Imported cold chain food detected nucleic acid positive, how to prevent imported viruses while "cold" into?

Recently, the national import cold chain food traceability management platform line operation, the basic realization from customs entry to production and processing, wholesale and retail, catering services, the whole chain of information tracing ... Import cold chain management has been strengthened, but there are still practitioners infected.
In the evening of December 3rd, Bai Yansong talked to Zhang Liubo, chief expert in disinfection at the CDC, and Xia Wei, a three-level researcher in the Food Coordination Department of the State Administration of Market Supervision, on how to ensure the safety of employees and imported goods. Import cold chain, how to block the import of "virus"? How can imported cold chain protection be safer in the face of these problems? What additional measures can be taken to reduce human infection? How should some cold-chain foods imported from small or informal sources be regulated? Disinfecting personnel are not hundreds of poisons do not invade china CDC disinfection chief expert Zhang Liubo: Qingdao this wave of the first case of asymptomatic infected people may have two conditions - (1) may be infected during the handling process, (2) may be infected in the disinfection process.
actually disinfecting personnel and medical workers, is not a hundred poisons do not invade, so in the process of disinfection, in the process of operation there is a risk of infection.
to strengthen their own protection, do a good job of related protection work is very important.
do a good job of protecting the sterilizer? Zhang Liubo, chief expert in disinfection at the CDC: (1) It is best to have qualified personnel engaged in disinfection.
this year, the Ministry of Human And Social Affairs has dedicated disinfection workers as a profession, we should strive to do in accordance with the professional requirements of disinfection workers.
have not yet obtained the qualification of disinfection staff, we must train qualified to work later, disinfection and self-protection knowledge can have some understanding.
(2) be sure to do a good job of their own protection.
Cold chain food disinfection personnel are also good, staff is good, not only to wear a lot of clothes, but also to do a good job of protection, but also to do heavy physical work, so protection may be more difficult than usual, but again difficult to ensure safety.
(3) be sure to pay attention to good hand hygiene.
contact with cold chain items, be sure to disinfect or clean your hands in a timely manner.
vaccine is recommended if conditions are in use.
(5) if you can achieve centralized accommodation, it is still necessary to facilitate timely monitoring of their own health.
urgent need for effective disinfection methods at low temperatures China CDC disinfection chief expert Zhang Liubo: disinfection at low temperatures is a new problem this year, the previous disinfection measures are carried out at room temperature.
low temperature may have a significant impact on the disinfection effect, some commonly used disinfectants, commonly used disinfection methods may not be useful.
this time, there is an urgent need for some effective disinfectants and disinfection methods at low temperatures, which is a new problem that has not been encountered before, so it is also the most difficult place.
China CDC: low-temperature frozen disinfectant will soon be successfully developed China CDC chief expert in disinfection Zhang Liubo: after the temperature is low, the disinfection capacity of disinfectant significantly decreased, especially after freezing, there will certainly be no effect.
even if it doesn't freeze, its disinfection effect will be many times lower.
so in this case, we urgently need disinfectants that are effective at low temperatures.
In fact, after the outbreak in the new place, the CDC has begun to carry out relevant research, so low-temperature frozen disinfectants can soon meet with you, China CDC will be related to the formulation, use of methods, completely open, free of charge to the community.
we have done more than 5 months of research, we will certainly strive to solve this problem as soon as possible.
is cold chain food safely managed? Zhang Liubo, chief expert in disinfection at the CDC: There is a set of measures for the management of cold chain foods.
first step is disinfection.
we have two options, the first is to basically restore the surface of cold-chain foods to normal temperature and then disinfect.
second, for those who must be disinfected at low temperatures, for those who test positive, the method of sealing is used, or direct incineration, destruction, landfill, and these methods are used for treatment.
the situation we are facing now is that we have to disinfect the surface of all cold-chain foods, so the task of this piece will be more difficult, and we urgently need some new technology to supplement it."
more than 90% of the country's imported cold-chain food traceable to the remaining 10%? At present, the national import cold chain food traceability management platform access to 9 provinces (cities), cold chain food first station imports accounted for more than 90% of the country.
Wei, a three-level researcher in the Food Coordination Department of the State Administration of Market Supervision: The nine key provinces we chose at the beginning were all more ports and larger imports.
we put these nine provinces into the information traceability, in fact, is also to highlight the focus, starting with key areas, and then gradually expand to the whole country.
10% is not to say that it can not be traced, the same can be achieved retrospective, but in a slightly different way and information means.
this 10% mainly through paper ledgers, purchase vouchers and other ways to record traceability information, which is also the Food Safety Law put forward a clear requirement.
Whether it is information tracing, or this kind of paper ledger, regulators will go to the site inspection, urging enterprises to truthfully record product names, specifications, quantities, batches, including in and out of the goods records and other key information.
so 10% is actually under our control, so rest assured.
of cold-chain foods imported through informal channels, how can they be regulated? Xia Wei, three-level investigator of the Food Coordination Department of the State Administration of Market Supervision: The national traceability system we have built is actually a three-level processing system, including a platform at the national level, a provincial platform, and an enterprise-level platform.
conditional enterprises can build their own traceability system, their own traceability, small, even small micro-enterprises, it does not have the technology or ability to build traceability system, at this time the provincial platform to play a role.
provincial platform, in fact, retrospective management, as well as public services to help these enterprises without self-built systems to provide services.
So our consideration is whether it is large, medium, or small enterprises, as long as the operation of imported cold chain food, we must incorporate it into the traceability, the realization of the source can be traced, go to traceable.
sources of food from informal sources, in fact, whether there is an outbreak or not, this part is informal, but also has been the focus of the relevant departments to combat.
