Neocoronaviruses can survive for long periods of time in the cold chain.
Yao Weirong, a professor and blogger at Jiangnan University and director of the Institute of Food Safety and Quality Control, said in an interview that frozen products generally need to be controlled at a temperature of about -18 degrees Celsius after they are packaged for long-distance transportation, then retailed, and ultimately reach consumers. In this cold chain process, viruses and other microorganisms will not be frozen and will not grow and multiply, and can always maintain the survival status. Similar to freezing and preserving strains of bacteria, cold chain products can restore the activity of viruses after thawing to room temperature.
Currently imported food packaging infection, the greatest likelihood from the product in the post-production warehousing, cold chain transportation, sales process, the packaging is infected with the new crown of the person in direct contact, or the entire process of the air floating in the new crown of the virus and caused by.? Yao Weirong said, in the whole cold chain process, because of the temperature, any of the above links any contact surface as long as the contamination, the new crown virus has been alive.Shopping for imported frozen products pay attention to good personal protection
