Abstract：
The coronavirus disease 2019 (COVID-19) pandemic is still spreading all over the world. Although China quickly brought the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) under control in 2020, sporadic outbreaks have recurred from time to time. Outbreaks since June 2020 have suggested that the imported cold food supply chain is a major cause for the recurrence and spread of COVID-19. Here we review recurrent outbreaks in China from June 2020 to March 2021, and we analyse the main causes for recurrence and transmission by the supply of imported cold food from port to fork. Contaminated cold food or food packaging material can transmit the virus through \'person-to-thing-to-person\', by contrast with the classical \'person-to-person\' pathway. We decribe safety precautions for the food system, operating environment and people along the cold chain logistics. Surface disinfection and nucleic acid inspection are needed in each stage of the logistics of imported cold food supply.
摘要：
2019年冠状病毒病(COVID-19)大流行仍在世界各地蔓延。尽管中国在2020年迅速控制了严重急性呼吸道综合症冠状病毒2（SARS-CoV-2），但仍不时发生零星疫情。自2020年6月以来的疫情表明，进口冷食供应链是COVID-19复发和传播的主要原因。在此，我们回顾了2020年6月至2021年3月中国的反复疫情，并分析了从港口到餐桌的进口冷食供应导致复发和传播的主要原因。受污染的冷食或食品包装材料可以通过“人对人”传播病毒，与经典的“人对人”途径相反。我们为食品系统提供安全预防措施，冷链物流沿线的运营环境和人员。进口冷食供应物流的每个阶段都需要表面消毒和核酸检测。
