摘　　要：目的调查分析本次一起食物中毒的原因、临床特征及检测结果,有针对性提出防控措施。方法采用流行病学方法对中毒原因进行调查,采集食物原料、调味品,患者呕吐物等进行实验室检验,并对患者的血液进行跟踪检测。结果患者主要临床表现为呕吐(82.0%)、腹泻(66.7%)、恶心(50.0%)和手足麻木(29.2%)等症状。经检测患者食用的面饼以及发面团、面粉中钡盐含量平均为34.6mg/g,患者呕吐物平均为5.05mg/g,调味料平均为6.9×10^-3mg/g。患者血液发病当日平均为2.26μg/g,经过治疗迅速降低。本次食物中毒由食用含有碳酸钡的酱香饼引起,发病24例,死亡1例,治愈23例。结论本次食物中毒为一起误食含有碳酸钡盐的面制食品引起的化学性食物中毒事件,建议规范流动食品摊点的管理,加强食物中毒现场诊断救治。Objective To investigate and analyze the causes,clinical features and test results of a food poisoning,and to put forward prevention and control measures accordingly.Methods Epidemiological methods were used to investigate the cause of poisoning.Raw food materials,condiments,patient vomit were collected for laboratory detection,and meanwhile,the patient's blood was conducted for tracking and test.Results The main clinical symptoms were vomiting(82.0%),iarrhea(66.7%), nausea(50.0%)and muscle weakness(29.2%).The average barium salt content in bread,dough and flour that patients took were 34.6mg/g,that in patients'vomit was 5.05mg/g,and that in condiment was 6.9×10^-3mg/g.The content of barium in blood was 2.26μg/g on the occurrence day,and rapidly decreased after treatment.The food poisoning was caused by bread with soy sauce containing barium carbonate.There were 24 cases in this accident,of which 1 case died and 23 cased recurred. Conclusion This food poisoning is caused by flour food containing barium carbonate salt.Thus,it is suggested to regulate management of mobile food stalls,and strengthen the diagnosis and treatment of food poisoning.
