The occurrence of African swine fever in Tengchong, Yunnan Province has been blocked, culled and harmless
Xinhua news agency, Beijing, November 13 - the Information Office of the Ministry of agriculture and rural areas released a news on the 13th that an African swine plague occurred in Tengchong City, Yunnan Province.
On November 13, the Ministry of agriculture and rural areas received a report from the China animal disease prevention and control center, which confirmed that an African pig plague occurred in a farmer in Jietou Town, Tengchong city.
At the time of the outbreak, the farmer kept 261 pigs, 177 were sick and 97 died.
After the outbreak, the Ministry of agriculture and rural areas immediately sent a steering group to the local area to carry out epidemic disposal supervision and epidemiological investigation.
The local government has started the emergency response mechanism as required, taken measures such as blockade, culling, harmless treatment and disinfection, and culled the remaining live pigs in the epidemic area, and culled the live pigs and all dead pigs for harmless treatment.
At the same time, all pigs and their products are prohibited from being transferred out of the blockade area, and pigs are prohibited from being transported into the blockade area.
At present, the above measures have been implemented.
Tengchong is subordinate to Yunnan Province. In November 2017, it won the honorary title of the fifth national civilized city. In January 2019, Tengchong city was recognized as the advantageous area of agricultural products with Chinese characteristics.
Tengchong is located in the west of Yunnan Province. Tengchong has a tropical monsoon climate, integrating the advantages of continental climate and marine climate. It has sunny weather in winter and spring, warm climate, sunny and rainy in summer and autumn, and cool and pleasant climate.
Tengchong has a wide variety of mineral resources with high grade. It is one of the rich mineral counties in Yunnan Province.
The water resources in Tengchong mainly include three major water systems: betelnut River, Longchuan River and Daying river. The water energy reserve is more than 1.3 million kilowatts, and the overall development is under way.
Tengchong is China's first Emerald City, China's top tourist County, China's top ten most attractive scenic spots, China's major cultural tourism County, China's best cultural ecotourism destination, China's top 10 most beautiful scenic counties in Yunnan, the most beautiful cultural tourism and leisure County, and the world's best ecotourism destination. The '2018 list of China's most beautiful counties' was released and Tengchong was listed.
The African swine plague occurred in Jietou Town, Tengchong City, in the north of Tengchong City, Yunnan Province, near the China Myanmar border.
According to public information, Jietou town is about 40 kilometers away from banwa town in Myanmar.
How to effectively prevent African classical swine fever
1. Keep the enclosure clean
Farmers shall clean up the manure pile in time every day. The pig house shall be kept clean, dry, ventilated, warm and appropriate feeding density to create a suitable environment for pigs. Farmers should disinfect the cages, pens and pigs at least once a week, and choose a kind of low toxicity disinfectant with strong bactericidal power to be used in turn to prevent the emergence of drug resistance.
2. Improve pig immunity
Improving the immunity of pigs is an effective way to prevent classical swine fever. In the process of daily feeding, some agents that can improve immunity should be added to the feed. At the same time, allowing pigs to properly participate in outdoor sports can enhance their metabolism, tighten their muscles, promote appetite and enhance their physique.
Let's talk about African swine fever
African swine fever (ASF) is an acute, hemorrhagic and severe infectious disease caused by African swine fever virus (ASFV) infecting domestic pigs and various wild pigs (African wild boar, European wild boar, etc.). The world organization for animal health (OIE) lists it as a legally reported animal epidemic disease, which is also a kind of animal epidemic situation that countries focus on preventing.
The disease was first reported in Kenya in 1909 and has existed in sub Saharan African countries. In 1957, it spread to Western European and Latin American countries, and most of them were extinguished in time. However, it is still prevalent in Portugal, southwest Spain and Sardinia, Italy.
The virus can be confirmed from the blood, tissue fluid, internal organs and other excreta of infected pigs. The virus in the blood in the low-temperature dark room can survive for six years and live for several weeks at room temperature. When the blood infected by the virus is heated at 55 ℃ for 30 minutes or 60 ℃ for 10 minutes, the virus will be broken, and many fat solvents and disinfectants can destroy it.
The incubation period of natural infection is 5 ~ 9 days, which is often shorter. The clinical experimental infection is 2 ~ 5 days. The body temperature rises to 41 ℃ at the onset and lasts for about four days. It is characterized by the decrease of body temperature 48 hours before death.
Before 2018, there was no African swine fever in China. Molecular epidemiological studies show that African classical swine fever virus introduced into China belongs to genotype II, and the homology of the whole genome sequence with the strains published in Georgia, Russia and Poland is about 99.95%.
There are three main ways of transmission of the 68 swine epidemics that have been identified in China: first, cross regional transportation of live pigs and their products, accounting for about 19% of the total epidemic; Second, feed pigs with kitchen residues, accounting for about 34% of the total epidemic situation; Third, people and vehicles carry virus, which is the main way of epidemic spread, accounting for about 46% of the total epidemic.
African swine fever only infects pigs but not people
African swine fever is not a 'zoonosis' and does not infect people, but it is very fatal to pigs.
African pig plague needs the attention of agricultural departments and farmers, but consumers should eat and drink. Don't worry.
Xinhua reported: 'African classical swine fever does not infect people and has no direct impact on human health and food safety.
From the research situation, it is unlikely that mutation will infect people. " The head of the animal husbandry and Veterinary Bureau of the Ministry of agriculture and rural areas said that the pork and products purchased through formal channels have been quarantined, and the public need not worry.
To sum up, don't worry. African classical swine fever is harmless to people. Consumers don't worry about eating and drinking.
Moreover, many African swine epidemics have occurred in China, and they have been effectively controlled and eliminated every time.
Therefore, there is no need to worry about the large-scale development of African pig plague, which will lead to the death of pigs and the soaring price of pork.
Because the news has just been released, the rise in pork price is only temporary. I believe that the price will be rational and stable soon.
