On the morning of November 12, Tianjin The Jinnan District Center for Disease Control found that a mixed sample of a mixed sample tested positive for nucleic acid in a cold storage of Jinfulin Frozen Wholesale Market. The day before, a copy of imported halibut with positive outer packaging was found in an aquatic product wholesale store in Jinghai District, which also came from here after traceability.

Since Tianjin notified the 138th local case, imported cold chain food has become the focus of epidemic prevention and control. In the early morning of November 8, a cold storage loading and unloading worker in the city was diagnosed with new coronary pneumonia.

The patient’s biggest doubt is that he had contact with a batch of frozen pig elbows that arrived in Tianjin from Bremerhaven, Germany 20 days ago. Gene sequencing results show that the virus is highly similar to the strains circulating in North America from March to June, and belongs to the L genotype European family branch II (North American branch). Subsequently, a new confirmed case was added in Tianjin, who drove a truck to the same cold storage to load goods. Another asymptomatic infection was found in the city’s cold chain practitioners and frozen goods nucleic acid testing.

In recent months, imported cold chain foods have frequently been found to have tested positive for nucleic acid, which has become the main reason for repeated epidemics in some areas. Why does cold chain food become the”latency” of the virus? How big is my country’s demand for imported cold chain food? In view of its potential risks, how should various departments scientifically prevent and control them?

More than 10 provinces have detected positive imported cold chain nucleic acid

On November 7, Tianjin Binhai New Area Epidemic Prevention and Control Headquarters received from Shandong Province Decheng District, Decheng District, Dezhou City, reported that the cold-chain food COVID-19 epidemic prevention and control work class reported that frozen pigs imported from Germany through the Dongjiang Bonded Port Area of ​​Binhai New Area tested weakly positive for COVID-19.

Two days ago, this batch of 28.1 tons of cargo was sent from Tianjin Port Hailian Cold Storage, and on the day it arrived at the Feima Market in Decheng District, it underwent routine nucleic acid sampling. After the three-level disease control departments of Decheng District, Dezhou City, and Shandong Province, the results were confirmed to be positive.

Tianjin Port is an important import port for China’s cold chain foods. Imported frozen meat accounts for nearly one-third of the country’s meat imports. Because the goods involved in the epidemic have flowed into Dezhou, Shandong, Taiyuan, Shanxi, and Baoding, Hebei, the three places immediately stepped up investigations.

The reporter found that since June this year, Beijing, Liaoning, Anhui, Fujian, Jiangxi, Shandong, Guangdong, Shaanxi, Jiangsu and other more than 10 provinces have been importing The new coronavirus nucleic acid was detected on cold-chain food or packaging.

On June 11, after there were no new local confirmed cases in Beijing for 56 consecutive days, local cases reappeared, and the”source” of the infection was locked at the new agricultural wholesale market. A paper jointly published by Beijing Center for Disease Control and Prevention, Beijing Preventive Medicine Research Center, Chinese Academy of Medical Sciences, Chinese Academy of Sciences and other units later pointed out that the new outbreak virus in Beijing originated in the seafood area where chilled salmon is located.

On July 3, Dalian Customs detected positive nucleic acid from the new coronavirus in a sample of the inner wall of a container loaded with frozen vannamei shrimp produced in Ecuador and three outer packaging samples of the shrimp. Since July 22, staff in the seafood processing workshop of Dalian Kaiyang World Seafood Co., Ltd. have been notified that they have been infected with the new crown virus. The characteristics of the epidemic suggest that the processing workplace of frozen seafood products is conducive to the spread of the new crown virus.

In late September, an epidemic in Qingdao Port emerged. On the 24th, two cold chain product stevedores were diagnosed as asymptomatic infections during the inspection of the”all inspections” personnel. In the subsequent traceability of the epidemic, live virus was detected and isolated from positive samples of imported frozen cod outer packaging. This is the first time in the world, suggesting that”the new coronavirus has the possibility of long-distance cross-border import with cold chain goods as carriers.”

