Yunhai City, western suburbs.

Huangyang Village.

Huang Youfa's family, who live in the west of the village, run a pig farm.

The farm is neither large nor small, with more than 100 pigs at its peak.

Just after the end of the New Year, most of the pigs were sold, and now there are more than 80 pigs in the pen.

Huang Youfa is in his 40s, has a child who goes to college in the next province, and usually lives with his wife Zhang Xiaomi, as well as his old father Huang Jiye, and manages the pig farm together.

The sixteenth day of the first month.

Just after the Lantern Festival, visiting relatives and friends is basically over, and his son is about to start school, Huang You sent his son to the city train station, take the train to the next province to go to college, and when he came back, he bought some daily necessities by the way, and also went to the veterinary pharmacy to buy some commonly used veterinary drugs.

In the evening, return home.

His wife, Zhang Xiaomi, began to nag, "Why did you come back so late? My son is on the train at noon, and you have been walking around the city for an afternoon?"

Huang Youfa put a large bag of daily necessities in the living room, took out a black plastic bag from it, opened it, and inside was some dried grass leaves.

"Where am I idle? I sent my son away first, and then I went to the supermarket to buy these salted monosodium glutamate soy sauce, by the way, and the oyster sauce of your designated brand, and then went to the pharmacy next to the veterinarian station, which was recommended to me by the veterinarian in the traditional Chinese medicine. ”

"Do you want to take the Chinese medicine prescribed to you by the veterinarian?" asked his wife Zhang Xiaomi.

"Bah, this is for pigs!"

"Give the pigs Chinese medicine? Our pigs are not sick. ”

"The veterinarian said that this kind of traditional Chinese medicine is called cannon leaves, which is specially given to pigs to eat, to cure diseases, to prevent diseases, and to ensure that pigs eat to ensure that their stomachs are full of intestinal fat, fat and strong. ”

"How do you eat it? Feed the grass leaves directly to the pigs? That's a little bit. ”

"Just like people taking Chinese medicine, add water to boil, boil the juice, and then add it to the pig feed, you boil it out tonight, and tomorrow morning I will add it to the pig feed according to the proportion. ”

"Okay, just do as you say. ”

After dinner, Zhang Xiaomi put the cannon leaves into the pot and added water, and after boiling for half an hour, he put the medicinal juice into a large basin, and threw the remaining grass leaves into the trash.

1 a.m.

The old father was woken up by urine and got up in the middle of the night to go to the toilet.

When I came back from the toilet and passed by the kitchen, I found that there was a large basin of pale yellow and translucent water on the stove, and there were still a few leaves at the bottom of the water, which was very similar to the tea water I usually drink.

The old father took out a bowl and tasted it, slightly bitter.

"The taste of this herbal tea is strong enough, my daughter-in-law is really becoming more and more virtuous, and she also knows how to cook a big pot of herbal tea, and knows that it is greasy to eat during the New Year, so boil some herbal tea to remove the oil. ”

The old father drank two large bowls in a row, felt full and quenched his thirst, and then went back to the house to rest.

Half an hour later.

He felt very unwell, nauseous and wanted to throw up.

I struggled to reach out and turn on the bedside lamp, only to find that everything in the room was ghosted, my eyes couldn't see clearly, and my head hurt badly.

There was a tumult in the stomach, and a large amount of stomach contents were vomited, and the bed and floor were everywhere.

He wanted to get up and go out and call for help, but he was trembling.

Reluctantly crawled to the edge of the bed, tried to stand up but fell to the ground.

His face was pale, his lips and limbs began to turn purple, his pupils on both sides slowly dilated, his breathing slowed down, and he finally lost his reaction.

At 6 a.m., the sky was slightly bright.

Huang Youxian launched the bed to prepare to feed the pigs.

Put on his coat, first go to the warehouse to get pig food, prepare to boil pig food, pass by the door of the old father's bedroom, and find that the light is on inside.

