A vegetable farmer sprays pesticides in the afternoon, and someone steals vegetables at night. Who is held responsible if they get poisoned?

I recall that more than ten years ago, I followed my uncle to stake out the vegetable plot to catch a vegetable thief. The thief was caught, and we actually knew him quite well, so we let him go. Thinking about it now, it was quite awkward, but more than ten years ago such things were not uncommon. Just the other day, didn't someone chop up over ten thousand jin of watermelons? If the plot is not properly guarded, the entire vegetable plot could be carried off. Vegetable farmers not only have to guard their vegetables against being stolen, but also have to worry about being held responsible after someone steals their vegetables and eats them. It really is exhausting.
If a situation really occurs where pesticides are sprayed on vegetables in the afternoon and someone steals the vegetables at night and is poisoned to death, do not panic.
First, you must confirm the true cause directly leading to death, that is, what kind of relationship exists between eating the stolen vegetables and the death. If there is no causal relationship, then of course there is no responsibility. If there is a causal relationship, then it is necessary to analyze whether it is a direct cause or an indirect cause.
A direct cause is eating your vegetables - the vegetables had poison on them - poisoning and death. In this situation, if the pesticide application complies with national use standards, there is no responsibility. If the application amount exceeds the safe range and the purpose of application was for farming, then bearing some civil liability is enough. Of course, current pesticides are all low-toxicity pesticides, so poisoning and death would not occur, unless someone eats half a vegetable plot in one meal, in which case poisoning and death could occur. If the purpose of applying the pesticide was to prevent theft, or to take revenge on the vegetable thief, then sorry, the crime of intentional homicide will fall on your head.
An indirect cause is eating your vegetables - the vegetables had poison on them - a trace amount of toxicity triggering the onset of other fatal diseases such as cerebral hemorrhage. This situation must also be judged according to the purpose of the person applying the pesticide, whether the pesticide use complies with national standards, and other circumstances. If the person applying the pesticide aimed to control pests, and the type and amount of pesticide used were within the safe range stipulated by the state, then there is no responsibility.
The act of stealing vegetables is of course shameful, but in order to stop theft or to take revenge on the thief, deliberately increasing the dosage is absolutely not something you should do. We must use legal weapons to protect ourselves, strengthen our legal awareness, and as long as we carry out normal farming, strengthen guarding, and take legal measures when necessary, no matter what kind of situation arises, we must resolutely safeguard our own lawful rights and interests.
