Outline
To investigate and study the pesticide residue situation of fresh fruits and vegetables in Xining City from 2024 to 2025.
This study employed the enzyme inhibition method to conduct rapid detection and analysis of organophosphorus and carbamate pesticide residues in samples from a fresh agricultural product trading market and production sources in Xining City, involving 185 fresh vegetables and 125 fresh fruits.Specifically, 13464 batches of fresh vegetables and 5712 batches of fresh fruits, totaling 310 varieties and 19176 batches of samples were tested.
There were 30 vegetable varieties and 7 fruit varieties, and 60 batches of samples had been tested for pesticide residues exceeding the standard. Among them, the top 5 fruits and vegetables with the highest over-standard rates were cucumbers, stem lettuce, fragrant asparagus, drought-tolerant melon and eggplant. The inhibition rates of the samples with pesticide residues exceeding the standard ranged from 51.30% to 99.89%. The overall qualitative preliminary screening positive rate was 0.33%, and the pass rates were between 98.92%–99.94%. The overall sample pass rate was 99.67%, which was relatively high.
The pesticide residue situation of fresh fruits and vegetables in Xining City from 2024 to 2025 is at a relatively safe level, but there are still cases of pesticide residues exceeding the standard. It is recommended to strengthen detection continuously and monitoring to ensure food safety for citizens further.
