Introduction:Accidents involving venomous animals, such as snakes, spiders, and scorpions, occur with some frequency, especially in rural areas. These incidents can result in serious health consequences, depending on the species involved and the speed of medical care. Objective: The goal was to analyze the trend and geographic distribution of accidents involving venomous animals in Pernambuco from 2012 to 2021. Method: This is an ecological study based on data of accidents involving venomous animals reported in the Notifiable Diseases Information System (SINAN) throughout the state of Pernambuco between 2012 and 2021, provided by the Department of Informatics of the Unified Health System (DATASUS). The Prais-Winsten model was used to analyze the trend of notifications. Spatial autocorrelation was analyzed using Moran's index to verify clusters of municipalities with a higher risk of accidents for each type of injury. Results: Of the 157,296 reported cases, scorpionism had the highest incidence rates, mainly in the Metropolitan (15.28 cases/10,000 inhabitants) and Agreste (10.39 cases/10,000 inhabitants) regions. Scorpion and bee accidents showed a growth trend in all macro-regions. The maps show higher indicators of accidents involving scorpions in the Metropolitan macro-region. Indicators of accidents involving snakes, bees, and spiders were higher in the interior of the state, specifically in the Sertão and Vale do São Francisco and Araripe macro-regions. Conclusion: Understanding the epidemiology of accidents involving venomous animals can contribute to planning actions aimed at addressing these injuries.
