Objective: Understand the quality and safety of vegetables sold in Shanghai, and provide data and reference for future supervision. Methods: Public information on the supervision and sampling of vegetables by the Shanghai Market Supervision and Administration from 2019 to 2021 was collected, and the information was analyzed and summarized. Results: The statistical results of 2019—2021 show that the unqualified rate of vegetable products were 1.36%, 0.78% and 2.88%, respectively. Bulb vegetables, beans and leafy vegetables were found to be unqualified products within three years, and the unqualified rate of bulb vegetables was the highest. The main substandard vegetables were leek, cowpea, ginger, etc. and the substandard items were mainly procymidone, acetamiprid and so on. In 2019—2021, 16 kinds of drugs and heavy metal pollutants exceeding the standard were detected, of which 6 drugs were prohibited from being used in vegetable production. Conclusion: The excessive use of pesticides, the illegal use of prohibited pesticides and the failure to implement medication pre-harvest interval management are still the main problems of the quality and safety of vegetable products, especially to strengthen the supervision of high-risk vegetables such as leek, cowpea, ginger and bean sprout.
