新冠疫情下食品安全检测的重要性

自2019年12月以来,由严重急性呼吸综合征冠状病毒2(SARS-CoV-2)感染引发的2019冠状病毒病(COVID-19)疫情已在全世界超200个国家流行。有研究指出,COVID-19疫情在武汉的初次爆发和2020年6月北京市的疫情反弹均可能与当地的批发市场有关。尽管目前尚无确切证据表明SARS-CoV-2的输入来自于批发市场所售食品,但对食品中潜在的SARS-CoV-2进行检测,将有助于防止病毒的输入和扩散,可大幅降低批发市场食品中潜在的疫情传播风险。文章就SARS-CoV-2的潜在宿主、检测食品中SARS-CoV-2所存在的困难及相关检测技术展开探讨,以期为食品的新冠病毒检测方法的建立提供参考。

Since December 2019, the Corona Virus Disease 2019(COVID-19) caused by Severe Acute Respiratory Syndrome Coronavirus 2(SARS-CoV-2) infection has been prevalent in more than 200 countries. Some studies have pointed out that the initial outbreak of COVID-19 in Wuhan and its rebound in Beijing in June 2020 might have been related to the local wholesale market.Although there is no definite evidence that the import of SARS-CoV-2 came from the food sold in the wholesale market, the detection of potential SARS-CoV-2 in food will help prevent the import and spread of the virus and may greatly reduce the potential spread risk of the epidemic in the food in the wholesale market. This paper discusses the potential host of SARS-CoV-2, the difficulties in detecting SARS-CoV-2 in food, and related detection technologies, so as to provide reference for the establishment of COVID-19 detection methods for food.
