Chapter 1466: Total Fall

If it's just two middle-aged and elderly women talking about the housework, Zhang Zian doesn't bother to listen, how boring must he be to listen to those gossips? But the middle-aged woman who came in later mentioned the CDC, which made him pay attention.

"CDC...Where is it?"

The old lady who speaks 6 Cantonese is at a loss. She may be the type of immigrant who has lived in China for most of her life, and her children took her over to reunite with the family after their children settled down in the United States. It may change their lifestyle for most of their lives, and it is unlikely to learn a new language.

But it’s really nothing, even if you don’t know a single English letter, Chinatown can fully meet all your daily needs, whether it’s food, clothing, clothing, legal or illegal, you can find it here, almost A country within a country, as long as there is no need to drive, it is completely OK.

Like this old lady, after immigrating to the United States, her lifestyle is no different from that in China. She buys vegetables, cooks, walks and plays mahjong, and watches Chinese TV programs. She spends 99% of her time in Chinatown. Turning a blind eye to it, just pretending it doesn't exist, let alone caring about the news of the outside world. As long as there is no global war, the peaceful daily life will continue until the end of her life.

When she heard the word CDC, she had no idea what it was.

"Grandma, you don't know yet? CDC is the Centers for Disease Control and Prevention in the United States. A while ago, some doctor was interviewed on TV, saying that there is a disease spreading to deer in North America, and this disease is still It may infect people! It is said that if you eat venison, it is best to eat venison that has passed the quarantine from formal channels." The middle-aged woman explained patiently.

"Hey, so powerful? Is it like that, bird flu?" The old lady was dubious, looked at the middle-aged woman, and then looked back at the venison, still a little bit reluctant.

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

"This... Eldest sister, I accidentally heard you guys talking just now, what's wrong with the deer?"

Zhang Zian interjected cheekily.

The middle-aged woman took a look at him and saw that he didn't look like a suspicious person wanted by the Department of Homeland Security, nor did he look like a shop assistant. She was also Chinese and looked friendly, so she replied: "I can't remember the exact name. You can find it from the Internet." You can find out whether it’s called emaciation disease or diabetes disease.”

"Oh, thank you." He thanked, and stepped back into the corner to show that he would no longer listen to the conversation between the two.

The middle-aged woman continued to persuade the old lady not to buy venison.

Diabetes is definitely wrong,

He took out his mobile phone and searched for keywords of "wasting disease + deer".

I don’t know if I don’t look at it, but I’m startled when I see it.

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

He was very busy a while ago, whether it was a trip to Egypt or a pest plague, or the stray dogs behind him picking up waste, he didn't have the time and leisure to pay attention to the news on the other side of the ocean. After all, there are 24 hours a day, and if he has spare time to pay attention to local and domestic news in Binhai Not bad.

He searched for the relevant reports, and simply browsed through them without going into too much detail. After all, this is a butcher shop with people coming and going, but after reading it, his heart suddenly became clear, and many lingering mysteries finally revealed a corner of the answer.

The so-called deer wasting disease, referred to as CWD, is a disease very similar to mad cow disease. Because it is mainly transmitted on deer, it is called mad deer disease by some people, because the deer will be as aggressive as rabies in the later stage of the disease. Because the sick deer moves and looks like zombies in movies, it is called zombie deer by the public.

The culprit of wild deer disease is not an ordinary virus or bacteria, but a kind of prion protein. As long as it comes into contact with normal protein in the organism, it can cause the normal protein to change its structure and convert into prion protein.

The most painful thing is that this prion protein is extremely tenacious, like an invincible Xiaoqiang, which cannot be killed by a high temperature of 100 degrees Celsius. It is also resistant to radiation and ultraviolet rays, and is extremely resistant to common disinfectants. .

As long as you are infected by this prion protein, there is currently no drug that can reverse the disease.

As of January 2019, wild deer disease has been reported in 24 states in the continental United States and two provinces in Canada. You must know that there are only 48 states in the continental United States, that is, half of the United States has been attacked by wild deer disease.

Not only that, mad deer disease has spread out of North America, and cases have also been found in reindeer and moose in Norway and Finland, and even South Korea, which imports a large amount of deer antler, has also been affected. Fortunately, these three countries are limited in size, unlike the United States, which has millions of square kilometers of land to toss around.

Some species of deer are accustomed to long-distance migration. For example, tens of thousands of wild reindeer in Nunavut, Canada, will periodically migrate under the guidance of wolves, which makes 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, and the forest parks are often very close to each other, or even connected together. The deer can migrate from one park to another without anyone noticing.

What's more troubling is that mad cow disease and wild deer disease are just two of the many masterpieces of prion protein, in addition to sheep scrapie, ferret transmissible encephalopathy, and feline spongiform encephalopathy, which are collectively referred to as infectious diseases. Spongiform encephalopathy.

Several similar diseases have also been found in the human population, including human mad cow disease transmitted from sick cows to humans. Related studies have shown that wild deer disease of a similar nature can infect primates, such as monkeys, and theoretically humans can also Infected, but no cases of human infection with wild deer disease have been found so far.

The super vitality of prion protein makes it resistant to conventional disinfection methods such as high-temperature cooking. The temperature of cooking and stewing at home is absolutely impossible to kill prion protein.

The spread of mad cow disease back then was caused by feed manufacturers feeding the meat, brain, and viscera of diseased cattle to normal cattle. The disinfection methods in the feed processing process also failed to kill prions.

The doubts in his mind were finally connected to each other slowly. The unknown meat powder in that Le Shi dog food... maybe it was made of venison, right?

High-priced venison is impossible, and the cost must be kept down. It is likely to be high-risk deer brains, internal organs, and bones that contain spinal cords.

As for why the manufacturer dared to do this... I can only guess that it is because the scientific community has not yet discovered transmissible spongiform encephalopathy in dogs, so the manufacturer believes that it is no problem to make venison into dog food and feed it to dogs.

But if something has not been discovered, must it not exist?

If sheep, cows, cats, ferrets, monkeys, humans, and other animals that are not related to horses and cattle can be infected, can dogs and coyotes, such as canids, be able to survive alone?
