Influence of SARS-CoV-2 on the quality and safety of cold chain transportation food

ABSTRACT

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause severe respiratory syndrome in humans. Since the outbreak in 2019, it has been interfering with people's normal life. Retrospective study and news showed that SARS-CoV-2 was found on the outer packaging and surface of many imported cold chain foods, especially the infection case of port handlers in Qingdao, which once again pointed the spearhead at cold chain transportation. A large number of studies have shown that SARS-CoV-2 can survive at low temperatures and maintain high infectivity. Meanwhile, it also showed strong survivability and stability on the surface of plastic packaging and various foods, making imported cold chain food a medium and triggering another outbreak of the disease. This paper mainly summarized the biological characteristics and transmission process of SARS-CoV-2 in cold chain logistics, and the prevention and control measures for cold chain transmission, which provides guidance for the control of cold chain logistics and frozen food in the future, and provides certain reference for food quality and safety and epidemic prevention and control.
