Chapter 2996 People’s superstition about agricultural products

Farmers don’t know about E. coli infection, they don’t know what metal residues are, let alone pesticide residues. 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 E. coli infection on vegetables.

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, 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 does occur, it is difficult to detect unless it is professionally tested.

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 in these fruits and vegetables will exceed the standard.

Once people eat these things, various problems will occur, which may be life-threatening in severe cases.

The most common problem faced by rural vegetables and fruits is the problem of pesticide residues. Especially in order to sell vegetables, many farmers spray a lot of pesticides to ensure that these vegetables are not affected by pests and diseases and maintain good quality and appearance. As everyone knows, the pesticide residues in these things are very high. Even after repeated cleaning, it is difficult to remove because the plants have absorbed this part of the pesticide and have not had enough time to metabolize and evaporate, so it is difficult to remove.

Therefore, we often hear news that the Market Supervision Bureau randomly inspected agricultural and sideline products and found that the pesticide residues in the vegetables sold seriously exceeded the standard, so heavy fines appeared.

There are still many people on the Internet who don't understand, and they are trying to excuse these traders and farmers, saying that it is too heavy a step, that they are washing the blood of farmers, that they do not care about their lives, etc.

So let me ask, what would be the reaction if these people bought these vegetables with excessive pesticide residues? Food safety is more important than Mount Tai, and we must not just muddle along.

As for vegetables in supermarkets, of course there are many problems. For example, because most of these are commercial vegetables grown on a large scale, they may not be as good as some rural vegetables in terms of flavor, taste, and so-called nutrition. But it is absolutely guaranteed in terms of safety.

First of all, because it is grown on a large scale, the management is more scientific, and there will definitely be no heavy metals, E. coli, or pesticide residues.

Moreover, vegetables will undergo strict supervision measures during their growth process, including when they are harvested and sold. Only when the products are qualified will they be shipped out for sale.

At the same time, supermarkets will also conduct long-term tracking and supervision of the safety of these vegetables. Once problems are detected, they will stop accepting returns.

Finally, there is a stable after-sales acceptance channel. These farm vegetables or stall vegetables are too liquid and difficult to supervise. Even if there is a problem, it is difficult to defend your rights. Because you have no proof at all to prove that these vegetables were purchased from these people, and these people will not admit it.
