Core Viewpoint - The recent food safety supervision and sampling conducted by the Liyang Market Supervision Administration revealed that out of 765 food samples tested across 24 categories, 15 samples were found to be non-compliant with safety standards [1]. Group 1: Food Safety Monitoring Results - A total of 765 food samples were tested, covering categories such as condiments, beverages, dairy products, and more [1]. - 15 samples were identified as non-compliant, indicating a failure rate of approximately 1.96% [1]. Group 2: Non-Compliant Products Information - Specific non-compliant products included: - A soup bowl from Tianmuhu Aixiang Snack Shop, which tested positive for coliform bacteria [1]. - Multiple fruit samples from various vendors that exceeded the allowable limits for pesticide residues, such as imidacloprid and chlorpyrifos [1]. - The report includes detailed information on the non-compliant products, including the name of the product, the production date, and the specific non-compliance issues [1].
