Original caption: Many places report positive nucleic acid detection in food or cold chain packaging, can you eat imported food?
Since June, frozen vannamei shrimp, frozen salmon, frozen chicken wings, frozen pork, frozen beef, frozen octopus, and other imported frozen foods, especially the outer packaging of fresh frozen products, have been continuously detected as positive for nucleic acid. of the new corona virus, involving several countries across the country. province.Many people are beginning to worry if they can still eatChilled frozenfood? Is the inventory from the refrigerator in the house eaten or thrown away?
Where did the virus on the packaging come from?
Wu Zunyou, chief epidemiologist at the China Center for Disease Control and Prevention, previously stated that the air in some places contains viruses, and when dust with virus particles falls into the air, it contaminates these elements. If these elements are humid or the temperature is very low, the virus will survive longer.
The greatest possibility of the new corona virus in imported frozen food packaging comes from the direct contact of infected persons with the new corona in the outer packaging during the production, packaging, storage, transport and sale of the product, or the new corona virus floating in the air Even with the ordinary transport of the cold chain, the virus can survive for several weeks. Contaminated food or outer packaging is transported through the cold chain, which can carry the virus to a non-epidemic area, thus causing contact transmission.

Zhang Boli, an academic at the Chinese Academy of Engineering and president of the Tianjin University of Traditional Chinese Medicine, recently said in a media interview that the epidemic situation abroad is worsening and the number of asymptomatic infections is increasing. In addition, winter and cold weather have caused the new corona virus to survive on the surface of the polluting body for longer. Although the origin of the spread of the epidemic has not yet been determined, imported cold chain items should be worth our vigilance and prevention. If this lagoon is not blocked for a day, it is very likely that the same danger will appear in other places. We can import foreign personnel. It is blocked by strict isolation and general overhaul, but the prevention and control of frozen food or products in the ‘dark place’ requires stricter control. “
Although cold chain logistics have a potential risk of infection, it is unrealistic to suspend imports of cold chain food.
Qin Yuming, general secretary of the Cold Chain Logistics Committee of the China Federation of Logistics and Purchasing, pointed out that China needs a large number of imported products to compensate for the lack of domestic supply, so not all products can be excluded. imported. In daily life, as long as you pay attention to food hygiene and take daily precautions, refrigerated frozen food can be eaten normally.
How to buy and eat frozen chilled food safely?
The Beijing Municipal Center for Disease Control and Prevention has come up with three suggestions on how to buy and eat frozen frozen food safely:
When buying:
1. Go to the usual supermarkets or markets to buy fresh produce When shopping, you can use disposable plastic bags to cover your hands to select fresh frozen foods, avoid direct contact with your hands, and use masks correctly.
2. When buying prepackaged frozen refrigerated food, pay attention to the content on the food label such as production date, shelf life, storage conditions, etc., to ensure that the food is within the shelf life .
3. Wash your hands with soap or hand sanitizer immediately after shopping. Before washing your hands, do not touch your mouth, nose, eyes and other parts.
4. For purchases abroad and products from overseas countries or regions, including the purchase of frozen food abroad, please pay attention to the customs food quarantine information and disinfect the outer packaging well.
When cleaning and processing:
1. Keep kitchen and utensils clean and wash your hands before handling food.
2. Separate raw and cooked foods. Containers (pots), knives, cutting boards and other utensils used to process fresh frozen food should be placed separately, cleaned and sanitized in time, and avoid mixing with directly imported food processing utensils to avoid cross contamination.
3. Store fresh frozen food in the freezer compartment of the refrigerator. Do not keep them for a long time. Store in layers with cooked foods.
4. After washing or handling frozen refrigerated food, wash your hands before handling cooked food.
5. The kitchen must be ventilated and clean, and the environment and the dishes and kitchen utensils must be disinfected when necessary.
When cooking and eating:
1. When cooking and eating frozen refrigerated foods, processed seafood must be fully cooked. The general principle of cooking is to keep it for 10-15 minutes after boiling.
2. Try to avoid eating raw, half-raw, wine-soaked, vinegar, or salty seafood.
3. When two or more people eat together, remember to use public chopsticks and spoons to reduce cross infection and reduce the incidence of infectious diseases and foodborne illnesses.
4. For shellfish that has not been eaten (already cooked), store it in the refrigerator, eat it as soon as possible, and be sure to fully heat it before eating again, and the core temperature should reach 70 ° C or higher.
Also, after eating frozen chilled food, once symptoms of fever or diarrhea occur, seek medical treatment at a fever clinic in time and actively report consumption time, food types and source of ingredients to help in diagnosis and treatment.

Imported cold chain food can be traced
Since November 1, the “Beijing Cold Chain” food traceability platform was officially launched, and imported Beijing frozen meat and aquatic products have fully implemented “code envelope” traceability management. When citizens buy imported frozen and frozen meat and aquatic products in shopping malls and supermarkets, they can scan the electronic traceability code to check the relevant information of the purchased food.
△ Advertising posters for the cold chain in the Beijing supermarketOn November 16, Shanghai issued the “Notice on the Implementation of High-Risk Imported Cold Chain Food Transit Inspection”, which requires that all imported high-risk cold chain foods be stored, processed and sold. in town to be inspected for nucleic acid testing and disinfection certificates. Imported high-risk cold chain foods entering the transit inspection warehouse pass the nucleic acid test and the outer packaging is sanitized. The transit inspection warehouse will notify the owner of the delivery and issue the “Shanghai Import Cold Chain Food Delivery Certificate”.
As early as September, Zhejiang Province had requested that the “Cold Chain Food Traceability Source Code” be placed on the outer packaging of imported cold chain foods after May 1, 2020. Zhejiang clearly stipulates that once a positive report of the novel coronavirus test is received for cold chain foods inside and outside the province, the ‘Zhejiang Cold Chain’ system should be used to track the source and accurately locate flow the same batch of food in 2 hours, and dispose of it quickly and properly. .
At present, Beijing, Shanghai, Zhejiang, Sichuan, Fujian, Gansu, Hebei, Shandong and other provinces have implemented the traceability of imported food from the cold chain.
National customs to increase the quarantine of imported food from the cold chain
On November 12, at a press conference on the Joint Prevention and Control Mechanism of the State Council, Bi Kexin, director of the Office of Import and Export Food Safety of the General Administration of Customs, said that the national customs has increased even more so the quarantine of imported food from the cold chain. One is to further strengthen source control and communicate and consult with the competent authorities of the 109 countries that export cold chain food to China. The second is to suspend the export of products from companies that have been infected by a group of employees, which involves 99 manufacturing companies in 20 countries. The third is to strengthen risk monitoring of imported food from the cold chain for the new coronavirus. A total of 873475 samples were sampled and analyzed, and 13 positive nucleic acid results were detected. The fourth is to implement emergency preventive measures after the positive is detected. In accordance with the relevant regulations, if the cold chain food or its packaging tests positive for the new coronavirus nucleic acid 2 times before, the customs will suspend the acceptance of the import declaration of the company’s product for 1 week. If it is detected 3 times or more, the customs will suspend the acceptance of the import declaration for 4 weeks. .
According to the characteristics of the imported food logistics of the cold chain, after completing the detection and sampling work of the new corona virus, comprehensive preventive measures should be implemented in the links of port inspection, transport, storage, wholesale and retail, etc. Disinfection treatment. During the epidemic, citizens only need to carry out daily protection and disinfection, and they can still eat the cold chain products circulating in the market with confidence.
