"I'm sure!" Tian Chunhua nodded: "Our kindergarten is very strict with children, and children are never allowed to eat snacks indiscriminately, if you don't believe it, you can ask those children and ask them if they eat snacks in the kindergarten." ”

"Tian Yuanchang, before the matter is investigated, your kindergarten will be temporarily closed, I hope you can cooperate." Ma Xiaoyao handed Tian Chunhua a notice of suspension of business for rectification.

"Huh?" Tian Chunhua's face changed: "How long will you be suspended?" ”

"At least after the investigation is clear, okay, I'm going to go back and test the food, and I'll take my leave." After speaking, Ma Xiaoyao led Kong Liang and others out of the kindergarten, and before leaving, Ma Xiaoyao also took away all the meals that the students had eaten at noon.

Back at the Health Bureau, Ma Xiaoyao immediately sent the food to the laboratory department for examination.

An hour later, the test results came back.

All meals were basically qualified, except for the ham meat, which was found to contain mercury after testing by the staff of the Health Bureau.

Ma Xiaoyao carefully looked at the test report and asked the staff of the laboratory department, "Are you sure that the ham meat contains mercury?" ”

The staff nodded: "We have repeatedly tested three times, ham meat does contain a small amount of mercury, the scientific name is liquid mercury, liquid mercury is not easy to be absorbed by the human stomach, so a small amount of food is not too harmful to the body, but if it is cooked, volatilized by heat and inhaled into the body, it may cause mercury poisoning in Yanzhòng, and the ham meat taken back from the kindergarten has obviously been heated and steamed, so those students will be poisoned after eating, but fortunately, it was found in time. Otherwise, those children will be in danger. ”

Ma Xiaoyao frowned: "How can mercury appear in the ham meat?" ”

"I don't know about this, but I guess it may be caused by the negligence of the manufacturer." The staff guessed.

Ma Xiaoyao pondered for a moment, then turned his head to look at Kong Liang: "Kong Liang, you go to the hospital now to find out the cause of those children's poisoning, and see if they are mercury poisoning." ”

Kong nodded brightly, turned around and strode away.

Ma Xiaoyao put away the test report, said hello to the staff of the laboratory department, and then led the two subordinates back to the kindergarten.

Seeing the horse go and return, the head of the garden, Tian Chunhua, was stunned for a moment.

"Chief Tian Yuan, where did you buy your school's ham meat?" Ma Xiaoyao didn't say anything and asked bluntly.

"Ham meat?" Tian Chunhua was stunned: "This ...... If you ask the chef, usually all the dishes and meats are bought by them. ”

"Then please call the cook." Ma Xiaoyao said.

"The chef has gone home." Tian Chunhua said: "The kindergarten was closed, so I let the cooks and teachers go home. ”

Ma Xiaoyao frowned: "Can you contact those chefs now?" Give them a trip back! ”

Tian Chunhua glanced at Ma Xiaoyao and asked suspiciously, "Is there something wrong with that ham meat?" ”

"We found mercury in the ham meat." Ma Xiaoyao didn't hide it, and directly told the test results.

"Huh?" Tian Chunhua's face changed: "Mercury? How is this possible! ”

"I'm also surprised, but it's true, we did find mercury in the ham meat, and if my guess is correct, those children just took the ham meat, and the mercury was acutely poisoned." Ma Xiaoyao said expressionlessly.

"This ......" Tian Chunhua's expression was a little panicked: "Comrade, we really didn't mean it, and we didn't know that ham meat contained mercury......"

Ma Xiaoyao waved his hand: "Call the chef who bought the ham meat over and ask to know what's going on." ”

"Yes, yes, I'll call the chefs right now." Tian Chunhua came to her senses and hurriedly took out her mobile phone and started calling.

At this moment, Kong Liang hurried to the kindergarten: "Deputy Section Chief Ma, I asked clearly, those children do contain a small amount of mercury in their bodies, the doctor said, fortunately, the children take less mercury, after cleaning the stomach and disinfection, now the children are out of danger." ”

"It's really mercury poisoning." Ma Xiaoyao nodded slightly.

"The chefs are coming right here." Tian Chunhua hung up the phone and said to Ma Yao.

After more than ten minutes, two women came to the kindergarten in a hurry.

Tian Chunhua immediately said: "The two of them are the chefs of the kindergarten, and the children's diet is usually managed by the two of them, the tall one is called Zhang Yuxiang, and the short one is called Song Yufen, both of whom are professional chefs." ”

"You bought the ham?" Ma Xiaoyao glanced at Zhang Yuxiang and Song Yufen, the two women were about the same age, both were around forty years old, and their appearance was very ordinary, neither beautiful nor ugly.

Zhang Yuxiang nodded: "I bought all the ham meat." ”

"Where did you buy it?" Ma Xiaoyao asked.

