Chapter 249 Unpredictable Toxic Food

Nitrite is a salt containing nitrite ions.

The most common nitrite is sodium nitrite.

Sodium nitrite is white to light yellow powder or granule, with slightly salty taste, easily soluble in water.

Of course, the introduction about nitrite does not stop there.

For example, ingestion of 0.3-0.5 grams of nitrite can cause poisoning, and 3 grams can cause death.

On October 2017, 10, the International Agency for Research on Cancer of the World Health Organization directly included nitrate or nitrite ingested under conditions that lead to endogenous nitrosation into the list of 27A carcinogens.

and many more.

It can be said that nitrite is definitely one of the factors with the highest incidence of food poisoning.

However, because the toxicity of nitrite is too terrifying, it was once under the most stringent supervision by the regulatory authorities.

The prepared vegetable production base is also the food production center with the highest specifications. How could there be excessive nitrite?
After thinking about it, Zhang Yue walked along the production line.

All kinds of materials are gradually turned into finished products under the assembly line operation, and finally packaged into degradable plastic lunch boxes.

Zhang Yue picked up one and looked at it carefully, frowning again.

Because of these newly made braised pork, the eye ability did not indicate.

He shook the degradable plastic lunch box in his hand towards Han Xiuru:
"This one seems to have been produced a month ago? Is there another one from the same batch?"

Han Xiuru stared: "What do you want to do?"

Zhang Yue smiled and said, "It's nothing, just take a look."

"no!"

Zhang Yue stared closely at her eyes: "Really? Don't lie to me."

Han Xiuru snorted, "So what?
I have already said that the products in the production base of prepared vegetables are not supplied to supermarkets.

Even if it is in stock, it will not be supplied. "

Zhang Yue was helpless: "Manager Han, I think you must have misunderstood me.

Although I have a good relationship with Du Ge, it does not mean that I am the same kind of person as him.

Don't you think I'm as greedy and useless as he is?
I am a very upright person and never force anyone.

High-quality pre-cooked dishes are a bonus to my supermarket, but they're fine if they don't. "

Du Zhili immediately became unhappy: "Brother Zhang, what do you mean?
What do you mean I am greedy and useless?
I think I'm a weird person. "

Zhang Yue hurriedly said: "Sorry, I'm just making a metaphor, so you can set off me.

In fact, to be honest, you are really weird! "

Du Zhijian laughed: "That's fine, that's fine, I almost thought that my character had declined recently."

Zhang Yue looked at Han Xiuru again: "Manager Han, look..."

Han Xiuru was still hesitating, but Du Zhijian said directly: "Isn't the prepared dish of braised pork next door?
Just go there directly, let's go, she doesn't want to take you there, the two of us will go there.

It's just a broken warehouse, nothing rare.

If it weren't for your brother Zhang, I would think it tasted too strong if I went there. "

After speaking, lead the way ahead, and Zhang Yue follows behind.

The door opened, and a gust of cold air rushed in.

To be precise, this is a cold storage, but the temperature is adjusted higher.

Zhang Yue roughly scanned the internal structure and found that the cold storage was larger than the two warehouses of Shiyue Food Factory combined.

It was densely packed with sealed cartons.

There are a few workers pushing small carts, coming in and out non-stop.

Zhang Yue looked along the rows of stacked cardboard boxes, and didn't find any problems at first.

But when he came to a corner, the red words on the eye encyclopedia appeared again.

The nitrite is still seriously exceeded.

He pointed his finger: "When was this batch produced?"

Du Zhijian walked over with a smile: "You don't need to ask, just look at the date and you'll know."

After finishing speaking, he walked over: "June 25th, from now... Let me do the math!

One month and two days have passed. "

Zhang Yue picked up the braised pork lunch box in his hand and found that the date on it was June 25th.

Turning his head to look at Han Xiuru, who also came over, Zhang Yue's expression was unusually dignified: "Are all the finished products produced this day here?"

Han Xiuru nodded: "It's all here, okay, I won't hide it from you.

The products of the prefabricated vegetable production base are not as popular as imagined for the time being because they are more expensive.

But this is just the beginning, and I am confident that all the inventory will be cleared out in half a year at most. "

But Zhang Yue breathed a sigh of relief: "Fortunately, these braised pork are unsalable."

Han Xiuru stared: "Hey, what do you mean?"

Zhang Yue looked at her: "The braised pork you produced on June 25 has seriously exceeded the standard of nitrite.

If people take it rashly, there is a high probability that it will cause food poisoning. "

Han Xiuru's face immediately changed: "Nonsense!
How could nitrite exceed the standard?

Every box of prepared vegetables produced by the prepared vegetables production base has passed at least three quality inspections.

And these three inspections belong to different departments. Even if one of the departments makes a mistake due to work negligence, the other two departments can also check it out.

Even in order to improve the enthusiasm of quality inspectors, I have also formulated a high bonus system.

In other words, as long as they can detect a problem with a box, they can immediately get a bonus of 1000 yuan.

If you don't believe me, go and see for yourself. "

But Zhang Yue shook his head: "I don't care how you do the quality inspection?

But it is a fact that nitrite exceeds the standard. "

"You are talking nonsense!"

