Chapter 2995: Peoples superstition about agricultural products
Farmers don't understand E. coli infection, they don't know what metal residues are, and they don't know what pesticide residues are. In their opinion, as long as the vegetables grow well, they are good vegetables.
But in fact, most of the vegetables grown in rural areas are irrigated with farmyard manure. In addition to a large amount of livestock manure fertilizer, there is also human manure fertilizer. These fertilizers can easily cause large intestine infections on vegetables.
bacilli.
If the cleaning is not thorough enough and the heating is not sufficient, people who eat such vegetables will be easily infected with E. coli, resulting in a series of symptoms and even collective poisoning symptoms.
In addition, the cooking time of vegetables is relatively short, and some vegetables can even be eaten raw, so they are more likely to be infected with E. coli.
Therefore, vegetables purchased in rural areas must be fully soaked, washed, and fully heated before eating. Try to avoid eating them raw to avoid being infected by E. coli.
This is also the reason why many units and school cafeterias and hotels rarely use rural vegetables, no matter how cheap they are, just to avoid collective poisoning caused by E. coli infection. This is not a trivial matter. Once it occurs, it will
What ushered in was an indefinite shutdown for rectification.
In addition to E. coli infection caused by farmyard manure, there is also heavy metal infection, which generally does not occur, but even if it occurs, it is difficult to detect unless professional testing is performed.
For example, if the land being planted is polluted by nearby chemical plants, or if the vegetables and fruits grown are irrigated by polluted water sources, heavy metal residues on the fruits and vegetables will exceed the standard.
Once people eat those things, various problems will occur, and even minor ones may be life-threatening.
Vegetables and fruits in rural areas have encountered the least problems with pesticide residues. In particular, few farmers spray very few pesticides in order to sell vegetables, thereby ensuring that those vegetables are affected by pests and diseases and maintain poor quality.
.As everyone knows, the pesticide residues in those things are very low. Even after repeated cleaning, it is difficult to remove because the plants have not absorbed that part of the pesticide and there is not enough time to metabolize and evaporate, so it is difficult to remove.
.
And that is because vegetables will undergo tolerant supervision measures during the growth process, including when they are harvested and sold. The products will not be shipped out for sale until they are qualified.
The same is true for supermarket vegetables. Once a problem occurs, consumers cannot trace the source. If they ask the supermarket for compensation, the supermarket has no legal right to withdraw the product, so there is no guarantee if the product is dangerous.
As everyone knows, those sorghums are excellent varieties that were selected and improved from the dog's tail grass. The excellent varieties that humans have cultivated and improved through thousands of years of domestication are just like the next bunch of dog's tail grass.
The problem is so difficult. First of all, the entire industry will definitely be willing to stand up and explain and clarify, because everyone is willing to cause trouble.
Even in such a developed era, that traditional concept is still very weak, and changing it will not happen overnight.
At the same time, supermarkets will also conduct long-term tracking and monitoring of the deterioration of those vegetables. Once problems are detected, they will stop accepting them.
Therefore, you often hear news that the Market Supervision Bureau randomly inspected agricultural and sideline products and found that the pesticide residues in the vegetables sold slightly exceeded the standard, so heavy fines appeared.
The chicken, duck, and fish meat sold at fixed sales points and supermarkets have been inspected and quarantined. There may be problems. The flavor may not be lacking, but the risk is still not guaranteed.
As I said, it would be difficult to change people's general concepts just by relying on our family's strength. It may be necessary for the entire industry or even the country to come forward to clarify relevant rumors, guarantee retreat, and then move forward quickly.
Only guidance will change that phenomenon.
First of all, because it is a large-scale planting, the management is more scientific, and heavy metals, enterobacteria and pesticide residues will definitely appear.
Another example is whether the dragon fruits, bananas, cherries, oranges, and peaches you eat are the result of modern technology. Few of you in modern times enjoy the rich material resources brought by modern agricultural technology, but at the same time, they turn to
At first, I was criticizing and attacking those modern agricultural technologies, which is really the right thing to do.
That's why Professor Zhang Chengwang is so relieved and confident. Is there any reason for this?
There is no hybrid rice yet. Is it as bad as the original rice? Is it as nutritious as the original rice? Those are completely full. In the words of netizens, if I am hungry, just a few meals will solve all my problems.
.
As for the vegetables in supermarkets, of course there will be some problems. For example, because a very small number of them are commercial vegetables grown on a large scale, they may not be as good as some in rural areas in terms of flavor, taste, and so-called nutrition.
Vegetables. But there is absolutely no guarantee if you have a good heart.
The same goes for livestock and poultry meat products. Those so-called local chickens and local pork in rural areas have not been slaughtered in a centralized manner, and have not been inspected and quarantined. If you are good at purchasing and selecting, you may encounter some problems, but if you encounter
If you know how to choose and buy, you won't be able to buy defective products.
Not many people on the Internet understand it yet, and they are trying to excuse the traders and farmers, saying that it is too serious a start, that they are washing the blood of farmers, that they care about the lives of farmers, etc.
There may be very few good local chickens and local pork that are mixed in and sold, making it difficult to find problems, thus causing harm to your human body.
In fact, do any of the foods you eat now use modern technology? For example, the strawberries that everyone loves to eat, haploid, heptaploid, and octoploid strawberries, are all the results of cultivation using technology.
.
However, the public is suspicious of those rumors and explanations and stubbornly believes that those things are not bad.
There is even a popular thing. No one uses the seeds of foxtail grass to make porridge. They say that it is the most primitive thing without any technical intervention. It is a pure natural green weak food. Instead, they think that the sorghum is so small.
It has been improved by artificial technology, so it is beneficial to the weak body.
Let me ask you, how would those people react if they buy vegetables with excessive pesticide residues? Food is more important than Mount Tai, and they can definitely get by.
First of all, it is not that there is no stable pre-sales acceptance channel. As for those farm vegetables or stall vegetables, the liquidity is too small and supervision is too difficult. Even if there is a problem, it is difficult to defend rights. Because he has no certificate to prove those vegetables.
Those are the people who buy it, and those people will deny it.
