Abstract:

Risk of pesticide residues in tomato production facilities in Cangnan County was studied. From 2021 to 2023, 150 tomato samples produced by agricultural entities in Cangnan County were collected for pesticide residue detection,and the Index of Food Safety (IFS) and the Food Standards Agency risk ranking system were used to assess the risk of pesticide residues. The kinds of 30 pesticide residues were detected, the overall detection rate was 99.3%, and no high toxic and excessive pesticides were detected. The top 3 pesticides with the highest detection rate were propamocarb and propamocarb hydrochloride(69.300%), procymidone (58.000%) and dimethomorph (45.300%), which were fungicides and all registered pesticides of tomato. The IFSC-MAX of pesticide residues safety index in tomato ranged 0-2.34×10-1, among which the top three were chlorothalonil (2.34×10-1), iprodione(1.59×10-1) and procymidone (1.08×10-1), all of which were registered drugs in tomato and were in a safe state. The I F S ¯ was 3.11×10-2, which was in a safe state, and the safety level was higher than the average level of agricultural products produced in Cangnan County. The risk ranking of pesticide residues detected in tomatoes is mostly at medium to low risk, and special attention should be paid to five pesticides evaluated as high-risk, including chlorfenapyr, acetamiprid, fenpropathrin, with an evaluation value of 60, indicating that pesticide residues in tomatoes in Cangnan County are in a safe state and the quality of Cangnan tomatoes are good.

Key words: tomato, pesticide residue, the index of food safety, risk ranking
