Core Viewpoint - The article highlights the rigorous food safety measures implemented at the Xinjiang Jiuding Agricultural Products Wholesale Center, emphasizing the importance of sampling and testing to ensure the quality and safety of agricultural products, especially during the peak trading season before the Spring Festival [1][2][3]. Group 1: Sampling and Testing Process - The sampling process involves trained personnel conducting tests on incoming vehicles, ensuring that each vehicle presents a "Compliance Certificate" before entry [1][2]. - Sampling is performed using a systematic approach, where samples are taken from different batches and locations within each vehicle to ensure representativeness and eliminate safety risks [2][3]. - The testing laboratory operates under strict standardized protocols, with personnel engaged in various stages of testing, including registration, extraction, and analysis [2]. Group 2: Safety Measures and Compliance - The testing regime consists of mandatory inspections for all vehicles ("vehicle-to-vehicle mandatory testing") and targeted risk assessments for high-risk products, maintaining a compliance rate of over 99% [3]. - The "one product, one code" system is employed for efficient testing, with results available within half an hour, and data is uploaded to the Jiuding traceability platform for merchants to access compliance certificates [3]. - In case of non-compliance, immediate actions are taken, including issuing a market withdrawal notice and potential destruction of unsafe products to prevent them from reaching consumers [3]. Group 3: Impact on Market and Consumer Confidence - The rigorous testing and traceability measures enhance consumer confidence, allowing merchants to sell products with assurance and consumers to purchase with peace of mind [2][3]. - The comprehensive safety protocols contribute to a secure food supply chain, reinforcing the quality of agricultural products and enhancing the overall consumer experience during the festive season [3].

Core Viewpoint - Agricultural product quality safety is the first line of defense for food safety, with agricultural product inspection laboratories being the core battleground to safeguard this line [2][3]. Group 1: Importance of Inspection Laboratories - Agricultural product inspection laboratories are essential for accurately controlling key indicators such as composition, harmful substance residues, and physicochemical properties [2][3]. Group 2: Common Instruments and Their Uses - pH Meter: Measures pH value [4] - Conductivity Meter: Measures the conductivity of electrolyte solutions [4] - Liquid Chromatograph: Qualitative and quantitative analysis [4] - Gas Chromatograph: Qualitative and quantitative analysis [4] - Automatic Potentiometric Titrator: Acid-base, redox, precipitation, and complex titrations [4] - UV-Visible Spectrophotometer: Measures the absorption of substances at different wavelengths for quantitative analysis [4] - Atomic Absorption Spectrophotometer: Quantitative analysis based on the absorption of characteristic radiation by ground state atoms [4] - Karl Fischer Moisture Meter: Measures moisture content [4] - Fourier Transform Infrared Spectrometer: Qualitative and quantitative analysis [4] - Colorimeter: Measures the color of agricultural products [4] Group 3: Additional Instruments - Ion Chromatograph: Qualitative analysis [5] - Fluorescence Spectrophotometer: Measurement of elements that easily form hydrides or gaseous components [5] - Refractometer: Measures refractive index [5] - Kjeldahl Nitrogen Analyzer: Measures nitrogen content in proteins [5] - Mycotoxin Testing Instruments: Measures aflatoxin content [6] - Sulfur Dioxide Testing Instruments: Measures sulfur dioxide concentration [6] - Fiber Analyzer: Measures fiber content [6] - Fat Analyzer: Measures fat content [6] Group 4: Comprehensive Detection System - The instruments cover basic physicochemical indicators (e.g., pH, moisture, sugar content), critical safety indicators (e.g., pesticide residues, aflatoxins, heavy metals), and nutritional components (e.g., amino acids, fats, fibers), creating a comprehensive detection system [6].

Core Viewpoint - The competition aims to enhance the skills of agricultural product quality safety testing personnel in Shandong Province, contributing to the overall agricultural quality and safety standards in the region [1] Group 1: Competition Overview - The 2025 Shandong Province Agricultural Product Quality Safety Testing Skills Competition is part of the provincial selection for the National Agricultural Industry Vocational Skills Competition [1] - The event is organized by the Shandong Provincial Department of Agriculture and Rural Affairs, the Provincial Federation of Trade Unions, and the Provincial Animal Husbandry Bureau, with the Shandong Academy of Agricultural Sciences as the host [1] Group 2: Objectives and Impact - The competition serves as a comprehensive review of the agricultural product quality safety testing system in the province, promoting learning, practice, and application through competitive events [1] - It aims to motivate testing personnel to enhance their skills and knowledge, thereby ensuring food safety for the public and strengthening the agricultural product quality safety defense [1] Group 3: Current Infrastructure - Shandong Province currently has over 160 agricultural product quality testing institutions certified through metrology certification and institutional assessment [1] - The testing team structure includes provincial and municipal testing centers as the main bodies, supplemented by third-party testing institutions, providing robust technical support for agricultural product quality safety [1]

Core Viewpoint - The Guangdong Academy of Agricultural Sciences has led the drafting of two national standards for feed testing, which will be implemented on February 1, 2026, enhancing the standardization system of the feed industry in China [2][5][11]. Group 1: New Standards - The two new national standards are GB/T 21108-2025 for the determination of chloramphenicol, thiamphenicol, and florfenicol in feed using high-performance liquid chromatography-tandem mass spectrometry, and GB/T 22262-2025 for the determination of chlorohydroxy pyridine in feed [3][4][8][9]. - These standards will provide technical support for regulatory authorities to ensure that feed products meet health and safety requirements, promoting industry development and enhancing market competitiveness [11][12]. Group 2: Research and Development - The Quality Standards and Monitoring Technology Research Institute has been dedicated to agricultural product quality safety, standardization research, and evaluation technology, having completed the drafting and revision of over 190 national, industry, and local standards [13][14]. - The institute plans to continue its research on standardization of detection technologies for agricultural products and inputs, providing technical and standardized support for high-quality agricultural development [16].
