Risk Assessment for the Outer Packaging in Inbound Products as a Medium of Introduction and Transmis-sion
The outer packaging in inbound products during cold-chain can induct and disseminate COVID-19.The fact was proved.This paper takes the fact as an example to asses the pathogens'risk.The outer packaging car-ried and disseminated COVID-19 by respiratory tract and contact.Therefore,similar virus has a high risk.How-ever,the induct risk of non-cold chain products is high,and the spread risk is not high.Due to measures such as preventive disinfection,there was no report about COVID-19 spreading.Therefore,The supervision of high-risk pathogens must be strengthened.And precise risk assessment should be carried separately.If the products has come from epidemic areas,high pathogens'risk assessment of the outer packaging should include virus host,transmis-sion vector,transmission mode,disinfection effect and so on.