Father got up?

According to the past practice, Huang Youfa is the earliest in the family, get up at dawn to boil pig food first, and after boiling pig food, his father will get up and help start feeding the pigs, why did he get up so early today?

"Dad, why do you get up so early? It's not dawn yet, you can sleep a little longer, I'll just boil pig food." ”

There was no response from the house, and the bedroom door was ajar, and there was a sour smell coming from the crack in the door.

Doesn't that smell right?

It's like the sour taste of the stomach when a person vomits.

Huang Youfa chuckled in his heart, could it be that his old father was sick.

Pushing the door open, he was stunned by what he saw.

The old father was lying on his back on the ground, and there was yellow-brown vomit all over the bed and on the floor.

"Dad, what's wrong with you?"

Huang Youfa rushed forward, but found that the old father on the ground had his eyes closed and his face was blue.

Fingers are put under the nose and there is no breath.

When you touch your body again, your body temperature is cold and your muscles stiffen.

They have been dead for a long time.

Huang Youfa was so sad that he sat down on the ground and came back to his senses for a while before he cried loudly.

The cry attracted his wife Zhang Xiaomi, who was shocked and frightened when she saw this.

My father-in-law is usually in good health, so why do you say that he dies?

And the death was miserable, his face was blue, and he vomited a lot of things before he died, which made the bed and the floor everywhere, isn't it food poisoning?

But my father-in-law usually eats in the same pot with them, if my father-in-law has something, why is he okay?

No matter what the cause of death is, now that people are dead, the most important thing is to do the funeral quickly.

According to the customs of Huangyang Village, when an elderly person dies in the family, relatives and neighbors will come to help.

After the funeral, dozens of relatives and neighbors came to help.

Now go to the city to buy a shroud coffin and contact the funeral home.

By the time the ashes were brought back, it was already afternoon.

According to the custom, a flowing water banquet is set up to entertain relatives and friends who come to attend the funeral.

The flowing water mat started at 4 p.m., and after eating for more than half an hour, some people began to feel uncomfortable before they finished eating.

"Yes, my stomach hurts. ”

"I also have a stomachache. ”

"I felt nauseous and couldn't breathe. ”

"Me too, it's uncomfortable. ”

......

Several tables of guests had symptoms.

Huang Youfa and his wife Zhang Xiaomi panicked, could it be that there is a problem with the food?

"Everyone, don't eat, hurry, go to the hospital. ”

People who had no symptoms started calling 120 for an ambulance, and had a clear mind and decided to drive their car to the nearest hospital.

On the way to the hospital, someone couldn't stand it and was out of breath.

The office phone rang on Li Bai's desk.

Picking up the phone, it was a familiar male voice.

"Director Li of the CDC? I am Gao Xiaoming from the emergency department of the People's Hospital, and we have just received more than a dozen food poisoning patients in the emergency department, and the cause of the poisoning is currently unknown, and we need your CDC's assistance in the investigation. ”

Gao Xiaoming is the director of the emergency department of the First People's Hospital of Yunhai City, and he has had business contact with Li Bai before, so Li Bai remembers his voice.

"What is the number of poisoners?

"At present, there are 11 people who have been sent to the hospital, all of whom are from Huangyang Village in the western suburbs, all of whom became ill while attending a funeral dinner, and developed symptoms within half an hour after the dinner, and the symptoms are mainly nausea and vomiting, eye vision disorders, body cyanosis and other hypoxic symptoms. ”

"Okay, I'll take someone over now. ”

Hanging up the phone, Li Bai stood up, "Let's stop what we're doing first, there is a public health emergency, and the People's Hospital has received a suspected collective food poisoning incident, which needs to be dealt with." ”

Most of the emergency incidents in the CDC are food poisoning, whether microbial or chemical, and they are very experienced in dealing with them.

The members of the emergency response team immediately prepared their things and went to the scene.