The new outbreak in Beijing lasted 40 days, with a total of 335 confirmed cases, including 5 critical and 21 severe; Dalian”7.22″ epidemic lasted 39 days, and a total of 92 local confirmed cases were reported , There are 26 cases of asymptomatic infections in the local area; only 2 cases of asymptomatic infections were found at the time of the Qingdao port epidemic, and all close contacts were lifted from isolation after 16 days.

“The three outbreaks were discovered earlier than all, and their scales are getting smaller and smaller.This is the result of our continuous learning and summing up of experience, and timely detection of the early Only those who are infected can control the epidemic in its infancy.” said Wu Zunyou, chief epidemiologist at the Chinese Center for Disease Control and Prevention.

Fresh food imports are highly dependent on cold chain logistics

With the potential infection risk

>

In recent years, the consumption level of Chinese residents has continuously improved, and the volume of imported food has increased rapidly.

On November 7, the China Chamber of Commerce for Import and Export of Foodstuffs, Native Produce and Animal Husbandry issued the”Report on China’s Imported Food Industry in 2020″. 189. In terms of value, among the 17 categories, the top three are meat and products, aquatic products and products, and dairy products, with imports exceeding 10 billion U.S. dollars. The top five sources of food imports are New Zealand, Australia, Thailand, Indonesia, and Brazil. The top three ports are Shanghai Port, Tianjin Port and Shenzhen Port.

The report stated that although the current new crown epidemic has greatly affected international exchanges, it is expected that imported food will continue to maintain double-digit growth in 2020.

Among the many imported foods, a considerable number of categories, including fresh food, are highly dependent on cold chain logistics.

Compared with ordinary logistics, cold chain logistics has three characteristics, also known as the 3T principle, that is, product quality depends on cold chain storage temperature, circulation time, and storage resistance.”The core of cold chain logistics is the whole process of continuous chaining. Once the chain is broken and the temperature is released, it will have an irreversible impact on the goods. Even if the following links are done well, it is futile.” Secretary of the Cold Chain Logistics Professional Committee of China Federation of Logistics and Purchasing Chang Qin Yuming said.

Under the epidemic, the cold chain logistics is accompanied by a potential risk of infection. Wu Zunyou said that even with ordinary cold chain transportation, the virus can survive for several weeks. If it is contaminated items, including food or outer packaging, in areas with a high incidence of new crown epidemics, they can be transported through the cold chain to bring the virus to a non-epidemic area, thereby causing contact transmission.

Make up for the lack of domestic supply

Imported cold chain food cannot be”one size fits all” and completely banned

Then Should there be a “one size fits all” cessation of importing cold chain foods, as individual voices call for it? The industry believes that, for the time being, this is”caught because of choking, and it is not realistic.”

The reason is that the risk prevention and control of cold chain products has entered the new normal stage of epidemic prevention. Qin Yuming pointed out that on the one hand, foreign epidemics continue to spread, one after another, many countries ushered in the second wave of epidemic peaks in autumn and winter; All imported products are shut out—this is already consensus and common sense.

The majority of consumers do not need to worry too much, but they need to pay attention to food hygiene and take daily precautions. Li Fengqin, director of the Microbiology Laboratory of the National Center for Food Safety Risk Assessment, said that a large amount of scientific data shows that food will not be infected with the new crown virus, but it may be contaminated:one is contaminated by water and packaging materials that contain the virus, and the other is food that carries the virus. Contamination of processors.

Li Fengqin suggested that operations should be strictly regulated in the production and operation process, and the food processing environment including food packaging materials should be disinfected. It is strictly forbidden for virus carriers or infected persons to sell food.

At present, both the customs and other departments have deployed strict inspection, disinfection and control methods. The problematic goods exposed are accounted for by the overall goods In comparison, it is quite a small part.” Qin Yuming said.