"In the Huimin supermarket next to the kindergarten, I usually buy Yurun ham, but today Yurun ham is sold out, and in the end, I have no choice, so I bought some other brands of ham meat." Zhang Yuxiang replied.

"Let's go, now you take us to Huimin Supermarket to have a look." Ma Yao commanded.

"No problem." Zhang Yuxiang nodded, turned around and led Ma Xiaoyao and the others out of the kindergarten, and even Tian Chunhua followed.

A few minutes later, Zhang Yuxiang stopped at the door of a supermarket: "This is the supermarket." ”

Ma Xiaoyao looked up and found that the scale of this supermarket is not small, through the glass door, you can clearly see that the supermarket is full of shelves, and there are piles of various things on the shelves, and there is a sign hanging on the glass door, which reads "Huimin Supermarket".

"Let's go, let's go in." Ma Xiaoyao pushed open the glass door and walked into the supermarket.

Zhang Yuxiang, Kong Liang and others hurriedly followed.

A salesman came over and greeted Ma Xiaoyao and the others politely: "I don't know what you want to buy?" ”

Ma Xiaoyao took out his documents: "I am from the Food Safety Section of the Health Bureau, please call your boss over." ”

The salesman was stunned: "Ah, please wait." With that, the salesman turned around and walked away quickly.

After a while, a man in his thirties walked out of the room, followed by the salesman who had just left.

"I am the owner of this supermarket, my name is Liu Zitong, I don't know how many people come to my supermarket ......," the man introduced himself.

Ma Xiaoyao handed his ID to Liu Zitong: "I am from the Food Safety Department of the Health Bureau, and I came to you to investigate something." ”

Liu Zitong glanced at the documents, and his expression suddenly became respectful: "It turned out to be Deputy Section Chief Ma, welcome, welcome." As he spoke, Liu Zitong returned the certificate to Ma Xiaoyao, the Food Safety Department of the Health Bureau is the department in charge of the supermarket, of course Liu Zitong should be polite.

Ma Xiaoyao put away his documents and said, "Boss Liu, you should know that there is an art kindergarten nearby, right?" ”

Liu Zitong nodded: "I know, what's wrong?" ”

"At noon today, many students in the kindergarten had symptoms such as diarrhea, vomiting, and dizziness, and were sent to the hospital to be diagnosed with food poisoning." Ma Xiaoyao said: "After our health bureau conducted a laboratory test on the food in the kindergarten, we finally found the root cause of the food poisoning. ”

Liu Zitong raised his eyebrows: "What is it?" ”

"Ham meat." Ma Xiaoyao took out a test report from his bag and handed it to Liu Zitong: "After testing, it was found that the ham meat contained a small amount of liquid mercury, which is commonly known as mercury, which is commonly known as mercury, which will form highly toxic after heating. Speaking of this, Ma Xiaoyao paused for a moment, and then continued: "And this ham meat containing mercury is purchased from your supermarket. ”

"Impossible!" Liu Zitong was anxious when he heard this: "How can the ham meat sold in our supermarket contain mercury, this is absolutely impossible!" No wonder Liu Zitong is in a hurry, if the news that ham meat contains mercury spreads, it is estimated that no one will dare to buy anything in his supermarket anymore.

"Boss Liu, whether you believe it or not, but that's the case." Ma Xiaoyao stretched out his hand and pointed at Zhang Yuxiang: "I don't know if Boss Liu recognizes her?" ”

Liu Zitong glanced at Zhang Yuxiang and nodded: "I know, she often comes to my supermarket to buy things, and she seems to be the chef of the art kindergarten." ”

"Zhang Yuxiang, tell Boss Liu what happened." Ma Xiaoyao nodded to Zhang Yuxiang.

"I bought the ham meat with mercury from this supermarket, and by the way, I have a supermarket purchase invoice here." Zhang Yuxiang took out a shopping invoice from her pocket and handed it to Liu Zitong.

Liu Zitong hesitantly took the shopping invoice, glanced at it, and his face suddenly became ugly, there were indeed ten ham meat on the shopping invoice.

"Boss Liu, please take us to the place where ham meat is sold to have a look." Ma Xiaoyao's tone was quite kind.

Liu Zitong didn't refute this time, just nodded, and led Ma Xiaoyao and the others to the area where ham meat was sold.

From east to west, several shelves are filled with ham, and a rough count shows that there are dozens of brands.

"Zhang Yuxiang, what brand of ham meat are you buying?" Ma Xiaoyao asked.

Zhang Yuxiang pointed to a shelf opposite: "It's this kind of ham in the wind season." ”

Ma Xiaoyao picked up a wind season ham and looked at it, and found that the ham packaging was not marked with a production address, not even a sales call, and there were only four big words on the huge packaging bag, "wind season ham", and there were some methods and precautions for using ham.
