The COVID-19 pandemic has generated a new era in the world, also in the food safety. Up to now, there is no evidence to suggest that people can infect COVID-19 via food contaminated by SARS-CoV-2. Here, we analyzed the results of regular SARS-CoV-2 nucleic acid testing of considerable cold-chain food practitioners, cold-chain food surfaces, and their internal or external packaging as well as their associated environments, aiming to explore the risk of cold-chain food being contaminated by SARS-CoV-2 and the probability of people infecting COVID-19 through contaminated cold-chain food in the context of COVID-19 epidemic. This study found that only two batches of cold-chain food were contaminated by SARS-CoV-2, none of the cold-chain food handler were infected due to effective regulatory measures for cold-chain food. Therefore, effective supervision and preventive methods could effectively reduce the transmission risk of SARS-CoV-2 on cold-chain food.

COVID-19 大流行在世界上创造了一个新时代，在食品安全领域也是如此。到目前为止，没有证据表明人们可以通过被 SARS-CoV-2 污染的食物感染 COVID-19。在这里，我们分析了大量冷链食品从业人员、冷链食品表面及其内外包装及其相关环境的常规 SARS-CoV-2 核酸检测结果，旨在探索感冒的风险。 - 链食品被 SARS-CoV-2 污染，以及在 COVID-19 流行情况下人们通过受污染的冷链食品感染 COVID-19 的可能性。本研究发现，只有两批冷链食品被SARS-CoV-2污染，由于冷链食品监管措施有效，没有冷链食品从业人员被感染。所以，
