Four possible experts： there is no reason to go to the table.

　　　　　　 CCTV News:The General Administration of Market Supervision issued an announcement last night (18th). In response to media reports that pork products such as dumplings were positive for African swine fever virus nucleic acid, the General Administration of Market Supervision and the Ministry of Agriculture and Rural Affairs have asked enterprises to immediately trace the source of pork raw materials and dispose of pork products. At present, the two departments have sent a joint inspection team to investigate and verify the relevant situation, requiring pork products manufacturers to further strengthen the control of pork raw materials, implement the inspection and quarantine ticket inspection regulations, improve the African swine fever detection and review system, and prevent infected pork raw materials from entering the food processing link. Enterprises that fail to fulfill their prevention and control responsibilities as required will be severely punished once they are found.

　　　　　　 Sanquan Food: Suspected batch products have been sealed.

　　　　　　 In this incident, it was revealed that several batches of soup dumplings produced in Sanquan Food were suspected of African swine fever virus. In this regard, Sanquan Food announced yesterday (18th) that the company had sealed all relevant suspected batches of products from all sales channels for the first time. At the same time, the Henan provincial government has sent a joint investigation team to Hunan and Gansu respectively to check the relevant situation with relevant local departments.

　　　　　　 Expert: There are four possibilities for quick-frozen food to be infected with virus.

　　　　　　 After the incident was exposed, netizens raised some questions, such as: How did African swine fever virus flow into frozen food? In this regard, a reporter from Voice of China interviewed Yi Zhu, an associate professor at the College of Food Science and Nutritional Engineering of China Agricultural University. Yi Zhu pointed out that the most extreme situation is that sick and dead pork is mixed into the production process. In addition, there are three possibilities.

　　　　　　 Yi Zhu, Associate Professor of College of Food Science and Nutritional Engineering, China Agricultural University, said: "The first reason is that the detection methods have been greatly improved and the detection sensitivity is very high. Even if there are only a few viruses, it can be detected. The second reason is that when pork was imported and slaughtered, some pigs with latent disease were not identified. It has been carrying African swine fever virus, the incubation period is about 5 to 19 days, and there is no disease. If you don’t do special disease detection, you can’t see it with the naked eye, so that such pork is mixed into the supplied products. The third reason is that there is no problem with pork itself, but it is polluted by African swine fever virus in transportation, processing and packaging. "

　　　　　　 Expert: It will not infect people and will not affect food safety.

　　　　　　 Another question that everyone cares about is, is African swine fever virus harmful to human body? Can pork still be eaten?

　　　　　　 Experts from the Ministry of Agriculture and Rural Affairs have responded to this repeatedly mentioned question. African swine fever is not zoonotic and will not infect people. At the same time, it will not infect other animals except pigs and will not affect food safety. In addition, experts also said that high temperature can kill African swine fever virus, and continuous heating at 60 degrees Celsius for 20 minutes can kill the virus. Therefore, everyone can safely consume the quarantined pork.

　　　　　　 However, is African swine fever virus harmless to human body? In an interview with Yi Zhu, an associate professor at the College of Food Science and Nutritional Engineering of China Agricultural University, Yi Zhu said that although African swine fever virus does not pose a health risk to people, pigs with African swine fever belong to sick pigs, and there is no reason to walk on the shelves and dining tables.

　　　　　　 What is African swine fever? It was diagnosed in Africa in 1921 and ravaged many countries in 2018.

　　　　　　 African swine fever is an acute and severe infectious disease of pigs infected by African swine fever virus. It was first diagnosed in Kenya in 1921, and it raged in many countries around the world in 2018. More than 6,200 outbreaks were reported in 22 countries. In August 2018, the first African swine fever epidemic occurred in Shenbei New District, Shenyang, Liaoning Province. Subsequently, epidemics also occurred in Zhengzhou, Henan Province, Lianyungang, Jiangsu Province, and Wenzhou, Zhejiang Province.

　　　　　　 According to the survey, there are three main transmission routes of African swine fever in China: the transportation of pigs and their products in different places, the feeding of kitchen waste to pigs and the spread of viruses carried by people and vehicles, accounting for 16.3%, 42.9% and 40.8% respectively. Among them, the spread of viruses carried by kitchen waste feeding pigs and personnel vehicles accounts for the vast majority.

　　　　　　 In January this year, the Ministry of Agriculture and Rural Affairs formulated and issued the "Emergency Implementation Plan for African Classical Swine Fever Epidemic (2019 Edition)" to guide all localities to deal with the epidemic in a strict and standardized manner. The Ministry of Agriculture and Rural Affairs said that the current epidemic situation in China is in a state of sporadic distribution, and the epidemic situation is generally controllable. However, because the traditional farming structure is difficult to fundamentally change in a short period of time, the transmission route of the epidemic is complicated, and the prevention and control situation is still complicated and severe.
