Objective: To analyze the rule and characteristics of school food poisoning incident in Guizhou Province during 2011-2018. Methods: Data of school food poisoning incidents were collected from the Foodborne Disease Outbreak Surveillance System in Guizhou Province during 2011-2018 and statistically analyzed. Results: A total of 78 cases of food poisoning occurred in schools in Guizhou Province during 2011-2018. Among the 1 506 cases, 869 hospitalized and 1 died. May was peak time for school food poisoning. Most of the incidents (83.33%, 65/78) occurred in the school canteens. Plant origin products (50%, 39/78), especially spoiled rice, were the most common types of food poisoning in school(16.67%, 13/78). Conclusion Primary and secondary school students were the largest group for school food poisoning in Guizhou province. It was necessary to strengthen the supervision and management of school canteens and surrounding places, as well as to improve the food safety awareness of food operators and students, preventing similar incidents from happening again.

Objective: To analyze the epidemiological characteristics of plant and mushroom poisoning events among people aged 0-19 in Guizhou Province from 2015 to 2019, so as to provide the basis for prevention and control of food poisoning events among children and adolescents. Methods: Data of people aged 0 to 19 involved in plant and mushroom poisoning incidents reported by the foodborne disease outbreak surveillance system in Guizhou Province from 2015 to 2019 were collected, verified, sorted and statistically analyzed. Results: From 2015 to 2019, there were 590 cases of plant and mushroom poisoning among people aged 0 to 19 in Guizhou Province, 1 441 people were poisoned and 5 died. In May and September, family and collective dining halls were the places with the highest incidence of plant and poisonous mushroom poisoning incidents, accounting for 90.68% (535/590) of the total incidents. Poisonous mushrooms and masanberry accounted for 71.69% (423/590) of the food poisoning causes, and 5 people died of poisoning were caused by poisonous mushrooms.

Objective: To understand the epidemiological and spatial distribution characteristics of mushroom poisoning events in Zunyi, and to provide theoretical basis for the prevention of mushroom poisoning at the grassroots level. Methods: Descriptive analysis and spatial distribution of mushroom poisoning events reported by foodborne disease surveillance system in Zunyi were carried out. Results: A total of 525 cases of mushroom poisoning events were reported in Zunyi in the past ten years, with a total of 1 758 cases poisoning casesand 29 deaths. The occurrence of mushroom poisoning had seasonal fluctuation, mainly from June to October, accounting for 89.90% of the total. Family was the main place of mushroom poisoning, accounting for 96% of the total. Autochthonous gathering was the main source of mushroom poisoning events. Conclusion Mushroom poisoning is one of the main causes of food poisoning death. With the help of geographic information system(GIS), the distribution map of toadstools is preliminarily explored by combining environmental factors with the distribution of mushroom types.
