Dalian outbreak or started in the seafood processing workshop! Kaiyang has been sealed off the shelf.

On the morning of August 3, the information office of Dalian Municipal Government held the 29th centralized release of the prevention and control of the outbreak of new crown pneumonia in Dalian.
, director of the Dalian Municipal Health and Health Commission, said at a press conference held by the local government that the outbreak was mainly a cluster outbreak related to the processing and treatment of frozen seafood products.
Through a preliminary epidemiological investigation, the case in this outbreak as early as July 9, Kaiyang Seafood company cases occurred earlier than cases outside the company, suggesting that the outbreak may start in Kaiyang seafood processing workshop, and then spread rapidly in the processing workshop, and spread outwards.
60 workers and managers were infected at the workshop, with a rate of 61.9 per cent.
of the outbreak suggest that the processing and treatment of frozen seafood products in the workplace is conducive to the spread of the new coronavirus.
the possibility that this outbreak was caused by overseas imports cannot be ruled out.
the virus gene sequence from samples of infected people inside and outside Kaiyang company is highly iono-like, indicating that the Dalian outbreak is the same transmission chain.
Through case flow and big data matching, no clues were found that the outbreak was associated with recent cases in Beijing and Xinjiang, and the genetic sequencing results of the case specimens showed different genotypes of the new coronavirus prevalent in China, and also excluded the association with the new crown outbreaks in Urumqi, Beijing Xinfa, Shulan, Harbin and Weifenhe.
this outbreak can initially rule out the possibility of domestic local case transmission, presumably caused by overseas imports of the possibility can not be ruled out, the source of the outbreak under the guidance of national and provincial expert groups in a tight process.
(Dalian City Health and Health Commission) the new crown outbreak is always related to seafood? How to deal with it? From wuhan South China Seafood Market at the beginning of this year, to Beijing Xinfa district farmers market related seafood products, from Dalian, Xiamen Customs in Ecuador produced part of the frozen South American white shrimp packaging samples tested positive for new coronavirus nucleic acid, to the recent new local new crown pneumonia confirmed cases in Dalian, the vast majority of the confirmed cases related to Dalian Kaiyang Seafood Company.
the new crown pneumonia outbreak always has something to do with seafood? How should I respond? Sun Dawen, a member of the European Academy of Sciences, a member of the International Academy of Food Sciences, and a professor at South China University of Technology, told the Southern Daily News that from the point of view of scientific rigour, it is still not possible to confirm that seafood and aquatic products can be infected with the new coronavirus, but the above-mentioned outbreak cases show that the relevant market sales of cold chain fresh food is indeed a potential risk.
" outbreak is no small matter, security is no small matter.
" Sun Dawen suggested that the safe supply of cold-chain food should be strictly guaranteed, and that all possible ways of spreading the new coronavirus should be cut off scientifically and effectively.
pointed out that from a scientific point of view, cold chain for food preservation, but also for the virus "fresh."
once food in the circulation of the new coronavirus, the traditional cold chain low temperature high humidity environment, but more conducive to the long-term virus to maintain the vitality of infection.
" is therefore particularly important for the regulation of imported cold-chain foods and all aspects of circulation.
improve China's imported food foreign and domestic policy is the short-term blocking of the new coronavirus from abroad into the territory of the most effective means.
," Sun said.
addition of new coronavirus nucleic acid testing as a mandatory item to strengthen the cold chain food import supervision, Sun Dawen put forward a number of recommendations.
, the addition of new coronavirus nucleic acid testing for imported food mandatory items.
Sun Dawen pointed out that the current overseas epidemic has not been effectively controlled, some countries exist "with the epidemic to resume work" phenomenon.
, some carriers of the virus and asymptomatic infections cannot be effectively screened because of differences in nucleic acid detection capabilities and criteria for diagnosis.
such groups, if they work in food-related industries, may be able to cause food contamination in the production, processing, storage and marketing of food.
to this end, he suggested that imported food to increase sampling efforts, and the new coronavirus nucleic acid testing as the current special period of imported food mandatory items, including the food itself and food packaging testing.
once checked out, the product must not enter the customs.
second, exporting countries are required to provide detailed food testing reports and path reports.
Sun Dawen suggested that all circulation links within the exporting country before food is exported should generate a detailed path report to be handed over to the Chinese Customs for reporting.
third, the food safety risk classification is implemented for exporting countries.
specifically, follow China's current classification criteria for the risk level of the new crown pneumonia outbreak and class class out food safety risks for exporting countries.
countries with adequate epidemic prevention and control, adequate nucleic acid detection capabilities and stringent food export standards are included in the list of green countries for food imports.
at the same time, countries and regions with severe outbreaks and weak prevention and control are included in the red warning list, and on the basis of not violating relevant international trade agreements, policies are formulated to reduce or stop food imports from such countries or regions.
china's multi-site market regulators to deal with frozen South American white shrimp imported from Ecuador.
processing of food raw materials bearing in mind the principle of "raw separation" on strengthening the cold chain food circulation supervision, Sun Dawen also put forward a number of recommendations.
, we should establish and improve the traceability system of imported food.
for imported food, to record in detail its circulation links after entry (storage and transportation, sales, terminal to go).
once there is an outbreak of food-source virus infection, the traceability system can be used to quickly target the source of the outbreak.
, we should strictly follow the safety operating procedures, strictly prevent the latent spread of viruses.
food-related practitioners should undergo strict pre-job medical examination and training, establish a health tracking "one-day-one-report" system, and strengthen the personal protection and health management of food workers.
for cold chain food circulation links involved in transport, equipment facilities and places, to carry out regular professional killing, blocking the transmission of the virus.
plan for food safety emergency disposal in advance, focusing on market management, personnel isolation, killing cleaning, waste disposal and other work after the outbreak.
, strengthen food safety publicity and promote healthy eating.
to guide the people to develop good food safety practices, in the food raw materials processing, bearing in mind the "raw separation" principle, to avoid the secondary contamination of cooked food.
special period, the people are advocated to avoid raw food eating habits.
, increase food safety supervision, focusing on individual micro-enterprises.
at the government level, we should strengthen supervision of the food industry and strictly examine the operational qualifications of enterprises such as production, processing, storage and transportation, retailing and catering.
, we should strengthen the supervision of large-scale commercial super, integrated market and other procurement-intensive areas.
the other hand, because individual micro-enterprises in the professional management and supply stability may have certain risks, but also should increase the intensity of such enterprises.
