Key words: Vegetables, pesticides, plant protection chemicals, farmers, knowledge, practice . Background: There is a shortage of comprehensive statistics about pesticide residues in vegetables in central Vietnam, even though a number of studies on this issue have been conducted. In particular, the knowledge and practices of the producers strongly influence the quality and hygiene of products, especially when both producers and consumers have low awareness of the real situation regarding pesticide residues on vegetables. Objectives: This study had three objectives: 1. To determine the level of pesticide residues in some common vegetables in Hue city, coastal central Vietnam; 2. To describe the percentage of farmers who have a good understanding and safe practices in the use of pesticides and 3. To survey the awareness of consumers about the use of pesticides in vegetable production. Methods: This was a cross-sectional study using both quantitative and qualitative analysis. It was conducted from April to June 2013 in Hue city. Twenty vegetable farms in four wards were randomly selected to be involved in the research. In each farm, 100 samples of six vegetable types that are used daily, namely kale, lettuce, water spinach ( morning glory), coriander, herbs and laksa leaves, were collected. Then, these samples were tested for pesticide residues. In addition, structured interviews were conducted with farmers and vegetable consumers, and focus group discussions were carried out to investigate consumersâ€™ conceptions of the use of vegetable pesticides. Data were analyzed using SPSS 11.5. The study received approval from the Scientific Committee of Hue University of Medicine and Pharmacy. Results: Out of 100 collected vegetable samples, 7 did not satisfy the target residue levels for plant protection chemicals (PPCs) on vegetables (7%). Cypemethrine and phenobucarb residues were found in these samples . The vegetables that mostly had excessive pesticide residue levels were kale, lettuce and laksa leaves. There were no pesticide residues on fresh herbs and spinach. The proportion of farmers who had
good knowledge of PPC use was 67%. Regarding awareness of consumers, people mostly believed that all kinds of vegetables in the city are sprayed with PPCs. However, there were some gaps in producersâ€™ knowledge of the kinds of chemicals that should be used, the isolation time and the dosages that are safe for use. Conclusion: At this time, it appears that local vegetable producers still do not pay close enough attention to safety practices for the use of pesticides; therefore, the use of these chemicals is still a risk for community health. There should be measures to promote and encourage people in Thua Thien Hue to employ safe working practices when using pesticides, and there should be positive measures to monitor and support this process, such as communication, education and prevention recommendations from local government authorities , with monitoring from plant protection offices.
