"Brother, you mean to say that they drank fake wine containing methanol?" Gu Yanan exclaimed.

"It may also be that I drank the industrial alcohol containing methanol that the restaurant uses as fuel, which has not happened before."

Gu Yanan remembers a case of methanol poisoning that he had dealt with, because several people were drinking in a restaurant, and they brought their own wine, and the barrel used to hold the wine was the same as the industrial alcohol barrel used in the restaurant to support combustion.

The diner mistook the barrel used by the restaurant to hold industrial alcohol for the wine he had brought in, and after drinking it, he developed methanol poisoning.

A total of eight people drank in that accident, two died, three were blind for life, and three drank relatively little, leaving sequelae of varying degrees.

Gu Yanan: "Okay, I know, I'm going to Daliang Town, where the wedding banquet was held, and Xushan Village, which has the largest number of deaths, to conduct an on-site mobile disease investigation, and the source of methanol will soon be figured out." ”

The suburbs of Lianhai City, Daliang Town, Shanhai Farmhouse.

Gu Yanan, Lu Li, Wang Xiaoxiao and Zhou Jie drove the on-site flow shunting of the CDC, and after more than an hour's drive, they arrived at the gate of Shanhai Farmhouse.

According to the information provided by the hospitalized personnel, the wedding banquet they attended that day was in the Shanhai farmhouse.

Gu Yanan showed his work card, and the owner of Shanhai Farmhouse was willing to cooperate with the investigation, and took the initiative to take Gu Yanan and his party to the back kitchen of the farmhouse.

Gu Yanan asked Lu Li and Wang Xiaoxiao to simply collect some food samples and go back.

Gu Yanan also focused on checking the wine supply of Shanhai Farmhouse, especially the type of wine served on the day of the wedding banquet.

The owner of Shanhai Farmhouse took Gu Yanan to the warehouse where the liquor was stored in the hotel, pointed to several of them, and said, "This is the wine they designated for the wedding banquet that day, a kind of white wine, a kind of red wine, and several kinds of drinks." ”

Gu Yanan sampled the wine used for the wedding banquet.

With the collected samples, I returned to the CDC's laboratory from Shanhai Farmhouse.

Measuring the amount of methanol in wine is a simple chemical experiment.

The results came out quickly, and Gu Yanan did not detect excessive methanol in the wine he brought back from Shanhai Farmhouse.

Looking at the test results, Gu Yanan wondered in his heart: Isn't it a problem with wine? Could it be that they drank industrial alcohol, the accelerant used to heat the hot pot in the restaurant?

No problems were found in this on-site survey, and the second on-site survey was carried out immediately.

This time, Gu Yanan drove his own car and went to Shanhai Farmhouse alone.

Finding the owner of Shanhai Farmhouse, Gu Yanan asked: "Does your restaurant use industrial alcohol as an accelerant for heating dishes?" ”

As soon as Gu Yanan's question came out, the owner of the farmhouse understood what Gu Yanan meant, and the boss hurriedly explained: "Our restaurant uses industrial alcohol as an accelerant for hot dishes, but we usually keep industrial alcohol very well, and we will definitely not let guests take it by mistake, let alone use industrial alcohol to mix fake wine to fool guests." ”

"Where do you usually put the industrial alcohol you use as an accelerant? I'd like to take a look. ”

The owner of the farmhouse took Gu Yanan to the back kitchen of the restaurant, where there was a separate warehouse next to the back kitchen, and in the warehouse there were several small plastic buckets with inconspicuous labels - industrial alcohol, toxic, flammable.

The boss pointed to the plastic kegs containing industrial alcohol and explained to Gu Yanan, "The industrial alcohol in our hotel is usually placed here, and it is guarded by a special person, so it will not be taken by the guests by mistake." ”

There was no problem found in the farmhouse where the wedding banquet was held, and Gu Yanan decided to visit the victim's home.

Suburbs of Lianhai City, Daliang Town, Xushan Village.

Gu Yanan first went to the bride and groom's house where the wedding was held at Shanhai Farmhouse that day.

The groom's father died after being taken to the town hospital on the night of the wedding.

The wedding was followed by my father's funeral.

The groom's name is Xu Dahai, the bride's name is Han Xiaohua, and when Gu Yanan found Xu Dahai, he was at his parents' house next door, handling his old father's funeral.

Gu Yanan showed his work card, explained his intention, and wanted to investigate the cause of the groom's father's death.

Xu Dahai took Gu Yanan to a secluded place in the backyard, temporarily cutting off from the noise of the funeral in the front yard.

Xu Dahai's face was sad, "My dad just drank and died, what else is there to investigate?" ”

Gu Yanan explained: "You also know that many people in Xushan Village who attended the wedding banquet were sent to the hospital, and after the hospital examination, it was determined that it was methanol poisoning, so we suspect that your father also died of methanol poisoning. ”

"Methanol poisoning? What do you mean? ”

"We suspect there was something wrong with the wine at your wedding reception that day."

Xu Dahai was stunned for a moment, and then shook his head, "Impossible, I also drank that day, why am I fine?" ”

"There is more than one type of wine in the wedding banquet, although we went to Shanhai Farmhouse to investigate, and no methanol exceeded the standard in the white wine and red wine used for the wedding banquet that day, but we suspect that your father and others drank other wine."

Xu Dahai remembered the scene of the wedding banquet that day, because he and the bride had been busy toasting the guests and had not paid much attention to his father, as for what kind of wine his father drank and how much he drank, he did not know.

Xu Dahai's wife, Han Xiaohua, saw Xu Dahai and a beautiful woman in the backyard, and also followed, hearing the conversation between the two, Han Xiaohua said: "On the day of the wedding banquet, my mother-in-law has been with my father-in-law, if you want to know the situation of your father-in-law, you have to ask my mother-in-law." ”

Xu Dahai waved his hand at his wife Han Xiaohua and said, "Call my mother over." ”

Han Xiaohua trotted out of the backyard.

Soon, an elderly woman walked in.

Xu Dahai stepped forward to meet the old woman and helped the old lady to sit on a wooden bench under the grape trellis in the backyard.

Xu Dahai introduced the old woman and said: "Mom, this is an expert from the Municipal Center for Disease Control and Prevention, investigating the cause of my father's death, and I want to ask you something, and you can say whatever you know." ”

"Hmm." Although the old lady looked sad and there were tears in the corners of her eyes that she had just cried, she still agreed happily in the face of her son's instructions.

Gu Yanan began to ask: "Auntie, I want to ask, what kind of wine did your husband drink on the day of the wedding banquet?" ”

The old woman thought for two seconds before she began to speak: "At the beginning, I drank the white wine prepared for the wedding banquet, and drank two glasses of red wine, and then the wine at our table was drunk, and the old man went to the front desk of the hotel to bring a large bottle of white wine. ”

Gu Yanan knew that the drinks prepared by Shanhai Farmhouse Hotel for Xu Dahai's wedding banquet included a kind of white wine and a kind of red wine, but he didn't know what a large bottle of white wine that the groom's father brought back from the front desk of the hotel was.

Gu Yanan asked: "Auntie, do you remember what brand of liquor your husband brought back from the front desk of the hotel after drinking the wine on the wedding banquet table?" ”

The old woman shook her head, "I didn't look closely, I don't remember." ”
