On August 13, the outer package of a frozen chicken wing imported from Brazil in Shenzhen and a frozen shrimp imported from Ecuador in Xi’an were successively disclosed to be positive for the nucleic acid of the new coronavirus. According to incomplete statistics by Beijing News reporter, within two months, at least 10 cases of new coronavirus positive in food packaging were detected in China, which was related to imported frozen fresh food.
industry experts pointed out that the reason why NCV has “favored” imported frozen fresh packaging for many times may be related to the fact that the epidemic situation in foreign countries has not been completely controlled, the working environment of fresh processing industry is low-temperature and labor-intensive. There is no evidence that food is the source of infection of the new coronavirus. Consumers can do a good job in the purchase of protection, in cooking should pay attention to the key links of hygiene, and cooked food materials. However, there is no zero risk in food safety. If individuals are particularly concerned, they can choose not to eat.
on August 13, the office of the epidemic prevention and control headquarters of Shenzhen City announced that on August 12, a frozen chicken wing imported from Brazil with registration number of sif601 and batch number of 7720051522 was found in Longgang District of Shenzhen City, and the results of nucleic acid detection of new coronavirus were positive.
on August 13, the official microblog of Shaanxi Provincial Health and Health Commission issued a notice. At 9:00 p.m. on August 12, the local disease control department found that Ecuador frozen South American white shrimp with batch number 0063 and registration number 7057 in Fangxin frozen and non-staple food wholesale market in Xi’an had positive results of NCV nucleic acid detection.
it is worth noting that the registration number of the enterprises to which the batch of frozen shrimp belongs is different from that of the three Ecuadorian enterprises whose import was suspended by the customs in July. According to incomplete statistics by Beijing News reporter, including the two incidents mentioned above, at least 10 new coronavirus positive events related to imported frozen fresh packaging have been disclosed in all parts of China since July.
on July 10, the General Administration of Customs reported that Dalian customs and Xiamen Customs respectively tested positive for NCV nucleic acid from the inner wall and outer packaging samples of three batches of frozen shrimp containers imported from Ecuador; on July 14, Pingxiang, Jiangxi Province, reported that some consumers in this city had purchased frozen shrimp from Ecuador through the group purchase platform, while the inner wall and outer packaging of the same batch of products had been inspected On July 15, Shapingba District of Chongqing reported that the outer packaging of some frozen shrimp products from Ecuador in a frozen warehouse of Chongqing western logistics park was detected to be positive for NCV nucleic acid; on July 16, Yunnan reported that three samples of frozen shrimp from Ecuador were positive for NCV nucleic acid; on August 12, Wuhu, Anhui Province, it was reported that NCV nucleic acid was positive On November 11, the results of nucleic acid recheck of new coronavirus of frozen shrimp from Ecuador imported from a restaurant were positive.
at the same time, enterprises related to import and export of frozen food trade were also affected. On July 23, Dalian, Liaoning reported that new coronavirus was detected in food and environmental samples of Kaiyang seafood cold storage, processing workshops, dormitories, canteens and other food and environment samples, and new coronavirus was confirmed by employees in succession. On August 11, Yantai, Shandong Province reported that three enterprises imported frozen seafood products from the same foreign cargo ship at Dalian Port tested positive for NCV nucleic acid.
it is not difficult to find that the detection products and environment of the new coronavirus are closely related to the “imported frozen fresh food”. What characteristics does the new coronavirus like about the imported frozen fresh food? Zhu Yi, an associate professor at the school of food science and nutrition engineering of China Agricultural University, told the Beijing news that the above-mentioned pollution has nothing to do with fish, shrimp, chicken wings or packaging. The key lies in the cold chain environment. Under the low temperature of – 18 ℃ throughout the whole process, the virus that likes cold and fears heat can survive. The detection of continuous products is not a bad thing, which shows the tight control of epidemic situation in China.
on June 19, at the anti epidemic experience exchange meeting held by Hangzhou Customs, Li Lanjuan, academician of the Chinese Academy of engineering, also carried out science popularization on the survival environment of viruses, “generally, viruses can survive for a long time on the cold chain. Among the viruses we know and master, they can survive for more than 3 ~ 6 months at about 4 ℃ and long-term survival for 20 years below – 20 ℃. Different viruses have different survival times. ” It is worth noting that Li Lanjuan and the team stressed that compared with the known and mastered virus, the new coronavirus is a new virus. It is only 8 months since its appearance. Its understanding and low temperature tolerance ability need further research.
Zhong Kai, deputy director of Kexin food and nutrition information exchange center, told the Beijing news that in addition to the low temperature and closed process of processing and transportation, meat and seafood processing places are also densely populated. In addition, the foreign epidemic situation is not well controlled, so the probability of imported frozen fresh meat contaminated by viruses is relatively high.
Zhu Yi also believes that, like the contaminated elevator buttons and door handles, the outer packaging of imported frozen fresh food with new coronavirus may be contaminated with the droplets of the infected person. If the epidemic situation in the production area is not over, the risk of employees being infected is high, and the risk of food surface contamination is high. Under the situation of epidemic situation in many foreign regions, it is difficult for labor-intensive food processing factories to be independent. However, if pollution is not eliminated at the source, cold chain food and packaging will be detected positive continuously.
Based on the fact that new coronavirus is frequently detected in the outer packaging of imported frozen fresh food, the reporting bodies of Shenzhen epidemic prevention and control headquarters and Wuhu epidemic prevention and control headquarters remind consumers to be cautious in purchasing imported frozen meat products and aquatic products, and pay attention to personal protection to reduce aggregation and reduce the risk of infection with new coronavirus.
but that doesn’t mean you’re going to be vegetarian. The novel coronavirus of the national food safety risk assessment center Li Fengqin has publicly stated that there is no report of the new crown virus in the world. “There are a lot of scientific data that food does not infect new coronavirus, but it may be polluted.” Li Ning, deputy director and researcher of the national food safety risk assessment center, also said that based on the existing evidence, frozen aquatic products and frozen meat products are very unlikely to be used as infectious sources.
in Zhu Yi’s opinion, in the incident of imported frozen fresh food contaminated by NCV, the employees in the food and catering industry are the most at risk, and the risk of consumers is very low. However, consumers should also do a good job of protection, regularly clean the refrigerator, disinfect the parts of the kitchen that have been in contact with food, and do not buy smuggled frozen products of unknown origin.
as for how to properly handle food materials in the context of the epidemic situation, on June 18, the website of the national health and Health Commission pointed out that special care should be taken when handling raw meat and raw aquatic products to avoid cross contamination. Before putting them into the freezing layer, it is better to divide them into small pieces and package them separately, and the bags should be complete and undamaged; the food should be cooked and thoroughly cooked, and the raw aquatic products should not be eaten as far as possible; raw and cooked food should be avoided The products should be processed separately and stored in layers, and the use of public spoon and chopsticks should be advocated.
it was also pointed out that the key link hygiene should be paid attention to when the family prepares food. Especially after handling raw meat, poultry, aquatic products, etc., wash hands with soap and running water for at least 20 seconds. Do not wash raw meat products directly under the tap to prevent splashing pollution. Avoid rubbing eyes and nose with hands when touching fresh food during purchasing and making.
Zhong Kai believes that “there is no zero risk in food safety, especially in infectious diseases. If consumers want to” absolutely “avoid risks, they can only avoid imported frozen fresh food.” Compared with consumers, importers should do a better job in surface disinfection of frozen products, and operators should also pay attention to basic hygiene.
