If only two middle-aged and elderly women pull home, Zhang Zi'an is too lazy to listen, and how busy are they to be bored before listening to the short gossips of their parents? But the middle-aged woman mentioned later mentioned the CDC, which made him stay in God.

"CDC ... Where is it?"

An old lady who speaks Cantonese 6 is bewildered. She may be the type of immigrant who lived in the country for the majority of her life and her children took root in the United States to reunite with her family. Older immigrants like this age are not It may change their lifestyle for most of their lives, and it is unlikely that they will learn a new language.

But in fact, there is nothing. Even if you do n’t know an English letter, Chinatown can fully meet all the needs of life. Whether it is food, used, worn, legal or illegal, you can find it here, almost A country within a country is completely OK as long as there is no need to drive.

Like this old lady, after immigrating to the United States, the lifestyle is no different from that in the country. Shopping for food, cooking and playing mahjong, watching Chinese TV programs, 99% of the time are mixed in Chinatown. For the English world outside Ignoring it, when she doesn't exist, she doesn't care about the news of the outside world. As long as there is no global war, the peaceful daily life will continue until her end of life.

When she heard the word CDC, she didn't understand what it was.

"Aunt, don't you know? CDC is the Centers for Disease Control and Prevention in the United States. Some doctor who was interviewed on TV recently said that there is any disease spreading in deer in North America. It may be transmitted to people! It is said that if you eat venison, it is best to eat venison from regular channels. "The middle-aged woman explained patiently.

"Yo, so terrible? Is it like that, bird flu?" The old lady was dubious, looked at the middle-aged woman, and looked back at the venison again.

The middle-aged woman spoke Mandarin, and the old lady followed her to speak Mandarin Cantonese.

"This ... eldest sister, I just accidentally heard you say, what's wrong with the deer?"

Zhang Zi'an interjected cheekily.

The middle-aged woman glanced at him, seeing that he did not look like a suspicious character wanted by the Homeland Security Bureau, nor did he look like a clerk. The Chinese also looked kindly, so he replied: "I ca n’t remember the specific name. You can find out what it is called wasting disease or thirst. "

"Oh, thank you." He thanked him and stepped back into the corner to show that he was no longer listening to the conversation.

Middle-aged women continue to persuade old ladies not to buy venison.

The thirst disease is definitely not right. He took out his mobile phone and searched for the keyword "wasting disease + deer".

I do n’t know, I was shocked at first glance.

Since when did the North American continent quietly begin to spread the disease?

A while ago, he was very busy. No matter it was a trip to Egypt or a pest disaster, or stray dogs in the back, there was no time and leisure to follow the news on the other side of the ocean. After all, there are 24 hours a day. That's great.

He searched for relevant reports and simply browsed it without looking too detailed. After all, this was a butcher shop where people came and went, but after reading it, his heart suddenly opened up, and many mysteries lingering in his heart finally revealed a corner of the mystery.

The so-called deer wasting disease, referred to as CWD, is a disease very similar to Mad Cow Disease, because it is currently mainly spread on deer and is called rabies by some people, because deer will be as aggressive as rabies in the later stages of disease. Sex, because the sick deer moves and looks like a zombie in the movie, they are called zombie deer.

The culprit of rabies disease is not an ordinary virus or bacteria, but a prion protein. As long as it contacts normal proteins in the body, it can cause normal protein to deform and convert to prion protein.

The most painful thing is that this kind of prion protein is extremely tenacious, like Xiaoqiang who can't be killed, it can not be killed by the high temperature of 100 degrees Celsius, and it is also resistant to radiation and ultraviolet rays, and has strong resistance to common disinfectants. .

As long as it is infected with this prion protein, there is currently no medicine that can reverse the condition.

As of January 2019, 24 states in the United States and two provinces in Canada have reported the discovery of rabies. There are only 48 states in the United States. That is, half of the United States has been captured by rabies.

Not only that, but the disease has spread to North America. Cases have also been found on reindeer and moose in Norway and Finland, and even South Korea, which imported a large amount of antler, has been affected. Fortunately, these three countries have limited areas, unlike the United States, which has millions of square kilometers of land to toss.

Some species of deer are accustomed to long-distance migration. For example, thousands of wild reindeer in the Nunavut region of Canada will periodically migrate along with the wolves, making the control of wild deer disease extremely difficult.

There are too many forest parks in the United States that are suitable for the survival and reproduction of deer herds, and forest parks are often very close to each other, or even connected together. Deer herds can migrate from one park to another without knowing it.

Even more annoying is that mad cow disease and stag disease are only two of the many masterpieces of prion protein, in addition to sheep pruritus, ferret infectious encephalopathy, and cat spongiform encephalopathy. These animal diseases are collectively referred to as infectious Spongiform encephalopathy.

Several similar diseases have been found in the human group, including human mad cow disease transmitted from diseased cattle to humans. Related studies have shown that similar deer diseases can infect primates, such as monkeys. In theory, humans can also Infected, but no human cases have been identified.

The super vitality of prion protein ~ lightnovelpub.net ~ makes it resistant to conventional disinfection methods such as high temperature cooking. It is impossible to kill prion protein at home with the temperature of rice stew.

The spread of mad cow disease that year was caused by feed manufacturers feeding the meat, brain, and internal organs of diseased cattle to normal cattle, and the disinfection methods in the feed processing process also failed to kill prion protein.

The doubts in his heart were finally connected to each other. The meat powder of unknown Leshi dog food was made of venison.

High-priced venison is impossible, and it must be kept at a low cost. It is likely to be a powder made of high-risk deer brain, internal organs and bones containing spinal cord.

As for why the manufacturers dare to do this ... I can only guess, because the infectious spongiform encephalopathy of dogs has not been found in the scientific community at present, so the manufacturers think that it is no problem to feed venison into dog food.

But if something is not found, it must not exist?

If sheep, cows, cats, ferrets, monkeys, and humans, these uninformed animals may be infected, can dogs such as dogs and coyotes be able to survive alone?
