Chapter 2786

When the skinny man saw Su Yun coming, his face immediately changed. As soon as he was about to protect the paper box with his body, he noticed a sense of suspension.

"Don't move." Fan Tianshui picked up the man with his collar without effort.

The collar strangled his neck. Before the thin man reacted, his body had shifted more than one meter, and then fan Tianshui put it down steadily.

The thin man's face is ugly. What's the origin of the man in security uniform? He's so fierce! Just when he carried himself, his arm seemed flat and didn't even bend.

"Brothers, we..." the skinny man wanted to explain, but he saw that the box had been opened and the brass plate was taken out by a simple and honest young man.

"It doesn't feel like it's just cleaned." Zheng Ren said, sliding his finger over the brass plate.

"It's impossible. How can you use this kind of thing for students." Su Yun said, "students generally use stainless steel, which is for leaders."

Hearing this sentence, the thin man burst into tears. The man looked unreasonable, but he actually understood.

"It's not about tableware. Where's the faucet?" Zheng Ren asked.

The skinny man immediately replied, "well, we use high-quality 304 stainless steel faucets..."

"Nor should it." Su Yun looked around and said, "all pure copper faucets have electroplating on the outermost layer. The function of electroplating is to prevent internal Brass Corrosion and rust. There is a lot of oil smoke in the kitchen. Coupled with the greasy and detergent on your hands when washing dishes, you often need to clean the faucet."

"Yes, yes, if you do not use the correct way to clean, it is likely to damage the electroplating layer of the faucet, causing the faucet to be corroded and rusted." The skinny man, regardless of whether anyone paid attention to himself or not, immediately said: "only those petty bourgeoisie forced decoration will use copper faucets. We all use stainless steel."

"The steel faucet does not need electroplating and is very difficult to rust. Its hardness and toughness are more than twice that of copper products, so it is very convenient to clean. I think it is used in the back kitchen, and there is no copper exposure."

Su Yun finished and went to the place where the rice was stored.

"It's OK. The rice is about to expire, but it hasn't expired yet." Su Yun said, finding the label, "it's not a fake production date."

Zheng Ren took out the brass plates in the paper case and looked at them carefully. His eyes narrowed and seemed to be thinking about something.

"The dishes are a little wilted, but they are not moldy." Su Yun said, "wait for the CDC to take samples."

"It has nothing to do with these. What vegetables absorb more copper?" Zheng Ren murmured.

"It's too much, but if it weren't for the content of vegetables growing on copper veins, it wouldn't lead to acute poisoning." Su Yun said, "boss, you overestimate the school canteen. How can you only use fresh food for each meal here? It must be a batch of goods for a week. You look at the food, it's not the first day today."

"No, we use two days!" The skinny man defended.

Su Yun didn't even look at him. He came to the freezer and opened it. He took out the meat and looked at it.

"It's quick-frozen. It's not fresh, but it's good."

"Our meat is from the Grand Manor..." the skinny man explained.

But no matter what he said, no one paid attention. Zheng Ren and Su Yun looked everywhere. Fan Tianshui suppressed the whole audience, and no one dared to move a little.

Ringer saw boss Zheng and Su Yun looking for them all the way with sterile gloves. He smiled bitterly. Why bother.

At best, it's called childlike innocence. At worst, it's called cat meddling with mice. That is to say, people would have been killed if their skills were a little less.

More than ten minutes later, people from the branch and the health bureau came one after another. Zheng Renhe and Su Yun had no harvest.

People from the CDC took samples and went back for inspection. Su Yun looked at the thin man suspiciously and asked, "I don't see any big deal. Why are you so nervous?"

The skinny man was stunned for a while, then said with a sad face, "there is no back kitchen that can't find anything wrong. If we don't say the back kitchen of the school, it's just that it's not normal for our own back kitchen to see a cockroach."

"And then?" Su Yun asked.

"Don't interrupt me, little brother. I'll tell you the truth. We don't make money from students' meals." The skinny man said, "the school has subsidies, and we mainly earn the subsidy. How difficult it is to earn some money now. I don't know how many eyes are staring at the contracted canteen. A careless direct real name report, my brother-in-law..."

As he spoke, he realized that he had slipped his tongue.

"Hehe, it's all right." Su Yun said with a smile, "don't you give your brother-in-law trouble."

"It's also right to earn less. After all, there are subsidies. I still have hundreds of hectares of land outside, which is also contracted. In general, I don't earn money for food, but mainly earn state subsidies." Said the skinny man.

"Man, you don't need money, big landlord! Why do you contract the canteen?"

"..." the thin man shut his mouth.

"The money is easy to earn. I know it if you don't say it, and the subsidy given by the school is so." Su Yun talked to himself and looked everywhere.

There are no copper utensils in the whole back kitchen. I haven't found any clues for a long time.

Su Yun was too lazy to chat with the skinny man. He looked for another lap with his boss. He saw that the CDC was sampling and preparing to go back for testing. He bumped Zheng Ren on his shoulder. "Boss, go out and have a cigarette?"

Zheng Ren frowned and nodded.

"Lin Chu, I'll leave it to you." Su Yun said casually.

Linge sighed. The two masters really couldn't provoke each other. Follow the normal process... Forget it, don't talk about the normal process, as long as they are happy.

Fan Tianshui was also very measured, and director Lin was quite satisfied.

Zheng Ren is also very confused. The students are sure of copper poisoning. The system panel of big pig hoof and the laboratory inspection of 912 have proved this.

By the time they left, the students' system panels had begun to change slightly. The reason why there is little change is that the drug injected through the gastric tube only plays a role in remission. The real treatment still needs intravenous administration of dimercaptosuccinate disodium.

Walking out slowly, Zheng Ren pondered all the way where the problem was.

It's really strange. The collective copper poisoning incident after eating in the canteen had a clear goal. Zheng Ren thought that as long as he came here, he could find out the problem and solve it directly.

Moreover, the performance of the principal of No. 2 middle school is too obvious. All this points to a big problem in the school canteen.

But... There's nothing wrong with the canteen. It can't be said to be good, but it can't be said to be bad. If this is bad, the standard will be too strict, even harsh.

What's the problem?
