Abstract: This study systematically assessed cases involving the disposal of animals that died from unknown causes in public areas of Shenzhen during 2024. Utilizing resources from the Shenzhen Inspection and Testing Centre for Agricultural Product Quality and Safety and a network of 36 partner pet hospitals，an integrated emergency management system was established and implemented，comprising four key components：rapid response，professional diagnosis，safe disposal，and public education. During 2024，the project managed 43 incidents，leading to the safe disposal of 47 animal carcasses. A collaborative network of 36 designated pet hospitals was established across threeadministrative districts was established. Among the animals processed，felines constituted the majority，accounting for 57.45%（n=27/47）. The primary cause of death was identified as environmentally induced stress，with no major infectious diseases detected in t laboratory analyses. Nanshan District recorded the highest number of incidents （65.12%，n=28/43），followed by Futian District. Incidents during the high?temperature season（July?September） accounted for 46.5% of the total，a proportion significantly higher than in other seasons. The system demonstrated t effective control the average emergency response time within 30 minutes（23.4±4.2）min and significantly reduced carcass exposure time（<0.8 h），thereby mitigating zoonotic disease transmission risks. By integrating multi?agency collaboration，standardized operating procedures，and public engagement mechanisms，the project provides a replicable model for public health risk prevention and control in t megacities.