National customs to increase imports of cold chain food

Quarantine efforts

November 12, At the press conference of the Joint Prevention and Control Mechanism of the State Council, Bi Kexin, director of the Import and Export Food Safety Bureau of the General Administration of Customs, said that the national customs has further increased the quarantine of imported cold chain food.

  • First, to further strengthen source control, communicate and negotiate with the competent authorities of all 109 countries that have cold chain food export to China.
  • The second is to suspend the export of products from companies that have been infected by a cluster of employees, involving 99 manufacturing companies in 20 countries.
  • The third is to strengthen the risk monitoring of the new coronavirus in imported cold-chain foods. A total of 873475 samples were sampled and tested, and 13 positive nucleic acid results were detected.
  • Fourth is to implement emergency preventive measures after the positive is detected.

“Because one batch of frozen pomfret imported from Indonesia was found to be positive for the new coronavirus nucleic acid in one product sample, in accordance with the regulations of the General Administration of Customs Announcement No. 103 of 2020 , The national customs will suspend acceptance from today…” Open the”Customs Today” channel on the official website of the General Administration of Customs, and update the emergency preventive measures on imported food in real time.

According to relevant regulations, If cold chain food or its packaging is tested positive for the new crown virus nucleic acid 2 times before being exported to China, the customs will suspend accepting the import declaration of the company’s product for 1 week and be detected 3 times And above, the import declaration is suspended for 4 weeks.

According to the characteristics of imported cold chain food logistics, after the completion of the new crown virus detection and sampling work, the inspections at the ports, transportation, warehouse storage, wholesale and retail, etc. were carried out for the first time. All personnel in our territory should implement preventive and comprehensive disinfection before contact.

Scientific and precise prevention and control, and perfect retrospective management

Scientific prevention and control and precise policy implementation have always been our important experience in the fight against epidemics. So, what should be done in the face of the potential spreading risk of imported cold chain food?

The reporter combed through the relevant epidemic prevention and control guidelines issued by various regions and found that key links and key places have become common concerns. Especially for key locations such as processing enterprises and cold storage, agricultural batches, supermarkets, and catering services, localities have strengthened normalized epidemic monitoring and risk early warning in a timely manner.

Experts suggest that special attention should be paid to the disinfection and quarantine of raw materials during processing and packaging. During transportation and storage, refrigerated warehouses, vehicles and tools must not be careless. During the sales process, bazaars and retail companies must strictly implement the purchase inspection and registration system, and business units engaged in food wholesale must strictly implement the sales registration system, and pay attention to timely disinfection.

There are cold chain traceability systems in many places across the country↘

Recently, in an imported fresh food store in Huiji District, Zhengzhou City, Henan Province, Mr. Sun Proficiently opened the mobile Alipay and scanned a QR code on the outer packaging.

“Beep!” The screen shows that this is pangasius from Vietnam, with an inspection and quarantine certificate. This system enables imported cold-chain food to achieve”tracing of origin, traceability of circulation, and traceability of whereabouts”.

From November 1,”Beijing Cold Chain” Food The traceability platform was officially put into operation, and Beijing imported refrigerated and frozen meat and aquatic products fully implemented”on-code” traceability management.

Incorporate cold chain prevention and control into normal management

Recently, the State Council’s Joint Prevention and Control Mechanism issued the”Work Plan for Preventive and Comprehensive Disinfection of Imported Cold Chain Food.” The”Plan” requires that all localities implement the entire closed-loop control and traceability of imported cold chain food. The division of labor among customs, transportation, health, market supervision, local governments, and related production and business units has been clarified one by one.

“This is an important policy document for the normalization of the prevention and control of the new crown epidemic in China.” Wu Zunyou said,”After many imported cold chain foods caused local new crown epidemics, the country has not simply banned the import of cold Instead, the control of the new crown epidemic that may be caused by imported cold chain food contamination is included in normal management, and the risk is controlled to the lowest level.”
