People take food as the sky, and food is safety first. Lamb is a common meat ingredient on the public's table, and its safety and quality are directly related to consumers' health and dietary experience. In order to help meat slaughtering and processing plants improve mutton food safety testing capabilities, recently, Wuhan Yupinyan biotechnology team walked into a number of meat slaughtering and processing plants to carry out a highly targeted food safety detection technology guidance activity, hand-in-hand teaching customers to standardize the use of a variety of colloidal gold detection cards independently developed and produced by the company to escort the safety of mutton. In this technical guidance activity, Wuhan Yupinyan biological technicians first had in-depth exchanges with the heads of meat slaughtering and processing plants and testing personnel. Understand the pain points and needs faced by current processing plants in the mutton testing process, such as low testing efficiency and irregular operation that may lead to inaccurate test results. In response to these actual situations, the technicians have formulated a detailed technical guidance plan based on the characteristics of the company's products. Clenbuterol is a key indicator in meat food safety testing, and its residues can cause serious harm to human health. The clenbuterol test card produced by Wuhan Yupinyan Bio is widely recognized in the market due to its advantages of speed, accuracy and convenience. The technicians demonstrated the use process of the clenbuterol test card on the spot: starting from the sampling method of mutton samples, they explained in detail how to select representative samples to avoid affecting the test results due to improper sampling; then guided everyone to pre-process the samples, accurately control the amount of reagents added and the reaction time to ensure that the sample processing meets the detection requirements; finally, the processed samples were added dropwise to the test card, patiently explained the interpretation standards, and taught everyone how to accurately determine whether there is clenbuterol residue in mutton according to the line changes on the test card. As a banned veterinary drug, sodium pentachlorophenate residues in meat can have toxic effects on the human body. For the company's sodium pentachlorophenate test card, the technicians also conducted detailed teaching. Considering that the testing environment of the slaughter processing plant may be more complex, the technicians particularly emphasized the precautions in the testing process, such as the storage conditions of the test card, the influence of the temperature and humidity of the test environment on the test results, etc., to help the inspectors avoid possible operation errors and ensure that each test is accurate and reliable. In addition to the clenbuterol and sodium pentachlorophenate test cards, Wuhan Yupin Research Bio also focused on the promotion of colloidal gold test cards such as chloramphenicol and sulfonamide. Although chloramphenicol has been widely used in veterinary clinics, it has been banned from use in food animals because of its serious toxic and side effects; sulfonamide drug residues may also cause health problems such as allergic reactions in humans. The technicians conducted operation demonstrations for the characteristics of these two test cards. From sample extraction to test card reaction, every step is clearly explained and repeatedly demonstrated to ensure that every tester present can master the operation skills. During the teaching process, the technicians also answered the questions raised by the testers on the spot, such as the stability of different batches of test cards, the comparison and difference of test results with other test methods, etc., and eliminated everyone's concerns with professional knowledge. At the event site, the testers from various meat slaughtering and processing plants actively participated in practical exercises, and the technicians of Wuhan Yupinyan Biology were on tour to guide and correct irregular operation actions in a timely manner. Through the combination of theoretical explanation and practical operation, the testers not only mastered the use of a variety of test cards, but also deeply realized the importance of accurate detection to ensure the safety of mutton food. A person in charge of a slaughtering and processing plant said: "Before, we were always worried that improper operation would affect the results during the testing process. This time, the technical guidance of Yupinyan Bio was too timely, so that our inspectors really learned to standardize the operation. In the future, we will be more confident in the mutton testing process." Wuhan Yupinyan Bio has always adhered to the concept of "protecting food safety with science and technology", and has continuously invested in research and development to launch more efficient and accurate food safety testing products. The technical guidance in the meat slaughtering and processing plant is not only an extension service for the company's product application, but also a manifestation of the fulfillment of corporate social responsibility. In the future, Wuhan Yupinyan Bio will continue to strengthen cooperation with various food production and processing enterprises, through technical guidance, product upgrades and other methods, help the food industry to improve the level of safety testing, to create a safer and more assured food for consumers Consumption environment, so that every mutton can be safely served on the public table.
