Epidemiological investigation of crayfish-related rhabdomyolysis in Ma′anshan City in 2020

Abstract

Abstract
This study investigates the epidemiological characteristics of crayfish-related rhabdomyolysis cases reported in Ma’anshan City in 2020. Through case identification, patient interviews, and analysis of clinical and exposure data, the research aims to understand the incidence, demographic features, and potential risk factors associated with this condition. The findings reveal a cluster of rhabdomyolysis cases linked to the consumption of crayfish, predominantly affecting young adults. Symptoms typically manifested within hours after ingestion, with muscle pain and elevated creatine kinase levels as key clinical indicators. Possible contributing factors include improper handling, preparation methods, and individual susceptibility. The study emphasizes the need for public awareness campaigns on safe crayfish consumption and the establishment of surveillance systems to promptly detect and manage food-related toxicities in Ma’anshan.
