Grandma Li's symptoms were relatively mild, and she hurriedly replied: "I made a total of four dishes and one soup, roasted pork ribs with potatoes, braised large yellow croaker, three fresh potatoes made of eggplant and green peppers, fried flower nails, and a sea oyster tofu soup." ”

Dinner is really hearty, fish, seafood, and vegetables are all available.

"Who was the first to show symptoms? Approximately how long after dinner do symptoms appear? Lu Li asked.

Grandpa Li: "Me! My first symptoms were an itchy throat, followed by dizziness and stomach aches. ”

"What did you have for dinner?" Lu Li asked.

"I ate a little bit of everything."

It was supposed to be a problem with dinner, but I couldn't be sure what was wrong.

——

10:10 a.m.

Dongcheng District, Yanhe Community.

The home of Grandpa and Grandma Li.

Because they had already received the keys to the house from Grandma Li in the community hospital, accompanied by community personnel, Gu Yanan and other disease control team successfully entered their home.

Typical 3 bedrooms and 2 living rooms, a family of 5 layout.

Because of the obvious purpose of this on-site flow survey, Gu Yanan carried the sampling box and went directly to the kitchen.

The leftovers from last night were still in the refrigerator, Gu Yanan opened the refrigerator, took out all the meals one by one, picked up the representative ones and put them into the sampling bag, sealed them, and put them in the sampling box.

Lu left the bathroom to look for uncleaned vomit, which is the focus of laboratory testing.

After cleaning up the food in the refrigerator, Gu Yanan began to rummage through the garbage in the kitchen that had not been thrown away.

Rotten vegetable leaves, fish offal, and potato skins......

Gu Yanan picked up the potato skin with tweezers, and his heart trembled.

This is different from the normal potato skin, the potato skin in this trash can has a lot of slender sprouts, and the potato skin is already blue.

Green potatoes and sprouted potatoes are inedible, looking at the appearance in the trash can, the potatoes that Grandma Li's family ate last night were sprouted potatoes.

Sprouted potatoes contain high amounts of solanine.

If the human body ingests excessive amounts of solanine, it will cause symptoms of itchy throat, dizziness, abdominal pain and diarrhea, which is the same as the symptoms of grandma's family of 5 and poisoned students in Dongcheng District's college town.

After Gu Yanan stuffed the potato skins in the trash can into the sampling bag, he immediately called Section Chief Li of the laboratory.

"Li Ke, there are new clues, testing for solanine, especially for dishes with potato ingredients."

"Director Gu, do you suspect that the students ate sprouted or green potatoes and were poisoned with solanine?" Section Chief Li on the other end of the phone asked in surprise.

"Well, I found sprouted potato skins at the home of a newly reported food poisoning epidemic patient, and the symptoms of these two food poisoning patients are the same, and after the previous investigation, I found that there are potatoes in many dishes in the problem cafeteria in the university town of Dongcheng District, especially the free soup is also made of potatoes, so I suspect that the students were poisoned because they ate this potato containing solanine."

"Understood, I'll start checking solanine right away, and I'll tell you when I get the results."

——

1:20 p.m. on the same day.

Gu Yanan and Lu Li returned to the problem cafeteria in the university town of Dongcheng District for a second transfer.

A large number of uneaten sprouted potatoes were found in the warehouse of the cafeteria in question.

At the same time, Section Chief Li of the CDC also reported the test results of the physical and chemical group.

In the samples collected from the canteen in question, solanine was detected in several dishes containing potatoes, such as potato roast pork and potato leek soup.

Solatene was also detected in the vomit and blood of the poisoned students.

Solatelin was detected in the vomit of a poisoned family of five in Yanhe Community, Dongcheng District, and in the potatoes left over from dinner.

Gu Yanan contacted the school leaders, found the contractor of the cafeteria, and found out the source of the problematic potatoes from the contractor.

It turned out that the contractor had purchased a large number of sprouted potatoes from a wet market at a low price in order to save costs.

Grandma Li's family also bought sprouted potatoes from the same vegetable market.

The source of the two cases of food poisoning was identified, and Gu Yanan promptly fed back the test results and flow survey results from the laboratory to the community hospital and the First People's Hospital, and the clinicians began treatment according to the method of solanine poisoning, and the poisoned patients were discharged one after another.

——

A few days later.

Lianhai Center for Disease Control and Prevention, Emergency Office.

Gu Yanan is writing a summary report on the food poisoning of a family of five in the university town and Yanhe community in Dongcheng District.

The plague level 1 response is over, and schools are opening one after another.

In order to save costs, a canteen contractor in a university town in Dongcheng District purchased a batch of sprouted potatoes from the vegetable market.

The sprouted potatoes are simply peeled and then served as a dish for students in university towns.

Sprouted potatoes contain a large amount of solanine, and after eating them, students experienced symptoms of solanine poisoning such as sore throat, dizziness, abdominal pain, diarrhea, nausea and vomiting.

One of the students developed severe symptoms 15 minutes after eating due to overdose, and died in the school medical office.

The remaining poisoned students were sent to the First People's Hospital and Dongcheng District Community Hospital for treatment.

Grandma Li's family in Binhe Community bought the same batch of sprout potatoes in the same vegetable market, and they also had symptoms of solanine poisoning after eating them that night.

After treatment, the poisoned student and Grandma Li's family were discharged from the hospital one after another.

After writing the summary report, Gu Yanan was preparing to file the report.

Wang Xiaoxiao looked at Gu Yanan and asked, "Sister Yanan, this time the food poisoning in the University Town of Dongcheng District and the food poisoning of Grandma Li's family in Yanhe Community have been dealt with together?" ”

"Well, the source of the poisoning in the two poisoning incidents is the same, both because they bought and ate the same batch of sprout potatoes from the same vegetable farm."

Lu Li: "The vendor who sells sprouted potatoes must not only sell to the problem canteen and Grandma Li's family in the university town of Dongcheng District, there must be other customers who have bought them, I don't know if these sprouted potatoes eaten by other people have any symptoms of poisoning?" ”

Wang Xiaoxiao: "If there is no report on the epidemic system, then there should be none." ”

Gu Yanan: "Solanine poisoning according to the amount of intake of the symptoms are mild and severe, the symptoms are mild as long as a little recuperation, many people are not aware of solanine poisoning, and they will not even go to the hospital for treatment, and the attending doctor has limited understanding of this aspect, so as long as it is not a cluster of severe cases, it is normal for the epidemic to be reported on the Internet." ”

Wang Xiaoxiao sighed: "The summary report of this food poisoning has been written, and the epidemic has finally passed, Sister Yanan, I want to take a day off tomorrow." ”

"Yes." Gu Yanan happily agreed.

Lu Li reminded with a smile: "The last plague epidemic was also after writing a summary report, and there was a big aftermath like Li Tianlong. ”

"Bah, blah, bad spirits, bad spirits. Lu Li, don't talk nonsense with your crow's mouth, the aftermath of the plague Li Tianlong This matter has ended, and the food poisoning is not contagious, so there is no such thing as aftermath. ”

Zhou Lao: "Xiaoxiao, don't worry, now our monitoring system is very strict, even if there is an aftermath, it will be controlled in time, you want to take a break and go to play with peace of mind." ”

Wang smiled bitterly, "I don't want to play, I just want to go home and catch up on sleep." ”
