“活鱼被人为麻醉”，重庆通报！

Core Viewpoint - The article highlights the illegal use of tranquilizers in the fish trade in Chongqing, specifically focusing on substances like "鱼护宝" and "鱼安宝," which contain the active ingredient eugenol, raising health concerns for consumers [2][9]. Group 1: Regulatory Actions - The Chongqing Market Supervision Administration conducted a comprehensive enforcement operation on March 17, leading to the discovery of tranquilizers used by fish vendors [2]. - A total of 453 fish trading markets and 2,534 fish vendors were inspected, resulting in 44 violations, including three cases of tranquilizer use [2]. Group 2: Health Risks - Eugenol, the main component of the tranquilizers, is classified as a "three-no" product (no production date, no manufacturer, no production license) and poses potential health risks, particularly with long-term use [9]. - Medical experts warn that prolonged exposure to eugenol can damage liver and kidney functions, and special populations such as pregnant women and children should avoid it [9]. Group 3: Market Practices - Investigations revealed that fish transported over long distances often appear in a "sleeping" state due to human intervention rather than natural behavior, with vendors using tranquilizers to facilitate handling and prevent fish scales from falling off [5][7]. - The use of eugenol-based products has emerged as a replacement for previously banned substances like malachite green, which was prohibited in 2002 [9].
