Why test for African swine fever and what is the significance of testing

Since 2019, pork ** has soared all the way until about 30 yuan a catty, which is not a small increase compared with before, why is there such a big increase?

1. In the case of imported soybeans and corn, the cost of breeding is high, and no farmers are willing to breed, if you add the cost of other veterinary drug vaccines, the cost of buying piglets, and the cost of raising sows and labor costs.

Wait. 2.For domestic pork** soaring, in order to allow the people to eat cheap pork, the import of frozen meat will also be increased in 2020.

3.African swine fever.

Virus, there is a very good saying in the ancient book, that is, "success is also Xiao He defeat is also Xiao" non-plague has caused the slaughter of pigs to drop by 1 3Therefore, the detection of African swine fever virus is an important measure for the prevention and control of African swine fever, which is of great significance. In order to further improve the accuracy of African swine fever virus detection results and standardize the production, operation and use of African swine fever virus diagnostic products, from January 1, 2021, all relevant departments and units shall use the African swine fever virus test for pigs and their products in animal quarantine or disease monitoring and diagnosis, and shall use the African swine fever virus that has been obtained by the Ministry of Agriculture and Rural Affairs.

The product approval number issued.

African swine fever virus diagnostic products to ensure accurate test results.

The JD-PCR African Swine Fever PCR Detector can quantitatively and rapidly diagnose animal husbandry diseases, such as African swine fever and avian influenza.

Swine fever, porcine blue ear, pseudorabies and other diseases are widely used in farms, slaughterhouses, food processing plants, meat product deep processing enterprises, the Ministry of Agriculture and Rural Affairs, Animal Husbandry Bureau, inspection and quarantine units.

For the sake of pork, **not**, for the money in our pockets that we can afford to buy pork, for the sake of us to still eat meat.

In order to protect the safety of the tip of the tongue and avoid uncontrollable situations, the detection of African swine fever can reduce the losses of farmers.

Detect African swine fever and prevent it in time to avoid greater losses for individual farmers in pig farms, slaughterhouses, and slaughterhouses!

African swine fever is mainly transmitted through contact, and pigs do not spread to humans. If you think about it, if you are not a Muslim or a type of person who does not eat pork, then there is a high chance that you will eat pork, and if you do not test for swine fever, then you may eat pork with swine fever, and then infect yourself and others. The meaning of testing is not to let you be infected and not to cause a huge disaster to the world.

Because of the high lethality of swine fever and the high infection rate, once a pig is infected with African swine fever, the pigs of the entire pig farm must be culled, which is a devastating economic blow to the average farmer. The detection of African swine fever is to find the pigs infected with swine fever before the onset of the disease, dispose of them in time, stop the loss in time, and the effect of blood testing on the market is lower than that of saliva detection.

For the sake of national safety, the meaning is to be able to save your life!

For the sake of life, it's not for your own good.

It can be detected with an instrument, the African swine fever detector (Jingdao brand) is very accurate, using the method of real-time fluorescence quantitative PCR analysis, the detection time is short, the detection efficiency is high, the detection speed is also very fast, and it meets the requirements and standards of the national food safety supervision and management department, and can be used with confidence.

Summary. Quality control standards.

1) The CT value of the negative control should be 38 or no CT value.

2) The CT value of the positive control should be 35 with a typical amplification curve.

How many people tested positive for African swine fever.

Quality control criteria: 1) The CT value of the negative control should be 38 or no CT value. 2) The CT value of the positive pair should be 35 and a typical amplification curve should appear.

Tested positive yesterday and didn't take any measures, what's the deal with being negative today?

Suspicious: The 35 ct value of the test sample and Pie is difficult to talk about 38, and there is a typical amplification curve with sheds, it should be retested, and the retest is still judged to be positive if the above results are still present, otherwise it is judged to be negative.

How do you eliminate the virus from people?

When the temperature reaches 55 for 30 minutes or 60 for 10 minutes, the ASF virus can be killed.

Is bathing also eliminating?

Can clothes be eliminated by soaking them in water at high temperatures?

Right. Okay thank you.

With an African swine fever test report, the testing proportion shall not be less than 30% What is the sampling ratio of African swine fever? - The sampling ratio of African swine fever is generally 1:20, well, this ratio should still be okay.

Is it serious. The DNA ends of African swine fever virus (ASFV) are cross-linked, and the virion has a DNA-dependent RNA polymerase. After the growth and adaptation of monocytes in pigs, they can multiply in a variety of cells, and the Vero cell line is commonly used to culture the virus. Virions are erythrocyte adsorbent.

There are at least 8 serotypes in Africa and one in Europe. Due to virus mutations, many subclinical chronic cases have emerged. The symptoms of African swine fever resemble those of classical swine fever, but there is no serologic relationship between the two.

Infected pigs carry the virus for a long time. There is no good vaccine to prevent the disease. It is found in Africa, southern Europe, Western Europe, Cuba, and Central America.

Seriously. You're sick.

Or the sampling ratio.

As long as you get it, it's very serious.

It was to draw a pig's blood and test it.

Tell me, I don't understand either.

How many pigs were smoked?

Does he know your total number of pigs?

Just one. It has to do with a few pigs.

That's fine. Don't worry ha.

Let me sell it.,Other pigs are fine.,As soon as I said the value, I was frightened.,I don't understand.,Just ask the teacher.。

- The sampling ratio of African swine fever is generally 1:20, well, this ratio should still be okay.

Yours say it's okay.

The following symptoms can be compared to determine whether the pig is suffering from African swine fever.

1. When the sick pig begins to have a fever, the body temperature will reach about 40-42 °C, and it will be red, conjunctival flushing, hyperemia, body surface bleeding, blood stasis, listlessness, and the symptoms of the lower abdomen, limbs, buttocks and other parts of the sick pig will be particularly serious.

2. Sick pigs will also have panting, coughing, dyspnea, lymph nodes, gastrointestinal mucosa, and kidney bleeding. Moreover, there is a decrease in appetite or even abolition, dry and hard feces, or constipation, purulent blood feces, and the eyes and nose of sick pigs will have serous and mucus substances flowing out.

3. When the sow is infected, there will be infertility, abortion and even stillbirth, etc., after the death of the sick pig, the autopsy can find that the lungs, liver, spleen and other organs and lymph nodes are seriously enlarged, and there is generally bleeding, stasis, etc.

4. In the case of acute onset, the mortality rate of this disease is very high, especially sows and large pigs will die quickly.

How to deal with African swine fever in pigs

If pigs suffer from African swine fever, it generally cannot be effective, because African swine fever is a very contagious disease, and it must be reported to the local authorities as soon as it is found. Generally, after being confirmed to be infected with African swine fever, the superior department will send professional personnel to isolate the sick pigs, or cull and destroy them. Pig farms must do a good job of disinfection, because the final result of pigs infected with African swine fever is death, so it must not be handled without authorization.

<> the pre-symptoms of African swine fever are not obvious, they can be detected by a PCR analyzer. First of all, take about 5 milliliters of live pig blood or meat products, pig slaughtering line sewage, slaughtering utensils scraping, etc., put them into sterilized centrifuge tubes, mix well, take the supernatant, and then put them into 20 ml of PCR reaction solution.
