These days, why do farmers not eat what they raise themselves, and growers not eat what they grow themselves?

Summary: Eat too much of anything and you will get sick of it. It is not that whatever you grow or raise at home means you have to eat it every day.
I have a colleague whose family raises chickens, and he hardly eats eggs, and rarely eats chicken either. When asked why, he always says that his family eats it every day, so he got sick of it. I once had a similar experience myself: when I was little, I came back from working in the fields, was very hungry, and grabbed several leftover boiled potatoes from the morning and ate them. Who knew it would ruin my stomach, with vomiting and diarrhea, and it took me several days to recover. Ever since then, I never eat potatoes again, and the sight of boiled potatoes makes me feel like throwing up. Thinking about it now, the saying "chicken farmers do not eat chicken, pig farmers do not eat pork, fish farmers do not eat fish" probably means exactly this: eat too much and you no longer value it.
But the saying "vegetable growers do not eat vegetables" is harder to understand. How can people not eat vegetables? Since you have to eat vegetables, then why not eat the ones you grow yourself? That is a bit puzzling. In recent years, pesticide residues on vegetables have always been an important indicator people care about when buying vegetables. At the vegetable market there is even this phenomenon: elderly men and women specifically pick the leafy greens that insects have nibbled on, while those that are clean and have no rotten leaves are ignored. They all believe that vegetables with insects have not been sprayed with pesticide, or have lower residues, while those clean leafy greens with no rotten leaves must have been sprayed with highly toxic pesticides, so even insects dare not eat them.
Actually, everyone is overthinking it. I remind everyone that food safety today, and the vegetable basket project, are major issues related to the national economy and people's livelihood. Several years ago the state already banned the production and sale, at the source, of highly toxic pesticides, those with high residues, and agents that are greatly harmful to human health. In addition, there are dedicated testing and supervision agencies in the market to ensure that everyone can buy green, healthy vegetables.
Coming back to this saying: you say chicken farmers do not eat chicken, but they still have to eat other meat, after all, pork, fish, and so on. Vegetable growers do not eat their own, but they still have to eat vegetables grown by others. If you only consider that you would use improper farming or growing methods to increase profits, then others are not stupid either, and they will do the same. If things keep developing this way, no one can be saved. No one will be able to eat healthy, green, good food. Then it really becomes "come on, let us hurt each other."
Now in the market, some companies use customized growing methods, such as Yimutian, Yazhuangyuan, and others, allowing consumers to participate in and track every stage of the crops or vegetables throughout the whole process, from planting, to harvest, to delivery to your hands, with full monitoring. In short, as long as supervision is strengthened, starting from the source of production, and everyone consciously obeys the law, it will surely bring everyone more and better green food.
