Original title: Debate on the safety of the fresh cold chain of live viruses isolated from seafood packaging Source: Beijing Commercial Daily
As the epidemic fluctuates, the safety of imported seafood has hit many nerves. On October 18, live virus was detected and isolated in a positive sample of imported frozen cod, prompting a heated discussion. In fact, imported seafood has tested positive for the novel coronavirus in many places recently, infecting operators. A reporter for Beijing Business Daily interviewed several fresh food companies in Beijing to understand the current prevention and safety control plans for the cold chain.
Cold chain + double terminal insurance
On October 17, the China Disease Control publicly stated that according to relevant research and prevention and control practices, the novel coronary pneumonia is not a foodborne disease and no infections caused by eating have been found. food. So far, no cases of consumer infection have been found due to exposure to contaminated seafood from the cold chain, and the risk of infection for Chinese consumers is extremely low. At the same time, the relevant Chinese authorities have increased the control and disinfection of imported food from the cold chain for the new coronavirus. The general public should pay attention to keep them clean, separate raw and cooked food, and can buy and consume imported fresh food normally.
In an interview, a new cold chain practitioner who did not want to be named said: “China’s rapidly recovering consumer market has become the choice of more and more foreign exporters, but now all imported sources must be tested by the relevant departments. Operating companies will also perform batch nucleic acid testing on these products after they have obtained the supply. Only after the tests are qualified can they be sold. “
In addition to the best prevention and control measures for upstream companies, the sales terminals have also strengthened the prevention and control of imported food.
The relevant person in charge of Wal-Mart told the Beijing Business Daily reporter that the company attaches great importance to food safety and product quality. For imported frozen food and aquatic shellfish, they strictly follow national regulations and check the relevant qualification certificates from suppliers. At the same time, the company continually improves its own level of management and food safety operating standards to provide customers with safe and high-quality goods and services.
“For example, Wal-Mart continues to cooperate with BGI to conduct nucleic acid sampling tests for a number of aquatic products related to COVID-19. So far, nucleic acid test results for a number of aquatic products are all negatives “. action. Continue to strictly implement disinfection, epidemic prevention, and store monitoring, and provide customers and members with a healthy and safe shopping environment in accordance with relevant operational specifications.
A reporter for Beijing Business Daily learned that since August, every batch of imported seafood and poultry sold by Hema Fresh must have a negative nucleic acid test report before it can be put on shelves for sale, and accelerate display promotion in stores and applications across the country. Including imported live, chilled and frozen fresh aquatic products and meat and poultry, more than 1,300 commodities are involved. The reporter noted that in the Hema app, consumers can click on the “Traceability Plan” on the product detail page to view it. At the same time, you can also view the nucleic acid test report of the corresponding product batch by scanning the “trace source code” on the electronic price tag through the Hema app in the store.
Establish a traceability system
The CDC also stated that this discovery also reminds that while preventing the importation of foreign infected persons, attention needs to be paid to the risk of importing viruses from virus-contaminated cold chain elements abroad.
It is understood that the 84th meeting of the Beijing Leadership Group for the Prevention and Control of the New Coronary Pneumonia Epidemic and the 41st Meeting of the Joint Prevention and Control Coordination Mechanism of the Beijing administration that strictly enters Beijing requested that the standardized supervision of imported food from the cold chain be continued and established. The inbound traceability system implements a centralized closed-loop management. Related production and operating companies and logistics companies take the initiative to conduct inspections, conduct periodic inspections and include them in the scope of inspections.
Zhejiang requires cold chain foods imported after May 1, 2020 to be affixed with a “cold chain food traceability source code” on the outer packaging of the product. Food producers and operators must strictly carry out incoming inspections and use the “Zhejiang Cold Chain” system to enter information, assign codes and scan codes when products enter and leave the warehouse.
In addition, the Announcement of the General Administration of Customs No. 103 of 2020 (Announcement on the Implementation of Emergency Preventive Measures for Foreign Production Companies of Cold Chain Food Imported with Positive Nucleic Acids of the New Coronavirus) requires that the same company export cold chain food or its packaging to China If the first and second detections are positive for COVID-19, customs will suspend the acceptance of the import declaration of the company’s products for a week, and it will resume automatically after expiration; the same foreign manufacturer has been detected positive for COVID-19 for 3 times or more Yes, customs suspends the acceptance of the import declaration of the company’s products for 4 weeks and it will automatically resume after expiration.
Protect yourself strictly against international logistics
Should the prevention and control of the epidemic in the autumn and winter seasons focus on imported food from the cold chain and transnational express delivery? According to Health Times, Lin Bingliang, chief physician of the Department of Infectious Diseases of Sun Yat-sen University Third Affiliate Hospital, said that not only in autumn and winter, but also in all seasons, we must pay attention to international logistics, because international logistics express shipments are sealed and will not be exposed to sunlight. It can survive longer in the external environment such as ultraviolet rays, especially cold chain food, because the cold chain itself is in a frozen environment and is at low temperature, so we must pay attention to it every season .
Lin Bingliang pointed out that the survival of the virus is affected by temperature and humidity, but it is not the main influencing factor, but the virus lives longer in a low-temperature environment such as the cold chain. However, there are no precise data on specific survival time in the cold chain environment.
The data shows that relevant departments in China have conducted random inspections of novel coronavirus nucleic acid in cold chain foods. As of September 15, 24 provinces across the country had submitted 2.98 million test results, including 670,000 cold chain food and packaging samples, 1.24 million employee samples, and 1.07 million samples. environmental. Only 22 food and packaging samples were sent. The positive nucleic acid of the new coronavirus was detected in the virus, the viral nucleic acid load was low, and no live virus had been isolated before.
After the novel coronavirus was isolated from the outer packaging of imported seafood this time, the CDC suggested that industry professionals who are in close contact with cold chain products with high potential for contamination by the new corona virus at work, such as the handling, processing and sales of cold chain products People working in this area need to increase their awareness of protection, do daily protection, avoid direct skin contact with products from the cold chain that may be contaminated and work without removing work clothes that may become contaminated after contact with products from the cold chain. Upon completion, you should wash your hands and disinfect your hands immediately, and perform regular tests for nucleic acids.
In addition, the State Post Office issued on October 16 the “Proposals for the Production and Operation of the Express Postal Industry during the Period of Prevention and Control of Epidemics (Sixth Edition)”, which mentioned that prevention and control will be strengthened. of the epidemic situation in the processing of cold chain imported food express mail and the level will be raised. Control, cooperate with customs, epidemic prevention and other departments to carry out inspection, quarantine and disinfection of imported food from the cold chain; do not open the outer packaging without authorization during the delivery and transportation of cold chain imported food mail, and each batch of cold chain imported food mail is processed After that, transport vehicles, refrigerators of food and other equipment and appliances must be completely disposed of; staff directly contacting the cold chain imported food express mail should be relatively fixed, and personal hygiene protection should be strengthened during express mail processing, and masks should be worn throughout the process. Protective gear, such as gloves, and do a good job of detecting temperature before turning on and off.
