Food poisoning in South China is generally caused by vegetables such as spinach and lettuce. In the north, food poisoning is usually caused by leeks and beans.

If you accidentally eat fruits and vegetables with pesticide residues, the incubation period of poisoning is mostly within 30 minutes, ranging from 10 minutes to 2 hours for the elderly. The main symptoms are dizziness, headache, nausea, vomiting, fatigue, loss of appetite, blurred vision, numbness and weakness of limbs, etc. Severe poisoning may be accompanied by abdominal pain, diarrhea, sweating, muscle tremor, trance, speech disorder, pupil contraction and other symptoms; More serious people will have coma, spasm, incontinence, pupil contraction like a needle tip, elevated body temperature, respiratory paralysis and other symptoms.

In addition, residual pesticides will accumulate in the human body, which will lead to some diseases, such as male infertility. In addition, according to the research of the National Health Vegetable Center and other departments, the long-term accumulation and retention of pesticide residues in fruits and vegetables will also lead to chronic poisoning and induce a variety of chronic diseases, such as cardiovascular and cerebrovascular diseases, diabetes, liver diseases, cancer and so on. The accumulation of pesticides in the human body will also be passed on to the next generation through pregnancy and breastfeeding, which will endanger the health of future generations. Some fruits and vegetables bought in supermarkets can detect pesticide residues, but there are few.
