摘要
目的 掌握辽宁省食源性沙门氏菌感染的流行变化趋势,为食源性疾病防治提供科学依据.方法 采集2014-2022年辽宁省哨点医院食源性疾病主动监测病例信息和患者粪便标本,按照《国家食源性疾病监测工作手册》规范程序分离培养沙门氏菌,采用描述流行病学方法对沙门氏菌感染病例的特征进行统计分析.采用x2检验对不同性别、年龄、职业及可疑暴露食品等沙门氏菌检出率进行比较,组间存在差异用Bonferroni进行两两比较,P＜0.05差异有统计学意义.结果 共收集到28 009例食源性疾病病例,检出沙门氏菌241例,检出率为0.86％.第二、第三季度沙门氏菌检出率较高,分别为1.41％及0.89％.0～3岁年龄组沙门氏菌检出率最高(1.90％).职业分布中散居儿童检出率最高为2.20％.可疑暴露食品中沙门氏菌检出率最高的为婴幼儿食品(3.77％),其次为蛋与蛋制品(2.13％).结论 沙门氏菌感染的流行高峰集中在每年的6-9月,呈明显夏秋季高峰.高峰时期要重点关注婴幼儿沙门氏菌的感染.
Abstract
Objective To understand the epidemic changing trend of foodborne Salmonella infections in Liaoning Province,and to provide a scientific basis for prevention and control of foodborne diseases.Methods The information and stool specimens of active surveillance cases of foodborne diseases were collected from sentinel hospitals in Liaoning Province from 2014 to 2022,Salmonella bacteria were isolated and cultured according to the standard procedure in the National Manual of Foodborne Disease Surveillance.Descriptive epidemiological methods were used to statistically analyze the characteristics of cases of Salmonella infections.Chi-square test was employed to compare the detection rates of Salmonella in different genders,ages,occupations and suspected exposed food.The differences between groups were compared pairwise using Bonferroni correction.P＜0.05 was considered statistically significant.Results A total of 28,009 cases of foodborne diseases were collected,and 241 cases of Salmonella infections were detected,with the detection rate of 0.86％.Higher detection rates of Salmonella were found in the second and third quarters,with the rates being 1.41％and 0.89％respectively.The detection rate of Salmonella was found to be the highest in the group aged 0-3 years(1.90％).Occupation distribution showed that scattered children had the highest detection rate,being 2.20％.Among the suspected exposed food,the detection rate of Salmonella was found to be the highest in infant food(3.77％),followed by eggs and egg products(2.13％).Conclusion The epidemic peak of Salmonella infections was concentrated in June-September each year,with an obvious peak in summer and autumn.Special attention should be paid to Salmonella infections of infants and young children in the incidence peak.
