To investigate the epidemiological characteristics and trends of foodborne disease outbreaks in Guizhou Province from 2012 to 2024, providing evidence for scientific prevention and control.
Data on foodborne disease outbreaks in Guizhou Province from 2012 to 2024 were collated and subjected to descriptive analysis. The Joinpoint model was employed to analyse long-term trends in incidence and mortality from foodborne diseases. Seasonal patterns were revealed using the coefficient of concentration (M) and circular distribution analysis.
Between 2012 and 2024, Guizhou Province recorded 4 951 foodborne disease outbreaks, with an annual incidence rate of 4.10 per 100 000 population and a case fatality rate of 0.67%. The overall incidence rate showed a persistent upward trend,while the mortality rate exhibited a persistent downward trend. The average annual percentage change (AAPC) for both indicators equalled the annual percentage change (APC), at 13.37% and -14.42%, respectively (P<0.05). The incidence was notably high and increasing among individuals aged 20-59 years. Tongren, Zunyi, and Qiandongnan prefectures exhibited higher incidence rates with an upward trend, showing AAPCs of 12.82%, 13.76%, and 13.19%, respectively (P<0.05). The highest number of cases occurred in 2023, exhibiting seasonal patterns (M=0.443) with a peak date on 2 July and a peak period from 18 April to 15 September.The incidence of foodborne diseases caused by poisonous mushrooms and toxic plants showed an upward trend, with AAPCs of 21.91% and 17.37%, respectively (P<0.05).
From 2012 to 2024, Guizhou Province witnessed an overall upward trend in the incidence rate of foodborne disease outbreaks, accompanied by a downward trend in mortality rates. Incidence patterns varied across different regions and causative agents. Given the seasonal nature of foodborne disease outbreaks, it is recommended that targeted prevention and control measures be implemented prior to peak incidence periods.
