Experts respond to * prevention and control of African swine plague

The Information Office of the Ministry of agriculture and the rural * was released on the morning of November 23rd, and the Fangshan District pestilence situation was investigated in Fangshan District, Beijing. As of November 22nd, there were 73 pig farms and 1 wild boar outbreaks in 20 provinces and 47 municipalities (districts and * * *), killing 600 thousand massage
* the situation of African swine plague is highly concerned by the society. Why is the number of * African swine plague increasing in recent years? What are the challenges facing epidemic prevention and control? After the outbreak of swine fever in Africa, the Ministry of Agriculture and Rural Affairs has taken measures to restrict the transfer of pigs. How does this affect the current supply of pigs? Feng Zhongwu, deputy director of the Animal Husbandry and Veterinary Bureau of the Ministry of Agriculture and Rural Areas, and Huang Baoxuan, deputy director of the China Center for Animal Health and Epidemiology, gave an authoritative interpretation of these hot spots on May 23.male massage
In November 21st, after the discovery of * African swine plague in Fangshan District, Beijing, Beijing took positive and effective measures, resolutely resolutely disposed of and effectively controlled the epidemic according to the requirements of the emergency plan.
Up to now, 3337 pigs in Fangshan District have been killed and harmlessly disposed of within 3 km of the epidemic focus and radius. The entry and exit personnel and vehicles have been strictly disinfected. The outflow of pigs and pork products in the epidemic area has been strictly prohibited. The circulation of pigs and pork products in the threatened areas extending 10 km from the edge of the epidemic area has been strictly controlled.
The prevention and control of African swine fever is like a battle without smoke. The Ministry of agriculture and the rural areas strictly implemented the key measures such as epidemic investigation, extermination and elimination of * * *, prohibiting the use of leftovers from kitchen residues, feeding pigs, restricting the transportation of live pigs and their products in the epidemic areas, strengthening the supervision of pig transport vehicles, enhancing the ability and level of animal epidemic prevention at the grass-roots level, and resolutely disposed of the epidemic situation so as to prevent the spread and spread of the spa
"African swine fever is not a zoonotic disease, will not infect people, do not affect food safety." Feng Zhongwu said, "at present, the prevention and control work of African swine fever has achieved positive results. * the situation of African swine plague has shown a number of sporadic, stable, effective prevention and control and overall controllability. The data showed that the epidemic caused by feeding pigs with kitchen residues decreased from 50% to 34.3%, and the epidemic caused by pig transportation decreased from 35.3% to 19.4%.
Huang Baoxuan pointed out that African swine fever was introduced from abroad, and there was no African swine fever in China before 2018. Molecular epidemiological studies showed that African classical swine fever virus (CSFV) introduced into China belonged to genotype II, with 99.95% homology with the whole genome sequence of the strains published by Georgia, Russia and club
"Normally, there are four main ways of transnational import of African swine fever: international trade and smuggling of pigs and their products, pork and its products carried by international passengers, kitchen residues on international transport, and migration of wild boars." Huang Baoxu said that China has identified 68 outbreaks of swine flu * * and three main routes of transmission: one is the trans regional transport of live pigs and their products, accounting for about 19% of the total outbreaks *; two is feeding leftovers for pigs, accounting for about 34% of the total outbreaks, three of which are spread by personnel and vehicles, which is the most important way to spread the epidemic before. About 46% of the epidemic.
According to the news released by the Ministry of agriculture and rural *, every pig plague situation in China has been effectively disposed of. However, why is the number of * pestilence in Africa growing in recent years?
"The reason why the number of epidemics is still increasing is closely related to four factors." According to Feng Zhongwu's analysis, firstly, China has a long border, frequent international exchanges, and the risk of foreign epidemics continues to increase; secondly, African swine fever has obvious characteristics such as difficulty in early detection and prevention, and its latency period is long. After pig infection, it may not show clinical symptoms within three weeks, but the virus can not be transmitted by these during this period. The known diseases * pigs and their products are transmitted through various channels such as market transactions, slaughtering, personnel tools, long-distance transportation, contact transmission, food residue feeding and so on. Three, our residents are generally fond of hot and fresh meat, which has caused a large number of pig * s long-distance transportation. Meanwhile, the disinfection of vehicles and the management of brokers do not exist. Fourthly, there are a large number of small and medium-sized retail pig farmers in China. These retail pig farmers have poor biosafety conditions and have the habit of feeding pigs with food and kitchen residues, so the risk of introduction of the epidemic is high.
Feng Zhongwu pointed out that * from the external environment, the incidence of swine plague in Africa is frequent. Our country has frequent contacts with people in the epidemic areas, the volume of trade in goods is large, and the incubation period of African swine fever is long and concealment is strong, and the risk of re introduction is very high. According to the domestic situation, there are 26 million small-scale retail farmers in China. The backward breeding methods, the low level of biological safety protection, the unbalanced production and consumption of pigs in the region, and the long-term transportation of pigs and their products, all of these factors have greatly increased the difficulty of disease prevention and control.
"Recently, the number of epidemic provinces, especially the major producing provinces, is increasing. The task of prevention and control is still very arduous and urgent. It took other countries and regions five years to eradicate the epidemic, and even more than 30 years to eradicate it. We should fully understand the complexity and long-term nature of epidemic prevention and control. Feng Zhongwu said that under the premise of resolutely implementing the existing preventive and control measures and fighting hard battles against each epidemic situation, preparations should be made to cope with the more unfavorable situation and fight a protracted war.
After the outbreak of swine fever in Africa, the Ministry of Agriculture and Rural Affairs has taken measures to restrict the distribution of pigs and their products in epidemic areas. Some people worry that this will affect the production and supply of live sky massage
In this regard, Feng Zhongwu said that from the current situation, the pig production mode is actively adapting to restrictions on the transfer of measures, the national pig supply and price level is generally stable.
Feng Zhongwu said that from the production point of view, the first three quarters of the country
