The police came one step ahead of the city's disease control people.

Section Chief Qian of Xicheng District Disease Control and Prevention also saw Gu Yanan and his party hurriedly greeted him in the shop, picked up the cordon and let them go, and said: "Director Gu, you are here, the police are questioning the store owner here, because the first deceased of food poisoning died directly in the store, so the forensic doctor also came." ”

If there are deceased people in the epidemic and the police intervene in the investigation, it will be a little troublesome to do another investigation, because it is necessary to ensure that the police collect evidence first, so Gu Yanan instructed Lu Li, who was following behind, "Don't destroy the scene first, I will communicate with the police first, and then take samples." ”

Entering the small shop, the deceased was still lying on the ground, with various marks around him, and the forensic doctor was doing a scene survey, and several young policemen were questioning the shopkeeper on the side, and the shopkeeper looked flustered and could not answer.

Gu Yanan tried to find a familiar figure from this group of policemen, and soon she saw the policeman Xiao Li coming out of the back kitchen, followed by Xiao Li was Nan Hanfei.

Nan Hanfei was not surprised at all when he saw Gu Yanan, but greeted him habitually, "Old rule, after we finish the on-site investigation, your disease control will take another sample, as for the specimen of the deceased, I will ask the forensic department to send you a copy, and your test results will be shared." ”

"No problem, when will your on-site inspection end?"

"Soon, before it's over, you can come with me to the back kitchen."

Restaurant kitchen.

Because of the sudden occurrence of the collective poisoning incident, a lot of work in the kitchen was temporarily stopped, and the scene was messy.

Lamb was stewed in a large pot, shredded potatoes were half fried in a small pot, and there were many bottles and jars on the stove.

Nan Hanfei pointed to the uncooked mutton in the cauldron, "The owner said that this is a new dish launched in their store today, Shiquan Tonic Soup, that is, stewed mutton, before the launch of this dish, nothing has ever happened in the store, after our on-site visit, the possibility of poisoning by others is basically ruled out, and just asked you Xicheng District Disease Control people, according to them, the hospital that received food poisoning patients said that the cause of food poisoning was likely to be aconitine poisoning." ”

Gu Yanan has noticed that several of the many condiment bottles and jars on the stove are Chinese herbal tablets, "There should be aconitum in these condiments." ”

"Do you know Chinese medicine?" Nan Hanfei asked.

"Usually my mother uses it when she makes soup, so I recognize some of it."

"Oh, no wonder the chicken soup you make is so delicious, it turns out that there is Chinese medicine in it, do you use Chinese medicine like aconitum when you make soup?"

"No, the amount of Chinese medicine such as aconitum is difficult to control, and it will be poisoned if you are not careful, my mother used it once before and was told by me, and then I never used it again."

Nan Hanfei saw Gu Yanan staring at each spice jar and observing, so he asked, "I heard that there are many types of Chinese medicine in the aconitum category, can you find out which ones are aconitum from these herbal tablets?" ”

Gu Yanan put on gloves, picked up the herbal tablets in the seasoning jar one by one, sniffed them carefully, and chose one of them, "This is the aconitum type, and it should be an artemisia on the snow from the shape and appearance." ”

"An artemisia on the snow? Such a beautiful name, but it is aconitum, it should be highly poisonous. ”

"Well, a kind of aconitum plant, traditional Chinese medicine believes that it has the effect of dispelling wind and dehumidifying, warming menstruation and relieving pain, and is often used to treat symptoms such as wind, cold and dampness, joint pain and numbness, and cold pain in the heart and abdomen, but there are strict requirements for usage and dosage, and if the dosage is too large or improperly concocted, it will cause poisoning."

Nan Hanfei sighed, "I grew up abroad, and I have heard of the breadth and profundity of traditional Chinese medicine, but I didn't expect everyone in China to know a little bit of Chinese medicine knowledge, and also apply this knowledge to daily life, but I don't know whether this practice is good or bad, after all, I have never heard of aconitum poisoning abroad, but this kind of thing seems to happen often in China." ”

"What our ancestors left behind, there are pros and cons."

Gu Yanan picked up the soup spoon and stirred the mutton soup in the pot, carefully looked at the content of the Chinese herbal slices in the soup, frowned and said, "There are a lot of aconitum slices, but according to this amount, you shouldn't be able to eat dead people, right?" ”

Nan Hanfei stared at Gu Yanan's movements, she could tell the amount of Chinese herbal medicine tablets from the naked eye alone, "Can you still tell how much poison this pot of soup contains?" With the naked eye only? How do you see that? ”

"I'm just speculating that the aconitum slices that my mother used to put when she cooked pork rib soup were similar to this, and I didn't react when I ate it, but she should have been cooking for a long time, and the cooking time in the restaurant must be short, the shorter the time, the less toxic it is, and the greater the residual toxicity."

Nan Hanfei looked at Gu Yanan, his eyes were full of admiration, "You grew up drinking poison since you were a child, are you now invincible to all poisons?" ”

"Go away, you grew up drinking poison, I only drank aconitum stewed pork ribs once, besides, how many Chinese have not eaten medicinal food?" It's just that aconitum is used to make medicinal food, and the amount of medicine is a little stronger, and something will happen when you eat it. ”

Nan Hanfei approached Gu Yanan, "Let's not eat medicinal food in the future, the chicken soup you cook is delicious, you can make chicken soup for me to drink in the future, don't make aconitum stewed pork ribs." ”

Gu Yanan glanced at Nan Hanfei, "There is angelica in the chicken soup I cooked, which is also medicinal food." ”

"It's okay to eat medicinal food, just don't put aconite, otherwise it will become a murder of your husband if you are not careful......"

Gu Yanan felt that the topic had been deviated by Nan Hanfei, so he hurriedly turned back to the topic, pointed to the restaurant owner outside, and asked Nan Hanfei, "Your people should have finished asking, I also have something to ask the boss." ”

The two of them came out of the back kitchen, Nan Hanfei said hello to the policeman who was questioning, the policeman nodded, Nan Hanfei turned back to Gu Yanan and said, "Okay, the police have finished asking, you CDC can start questioning." ”

The restaurant owner was still in a panic, and the police had to answer questions about disease control after questioning.

Before Gu Yanan could start asking, the restaurant owner began to say, "It's really none of my business, I don't want to harm people, of course I want business to prosper and everyone is safe, how can I have the motive to poison customers?" I am wronged, I am innocent......"

Gu Yanan tried his best to soften his tone, "We will investigate the truth of the matter, and now there are a few questions that you need to cooperate with to answer, and the guests at today's table have all eaten your new dishes and soup, right?" ”

"Yes, the Ten Perfect Tonic Soup is a new dish launched by the store today, a kind of mutton soup, there are a variety of medicinal materials in the medicinal diet, isn't it going to change seasons recently, it is popular to eat medicinal food, I asked for a secret recipe from the old Chinese medicine doctor, and specially made a medicinal diet of the Ten Perfect Tonic Soup, I thought it could attract customers, who knew that something would happen on the first day, why was I so unlucky......"

The restaurant owner sighed, and Gu Yanan asked: "You said that the prescription for this perfect tonic soup was obtained from the old Chinese medicine doctor?" ”
