The transmission of salmonellosis in China necessitates big data analytics of <i>Salmonella</i> outbreaks (SO) to inform policymaking and interventions. This study identifies epidemiological patterns and prevention priorities for SO in China and provides several estimated indicators suitable for predictive modeling and machine learning to quantify epidemic trends, which can help prevent and control the spread of salmonellosis in China.
