vegetables are an indispensable ingredient in the daily diet of residents, and their pesticide residues are directly related to the safety of the public's "vegetable basket". In order to help Jiayu Farmers Market improve the self-inspection ability of vegetable pesticide residues, recently, Wuhan Yupinyan biotechnical personnel made a special trip to Jiayu Farmers Market to carry out vegetable pesticide residue detection technology guidance activities, focusing on the operation process and precautions of organophosphorus and carbamate pesticide detection, bringing professional training to market merchants and inspectors, and building the first line of defense for vegetable safety. The technicians of Wuhan Yupinyan Bio first explained the harm of organophosphorus and carbamate pesticides based on the actual market situation - if such pesticides are excessive in vegetables, they may cause nausea, vomiting and other discomfort in the human body, and long-term intake will also damage the nervous system. It is emphasized that the detection of pesticide residues in vegetables is a key link to protect the health of consumers, so that the people present have a deep understanding of the importance of the detection work. Subsequently, the technicians focused on the company's targeted research and development of organophosphorus and carbamate pesticide testing products, and began to dismantle the detection operation process in detail. The technicians demonstrated the operation process on site, explained the key points and precautions of each step, and also conducted detailed analysis by actually testing different samples and combining the result data to help everyone master the instrument detection method and result judgment standards. In addition to the operation process, the technicians also emphasized the precautions in the testing process. In terms of the testing environment, it is necessary to keep the testing area clean and dry, avoid direct sunlight and high temperature and high humidity environment, because too high temperature will affect the activity of the reagent, and too high humidity may cause the detection card to fail due to moisture; detection tools (such as centrifuge tubes, pipettes) need to be cleaned and disinfected in advance to prevent cross-contamination. In the storage and use of the detection card, the detection card should be stored in a cool and dark place. It should be used within 1 hour after opening to avoid long-term exposure to the air. Before use, it is necessary to check whether the detection card is within the shelf life. If the packaging is damaged or discolored, it is prohibited to use it. In addition, the technicians also reminded that the test results are only used as a basis for rapid screening. If a sample suspected to exceed the standard is found, it needs to be sent to a professional testing agency for further review to ensure the rigor of the test results. Wuhan Yupinyan Bio has always taken "safeguarding food safety and serving the needs of people's livelihood" as its mission. This time, it entered the Jiayu Farmers Market to carry out technical guidance, which not only helped the market improve the self-inspection ability of vegetable pesticide residues, but also provided practical safety control methods for merchants. In the future, Wuhan Yupinyan Bio will continue to go deep into various farmers' markets, supermarkets, and planting bases, carry out more targeted technical guidance activities, and help get through the "last mile" of food safety testing through professional testing products and services, so that residents can buy safer and better quality vegetables, and protect the safety of the public's "vegetable basket".