Zhang Yue still wanted to talk, so Du Zhijian said, "I told you two to stop arguing.

Is the nitrite in this batch of braised pork exceeding the standard? Just test it directly? "

After speaking, he found a ladder and climbed to the top of the warehouse, and took down two boxes of what Zhang Yue said was problematic.

At this time, a middle-aged man came with a young woman.

"Manager Han, which batch of braised pork has exceeded the limit of nitrite?

How can you be so careless?Do you know how harmful nitrite is to the human body? "

Han Xiuru said: "I didn't say this, he said it."

After speaking, he pointed to Zhang Yue, first introduced his identity, and then said to Zhang Yue:

"This is Wang Bingchao, the person in charge of the gourmet laboratory of the prepared dish production base."

Wang Bingchao looked at Zhang Yue, without the doubt and anger he imagined, but smiled and said:

"It turned out to be Manager Zhang, who has known his name for a long time.

Originally, I thought that I would pay a special visit to you when you came to the base.

In the end, I waited hard for two months, but I didn't expect to see your shadow. It's really a pity. "

Zhang Yue was taken aback: "You know me?"

"Of course I know, my father-in-law fainted from a sudden cerebral hemorrhage a few years ago, and he recovered only after taking your medicine.

Some time ago you were doing a live broadcast in northern Shaanxi, and I bought [-] boxes of apples. "

Zhang Yue nodded.

No wonder!
Wang Bingchao turned to the girl behind him and said, "Take a sample and test it.

Be careful to test several times, and you must not make mistakes. "

The girl nodded and started working.

After 10 minutes, she said to everyone: "No problem was found in the test, and the nitrite content in this box is all up to the standard."

As soon as the words came out, everyone looked at Zhang Yue.

Wang Bingchao asked: "Manager Zhang, did you make a mistake?

Although Manager Han has a bad temper, she has nothing to say at work, and basically there will be no problems. "

But not as polite as Wang Bingchao, she looked at Zhang Yue with a dull expression: "I think you should give me an explanation.

Otherwise I will hold you accountable. "

Zhang Yue also frowned, and he asked the girl doing the experiment: "Are you sure this box of braised pork is okay?"

"It's definitely not a problem. I used spectrophotometry and diazo coupling to test separately.

And ten sets of experiments were done for each type, and no abnormalities were found. "

Zhang Yue frowned, as if he couldn't figure something out.

Wang Bingchao suddenly asked: "Could it be the cause of endogenous nitrosation?"

Du Zhijian asked: "Endogenous nitrosation, what is it?"

"A relatively special phenomenon of nitrite poisoning, in layman's terms, is that the toxicity of nitrite cannot be detected in the food itself.

But after eating, the food will react with certain bacteria in the digestive tract to generate nitrite. "

Du Zhijian was stunned: "No way, there is such an operation, why have I never heard of it before?"

Wang Bingchao said: "This kind of situation is actually relatively rare.

Let me give you an example. People often say that you can't drink overnight water, and many people have questioned it.

In fact, there is a scientific basis for not drinking overnight water.

Boiling water will inactivate all bacteria in it.

But if the storage time is too long, the bacteria will be polluted again and decompose the nitrogen-containing organic matter inside into nitrite.

Although the content of this nitrite is relatively small, it is easy to generate nitrosamines in the stomach.

Nitrosamines are primary carcinogens. "

After Du Zhijian finished speaking, he hurriedly said, "Stop!

I said, Lao Wang, did you do it on purpose?

Knowing that I like to drink overnight water the most, you still say that?
Let me tell you, stop talking nonsense, get down to business quickly, and if you talk nonsense, believe it or not, I will beat you? "

Wang Bingchao glanced at the girl, who nodded, and grabbed ten mice.

Wang Bingchao said with a smile: "It's very simple to detect whether there is a problem, just use a living body."

After speaking, he picked up a piece of braised pork and fed it to a small white mouse.

The little white mouse ran over happily after smelling the aroma, and ate up the meat in a few mouthfuls.

Then it began to circle happily in the cage.

5 minute later.

Han Xiuru looked at the still lively little white mouse: "Isn't it all right? There is absolutely no possibility of problems with the food I make."

However, as soon as she finished speaking, the little white mouse suddenly let out a loud chirp, and then began to roll over non-stop.

In less than a minute, he lay motionless on the ground.

Wang Bingchao frowned, lifted the mouse's tail and shook it a few times: "It's dead!"

"Impossible! How is it possible?"

Han Xiuru's face changed drastically, and she suddenly unpacked the other braised pork boxes in the box and fed them to other mice.

These little white mice also ate up the meat just like the little white mouse just now.

Everyone watched the situation of these little white mice intently.

Time passed by one minute and one second, and suddenly, a little white mouse yelled and began to struggle on the ground.

Immediately afterwards, the other mice also kept rolling.

In less than 1 minute, all ten mice died.

Everyone at the scene turned pale.

Especially looking at the corpses of these ten little white mice.

Han Xiuru's cold sweat trickled down even more.

If these braised pork were eaten by others, the consequences would be unimaginable.

Not to mention that it supplies schools and troops.
