翅表面检出“新冠”!

2021.01.22 江苏省无锡市梁溪区通报,一份进口车厘子内表面核酸检测阳性。见:水果表面新冠病毒阳性,放心吃要注意两个关键要点

2021.01.23 浙江省舟山市对某企业进口阿根廷冻红虾检测中,发现集装箱内壁及货物外包装新冠病毒核酸检测呈阳性。

2021.01.24 天津市宁河区发现一批美国进口啤酒整托外包装样本检测结果呈阳性。

进口食品还能放心吃吗?病毒从食物传染给人的概率有多大?我们看看专家怎么说——

中国疾控中心副主任冯子健:核酸阳性并不意味着一定有传染性!

“要看它污染的量,另外污染的病毒是不是有活性。从我们了解的情况,无锡此份进口车厘子检到的核酸阳性,病毒的载量很低,对消费者不会造成太大的感染风险。”

冯子健表示,到现在为止,虽然我们不断发现各种进口货品检出阳性,但是并没有发现普通的消费者被这种进口商品所污染的病毒感染。

张文宏说买进口商品被感染概率低于空难:至今一例都没有!张文宏说:“到目前为止,中国消费了无数的海鲜,买了无数的东西,我只是看概率,因为买了一件国外进来的东西而被感染,到现在为止一例都没有发生。当这个概率比空难还低的时候,你自己决定。”

上海新冠疫情防控工作领导小组医疗救治专家组组长张文宏教授认为:货物是怎么传染,就涉及到病毒在外残留的时间,在环境里面残留的时间会长一点,物体表面空气当中会不会形成气溶胶,在冬天和夏天有什么区别,有没有紫外线的照射情况下面又是怎么样。我是临床救治专家组的组长,也是防控专家组的专家。救治方面是以救治病人为主。在防控方面上,我们要想办法追溯到这一个疾病的上游,如果找不到原因的话,这件事情一定会再发生。

从2020年初疫情开始以来,“人传人”的防控上一直目标明确,减少接触,做好防护,在实践中逐步建立了常态化防控体系。但“物传人”则一直处于目标不明的探索阶段,需要根据全球疫情变化,在不停止货物流通的情况下,预防因进口货物导致的疫情传播。

张文宏表示:新冠病毒的物传人现象不会改变国家对疫情总体的把控能力。目前有冷链传人情况,但基本都是市场、物流等第一接触点的人员感染,没有因吃冻肉、海鲜而感染的病例,不必过于恐慌。我们应保持警惕,注意人群聚集时的传染病防控。

但是提醒一句:勤洗手!

事实上,梅斯医学观察到,早在去年就有很多研究回答了这个问题。病毒在人体外存活时间是相对较短的,在正常的物体表面,一般存活不会超过24小时(远远超过进口需要的时间),虽然超过24小时仍然能检测出病毒核酸,但是早已不具备传染性。虽然在冷冻状态下,病毒可以存活很长时间,但是,冷冻食物不容易形成气溶胶传播,而且冷冻食物,一般都需要经过烹调处理,病毒极易被杀死的。详细见:病毒在不同物体表面能存活多久? 谁是最佳COVID-19新型冠状病毒在纸板箱表面可存活24小时,塑料和不锈钢表面则长达两到三天
