Objective  To understand the morbidity and mortality of acute pesticide poisonings in the three cities including Changzhou, Wuxi, and Suzhou of Jiangsu Province and to provide a scientific basis for the prevention and treatment of pesticide poisoning.

Methods According to the acute pesticide poisoning reporting data of the three cities (Changzhou, Wuxi, and Suzhou) retrieved from the China Information System for Disease Control and Prevention from 2006 to 2014, the patterns of morbidity and mortality were analyzed.

Results A total of 4 790 cases of acute pesticide poisoning were reported from 2006 to 2014 in the three cities, including 316 cases of death with a fatality rate of 6.6%. There reported 714 cases (14.1%) of productive pesticide poisoning including 7 cases (0.98%) of death; the sex ratio was 1.62:1, average age was (52.55±14.35) years old, and those at 35-70 years old accounted for the largest proportion; a higher incidence rate appeared in the third quarter; organophosphorus insecticide poisoning (510 cases, 71.4%) was the dominant type of productive pesticide poisoning. There were 4 076 cases (85.9%) of nonproductive pesticide poisoning and 309 cases (7.9%) of death; the sex ratio was 0.7:1, the average age was (43.23±23.75) years old, and those at 18-58 years old accounted for the largest proportion (68.2%); there was no obvious seasonal patterns; organophosphorus in secticide poisoning accounted for 80.99% of non-productive pesticide poisoning cases.

Conclusion More non-productive pesticide poisoning cases are reported than productive pesticide poisoning cases. Related departments should enhance the safety management and the control of pesticide production and usage.
