Risk management of imported cold-chain foods during the COVID-19 pandemic

Since July 2020， nucleic acids of novel coronavirus SARS-CoV-2 were frequently detected in cold chain food imported to China， making imported food being a potential risk to the COVID-19 outbreak. Based on the epidemiological characteristics of SARS-CoV-2， imported cold-chain food and their packaging may become the carriers of SARS-CoV-2 in long-distance cross-border transportation. In each aspect of stakeholders including governmental supervision， manufacturers and consumers， China should strengthen the risk management of imported cold-chain food to ensure the safety， especially pay attention to the health protection of industry workers in close contact with cold -chain food.
